The Horizon 2020 ButaNexT project aims to develop a highly efficient production process to convert sustainable 2nd generation feedstocks to biobutanol. The ButaNexT consortium is led by Green Biologics, with partners from Belgium, the Netherlands, Spain and the UK. The consortium have tested, validated and optimised, at lab and pilot scale, the supply chain to produce lower-cost biobutanol from lignocellulosic biomass and waste.
The team have worked to optimise each stage of the biobutanol production value chain: biomass pre-treatment, fermentation, downstream processing and blending. A pilot plant at 100L scale has been constructed, integrating all elements of the process together. Engine tests of biobutanol blended with gasoline, diesel, biodiesel and ethanol have been carried out.
E4tech has carried out a feedstock assessment, analysing the availability of straw, municipal solid waste, Miscanthus and woody residues across the EU; and assessed the greenhouse gas, techno-economic and social impacts of the biobutanol production process.
