About GR2L

Gas recovery and Recycle Limited, GR2L, is a cleantech company based in the south east of the UK. We specialise in the recovery, purification and recycle of industrial purge gases used in high value manufacturing such as solar PV, microelectronics, 3D metals printing and aerospace heat treatments.

The company was founded in 2008 to commercialise novel Chemical Looping Combustive Purification, CLCP, technology jointly developed with Cambridge University, UK. The company’s flagship product, the ArgonØ, is a world first, utilising this technology to recycle argon purge gas from Solar PV ingot production furnaces. These exhaust gases are contaminated at the ~5,000ppm level with carbon monoxide and hydrogen along with traces of other combustive gases and are effectively removed to below ppm levels with recycle rates of 95% or better.

At one location, ArgonØ systems are recycling the argon purge gas from sixty CZ furnaces on a 24/7 basis at recycle rates of up to 97% saving the customer over $1.5million annually and reducing their carbon footprint by up to 1,800 tonnes of CO2 equivalent per year.
