REFRIGERANTS


Circularity of used refrigerants: the solution for a viable future


Through its recovery, reclamation and repurposing processes, A-Gas, a global company specialising in Lifecycle Refrigerant Management (LRM), capture refrigerants and fi re protection gases for future re-use or destruction, preventing their harmful release into the atmosphere.


A


s certifi ed by the Copernicus Climate Change Service, 2024 was the warmest year on record globally and the fi rst calendar year that the


average global temperature exceeded 1.5°C above its pre-industrial level. As global temperatures rise, the use of air conditioners and other cooling applications is set to at least triple by 2050. There are currently 3.6 billion devices in use today, but this could be almost 14 billion by mid-century if cooling is provided to all those who need it (IEA data). In this context the role of refrigerants, with both their cooling and heating properties, will be essential to keeping the planet hospitable for communities worldwide: these gases are used in many industries and applications, from car air conditioning systems to supermarket chillers, playing a role in daily life globally. Equally important will be the role that the refrigeration, air conditioning and heat pump (RACHP) industry can play in providing environmentally responsible solutions.


Lifecycle management A-Gas’ business strategy is outlined by its purpose: to


protect and enhance the environment by eff ectively managing the lifecycle of refrigerants to build a sustainable future.


Since being founded in 1993 in Bristol, UK, it has supported its clients and partners on their environmental journeys by supplying lower global warming gases and actively increasing the circularity through Lifecycle Refrigerant Management (LRM), an environmentally conscious model that aims to reduce potential emissions from refrigerant gases with a high GWP: it focuses on avoiding and reducing refrigerant leaks by recovering used gas and increasing reclamation to reduce the need for virgin production of new refrigerants. According to Project Drawdown, LRM is one of the biggest opportunities to mitigate the risk of climate change. It predicts that these practices could save the equivalent of 57 gigatonnes of carbon dioxide emissions between 2020 and 2050. So how has the industry responded?

The Montreal Protocol, signed in 1987, banned the use of 100 Ozone Depleting Substances (ODS) in heating, ventilation, air conditioning and refrigeration (HVAC-R) equipment. Many industries replaced these with hydrofl uorocarbons (HFCs), which are not ozone depleting, but do still have a high Global Warming Potential (GWP). Later, the Kigali Amendment to the Montreal Protocol, signed in 2019, asked institutions to reduce the production and consumption of HFCs by 80% over the next 30 years. These regulations are a great start, but there is still the question of what to do with the high-GWP refrigerants currently in use when they reach their “end-of-life”: this is where a responsible LRM solution can add real value.


Circularity of used gas A-Gas’ LRM off ering is market-leading and wide-


ranging. By recovering, reclaiming and repurposing (or where necessary, safely destroying) used gas, it increases the circularity of these products while


minimising their potential impact on the atmosphere. The process consists of several stages. First, A-Gas’


expert technicians recover the refrigerant using custom-designed equipment. Then, the product is transported back to the local A-Gas facility for further processing. In many cases, this means reclaiming the refrigerant to AHRI 700 standards, extending the gas’ lifeline and creating an alternative that functions just as well as virgin products. Not only does reclamation reduce the risk of these gases being released into the atmosphere; it also reduces the need for virgin production and the associated emissions. The greater the amount of refrigerant that is recovered, reclaimed and repurposed, the greater the potential to reduce greenhouse gas (GHG) emissions from the cooling sector, in line with net-zero initiatives. When reclamation is not possible, refrigerants


are safely destroyed using UN-approved and TEAP- certifi ed technologies, permanently removing the potential for future emissions.
