Short summary

We develop systems for cropping, processing and characterisation of biomass from grass intercropped with legumes for different purposes.

The project focus on harvest of green biomass that has been fertilized with biosolids. Fractionation of the biomass both with field based equipment and in a lab pilot will be evaluated as feedstock for both energy (biogas and bioethanol) and products (for example fibre products, absorption material, insulation material, fodder and extraction of specialized chemicals). The most promising systems are evaluated with respect to economy and environmental impact.

GrassRefine is a completed project. It was a collaboration between the former Department for Agricultural Research in Northern Sweden and the Department for Forest Biomaterial and Technology at the Swedish University of Agricultural Sciences.
