Abstract: The present invention provides a method for non-catalytic delignification of biomass, without externally added catalyst, with a mixed solvent of oxygenated organic solvent and water in the presence of an oxidant, at moderate temperature and pressure. Further, the separation of delignified cellulose from liquid mixture is carried out at around equivalent process conditions. Low modified kappa number delignified cellulose is obtained after separation of a liquid mixture containing a mixed solvent, hemicelluloses, lignin and traces of miscellaneous compounds. Furthermore, the method has lower chemical consumption in the downstream process, ease of operation and robustness.

Abstract: This specification describes a system and process for treating waste, for example municipal solid waste (MSW) or post-recycling municipal solid waste. The system includes a press and a pulper. The press is adapted to provide a wet fraction of the waste suitable for anaerobic digestion and rejects. The pulper is adapted to receive the rejects and produce pulp. The pulper may be, for example, a drum pulper. In the process, waste is separated into a press into an organic fraction and rejects. The organic fraction is treated by way of anaerobic digestion. The rejects are separated, optionally in a drum pulper, to produce a fraction containing pulp. The pulp can be re-used to make paper or other products. In some case, 70% or more or 80% or more of MSW can be diverted from landfill.
