Recent research and development in green biorefining aim to produce a sustainable protein feed from domestically grown grasses and legumes, that can substitute imported soymeal in animal feeds. A byproduct of this process is a high fibre press-cake fraction, that will require valorisation. Integration of pyrolysis of the press-cake into the herbaceous protein production is an innovative approach to increase the economic and environmental viability of the biorefinery. This work investigated the production of biochar for animal feed from the fibre press-cake via slow pyrolysis in a laboratory-scale batch reactor.
