Regulated stewardship coming soon for synthetic refrigerant industry
By Jason Richards – National Programme Manager – Chemicals, 3R Group In the race to combat climate change a lot of emphasis is put on CO2, and with good reason, but there is another widely used group of gases which are thousands of times more potent at warming the planet. Synthetic greenhouse gases, such as synthetic refrigerants (sometimes called F-gases), are used in everything from vehicle air conditioning to heat pumps, supermarket and corner store fridges, and industrial-scale cooling and freezing. While they only account for 2% of New Zealand’s emissions their potency means, globally, properly managing them is one of the most effective ways to tackle climate change. In July 2020 Government declared synthetic refrigerant gases, and the equipment that contains them, from consumer equipment like heat pumps and car air conditioning units to retail and industrial refrigeration systems, as a priority product. This means a regulated product stewardship scheme will have to be established, encompassing all of industry to manage the gases. Product stewardship manages the collection of products at the end of life so they can be reused, recycled or properly disposed of. In the case of synthetic refrigerants, proper disposal through high-heat incineration is currently the best pathway. SF6 is included Also included in the stewardship will be SF6 (sulphur hexafluoride) gas, which is found in equipment used to distribute electricity. It is the most potent greenhouse gas known to man, being over 20,000 time more effective than carbon dioxide at trapping heat. What is the current situation? New Zealand has had a voluntary stewardship scheme for synthetic refrigerants since 1993 operated by The Trust for the Destruction of Synthetic Refrigerants (RECOVERY). Between then and October 2022 it has prevented 1,236,000 tonnes of CO2eq greenhouse gas emissions, in addition to 36,000 tonnes of avoided ozone depletion […]
