THE SCIENCE OF OZONE LAYER

Efficient air conditioning could reduce global warming

According to new research from the Institute for Governance and Sustainable Development (IGSD), the United States, improving the energy efficiency of air conditioners could save up to 100 billion tonnes of car-bon oxide (CO2) by 2050. In this report, IGSD highlighted the benefits of improving the efficiency of air conditioning units will slash future carbon emissions. The findings from the Lawrence Berkeley National Laboratory, the United States, also call for the parallel phase-out of hydroflourocarbon (HFC) refrigerants under the ongoing Montreal Protocol.

“Improving energy efficiency of air conditioners can at least double the mitigation from phasing down the refrigerant known as HFCs, as most Parties to the Montreal Protocol are eager to do through an amendment this year. Past phase-outs of refrigerants under the Montreal Protocol have catalyzed improve-ments in appliance energy efficiency on the order of 30 to 60%. Parallel efforts to set efficiency stan-dards and to ban imports of inferior air conditioners could ensure that efficiency was improved even faster,” said Durwood Zaelke at IGSD.

The research calculates a potential 1,200GW of electricity production could be avoided by improving global air conditioner efficiency, preventing up to 0.5 degrees of global warming alone. The group estimates by re-ducing the demand on energy intensive air conditioners countries could potentially prevent thousands of power plants being constructed worldwide. Industry experts have repeatedly claimed the UK and other na-tions will miss carbon emissions targets without sustained investment in cold energy. In 2014, the Carbon Trust called on the Government to seize the opportunity to become a world leader in developing low-carbon cooling technologies and lead the emerging global ‘cold economy’.

Simulation of polar ozone depletion

In a recent study, researchers from Massachusetts Institute of Technology, the United States, and Na-tional Center for Atmospheric Research, the United States, evaluated polar ozone depletion chemistry using the specified dynamics version of the Whole Atmosphere Community Climate Model for the year 2011. Re-searchers found that total ozone depletion in both hemispheres is dependent on cold temperatures (below 192 K) and associated heterogeneous chemistry on polar stratospheric cloud particles. Reactions limited to warmer temperatures above 192 K, or on binary liquid aerosols, yield little modeled polar ozone depletion in either hemisphere.

An imposed factor of three enhancement in stratospheric sulfate increases ozone loss by up to 20 Dobson unit (DU) in the Antarctic and 15 DU in the Arctic in this model. Such enhanced sulfate loads are similar to those observed following recent relatively small volcanic eruptions since 2005 and imply impacts on the search for polar ozone recovery. Ozone losses are strongly sensitive to temperature, with a test case cooler by 2 K producing as much as 30 DU additional ozone loss in the Antarctic and 40 DU in the Arctic.

A new finding of this paper is the use of the temporal behavior and variability of ClONO2 and HCl as indicators of the efficacy of heterogeneous chemistry. Transport of ClONO2 from the southern sub-polar regions near 55-65°S to higher latitudes near 65-75°S provides a flux of NOx from more sunlit latitudes to the edge of the vortex and is important for ozone loss in this model. Comparisons between modeled and observed total column and profile ozone perturbations, ClONO2 abundances, and the rate of change of HCl bolster confidence in these conclusions.

Oceanic bromine emissions weighted by their ODP

Researchers from GEOMAR Helmholtz Centre for Ocean Research, Germany, Norwegian Institute for Air Research (NILU), Norway, National Institute for Public Health and the Environment, the Netherlands, Brit-ish Antarctic Survey, the United Kingdom, University of Oslo, Norway, weighted oceanic bromine emissions weighted by their ozone-depletion potential (ODP). At present, anthropogenic halogens and oceanic emis-sions of Very Short-Lived Substances (VSLS) are responsible for stratospheric ozone destruction. Emissions of the, mostly long-lived, anthropogenic halogens have been reduced, and as a consequence, their atmos-pheric abundance has started to decline since the beginning of the 21st century.

Emissions of VSLS are, on the other hand, expected to increase in the future. VSLS are known to have large natural sources; however increasing evidence arises that their oceanic production and emission is enhanced by anthropogenic activities. However, researchers introduced a new approach of assessing the overall im-pact of all oceanic halogen emissions on stratospheric ozone. Seasonally and spatially dependent, global distributions are derived exemplary for CHBr3 for the period 1999-2006. At present, ODP-weighted emissions of CHBr3 amount up to 50% of ODP-weighted anthropogenic emis-sions of CFC-11 and to 9% of all long-lived ozone depleting substances.

