Refrigerants in Thailand
Learn more about Tradewater's work collecting and destroying one of the largest stockpiles of old refrigerants found to date.
Destroying a massive refrigerant stockpile
In 2022, Tradewater launched its biggest international project yet–collecting and destroying a stockpile of old refrigerants with more than 1 million tons of CO2e.
Over a period of several years, the Thailand Customs Department seized a particularly large volume of Ozone Depleting Substances (ODS)—totaling more than 10,000 cylinders. The cylinders were stored in dozens of depots and warehouses throughout the country since their seizure, taking up space needed for other seized goods and slowly leaking into the atmosphere.
Tradewater’s mission to destroy potent ozone-depleting gases like these provided the Thailand government a permanent end-of-life solution and led to a unique public-private partnership between Tradewater, the Thailand Customs Department, WMS and others.
In October 2022, Tradewater representatives flew to Bangkok to guide the start of our operation, around the same time when WMS began collecting old canisters around Thailand on a truck headed to the destruction facility.
Working alongside Waste Management Siam, Tradewater successfully managed the seized stockpile of refrigerants, aggregated the gas, and destroyed it at a local incineration firm that meets all the environmental regulations and destruction requirements of the Montreal Protocol.

Project impact
Like many governments working hard to enforce the Montreal Protocol and protect the ozone layer, the government of Thailand seized ODS moving across its borders without proper permissions or documentation. Eventually, this massive stockpile grew to more than 120,000 kg of refrigerant and were at risk of leaking.
By partnering with Tradewater and working to destroy these ozone-depleting substances, we ensured that more than 1.1 million tons of carbon dioxide equivalent was permanently prevented from escaping into the atmosphere.
