NNFCC was commissioned by the Lignocellulosic Biorefinery Network (LBNet) to survey the potential availability of existing domestic lignocellulosic non-food crop feedstock wastes and residues to support the development of UK biorefineries. The objective was to assess the current availability of domestic crop and forest residues; dedicated biomass crops; green waste and waste from the paper industry. Current competing uses for these materials were identified and the potential to expand the resource examined. Impacts of regional and temporal variability were considered and data on costs and composition were collated.