The ODP-weighted emissions are large where strong oceanic emissions coincide with high-reaching convective activity and show pronounced peaks at the equator and the coasts with largest contributions from the Maritime Continent and West Pacific. Variations of tropical convective activity lead to seasonal shifts in the spatial distribution of the ODP with the up draught mass flux explaining 71% of the variance of the ODP distribution. Future climate projections based on RCP8.5 scenario suggest a 31% increase of the ODP-weighted CHBr3 emissions until 2100 compared to present values. The comparison of the ODP-weighted emissions of short and long-lived halocarbons provides a new concept for assessing the overall impact of oceanic bromine emissions on stratospheric ozone de-pletion for current conditions and future projections.

Ozone sensor launched

A physics professor and his student team from University of North Florida, the United States, have launched an ozone sensing device to the edge of space. According to the professor, it flew to the edge of space to a record-breaking height of 102,200 ft. It was launched this February, from Arizona into the earth’s stratosphere to detect the ozone, with the help of a commercial balloon space flight company and United Parachute, it was launched from Arizona into the earth’s stratosphere to detect the ozone. Student Ken Emanuel said detecting the ozone layer is important. “The depletion of the ozone layer is a phenomenon related to different gases that come from us as humans. So keeping an eye on the ozone layer is an important entity,” said Emanuel. Physics professor Dr. Nirmal Patel said the payload took about a six hour flight, and then landed in the New Mexico desert. The data from the sensors were collected and then downloaded for the team to study. Patel said depletion of the ozone layer would mean there would be more possibilities of harmful ultraviolet light passing through the stratosphere and hitting the earth. The team said they will continue to study the data over time and send more payloads to the edge of space. They hope to send another payload up in September 2015.

ODS PHASE-OUT IN INDIA

Stakeholders meet to phase-out HCFC and phase down of HFC

The Ozone Cell of the Ministry of Environment, Forest & Climate Change (MoEF&CC), Gov-ernment of India, recently organized two stakeholder consultations meetings to deliberate on the HCFC phase out and phase down of HFCs efforts. The meetings included: Stakeholders Consultation Meeting on India’s Amendment Proposal for Phase-down of HFCs was organized on 10 July, 2015, New Delhi, India; and Stakeholders Workshop on HCFC Phase-out Management Plan (HPMP): Stage - II, 13 August, 2015, New Delhi, India.

India became Party to the Montreal Protocol on substances that deplete the ozone layer on 19th June, 1992. Since then, India has been implementing phase-out of production and consumption of ozone-depleting sub-stances (ODSs) as per the Montreal Protocol schedule. The production and consumption of major ODSs like chlorofluorocarbons (CFCs), carbontetrachloride (CTC) and halons have already been phased out globally with effect from 1st January, 2010.

India has been making all round efforts to understand the issues relating to this subject since the beginning of the discussion on phase-down of HFCs under the ambit of the Montreal Protocol. Recently, India has submitted an amendment proposal for phase-down of production and consumption of HFCs using expertise and institu-tions of the Montreal Protocol and continue to include HFCs within the scope of UNFCCC and its Kyoto Proto-col for accounting and reporting of emissions.

New fire-fighting technology launched

Intimate Machines, India, has developed a new fire-fighting technology with incorporating water mist and CAFS (Compressed Air Foam System) technologies. The makers claims that the system is very cost- effec-tive and efficient to fight all common classes of fires without causing collateral damage to property or human beings due to its non-toxic nature.

The Karnataka Government fire service was the first in the country to try these systems to contain different types of fires successfully. Improvisations were carried out in the design to make it more compact, particularly to suit the roads in Kerala, where bigger vehicles cannot ply. The system is provided with high safety pressure non-return valves, radiant heat blocks, which give it an edge over the conventional firefighting systems.

Long term HFC emissions

The Council on Energy, Environment and Water (CEEW), India, along with the International Institute for Applied Systems Analysis (IIASA), Austria, has recently published a joint report on ‘India’s Long Term Hydrofluorocarbon Emissions’. The report finds that with eco-nomic growth and increasing per-capita incomes, more and more people will buy air-conditioners, re-frigerators, as well as personal vehicles. Higher penetration of all these technologies in the residential and commercial sectors forms the key driver of higher consumption and emission of HFCs. If HFC’s consumption is not phased down, total HFC emissions will increase to 500 MtCO2-eq in 2050.

This is based on the assumption that HFCs used as alternatives in developed countries will replace HCFCs in India as well. The biggest share of HFC emissions will be taken up by the residential and com-mercial cooling sectors (∼35 % and ∼28% respectively in 2050), followed by mobile air-conditioning in cars (∼15%), and then commercial refrigeration (14%). All other sec-tors put together will have a low share in India’s total HFC emissions. The HFC debate is part of a wider climate policy debate, and hence it becomes important to place India’s potential future HFC emissions in the context of India’s long term carbon dioxide (CO2) emissions.

