Neste Oil has started producing NExBTL renewable diesel from waste fat sourced from the fish processing industry at its Singapore refinery.

The fat comes from the gutting waste generated when processing freshwater pangasius farmed in Southeast Asia, after the fillets have been removed for human consumption.

This batch of waste fish fat complies with the strict sustainability requirements of the EU's Renewable Energy Directive, and the batch can be traced all the way back to the fish farm. Waste fish fat is also accepted as a raw material for renewable fuel in the US.

The NExBTL renewable diesel produced from the batch is claimed to cut greenhouse gas emissions by approximately 84% when compared to fossil diesel and calculated over the fuel's entire life cycle.

"It makes good ecological sense to use waste and sidestreams to produce advanced, premium-quality renewable fuel, which is why our goal this year is to increase the amount of by-products and waste we use as raw materials by hundreds of thousands of tons compared to 2011," says Matti Lehmus, Neste Oil's executive vice president, oil products and renewables.
