ISCC redefines brown grease in updated feedstocks list

Singapore, 6 December (Argus) — The International Sustainability and Carbon Certification (ISCC) has clarified the definition of brown grease in a revised list of biofuels raw materials eligible for certification under the ISCC EU.

The ISCC confirmed that the category of brown grease or grease trap fat "shall exclusively be used for material that is removed from grease traps" in a system update released on 3 December, adding that "this category shall not be used for material that is removed from the sewage system".

This revised definition rules out the use of so-called "gutter oil", which is commonly collected from sewers and used as a biodiesel feedstock in China, from being classed as brown grease.
