PFAS ban proposal delayed
NORWAY: The European REACH restriction proposal to ban PFAS substances, which could include HFC and HFO refrigerants, has been delayed for six months to allow time to assess the applications.
The restriction proposal, which could have major consequences for the refrigeration and air conditioning industry, was originally due to be published in July but is now expected in January 2023. Its publication will be followed by a six-month stakeholder consultation period, with any final decision by the European Parliament and the Council of Ministers expected sometime in 2025.
Five EU member states – Germany, the Netherlands, Norway, Sweden and Denmark – jointly submitted the proposal to ban a wide range of PFAS chemicals in 2020. Some of the PFAS substances are known to be highly persistent in the environment, contaminating groundwater, surface water and soil, and causing serious health effects.
The European REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulation governs which chemicals can be manufactured and used within the EU. This regulation would, in practice, override the F-gas regulation.
Depending on the definition, PFAS substances number between 5,000 and 10,000 chemicals and are used in items such as non-stick cookware, waterproof clothing, food packaging and firefighting foams, in addition to refrigerants.
It is unclear which HFCs and HFOs, if any, might be included in the final proposal as the definition of a PFAS substance is subject to change during the process.
Under the current working definition, a PFAS is any substance that contains at least one fully fluorinated methyl (CF3) or methylene (CF2) group not directly attached to any hydrogen, chlorine, bromine or iodine atom.
This definition would include high GWP refrigerant R134a, as well as the low GWP HFO alternatives R1234yf and R1234ze. However, R32, for instance, which is now being used widely in smaller air conditioning units and is a vital component of many lower GWP blends, falls outside of the current definition.
