PSA Corporation (PSA) and Ocean Network Express (ONE) have conducted successful trials of recycling reclaimed refrigerant gas from reefer containers. 

Refrigerant gases are harmful greenhouse gases with a high global warming potential (GWP). The use of these gases is now controlled, with legislation in place around the world, including in the EU and the UK. 

According to PSA and ONE, recycling refrigerant gas successfully saves around 4,000kg of carbon emissions per reefer, assuming 3kg of R134a refrigerant gas per reefer, comparable to the emissions from driving a typical internal combustion engine car for nearly a year. 

PSA recovers refrigerant gas that has been discharged from reefer cooling systems during maintenance and repair work, cleans, processes, and certifies it before it is reused and pumped back into the reefers. 

Following the success of the trials, PSA intends to expand the green project to include other shipping lines and partners. 

“Close collaboration with a shared purpose is key to achieving a resilient and sustainable global supply chain ecosystem,” stated Mr Ong Kim Pong, Regional CEO Southeast Asia, PSA International.  

“PSA is delighted to have ONE coming alongside us in our strive to minimise the environmental impact of our operations. With the strong and steadfast support of our customers and partners, PSA is one step closer in ‘greening up’ supply chains and shaping the future of Singapore as an innovative and sustainable global maritime hub.”
