  • Publication number: 20150048008
    Abstract: The invention relates to a waste treatment method in which waste is subjected to a first screening process (4). The fraction of waste passing through the screening is subjected to a pre-fermentation treatment in a rotating tube (1) and the material leaving the pre-fermentation treatment tube is subjected to mixing in a mixing hopper, and, subsequently, to a methanisation treatment in a digester (2). The organic materials are separated from the undesirable products in the material leaving the pre-fermentation treatment tube before it enters the digester. The digester (2) is horizontal and mechanically stirred, and a fraction of the digestate leaving the digester is recirculated at least in the mixing hopper, the recirculation rate being sufficiently high to ensure complete mixing.

  • Patent number: 7905356
    Abstract: A method for separation of heterogeneous products included in household waste (HW) comprises separating the products in a fractionation vessel containing a liquid. The waste includes components, of which at least some are capable of floating in the liquid. The components are exposed to a first essentially horizontal force (P1) in a first direction (D1) enforced by a flow of the liquid in the fractionation vessel and to a second essentially horizontal force (P2) in a second direction (D2), which is substantially different from the first direction (D1). The combined impact of the forces (P1; P2) on the components spreads the components and leads them to at least two collection areas. Products of varying buoyancy may thus be treated separately.

  • Patent number: RE42969
    Abstract: A portable trommel has a chassis, including support wheels at one end thereof for movement of the trommel. A trommel is rotatably mounted on the chassis and has an input and an output end. A hopper and an input conveyor, for supplying material to be screened to the input end of the trommel, are mounted on the chassis adjacent the input end of the trommel. An output or fines conveyor, for collecting material passing through the trommel screen, is mounted on the chassis, below the trommel. A stockpiling conveyor is mounted on the chassis and has a lower end adapted to receive screened material from the fines conveyor and an upper end for discharging screened material to form a stockpile. The stockpiling conveyor can be in two parts, which can be folded into a retracted position for storage and transportation, and further can be mounted for rotation about a vertical axis to enable an arcuate storage pile to be formed.