The report finds that the share of global warming impact of HFC emissions compared to CO2 emis-sions in 2050 is highest for the commercial refrigeration sector, at 50%, which is mainly due to the high leakage rates experienced in this sector. This is followed by the commercial cooling sector and then residen-tial cooling sector, and the share of HFC’s global warming impact is over one-third for both these sec-tors in 2050. For mobile air-conditioning in cars, this figure stands at 22%. For all other sectors this share is fairly low, which is consistent with findings from other international assessments. In terms of HFC’s contribution to India’s overall greenhouse gas emissions, HFCs contribute 5.4% of India’s combined CO2 and HFC emission related global warming impact in 2050.

IN THE NEWS

Japan excludes HFOs from new emissions law

The Japanese Ministry of the Economy, Trade and Industry (METI), have placed the Hydrofluoroolefins (HFOs) 1234yf, 1234e and 1233zd outside Japan’s strict new fluorocarbon emissions control laws. The decision by METI to exclude the HFOs from the new regulation, which took effect on April 1, 2015, means that they are not regulated in terms of curbing emissions or leakages, recovery and destruction for disposal, etc.

The decision was welcomed by HFO manufacturer Honeywell, the United States, which sells the new gases un-der its Solstice brand for use as refrigerants, propellants and solvents. It means that HFOs now join hydrocar-bons and carbon dioxide in Japan’s non-flon category. “Honeywell is proud to help Japan drive actions that will prevent global warming. The environmental superiority of our Solstice products has enabled this non-flon designation, which will help drive their adoption in Japan,” said Katsuyuki Takise, at Honeywell.

R452A as R404A alternative

Compressor manufacturer Tecumseh, the United States, has backed refrigerant R452A as a mid-term alternative to R404A in medium and low temperature commercial refrigeration. Tecumseh says it sees the low discharge temperatures exhibited by refrigerant R452A as extremely important mainly due to its experi-ence with hermetic compressor reliability. OEM customers interested in obtaining R452A compatible com-pressors for performance and/or field test samples are advised to contact their Tecumseh sales repre-sentative.

In parallel, Tecumseh is evaluating the availability of R452A compatible compressors and condensing units via its network of authorised wholesaler distributors with a tentative launch date of early 2016. Tecumseh says it is con-tinuing to devote resources to the evaluation of its products for use with low GWP refrigerants including, the de-termination of a sustainable long-term solution. R452A, being sold by DuPont, the United States, as XP44, has a GWP of 2140 – a little over half that of R404A. Comprising R32, R125 and R1234yf, it has already been adopted by a number of transport refrigeration companies as a replacement for R404A.

Tecumseh is backing the refrigerant as an interim solution for medium and low temperature applications ranging in capacity from ½ hp to 30hp. A non-flammable A1 refrigerant, it uses the same POE oil as R404A. Testing has confirmed that refrigerant R452A provides nearly the same capacity and efficiency as R404A across an evaporat-ing temperature range of -25°C to -10°C. However, for evaporating temperatures below -25°C, R452A exhibits a slight reduction in capacity (up to 9% capacity drop at -35°C). For self-contained commercial refrigeration equipment with capacities less than ½hp, Tecumseh continues to support propane (R290) as the preferred choice.

China promotes natural refrigerants against HCFCs

China has given ‘its clearest indication yet’ that it is planning to promote natural refrigerants as a substitute for HCFCs after publishing a list of recommended substitutes for Hydrochlorofluorocarbons (HCFCs) which feature nearly all natural refrigerants, rather than other low global-warming-potential (GWP) alternatives. According to market intelligence firm CCM, China, the publication of the list is likely to be followed by more sub-stantial policies promoting natural refrigerants and foam-blowing agents over the coming years. The First Cata-logue of Recommended Substitutes for HCFCs has been published by China’s Foreign Economic Co-operation Office, Ministry of Environmental Protection (FECO).

FECO officials announced that the Catalogue was the product of extensive research into policies to transition away from HCFCs and to fulfil China’s obligations under the Montreal Protocol. Of the twelve substitutes included in the Catalogue, ten are natural chemicals and only one is an HFC – R32 – which CCN contends is a clear indication of the government’s mind-set as China begins the move towards eliminating HCFCs. The Catalogue is intended to be a general indication of the Chinese government’s intentions and will not include any practical poli-cies to support natural substitutes for HCFCs. However, recent history suggests that more practical measures are likely to follow in the near future.

When China announced that it intended to promote R290 as a replacement for R22 in domestic air conditioners in 2012, several supportive policies were introduced soon after, including an agreement to help air conditioner manufacturers overhaul their production lines in 2013, new subsidies for the production and marketing of air conditioners using R290 from 2014, and the introduction of a new ‘Environmental Protection and Low Carbon Label’ in 2015 to encourage consumers to choose green air conditioners. According to CCM’s research, severe overcapacity has made life increasingly difficult for HFC producers in China.

