The goal of this project is to develop a web-based tool for small and medium-sized farms to be able to estimate potential renewable energy MWh and GHG reduction and costs for adding biodigestors to produce biogas for fuel and to reduce environmental impact from disposal of untreated liquid wastes.
In industrial chemistry, black liquor is the waste product from the kraft process when digesting pulpwood into paper pulp removing lignin, hemicelluloses and other extractives from the wood to free the cellulose fibers.The equivalent material in the sulfite process is usually called brown liquor, but the terms red liquor, thick liquor and sulfite liquor are also used.
