Neste Oil produces renewable diesel in Singapore from waste fish fat
Neste Oil says it has expanded the range of renewable raw materials it uses by producing NExBTL renewable diesel at its Singapore refinery from waste fat sourced by the fish processing industry.
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.
As with other renewable inputs used by Neste Oil, the batch of waste fish fat complies with sustainability requirements of the EU's renewable energy program.
The batch can be traced back to the fish farm. Waste fish fat is also accepted as a raw material for renewable fuel in the US, Neste Oil said.
The NExBTL renewable diesel produced from the batch cuts greenhouse gas emissions by approximately 84% when compared to fossil diesel and calculated over the fuel's entire life cycle, the company said.
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," said Matti Lehmus, Neste Oil's executive vice president for oil products and renewables.
"In addition to focusing on waste and sidestreams, we are continuing R&D on completely new types of raw materials," he continued.
"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, in line with our previous announcement."
A particular strength of Neste Oil's NExBTL technology is that it is capable of processing a very wide variety of different bio-based raw materials - such as vegetable oils, waste animal fat, and by-products from vegetable oil production - into renewable diesel, the company says.
All the raw materials used result in premium-quality fuel, Neste Oil said.
