摘要:
A method for processing mixed waste comprising the steps of a) separating the waste into at least two parts; a mainly food waste (fines) and (ii) mainly paper and other recyclable material (overs), and b) pulping the overs and washing the overs to obtain a cellulose rich biomass. The over pulping step may employ hydro-mechanical pulping. Optionally, the fines may also be processed to obtain a cellulose rich biomass, preferably by thermo-mechanical pulping. The waste may be municipal solid waste from households and commercial establishments. The separation step is ideally performed using a trommel or screen. Ideally the separated fines have a diameter of less than 200mm. Preferably any plastics or metal materials are removed from the pulped waste before the washing step. Textiles may be removed prior to pulping the overs. A cellulose rich biomass comprising 6% ash and a glucan:xylan ratio of between 5 to 8:1 is also disclosed.
