In Malaysia, Litrocom collects used cooking oil (UCO) from frying and deep-frying, from restaurants, hotels, food industries and even households. it is filtered at their site in Johar and then sold to refineries which can use the UCO to produce sustainable fuels. The biggest buyer is Finnish Neste, that ships it to its refinery in Singapore, where it is turned into HVO that can replace fossil diesel and SAF that can replace fossil jetfuel. Since this UCO would otherwise be just waste, often clogging up sewage systems, the efficiency, sustainability and climate gains compared to the fossil fuels replaced are tremendous - estimated at around 90% CO2 emissions reductions. At the same time, local jobs are created and households and others gain an income from their waste oils.
