    摘要： In a system and process, sludge from a wastewater treatment plant is treated in a high solids digester, optionally a mechanically mixed wet digester. Sludge (i.e. digestate) from the anaerobic digester is thickened or dewatered. Part of the thickened or dewatered digestate is thermally hydrolysed. The hydrolysed digestate may be, or may be further treated to produce, Class A biosolids. The hydrolysed digestate can be dewatered producing a liquid fraction that is recycled to the digester. Another part of the thickened or dewatered digestate is returned to the digester. The return of thickened or dewatered digestate to the digester allows for a smaller tank to be used (compared to a system without a recycle of thickened or dewatered digestate) while maintaining the same solids residence time (SRT) and volatile solids reduction (VSR). In some examples, the hydraulic residence time (HRT) of the digester is 10 days or less.

    摘要： Organic waste is treated by pyrolysis or by anaerobic digestion followed by pyrolysis of the digestate. The pyrolysis is performed in two staged reactors. The second stage reactor treats char produced in the first stage. The temperature of the first stage reactor is preferably 450 degrees C. or less. The temperature of the second stage reactor is higher than the temperature of the first stage, for example by 50 degrees C. or more. Optionally, there may be a char cooler, a water sprayer, or both downstream of the char outlet of the second reactor. In an exemplary system, a digestate outlet is connected to the inlet of the first pyrolysis reactor. A pyrolysis liquid outlet of the first pyrolysis reactor is connected to the digester. Char produced in the second pyrolysis reactor may be used as a soil amendment.

    摘要： 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.

    摘要： Solid waste, for example source separated organics (SSO) or commercial and industrial (C&I) waste or both, are treated by first pressurizing the waste against a screen to produce a solids fraction and a liquid fraction. The liquid fraction can be treated in an anaerobic digester. The solids fraction is pulverized or milled, for example with a hammer mill, preferably after being diluted. The pulverized or milled waste is separated again to provide a second solids faction and a second liquid fraction. The liquid fraction can be treated in an anaerobic digester. The solids fraction is primarily inert and can be landfilled, preferably after being washed.

    摘要： A process and apparatus for the anaerobic digestion of organic wastes, preferably to also produce a useful biogas, is described. The waste may have a total solids (TS) concentration of 6% or less while a digester is operated at a higher solids concentration, for example with a feed TS concentration of 8-12%. One or more separation stages downstream of the digester separate active bacteria and undigested organics from the digestate, and return separated matter to the digester. Optionally, a feed thickening apparatus and step may be provided upstream of the digester. The upstream thickener and recycle from the downstream separation stages are operated such that the TS of the combined inputs to the digester is within a desired range.