Bhutan controls illegal ozone depleting chemicals

On February 2015, the Customs officials of Bhutan confiscated 4 cylinders of HCFC-22 gas (also known as R-22) that were imported from India, without permit from the government. Permit to import the R-22 gas was found missing upon physical verification by the customs officials. The customs officials confiscated the con-signment and forwarded the case to the Department of Revenue & Customs (HQ) and the National Envi-ronment Commission (NEC) for formal instruction and advice. Hydrochlorofluorocarbon (HCFC) is a controlled substance under the Montreal Protocol on substances that deplete the ozone layer. Its production as well as trade are restricted world-wide and only allowed with prior license and permit

After a careful review of the case, the authorities jointly decided to request the importer to re-export the cylin-ders with the ozone-depleting substances (ODS) to the original supplier in India. In line with the Sales Tax, Customs and Excise Act of the Kingdom of Bhutan, 2000, the Bhutanese importer was made responsible for covering the cost of the re-export including travel expenses of a designated Customs officer to oversee and confirm the return of the goods. Further, under the Offences and Penalties of the Rules and Regulation of ODS 2008, the importer was charged with a penalty of Bhutanese Ngultrum (BTN) 5,000 as the first-time offence.

New program targets earth-friendly refrigerants

The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) and the United Nations Environmental Programme (UNEP), have agreed to work together on the development of a global qualifications program for refrigerant supply chain networks in response to the depleting ozone layer. An exchange of letters was com-pleted between the two organizations during the Montreal Protocol Open Ended Working Group meeting in France on July 23. Known as “refrigerant driving license” (RDL), the program will target the sound and safe management of refrigerants and accelerate the transition to greener types.

“Working with UNEP and developing the RDL is one very important aspect of the indus-try’s focus on ensuring the proper, safe, and environmentally sound management of refrigerants. AHRI’s relationship with UNEP will provide an excellent platform for working with other associa-tions and institutes, creating a global network to support the safe handling of refrigerants,” said Stephen Yurek at AHRI. In addition to reaching targets instigated by the Montreal Protocol – an interna-tional treaty to protect the ozone layer – the agreement will also advance the skills of field specialists as new technologies surface.

REFRIGERATION/AIR-CONDITIONING

Next-generation centrifugal chillers

Mitsubishi Heavy Industries Ltd. (MHI), Japan, has developed a new series of centrifugal chillers, called the ETI-Z Series, that use a new low-global warming potential (low-GWP) refrigerant, HFO-1233zd(E). The ETI-Z Series are the first small-size centrifugal chillers to adopt the new refrigerant. According to MHI, the ETI-Z Series carries the fundamental product concept of high performance combined with compact size. Models in the new ETI-Z Series have a cooling capacity with a range of 80 to 700 refrigeration tons (RT). High perform-ance is achieved by reducing motor drive-energy loss through the adoption of a compressor with high-speed direct motor drive, the elimination of step-up gear, and use of fewer bearings.

HFO-1233zd(E) has the same low GWP as carbon dioxide (CO2), i.e., 1, and an ozone depletion potential (ODP) of 0. Owing to this minimal impact in terms of greenhouse gas emissions and no impact with respect to ozone depletion. This means that HFO-1233zd(E) is not regulated in terms of curbing emissions or leakage, recovery and destruction for disposal, etc. Compared to MHI’s current refrigerant, however, the volume of refrigerant gas is about five times greater. However, in the ETI-Z Series, a more compact size has been realized by applying the latest blade shape, increasing the motor speed, and by adopting and optimizing the arrangement of the high-performance tubes.

The microcomputerized control panel features a new board that enables more precise control, thanks to in-creased speed of the central processing unit (CPU), to support energy-saving operation of the chiller. The adoption of a touch panel type liquid-crystal display both enhances operability while also improving functions that support maintenance of the main unit. Going forward, MHI plans to expand its lineup of centrifugal chillers featuring the new refrigerant by progressively developing and launching models up to 1,500 RT, including fixed-speed models.

Low GWP R513A chiller launched

Trane, the United States, a subsidiary of Ingersoll Rand, has launched air-cooled chiller named Sintesis which offers low GWP refrigerant R513A as an option. The intention to include an R513A option in addition to traditional R134a on the new chiller range was first revealed in January. Announcing that these new chill-ers are now available for order in Europe, the Middle East, North and Latin America, Ingersoll Rand presi-dent said: “Through the new, expanded Sintesis chiller portfolio, Trane now offers building owners and businesses more choices regarding how and when to reduce greenhouse gas emissions.”

