Lignocellulose biorefineries

In a lignocellulosic biorefinery, biomass in the form of annual and perennial grasses, agricultural residues (e.g., straw, bagasse, husks and shells, corn cobs), wood and woody biomass is converted into a series of products. ifeu has been working on the sustainability assessment of lignocellulosic biorefineries since the late 1990s, before the concept of second generation biofuels even existed.

ifeu assesses the development of lignocellulosic biorefineries from the experimental stages to large-scale plants. Ifeu’s expertise helps to optimise the process development from a sustainability perspective, and shows both the disadvantages and risks along with the advantages and opportunities associated with the different concepts.

Selected projects involving ifeu include UNRAVEL, BIOCORE, SUPRABIO and BIOLYFE, in which various forms of biomass were converted into a range of different products.
