Definitions

  • the present invention is concerned with a recycling process. More particularly, the present invention is concerned with an improved recycling process for unsorted waste, for example waste generated by the retail industry. The present invention is also concerned with a method of manufacturing three dimensional objects from unsorted waste, for example waste generated by the retail industry.
  • Waste generated by the retail industry includes items which have been manufactured from polymeric materials, glass, synthetic fabrics, natural fabrics (such as cotton and leather), as well as metals.
  • the items include packaging (for example carrier bags, boxes and other containers), discarded stock (such as clothes, bags and shoes) and discarded merchandising items or fixtures and fittings from a shop (for example display boards).
  • Incineration is an alternative process for unsorted waste.
  • the waste is burned and converted into ash, flue gas and heat.
  • Gaseous and particulate pollutants must be removed from the flue gas before the flue gas is released into the environment.
  • Some systems are set up to generate electric power from the generated heat.
  • Recycling is a popular alternative to burying or incinerating waste. Recycling processes generally aim to save material, minimise energy usage and reduce the pollution of soil, water or air. Waste that is to be recycled is typically sorted and cleaned prior to reprocessing into new materials and products. The sorting and cleaning of waste is either carried out manually or with the use of automated systems. Each of these sorting methods increases the cost and reduces the economic efficiency of recycling as an approach to waste processing.
  • a method of recycling waste wherein the method of recycling waste includes mechanically processing the waste and mixing the mechanically processed waste with a binding agent.
  • the waste is unsorted waste.
  • unsorted waste we mean waste that includes a variety of unsorted waste items, including different products and packaging made from a range of materials including glass, plastic, metal and fibrous materials.
  • the range of materials may include a mixture of natural and man-made, or synthetic, materials.
  • the step of mechanically processing the waste may include using more than one mechanical process, thereby using more than one machine or piece of equipment.
  • the step of mechanically processing the waste may, for example, include using a first mechanical process and a second mechanical process, wherein the second mechanical process is different to the first mechanical process.
  • the first mechanical process may, for example, be a shredding process.
  • the shredding process may be carried out using an industrial shredder or grinder.
  • the first mechanical process may result in the formation of a granular material having a first particle size in the range of 0.5 millimetres to 20 millimetres.
  • the second mechanical process may, for example, be a crushing or pulverising process.
  • the crushing or pulverising process may be carried out using a hammer mill.
  • the second mechanical process may result in the formation of a powder having a second particle size in the range of 0.005 millimetres to 0.4 millimetres.
  • the step of mechanical processing the waste can advantageously be optimised to form a fine, sand like, material which can be used as an alternative to natural sand. This offers a further environmental benefit as natural sand is a non-renewable resource.
  • binding agent we mean a component or agent which enables the granular and powder materials which are formed from the waste (the mechanically processed waste) to be bound or adhered together to form a solid material.
  • the mixture of the mechanically processed waste and the binding agent may include at least 40% binding agent.
  • the mixture of the mechanically processed waste and the binding agent includes at least 50 wt% binding agent and/or less than 75 wt% binding agent.
  • the binding agent may include an organic binding agent.
  • the binding agent may include an inorganic binding agent.
  • the binding agent may include a first component and a second component.
  • the binding agent may include at least 65 wt% of the first component and/or less than 85 wt% of the first component.
  • the first component may include calcium, for example calcium carbonate.
  • the second component may include calcium, for example calcium sulphate hemihydrate.
  • the mixture of the mechanically processed waste and the binding agent may be further mixed with a liquid to form a moulding material.
  • the liquid may include water, for example waste water.
  • the waste water may preferably be non-sewage waste water, such as surface water (i.e. collected rain water) or grey water (water that originates from non-toilet or food fixtures).
  • the method of recycling waste may further include adding a pigment to the moulding material.
  • the pigment may be added to the moulding material as a solid material (for example in granule or powder form) or as a liquid.
  • the method of recycling waste may further include pouring the moulding material into a mould.
  • the method may further include curing the moulding material in the mould to form a three dimensional object.
  • Figure 1 is a flow chart a method of recycling waste according to the present invention
  • Figure 2a is a schematic side view of a mould for casting a three dimensional object
  • Figure 2b is a schematic side view of the mould of Figure 2a into which moulding material has been poured.
  • Figure 3c is a schematic side view of the mould of Figure 2b with the moulded object removed.
  • waste 22 is collected into a suitable container (not shown).
  • the waste 22 includes a variety of unsorted waste items, including different products and packaging made from a range of materials including glass, plastic, metal and fibrous materials.
  • the range of materials may include a mixture of natural and man-made, or synthetic, materials.
  • the waste 22 is broken down into granular material 24 by a shredding process.
  • the shredding process may be carried out using any suitable machine such as an industrial shredder or grinder.
  • the resulting granular material 24 has an average particle size in the range of 0.5 millimetres to 20 millimetres.
  • the granular material 24 is crushed or pulverised into a fine powder, or sand-like, material 26.
  • the pulverising step may be carried out using any suitable machine such as a hammer mill.
  • the resulting powder 26 has an average particle size in the range of 0.005 millimetres to 0.4 millimetres.
  • the powder 26 is mixed with a binding agent 28, for example an inorganic binding agent such as an inorganic binding agent including calcium.
  • the inorganic binding agent including calcium may include a mixture of one or more of calcium carbonate, calcium sulphate (e.g. calcium sulphate hemihydrate), calcium oxide and calcium hydroxide.
  • the inorganic binding agent including calcium may be provided in the form of limestone, lime, cement, plaster of Paris or gypsum.
  • the resulting mixture of the powder 26 and the binding agent 28 includes 25 to 75 wt% of the binding agent.
  • the binding agent 28 may be a mixture of two components.
  • One or both of the two components may be an inorganic binding element, such as an inorganic binding element including calcium.
  • the first component may, for example, be calcium carbonate.
  • the second component may be, for example, calcium sulphate hemihydrate.
  • the binding agent 28 may include 65 wt% to 85 wt% of the first component.
