Neste Oil has started producing NExBTL renewable diesel from waste fish fat at its Singapore refinery. The waste fat used by the company is generated when freshwater pangasius is processed for human consumption.
Waste fish fat complies with the strict sustainability requirements of the EU's Renewable Energy Directive and is also accepted as a raw material for renewable fuel in the US. The fish fat batch can also be traced all the way back to the fish farm.
The NExBTL renewable diesel produced from waste fish fat cuts greenhouse gas emissions by approximately 84% when compared to fossil diesel and calculated over the fuel's entire life cycle. Using NExBTL diesel also reduces tailpipe and fine particulate emissions significantly.
"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.
In addition to adding waste fish fat in the company’s raw material range, Neste Oil is continuing research and development on completely new types of raw materials.
"We are currently building Europe's first pilot plant to produce microbial oil from waste and residues-based raw materials at our Technology Center in Porvoo, Finland, and expect to complete it during the second half of this year," Lehmus adds.