In Europe and the Middle East, the new Trane Sintesis chillers are available in sizes of 245 up to 450 (cooling ca-pacities from 300 to 1600 kW). The chillers reach 1.6MW of cooling capacity at Eurovent rated points and supple-ment the original 090 to 205 sizes introduced by Trane in 2014. In North and Latin America, Sintesis chillers in sizes from 115 to 215 ton are available now, with the 230 to 500 ton models available later this year.

The Sintesis is said to achieve industry leading EERs and ESEERs. It is also said to use up to 40% less refrigerant than traditional tube/fin and flooded heat exchanger technology due to the micro-channel con-denser coil and the compact, high-performance, integrated, low charge (CHIL) evaporator design. Already incorporating measures to reduce noise and improve acoustics, a user-selectable noise-reduction mode is also available to help comply with nighttime and weekend neighbourhood noise restrictions.

New generation refrigeration units

Emerson Climate Technologies, the United States, has announced the next generation of Copeland EazyCool ZX refrigeration with significant upgrades. The new EazyCool ZX features a new electronic control-ler which enables precise adjustment of suction and condensing pressures and shows all relevant parame-ters on a LED display. Additionally, the hinged front door has a quick check window to view the system status without opening the unit. The new models are claimed to keep the compact dimensions of the estab-lished former generation.

The fan blades are sound optimized with controlled rotation speed and the use of highly efficient Cope-land Scroll compressors reduces power consumption and saves operation costs. Additionally, multiple refrigerant approvals including R134a, R407A and R407F increase flexibility and ease logistics as one model fits most applications – especially a benefit for wholesalers and installers. All important system settings, such as fan speed, can be adjusted to exactly match the application requirements.

The new universal controller also provides electronic motor protection of the compressor and real time commu-nication via Modbus. Galvanized panels and coated condensers ensure protection against corrosion and reliable operation even under tough conditions. With short installation time, superior efficiency and high reliability, this new generation helps customers to reduce life cycle costs to a minimum.

Advance low-GWP ammonia refrigeration systems

Danfoss, the Unites States, a leading manufacturer of high-efficiency electronic and mechanical compo-nents and controls for air-conditioning, heating, refrigeration, industrial and water systems, showcased ad-vanced, low-GWP direct expansion (DX) ammonia refrigeration systems at ATMOsphere America 2015, held on 25-26 June in Atlanta. During the conference more than 300 industry leaders gathered to discuss current and future natural refrigerant market trends and related technology innovations and regulatory issues in North America. “Ammonia is a proven refrigerant, with some of the best heat transfer characteristics of all re-frigerants,” said Terry Chapp, at Danfoss.

Ammonia is a natural refrigerant with zero ozone-depletion potential (ODP) and zero global warming poten-tial (GWP). It is also inexpensive and plentiful, making advanced DX ammonia systems an attractive option for industrial refrigeration system designs. At the same time, ammonia is toxic – and, in unusual cases, can be flammable. During the planning stage, the refrigeration subcontractor presented two options for the ware-house: a pumped recirculated liquid (PRL) ammonia system and a DX ammonia system. A conventional PRL design would require about 25,000 pounds of ammonia for phase I and more for phase II, putting the facility over the 10,000-pound threshold that requires a Process Safety Management/Risk Management Plan (PSM/RMP).

However, the DX system would reduce the total ammonia charge for phases I and II to significantly less than 10,000 pounds, the PSM/RMP threshold. Final analysis of the two estimates showed the DX sys-tem saved approximately $100,000 for the total refrigeration system first cost. When added to the advantage of lower ongoing cost, it made the DX system an easy choice. The JCS system also features a DX evaporator that provides proper liquid distribution at the coil inlet and enhanced inside tube surfaces, which causes liquid to wet the entire tube surface with refrigerant.

New refrigeration system

A refrigeration system using the low global warming potential (GWP) HFO R1234ze in a cascade sys-tem with carbon dioxide (CO2) has been successfully applied for the first time at a bakery in Ger-many. Mindful of the F-gas regulations and the HFC phase-down in Europe, Bäckerei Maurer of Win-nenden, turned to this untried option when looking to provide refrigeration for its latest factory production area. The result is what is claimed to be the first industrial installation that combines Honeywell’s Sol-stice ze brand R1234ze in a cascade system with CO2. The Maurer Bakery is a family bakery and retail business preparing bread and other products to be sold in the company’s network of 42 bakery-cafe outlets in Germany.

The company took advice from its refrigeration partner, IceCool, a specialist in bakery, catering and food re-frigeration. IceCool worked in collaboration with Dutch system-builder ECR Nederland and refrigerant sup-plier Climalife Holland to come up with the low GWP solution. Maurer and IceCool together designed a cas-cade system that could operate efficiently and accommodate the different pressure profiles of the refriger-ants. ECR-Nederland BV has a strong reputation for customised solutions, notably by applying very powerful 3D design modelling wrapped inside a full project package, and this approach was harnessed to ensure that Maurer was able to evaluate system performance and approve the overall design.

