Straw as a raw material of renewable fuel
Microbial oil technology developed by Neste Oil enables straw to be used as a feedstock for producing renewable NExBTL diesel. Trials have been carried out using straw to produce microbial oil production at Neste Oil's pilot plant at Porvoo and the results have been promising.
Large quantities of waste straw are produced as agricultural residue in Finland and elsewhere, and only a small proportion of this is currently used. The joint Neste Oil–Raisioagro project is looking at whether a logistically effective and efficient, large-scale straw harvesting chain could be created in Finland. The storability of straw for use as an industrial input year-round is also being investigated. Developments in technology and the growing size of today's farms, for example, together with the shift to more specialized farming methods, have improved the potential for making greater use of straw. The goal of the research project is to investigate the practical questions involved in collecting straw under different conditions, how efficiently it can be done, and various quality-related issues. The level of interest among farmers and contractors in making greater use of straw will also be studied.
