  • Patent number: 9040289
    Abstract: A composting system is provided that uses gravity and natural thermal convection to yield a compact, modular, plug-flow compost reactor requiring minimal aeration and agitation energy. The compost reaction takes place in a self-supporting containment unit which is mounted at an angle with respect to its supporting base pad such that minimal external energy is required to mix and transport the composting material during its residence time within the container. The system uses natural convection to supplement external energy in the introduction of air into and through the material. Furthermore, the configuration of the containment unit and its supporting structures allow rapid deployment of compost facilities with minimal permanent civil work and minimal space requirements in a manner that enables subsequent relocation of the equipment.

    Abstract: An hydrolysis stage of an anaerobic digestion (AD) process includes supercritical treatment in a reactor (R1). The treatment may use sub-stoichiometric oxygen so that there is not full oxidation. Effluent from the supercritical treatment may be used to pre-heat the organic matter in-feed to the supercritical treatment. There may be a second supercritical treatment in a second reactor (R2). This may have full stoichiometric oxygen, to oxidise the solids from the first reactor (R1) effluent. Furthermore, it provides heat for pre-heating its own in-feed and also that for the first reactor (R1). The output from the hydrolysis may be only clarified liquid, leading to particularly efficient downstream AD processes. The second supercritical treatment rector may oxidise also fed-back solids from the final stage of the AD.

  • Patent number: 8685716
    Abstract: A composting apparatus and method is described. The apparatus comprises a cylindrical drum which is horizontally rotatably supported. A hopper is disposed at a feed end of the drum for receiving organic waste material in soft or hard form. A material shredding mechanism and a grinding mechanism are rotatably secured in the hopper and driven in counter-rotation for shredding and grinding the organic waste material and feeding it into an inlet opening of the drum. A series of material mixing and conveying vane assemblies are secured spaced-apart inside the drum and define sub-composting compartments therebetween. The material mixing and conveying vane assemblies have a plurality of vanes secured in spaced-apart relationship and project interiorly towards a central longitudinal axis of the drum and are oriented at a common angle to mix, further shred and displace shredded and ground material from the inlet opening towards the rear discharge end of the drum.

  • Patent number: 8637304
    Abstract: An economical method for recovering nitrogen from liquid waste using autotrophic organisms and minimal energy inputs and without chemical additives. Solids are separated from anaerobically digested liquid waste. The resulting translucent liquid is introduced to a culture of autotrophic microorganisms in the presence of natural or artificial light, thereby accumulating biomass and producing a liquid effluent with elevated pH. The elevated-pH, liquid effluent is heated and stripped of ammonia, thereby producing a water vapor and stripped ammonia gas stream. The water vapor ammonia gas stream is condensed to form a liquid/ammonia condensate. The autotrophic microorganisms are advantageously cultivated in a photobioreactor comprising a plurality of axially spaced-apart, growth plates mounted for rotation to a shaft. The pH of the culture is adjustable within a preferred range of 8.0 to 10.5 by adjusting the light intensity and rotational speed.

  • Publication number: 20140024108
    Abstract: An apparatus for production of a biogas by anaerobic digestion of organic material, the apparatus comprising: a digester chamber defining: a gas generating zone and a gas collecting zone. A biogas outlet is defined in the gas collecting zone, and one or more nozzles is/are arranged to spray a gas cooling liquid into the gas accommodated in the gas collecting zone so as to cool the gas. A collecting member is arranged in the gas collecting zone to collect the gas cooling liquid when sprayed from the one or more nozzles towards the collecting member so as to prevent the gas cooling liquid from entering the organic material. The collecting member is arranged to cause the collected gas cooling liquid to flow into a liquid based safety valve.