Climalife had previously participated in a number of field trials involving Honeywell’s Solstice ze and highlighted the innovation as a future-proofed, lowest possible GWP solution. The system design was opti-mised to the lower pressure of Solstice ze versus the traditional refrigerant R134a. As Solstice ze is mildly flammable, IceCool checked with a notified body about ATEX compliance, who assessed that given the very low risk of Solstice ze in that system design, ATEX extra measures were not needed. The result is a system that combines Solstice ze for both direct expansion in medium temperature in a cascade with CO2 for low temperature.

Odourless hydrocarbon based solvent cleaner

The new ‘Accepta 3548’ developed by Accepta, the United Kingdom, is a very highly re-fined odourless hydrocarbon based solvent cleaner that is free from aromatic species. It is scientifically for-mulated for use where odour, toxicology and taint are unacceptable and as a replacement for 1,1,1 Tri-chloroethane and other chlorinated and fluoro-chlorinated solvents. This specialised formulation has been developed to replace such common place materials as kerosene, white spirit and ozone-depleting solvents for use in working environments where odour, toxicology and taint are unacceptable. Technically advanced, Accepta 3548 is also intended as a specialised replacement for 1,1,1 Trichloroethane and other chlorinated and fluoro-chlorinated solvents, scheduled for discontinuation under the Montreal Protocol.

Specialty cleaner for removing stains

TechNova, India, has introduced AniKleen Sol, a specialty cleaner for removing aqueous overprint var-nish (OPV) deposits from rollers and blankets with minimal effort. Most printers typically use the conventional method of cleaning by using a mixture of isopropyl alcohol (IPA) and water to scrub the blankets and rollers clean. “Not only does this conventional method result in a lot of wasted energy and time, but it also does not clean the blankets and rollers effectively, resulting in inconsistent print jobs,” said Milind Kale, at TechNova.

Kale added, “TechNova has recognised this need and has introduced AniKleen Sol which works on the principle of chemical action, instead of a mechanical action, to clean water-based OPVs from rollers and blankets.” AniKleen Sol, when applied to the affected areas, adequately wets and dissolves the dried OPV deposits making the cleaning process easier and faster. This in turn reduces machine downtime and improves productivity. However, this solution is suitable for cleaning aqueous varnish from rollers that use the duct varnish process for coating. When using process colour inks, normal wash is recommended.

Vapor degreasing cleaning process

KYZEN Corporation, the United States, and cleaning equipment manufacturer Controls System Design, the United States, has jointly developed the DuoSolvent™ cleaning process that works within a vapor degreaser and eliminates the need for a water rinse. DuoSolvent™ technology creates the benefits of a vapor degreasing process without the hazards. The DuoSolvent™ process incorporates an engineered cleaning solvent that matches a wider range of flux residues and is then rinsed with an environmentally friendly rinsing solvent.

A unique feature of the DuoSolvent™ process is a secondary distillation process that removes the sol-vating agent drag out in combination with soils that are accumulated in the rinse fluid boil sump. The parts are rinsed with a fluorinated rinsing fluid. The vapor blanket formed from the rinsing fluid is condensed, drained into the final rinse tank and overflowed back into the boil sump. This waterless process provides the beneficial properties that vapor degreasing while overcoming health, cleaning, and material limitations asso-ciated with common vapor degreasing solvents used today.

Plasma etching system

Plasma Etch Inc., the United States, a leader in plasma innovation, has released new details about the workings of the Magna plasma etching system. The Magna series utilizes the newest technologies available, eliminating the need for CF4 gas, a harmful contributor to ozone layer depletion. CF4 gas is presently used by PCB manufacturers using plasma etching systems across the globe. Oxygen is intro-duced from an on-board oxygen generator; meaning no cylinders.

The machine uses a dry vacuum pumping system that is maintenance-free, requiring no oil. Magna promises considerable yearly operating cost savings as compared to conventional large plasma treatment systems. In addition to being green, Magna boasts faster etch rates than conventional systems and better etch uniformity due to a rotating carousel fixture. The device has a large capacity; eight 19” x 28” panels can be processed per load cycle, with both sides processed simultaneously.

In 1987, Plasma Etch invented a true plasma process temperature control system allowing a consistent temperature to be maintained throughout the plasma cycle. The temperature is controlled completely inde-pendently of the plasma process. This temperature control system is an integral part of Magna’s ability to etch without CF4 or supplied oxygen gasses. The pattern of innovation at Plasma Etch has al-lowed implementation of the world’s first truly green plasma etching system.

