Renewable diesel maker Neste Oil says it will move away from turning microbes into the green fuel and concentrate on other feedstocks, such as forestry and agricultural waste. This company news release says the Finland-based Neste Oil wants to increase the number of renewable inputs used for the renewable diesel.
“Our microbial oil pilot plant at Porvoo has demonstrated that we have the technical capability for producing microbial oil,” says Neste Oil’s Senior Vice President, Technology, Lars Peter Lindfors. “Seen in terms of sustainability, using waste and sidestreams generated by agriculture and forestry as well as industry has a very important role to play in the future, and we have successfully used straw, for example, to produce microbial oil. Two years of in-depth microbial oil research at the pilot plant has generated a lot of valuable know-how and extended our patent portfolio, and we will be able to use the results of this work in other research projects.
“The time is not yet ripe for a commercial-scale microbial oil plant, however. Lignocellulose material is not a financially competitive industrial feedstock for producing renewable diesel using the microbial oil process at the moment. We will continue researching agricultural and forestry waste and residues, and believe that lignocellulose inputs will play an important role in future renewable applications,” says Lindfors.
The release does not say how this could affect a recent deal with U.S. algae producer Renewable Algae Energy (RAE) to supply algae oil as an alternative feedstock for Neste Oil’s NEXBTL renewable diesel for the future.
