The Renewable Fuels Association this week responded to a request for information from the California Air Resources Board urging them to do more to ensure the integrity of imported waste cooking oil (UCO) and tallow in order to produce biomass-based diesel in accordance with the state’s Low Carbon Fuel Standard, according to a report on EnergyAgwired.com.
The RFA noted that according to CARB data on California’s fuel consumption, the use of biomass-based diesel (BBD) produced from UCO doubles and the use of BBD produced from tallow triples from 2019 to 2023, and that some in the marketplace believe there may be questions about the source and composition of these feedstocks.
Many biofuels market participants and other observers are concerned about the legality of importing ‘waste’ feedstocks and question whether some UCOs contain palm oil and/or other mislabelled fats, oils and greases,’ said Scott Richman, RFA’s chief economist.