ODS-free rotational molders

Stoner, the United States, with its new RotoFlow high-efficiency mold coating is making the process easier for rotational molders to go with the flow for rotomolded polyolefin and nylon resins. Inserts, tight radii, threads and deep cavities are often hard-to-fill areas in rotationally molded parts and can result in weak or defective molded components, often rendering them unusable. RotoFlow increases the flow of polyolefin and nylon resins into these difficult-to-reach areas, producing a fully molded part and nearly eliminating voids, pinholes, bridging, thinning and static lines on the surface.

According to Stoner, users have reported higher part quality, increased production efficiency and reduced operational waste, allowing them to achieve higher production goals in less time. RotoFlow does not contain ozone-depleting substances (ODS) or chlorinated solvents. It can be sprayed directly onto the internal mold surface and is suitable for use with most metals.

Innovative watermist technology

Developed by Plumis Ltd, the United Kingdom, the Automist® is a simple, retrofittable, sprinkler-alternative for full room active fire protection. In the event of a fire, the system is triggered automati-cally by a heat alarm or a fire panel output. Heat detection is recommended for kitchens in Approved Docu-ment B, and effectively eliminates nuisance activation. Unlike conventional sprinklers, Automist can be stopped manually by pressing a button on its control panel.

As Automist® uses much less water than a traditional sprinkler system, water damage in the event of activation is minimised. Where desired, manual activation can also be provided through a manual call point. Once triggered, a small pump drives mains water through the unique nozzle unit, quickly filling the room volume with a dense fog. Water mist removes heat and displaces oxygen from the fire zone, resulting in fire con-trol, suppression or extinguishment.

Sustainable alternative to polystyrene

Biopolymer Network, New Zealand, has received a patent for a new method of producing E-PLA bio-foams from commercially available PLA beads using a novel carbon dioxide (CO2) foaming tech-nology. This technology can be used to produce both foamed beads and moulded shapes and products such as insulation, packaging and speciality components.

This technology has been used to produce moulded E-PLA product on standard commercial polystyrene moulding equipment and tests on these products have shown similar performance to polystyrene for both impact resistance and insulation. Zealafoam is an environmentally-friendly polylactic acid foam and is con-sidered as a sustainable alternative to petroleum-based polystyrene. Under development for the past nine years, Zealafoam is being tested by a large US global company for an, as yet, undisclosed product.

The bio-based plastic used in Zealafoam is derived from corn starch and the novel patented process in-volves introducing CO2 as a blowing agent which expands the small bioplastic beads so they can be moulded into different shapes and products. One of its main benefits is that Zealafoam can be produced on the same machinery used to make polystyrene. Contact: Biopolymer Network, 49 Sala Street, PO Box 1206, Rotorua 3040, New Zealand.

New foam blow molding process

At the recent NPE2015 show in Orlando, W. Müller USA Inc., the United States, the maker of blow molding extrusion heads launched its foam blow molding process, after more than a year in devel-opment. “At NPE, we started talking to selected customers about our new blow molded foam technology for packaging. They had a lot of questions about things like physical properties, and I had to tell them that we’re still at the very beginning, in terms of application development. But we have proven that the process works very well,” said Wolfgang Meyer at W. Müller. The process uses a special head design for three-layer coextrusion with solid inner and outer skins and a foamed center.

The machine’s main horizontal extruder provides the middle foamed layer, while two separate ver-tical extruders provide the skins. (A single extruder would suffice for both skins, but two extruders allow savings by putting color and additives in just the outer layer.). It uses no chemical blowing agent – only talc as a nucleating agent, so it is acceptable for food packaging. Another feature of the head – which is retrofittable to any brand of continuous-extrusion machine – is a “pineapple” dynamic mixer to disperse the gas. Higher mixer speed yields finer cell structure. Cell structure thus can be controlled independently of extruder speed, unlike other processes.

FUMIGANTS

New machines to replace methyl bromide

The Thailand’s Ministry of Agriculture and Cooperatives, will be supplied with machines for the disinfestation of weevil’s eggs through the dielectric method, under a collaboration between the Agri-cultural Research Development Agency (ARDA), Thailand, and Eureka Design Public Company Limited, Thailand. Chavalit Chookajorn, Permanent Secretary for Agriculture and Cooperatives, has signed an agreement over technology licensing right between the ARDA and Eureka Design Plc.

The dielectric disinfestation machine would replace the more costly fumigation method via methyl bromide. Methyl bromide is also being banned by several countries starting this year. According to Mr. Chavalit, the dielectric heating machine would destroy all weevils and eggs in rice without leaving behind any contami-nants. He said the new technology would create an advantage for Thai rice in the global market, and allow Thai rice to be exported as a chemicals-free product.

