A process which comprises a) converting lignocellulosic biomass into fuel and producing an aqueous waste stream, which aqueous waste stream comprises dissolved organic materials and dissolved sulfur-containing compounds, and which aqueous waste stream has a sulfur content of more than 400 parts per million by weight, relative to the weight of the aqueous waste stream; b) treating the aqueous waste stream, wherein the treating comprises anaerobic digestion of a mixture comprising the aqueous waste stream, as a first aqueous feed, and a second aqueous feed, wherein - the second aqueous feed may or may not comprise dissolved sulfur-containing compounds and has a sulfur content, if any, of less than 400 parts per million by weight, relative to the weight of the second aqueous feed, and - the mixture has a sulfur content of at most 400 parts per million by weight, relative to the weight of the mixture. |
