Definitions

  • the present invention relates to a process for handling waste material.
  • waste management methods consist in the use of refuse dumps and incinerators.
  • Incinerators base their operation on waste incineration; the latest models exploit the combustion thus obtained and recuperate a little electricity and heat but have the problem of managing toxic-harmful emissions, particulates and dioxins.
  • MCT mechanical-biological treatment plants
  • MBT plants make use of the cold treatment technology of unsorted wastes and/or which are left over from pre-sorted collection, and which exploits the combination of mechanical and biological processes such as anaerobic digestion and composting.
  • the stabilised organic fraction stands out from the so-called "compost” inasmuch as it is produced starting with unsorted wastes, while compost is only made starting from pre-sorted organic material.
  • the stabilised organic fraction is not used as agricultural fertilizer (as in the case of compost) but, being characterised by fermentability reduced by up to 90%, it is particularly suitable for various applications aimed at environment and landscape rehabilitation and the daily covering of refuse dumps (instead of earth) without having emissions of natural gas which, if released into the atmosphere, is a greenhouse gas about 21 times more harmful than carbon dioxide.
  • MBT plants are designed to feed incinerators with the produced fuel derived from wastes; in some cases even, the MBT plants are simply used to grind the wastes without any real benefit either for recycling or for incineration.
  • an MBT plant which produces stabilised organic fraction from wastes first of all contemplates sieving with separation of a rough and not very fermentable part, consisting e.g. of paper, cardboard, plastic, metals, glass, etc., which can in part be recycled and in part sent to make up the fuel derived from wastes, and of a part rich in organic and highly-fermentable substances, which once stabilised becomes stabilised organic fraction.
  • the biochemically inert fraction is sent for disposal/recycling, while the organic substance undergoes the abatement of the organic content and biological treatment suitable for speeding up fermentation and therefore producing end material with low fermentability.
  • Thor and Refolo consist in the total refining of the various incoming waste fractions by means of a mechanical-chemical treatment.
  • the Thor process consists in the micronisation of wastes, i.e., grinding down to a size below about 100 ⁇ exploiting the principle of mechanical-chemical activation, i.e., a strong mechanical friction action which determines the delamination of the organic, polymer or textile materials, the molecular cracking of the chlorine in chlorinated plastics and the separation of metals which are trapped as pigments.
  • the mechanical-chemical reactor contains grinding masses speeded up by an eccentric movement and thrown at high speed against the material which undergoes a compression and cutting action.
  • This process has a first liquid biological treatment which performs a first separation of the materials split up according to specific weight by means of a wet treatment in a large tank with water.
  • the heavy material is then sent for recovery, recycling or to the refuse dump, while the lightweight material and dissolved organic material are sent to complex washing, filtering and sorting processes and to bioreactors to produce fertilizer, water and biogas.
  • the stabilised organic fraction contains combustible fractions such as plastic materials, paper, cardboard, fabrics which, besides being subtracted from the fuel derived from wastes fraction, reduce the quality of the stabilised organic fraction to the extent of preventing this being used again for environmental recovery or the like, thereby increasing the volumes sent to the refuse dump, with consequent reduction in the duration of same.
  • the main aim of the present invention is to provide a process for handling waste material which may be efficient and cheap at the same time in order to obtain a better separation of the different heterogeneous components of the mix of treated materials.
  • Another object of the present invention is to provide a process for handling waste material which allows overcoming the mentioned drawbacks of the state of the art within the ambit of a simple, rational, easy and effective to use as well as low cost solution.
  • Figure 1 is a layout view of a part of the plant for the implementation of the process according to the invention
  • Figure 2 is a layout view of another part of the plant for the implementation of the process according to the invention.
  • the present invention aims at the handling of a waste material M meant as any material or product deriving from household wastes, industrial wastes, agricultural wastes, etc.
  • waste material M therefore, must not be considered only as unsorted solid household residue, but also as any product deriving from the treatment of wastes, such as, e.g., stabilised organic fraction, fuel derived from wastes and the secondary raw materials deriving from pre-sorted collection or industrial process wastes and scraps.
  • the waste material M is a substantially heterogeneous compound mainly composed of the following three families of components:
  • the first fraction I is generally composed of polymers, paper, cardboard, wood, etc., and is the fraction whose components have greater lower combustion heat and the most suitable for the production of fuel derived from wastes;
  • the second fraction II is generally composed of aggregates, glass, ceramic, minerals, clays, organic materials, etc., and is the fraction which constitutes less environmental problems as regards re-use in the field of environmental restoration or soil amendment or the like;
  • the third fraction Ilia, Illb is generally composed of metals, both ferrous metals Ilia and non-ferrous metals Illb, the recovery of which is particularly desirable, both because of the intrinsic economic value of these materials and as regards the environmental issues tied to discarding in the environment.
  • the present invention is essentially based on the control and management of the toughness of the different fractions I, II, Ilia, Illb making up the waste material M.
  • any material when subjected to stress, is consequentially deformed and absorbs the applied energy.
  • the stored up elastic energy can produce the formation of new surfaces, called fracture surfaces, which can end up by determining their breakage (fragile behaviour).
  • globally indicated by 1 is a plant for the embodiment of the process according to the embodiment.
  • the plant 1 comprises a collection and feed line 2 of the waste material M. Downstream of the collection and feed line 2 a separation line 3 is installed for picking up the third fraction Ilia, Illb from the waste material M.
