To become a bioeconomy for real – how do we solve issues about sustainable protein feed and renewable energy?
In order to increase substantially production of biogas that replaces fossil fuels we need vast amounts of biomass that agriculture can supply without affecting current food and feed production. But instead of digesting the green biomass from ley crops, sugar beet tops and other residues directly, Green2Feed aims to extract plant protein that can be used as feed for e.g. pigs and cows. The green biomass is separated in several fractions that are suitable as protein-rich animal feed while other fractions serve as feedstock for biogas production. This combined production enables replacement of fossil fuels and e.g. imported soya protein, with low control of sustainability. The ecological footprint of the Green2Feed process is expected to be much lower than that of the replaced products, as plant nutrients and organic carbon are returned to arable land in the form of digestate
