Definitions

  • the present invention relates to a method for recycling the organic fraction of municipal solid waste and the like.
  • the source of the organic fraction is municipal solid waste derived from separate collection or sorted collection.
  • the produced amount of liquid fraction owing to its intrinsic characteristics, is the source of unpleasant odors, considerable processing and/or disposal costs, etcetera.
  • the aim of the present invention is to provide a dense organic liquid which is of excellent quality and is separate from the remaining fibrous part.
  • a consequent object is to provide such an organic liquid through simple and safe operations.
  • Another object is to provide sterilization of the residual products.
  • a further object is to provide a low-cost apparatus for sorting the resulting product.
  • a still further object is to increase disposal volumes for an equal fermentation plant.
  • Another object is to use insufficiently sorted fractions with good process results.
  • Another object is to expand the categories of waste that can be processed by means of a fermentation-based recovery process.
  • Another object is to obtain a higher quality and a larger amount of biogas.
  • Another object is a possible increase in the supply load, with a consequent increase in the specific potential of fermentation plants.
  • a method for recycling a pre-screened organic fraction of municipal solid waste and the like derived from separate or sorted collections characterized in that it comprises the steps of: shredding the pre-screened organic fraction, breaking up the cell membrane of the organic fraction; crushing the shredded organic fraction in order to separate a liquid part from a first solid part; subjecting to an anaerobic process said liquid part in order to obtain a second solid part and biogas.
  • Figure 1 is a block diagram of the layout of a method according to the invention.
  • FIG. 2 is another more detailed block diagram of an operating step of the method of Figure 1. Way of carrying out the Invention
  • the method comprises a first step 10 for opening bags, since the material arrives loose and contained in bags which must be opened in order to allow the discharge of the organic material.
  • the material is then subjected to a screening process 11, which consists in cleaning by separating out plastics, various containers, metals, etcetera.
  • the organic material is then shredded, step 12, undergoing comminution and breaking the plant cell walls so as to facilitate the release of the cell sap, and is then crushed, step 13.
  • step 13 separation occurs between a liquid-dense part 14 on one side and a woody-fibrous solid part 15, with the remaining impurities, on the other.
  • steps 12 and 13 are provided by means of various types of apparatus, such as variable-pitch screw feeders, press heads, pressing systems using shock waves produced by explosion or air or gas pressure, accompanied by a series of perforated grids or membranes which allow drainage of the dense liquid 14 and retain the solid fraction or fiber 15 and/or the impurities inside the pressure region.
  • the resulting liquid part 14 has a light brown color, a density approximately equal to that of oil, a pungent acrid odor, a percentage of total solids on the dry substance of 7-15%, a percentage of volatile solids on the dry substance of 70-75%, a C/N (carbon/nitrogen) ratio of 1/12 ⁇ 2%, a percentage of impurity of less than 0.5% and a pH of 4-5.
  • the steps 10, 11, 12 and 13 sort the organic fraction of municipal solid waste and the like, achieving a degree of cleaning of the material with particle size and uniformity adapted for feeding anaerobic reactors 20, opening a new frontier in the use of this biological process in the field of recovery and reuse.
  • the material to be fermented In order to achieve good fermentation and thus maximize the yield in biogas production, the material to be fermented must in fact be as much as possible dispersed and solubilized in a liquid, so as to increase the efficiency of the breakdown of carbon compounds on the part of methane- generating bacteria.
  • the steps 10, 11, 12 and 13 provide an extremely fine dispersion of the liquid.
  • the organic liquid 14 is used for a subsequent step which is constituted by an anaerobic process 16 for producing biogas 21, while the fibrous part 15 is sent to the aerobic process 28.
  • the liquid part 14 is thus destined for the anaerobic fermentation process 16, collecting into a discharge region 17 and, by means of a pump 18, into a homogenization tank 19, from which it then enters an anaerobic reactor 20.
  • Biogas 21 exits from the reactor 20 and can be advantageously utilized to obtain heat 22 and/or electric power 23.
  • a spent substance second solid part
  • sludge 25 and a supernatant liquid part 26, destined for biological conditioning 27, are obtained by means of a belt press 24 which is per se known.
  • the extraction of the liquids allows to accelerate and optimize the fermentation process and to select only the part that is useful for anaerobic fermentation, at the same time releasing a residue which is sanitized and is to be used, in the composting process, as organic material with a high nitrogen content (5-6%) in a mixture with the woody-fibrous part in order to obtain a biological organic fertilizer.
  • the system is provided as an alternative to current waste disposal systems, demonstrating that it integrates perfectly in the recovery of biomasses as a renewable and alternative energy source.
  • the materials and the dimensions may be any according to requirements.

Abstract

L'invention concerne un procédé de recyclage d'une fraction organique de déchets municipaux solides provenant de déchets séparés ou triés, consistant à broyer (12) la fraction organique, à casser la membrane cellulaire de la fraction organique, à concasser (13) la fraction organique broyée afin de séparer une partie liquide (14) d'une première partie solide (15), et à soumettre la partie liquide (14) à un processus anaérobie afin d'obtenir une deuxième partie solide (25) et du biogaz (21).
