Cold storage of evergreen seedlings affected by global warming
Due to global warming, conifer seedlings are more often exposed to desiccation during snow-free winters. Overwinter cold storage allows to improve their survival, provided that...
Green roofs can reduce cooling demand in warm climate zones
The impact of green roofs on building energy performance was assessed in 15 climate zones. In most regions, the reduction in energy demand for cooling was greater than for...
Refrigeration innovations for the avocado market
The booming global avocado market calls for increasing standards of quality. Refrigeration technologies offer cutting-edge solutions for fruit ripening and seed preservation for future crops.
How to reuse the condensate water from air conditioners?
Review of the different uses of the condensate water rejected by air conditioners.
Green hydrogen production project in Namibia
In partnership with a French-German consortium, the Namibian government plans to develop a green hydrogen production facility. Although some of the funding may be secured as early as...
Kigali Amendment impact on global warming
The 8th Emissions Gap Report acknowledges the potential contribution short-lived climate pollutants (SLCPs) could make in the global effort to keep the planet’s warming well below 2 °C compared to pre-industrial levels.
Use of chillers in cannabis greenhouses
The legalisation of medical cannabis in several states in the US involves the development of new techniques to manage temperatures while reducing production costs.
Extracting cannabinoids using cryogenics
Several companies specialising in liquefied gases are developing systems operating with liquid nitrogen for cannabidiol (CBD) producers.
Reducing the economic costs of a direct-use geothermal heating system

Global warming potential (GWP) of HFC refrigerants
Using the latest updated data from UNEP’s RTOC 2022 report, we have compiled the 100-year GWP and 20-year GWP values of hydrofluorocarbon-based (HFC) refrigerants. Our table includes...
Cold storage conditions for fruits and vegetables
Practical recommendations for the cold storage of over 200 cultivars of fruits, vegetables and herbs (storage temperatures, relative humidity, storage time, controlled atmosphere...
Liquefied Natural Gas: production process and cold energy recovery
Liquefied natural gas (LNG) is natural gas that has been cooled to about -160 °C and turned into a liquid to facilitate transportation and storage. A typical LNG supply chain...
Additive manufacturing of regenerators for caloric cooling
In many areas of engineering, additive manufacturing allows the production of complex and multifunctional products that could not be manufactured using traditional methods. In the...
Ice cream manufacturing, environmental impact and market data
From a physico-chemical point of view, ice cream is a complex, frozen multiphase mixture. The manufacturing process includes several stages of freezing which are described in this...
Environmental impact of the ice cream industry
This summary document describes the environmental impact of ice cream manufacturing, which is mainly due to the energy consumption and refrigerants used.
Cryogenic nitrogen in the food and beverage industry
The adoption of cryogenic processes in the food and beverage industry is predominantly driven by liquid nitrogen (LIN), and it is the preferred candidate for food chilling and...