  • the separation line 3 is of the type in itself known and is suitable for making it possible to separate both the ferrous metals Ilia and the non-ferrous metals Illb from the waste material M. c
  • the separated third fraction Ilia, Illb can therefore be sent to a recovery process in smelting-furnaces, steelworks, etc.
  • the efficiency of the separation line 3 permits picking up most of the third fraction Ilia, Illb from the waste material M, but it is possible that a part of the third fraction Ilia, Illb remain unseparated.
  • a mill 4 with loose grinding bodies 6 is installed for grinding the waste material M.
  • the mill 4 is preferably selected from the list comprising: a ball mill, a cylinder mill, a bar mill, a pebble mill and an attritor mill.
  • the mill 4 comprises a rotating grinding chamber 5, having a preferably cylindrical shape with horizontal axis R.
  • the mill 4 turns around its horizontal axis R.
  • the mill 4 has an inlet mouth 7, for introducing the waste material M coming from the separation line 3, which is served by a hopper 8 and is located at an axial extremity of the grinding chamber 5.
  • the mill 4 is designed to operate continuously, with the waste material M being loaded through the inlet mouth 7 and coming out through the outlet mouth 9.
  • control of the process parameters of the mill 4 including the applied energy, the running temperatures and the grinding times, it is possible to obtain the grinding and particle size reduction of some fractions of the incoming material and not of others.
  • the mill 4 is loaded with a waste material M having a first fraction I and a second fraction II of substantially rough particle size, at the outlet from the mill 4 the first fraction I will have a substantially unchanged particle size, while the particle size of the second fraction II will be substantially fine.
  • the mill 4 is crossed by a gaseous flow, e.g., a flow of air extending from the inlet mouth 7 to the outlet mouth 9, for the extraction of the first fraction I and of the second fraction II when their bulk density is substantially equal to or lower than a pre-set bulk density.
  • a gaseous flow e.g., a flow of air extending from the inlet mouth 7 to the outlet mouth 9, for the extraction of the first fraction I and of the second fraction II when their bulk density is substantially equal to or lower than a pre-set bulk density.
  • the lighter materials having a lower bulk density, therefore tend to be quickly extracted from the mill 4.
  • any hefty body which is ground down undergoes a physical change and switches from a compact configuration with high bulk density to a broken-up configuration with lower bulk density, with an increase in external surfaces, formed by breakage, and in total overall dimensions.
  • the first fraction I has a bulk density substantially equal to or lower than the order of magnitude of the pre-set bulk density (e.g., below 0.6 g/cm 3 ) and such as to allow the gaseous flow to extract the first fraction I in a fairly short times.
  • the second fraction II has a bulk density substantially higher than the pre-set bulk density (e.g., above 1 g/cm 3 ) and such as to allow the gaseous flow to extract the second fraction II only after that, because of grinding, the bulk density of the second fraction II has lowered (e.g., to 0.6 g/cm 3 ).
  • the plastic and the glass have a different specific weight, lighter the plastic and heavier the glass, which, dimensions being equal, means a much different matter density between the two materials, lower for the plastic and higher for the glass.
  • the piece of plastic is intended to remain in the mill only a short time, inasmuch as quickly removed by the air flow and, by virtue of its ductility, is able to withstand the knocks produced by the loose grinding bodies 6, which appear substantially ineffective.
  • the piece of glass tends to remain in the mill longer and undergoes the knocks produced by the loose grinding bodies 6 which, by virtue of its fragility, result in its being broken up into smaller pieces until these too can be conveyed towards the outlet by means of the air flow.
  • the mill 4 can also be advantageously equipped with a compressed-gas introduction system which, on expanding, lowers the temperature in the grinding chamber 5.
  • the mill 4 also comprises an overflowing mouth 10 for the outflow of the loose grinding bodies 6 and of any third fraction Ilia, Illb introduced into the mill 4.
  • the load of the mill 4, comprising the waste material M to be treated and the loose grinding bodies 6, is kept in excess with respect to the working capacity of the mill 4 so as to allow the exit of the third fraction Ilia, Illb through the overflowing mouth 10.
  • the overflowing mouth 10 and the outlet mouth 9 are coinciding, but alternative embodiments cannot be ruled out wherein these are distinct and separate, one for the exit of the first fraction I and of the second fraction II by effect of the air flow and one for the overflow of the loose grinding bodies 6 and of the third fraction Ilia, Illb.
  • the flow of air which crosses the mill 4 is produced by an aspirator 1 1 connected to the outlet mouth 9 by means of a suction duct 12a, 12b.
  • a cyclone 13 Along the suction duct 12a, 12b are arranged in succession a cyclone 13, a first separation device 14 and a second separation device 15.
  • the cyclone 13 is 1 connected to the outlet mouth 9/overflowing mouth 10 and is suitable for receiving both the first fraction I and the second fraction II, conveyed by the air flow, and the third fraction Ilia, Illb and the loose grinding bodies 6 which have overflowed out.
  • the purpose of the cyclone 13 is to treat the third fraction Ilia, Illb and the loose grinding bodies 6, separating them from the air flow and collecting them up by gravity on a recirculation line 16 which again sends them to the collection and feed line 2, allowing in particular the collection of the loose grinding bodies 6 which have overflowed and their reintroduction into the mill 4.
  • the air flow coming out of the cyclone 13 reaches the first separation device 14, which allows splitting up by particle size the first fraction I, not ground and rough, from the second fraction II, ground and fine.
