Puragen (previously CPL Activated Carbons) has been awarded a Inexperienced Apple Award for Environmental Greatest Apply, recognizing the corporate’s novel course of for dealing with high-sulphur spent carbons from the biogas and biomethane sector, permitting them to be totally recycled, avoiding disposal by way of landfilling or incineration.
The corporate, a member of the REA, has developed the seemingly distinctive course of, which final 12 months additionally picked up the prize for Power Innovation on the Nationwide Recycling Awards. It addresses a serious problem within the biogas sector, specifically the necessity to take away poisonous and corrosive hydrogen sulphide fuel. Whereas activated carbon is the perfect obtainable know-how, the tendency of elemental sulphur to stay trapped throughout the media has tended to disqualify the usage of a standard strategy – thermal reactivation – to recuperate the spent carbon.
Puragen’s course of means high-sulphur spent carbon might be reprocessed on the group’s thermal reactivation facility within the UK. The reactivated carbon is prepared to be used in future purification functions, stopping hundreds of tons of waste every year.