Scientists study organic fruit and food safety

Scientists at Washington State University (WSU), the United States, have found that ultraviolet C (UVC) light is effective against foodborne pathogens on the surface of certain fruits. The findings are expected to be welcome news for organic fruit processors who seek alternatives to chemical sanitizers and must also com-ply with the U.S. Food Safety Modernization Act to help prevent food borne illnesses. After learning from or-ganic farmers and food processors about a lack of sanitizing options, WSU food safety specialist Shyam Sa-blani and his colleagues looked into alternatives and decided to explore UVC light. It has a shorter wave-length than ultraviolet A or B light. The study has been published in the International Journal of Food Mi-crobiology.

“UVC radiation is present in sunlight; however, it is completely absorbed by the ozone layer and Earth’s atmosphere. It has germicidal properties and can be effective against bacteria, mold and vi-ruses,” said Sablani. UVC light, which cannot penetrate opaque, solid objects, can be effective in sanitizing surfaces. The technology, which has been around for several years, has been used to effectively sanitize food contact surfaces as well as drinking water and contaminated air. It works on microorganisms by destroying nucleic acid and disrupting their DNA. But the light didn’t affect the chemical or physical quality of the fruit in the study.

Researchers exposed apples, pears, strawberries, raspberries and cantaloupe to different doses of UVC to determine how effective the pathogen-killing light was against a mix of strains of E. coli and listeria. They found that the light can inactivate up to 99.9 percent of pathogens on apples and pears. However, lis-teria was more UVC resistant than E. coli. The UVC light inactivated 90 percent of pathogens present on rough-surfaced fruit. Rough surfaces of strawberries, raspberries and cantaloupe offer places where pathogens can literally hide, reducing the effects of UVC light. Adding UVC lamps to a fruit packing line does not require major modification. UVC lamps enclosed behind protective barriers can be easily set up in a tun-nel that exposes fruit to the light as it passes on a conveyor belt.

Alternative methods for disinfesting chestnuts

Recently a team of researchers from Northwest A&F University, China, Xinjiang Academy of Agri-cultural Sciences, China, San Joaquin Valley Agricultural Sciences Center, the United States, and Washing-ton State University (WSU), the United States, studied the alternative methods for disinfesting chestnuts. They found that chemical fumigation has been widely used to control insects in postharvest chestnuts but is inherently dangerous when using fumigants.

The purpose of this study was to validate application of radio frequency (RF) treatments for disinfesting chestnuts as an alternative to chemical fumigation. A practical process protocol was developed to control insect pests in chestnuts using a 27.12 MHz free-running oscillator RF system. Fifth-instar yellow peach moth, Conogethes punctiferalis, more heat tolerant than chestnut weevil, Curculio elephas, under three temperature and time combinations using a heating block system, was selected as the targeted insect to validate the RF treatment protocol.

Mortality of fifth-instar C. punctiferalis increased with increasing holding time at 55°C using RF heating and reached 100% while holding in hot air for at least 5 min. Furthermore, there was no significant quality difference in color, fat, firmness, moisture content, protein, and soluble sugar content of chestnuts observed between RF treatments and controls. RF treatment methods hold potential to scale up for industrial applications of disinfesting chestnuts. The study has been published in the Journal of Stored Products Research.

Evaluation of methyl bromide alternatives efficacy

In a study, researchers from Chinese Academy of Agricultural Sciences, evaluated methyl bromide (MB) and other alternatives for suppression of Fusarium spp., Phytophthoraspp., and Meloidogyne spp. and their influence on soil microbial communities. Both Fusarium spp. and Phytophthora spp. were significantly reduced by the MB (30.74 mg kg-1), methyl iodide (MI: 45.58 mg kg-1), metham sodium (MS: 53.92 mg kg-1) treatments.

MS exhibited comparable effectiveness to MB in controlling Meloidogyne spp. and total nematodes, followed by MI at the tested rate. By contrast, sulfuryl fluoride (SF: 33.04 mg kg-1) and chloro-form (CF: 23.68 mg kg-1) showed low efficacy in controlling Fusarium spp., Phytophthora spp., and Meloidogyne spp. MB, MI and MS significantly lowered the abundance of different microbial populations and microbial biomass in soil, whereas SF and CF had limited influence on them compared with the control.

Diversity indices in Biolog studies decreased in response to fumigation, but no significant difference was found among treatments in PLFA studies. Principal component and cluster analyses of Biolog and PLFA data sets revealed that MB and MI treatments greatly influenced the soil microbial community functional and structural diversity compared with SF treatment. These results suggest that fumigants with high effectiveness in suppressing soil-borne disease could significantly influence soil microbial community. The study has been published in the journal PLoS One.
