The opportunity exploited in SYLFEED is to look at a more sustainable raw material source to produce protein for feed: Lignocellulose (non-food biomass from wood). The project combines lab trials for selection of strains for conversion of lignocellulose to sugar and protein, fish feed trials, and economic and environmental modelling. Life cycle assessment is used to understand the environmental performance of the new technology. 

SYLFEED consists of several work packages with different scientific methods from laboratory methods for development of biorefinery processes to animal testing to desktop studies of economic and environmental viability. The LCA method used to assess the environmental performance of the technology is partly based on methods recommended during the work with Environmental Footprints (EF) at the EU level.
