Biorefineries processes and integration
Assessing the Environmental Sustainability of an Innovative Green Biorefinery to Reduce Soybean Dependency
Short Introductive summary
The rise of green biorefineries allows new avenues of animal proteinaceous feed production using green biomass to produce leaf protein concentrate (LPC) and utilize side-stream products, such as brown juice and press cake, for feed-quality products and bioenergy. This study evaluated the combination of grass-clover biorefinery and the power-to-gas concept for its environmental sustainability through a consequential life cycle assessment (CLCA). The findings indicate that combining a green biorefinery with power-to-gas can increase the environmental benefits. Such an integration resulted in an avoided impact of -1556 kg CO2-eq/t of protein concentrate. Such an integration resulted in an avoided impact of -1556 kg CO2-eq/t of protein concentrate. The avoided impacts of climate change could be higher within the first 20 years due to a higher carbon sequestration rate. However, even after 20 years when a new carbon balance in the soil is reached, the environmental gain is big enough to encourage the production and use of organic grass-clover protein concentrate.
