For 16 years, Partners in EPA’s RAD program have leveraged best environmental practices to collect and dispose of old refrigerated appliances such as refrigerators and freezers, window air conditioners, and dehumidifiers.

Italian manufacturer Zudek’s air-cooled, low-charge ammonia/NH₃ (R717) chiller has improved the energy efficiency ratio (EER) of a cooling system at a pharmaceutical site in Belgium, by 20%, compared to its previous HFC-based unit.

Scientists at a German research organisation are looking to cool buildings using a “programmable” insulation foam that can change shape depending on the temperature.

Many causes of air pollution, such as vehicle emissions and industrial fumes, are more apparent outdoors, but air quality indoors can be equally poor. It can be a particularly acute problem in enclosed spaces like classrooms, with children being more vulnerable to the effects of pollution.

After recent heavy investment in the expansion of their capacity in the US, A-Gas is completing the construction of its latest refrigerant separation towers at its Rhome, Texas plant, located outside of Dallas/Fort Worth. The expansion project, which began earlier this year, represents A-Gas’ continued commitment to delivering cutting-edge technology aimed at substantially increasing the quantity of reclaimed refrigerant gases, bringing new capacity online in 2023 to supply the US.

The International Energy Agency (IEA) has described heat pumps as “indispensable” in efforts to cut emissions and has urged policy makers worldwide to put their weight behind the technology.

Supermarket refrigeration is one of the leading sources of super-polluting hydrofluorocarbon refrigerant (HFC) emissions. Together with North American Sustainable Refrigeration Council (NASRC), U.S. supermarkets are taking steps to characterize and proactively reduce refrigerant leaks over the lifespan of refrigeration systems.
