Natural Refrigerants for a Sustainable Future

Industrial food production around the globe depends on natural refrigerants. Ammonia (NH₃), carbon dioxide (CO₂), and hydrocarbons such as propane (R290) make up the foundation of the technologies that support the global cold chain. Often called one of the world’s “century-proof” technologies, natural refrigerants have been used for over 100 years and continue to outperform synthetic alternatives in terms of energy efficiency and environmental impact.

Environmental and Health Risks of Synthetic PFAS Refrigerants

Modern HFO (hydrofluoroolefin) refrigerants are a growing contributor of trifluoroacetic acid (TFA), a per- and polyfluoroalkyl substance. These substances, otherwise known as PFAS “forever chemicals” introduce long-term PFAS pollution risks. This white paper examines the growing global concern over the role HFO refrigerants and their TFA byproducts play in the impending PFAS pollution disaster.
