  • the processing devices 12 are of similar form, being as shown in Figure 4. Each comprises a somewhat rectangular container 26 with a rectangular lower portion 28 having a sidewall 30 and a lower somewhat funnel-shaped base 31. Container 26 also has a rectangular lid 32 with a roof 34, and a peripheral sidewall 36. The lid 32 is removable to enable downward access to the upwardly open lower portion 28.
  • a bed 38 of organic material in which earthworms 40 work is supported within lower portion 28 by a filter structure 42 of tray-like form, being upwardly open and having a rectangular sidewall and a base.
  • Filter structure 42 comprises two filters, a primary filter 44 and a secondary filter 46, each of tray-like form, the secondary filter 46 being nested within the primary filter 44.
  • the primary filter 44 may be formed for example of plastics netting, with a mesh size of the order of 1 mm, the secondary filter being formed of fine plastic mesh size of the order of 0.5 ⁇ m. As shown, both filters are rolled up at the ends of the bed to prevent processing of the material in bed 38 being conducted under anaerobic conditions.
  • a final filter 48 is formed as a rectangular structure having an outer peripheral frame 52 of annular form and having a plastic mesh extending across the frame and supported thereby.
  • the mesh may have a mesh size of the order of 0.5 mm.
  • the filter frame 52 rests on the ledge 45, with a rectangular frame portion 56 of the bed structure 42 resting on that.
  • the inner surface of the sidewall of the lower portion 28 of the container 26 has a peripheral groove 60, and an annular O-ring 66 is positioned in this and arranged to sealingly engage the outer periphery of the structure 42, to prevent worms escaping from the structure 42 from passing therebelow and to enter the funnel-shaped base 31.
  • the final filter 50 is likewise arranged so as to prevent worms that may escape from the base of the structure 42 from so- entering base 31.
  • lid 32 When lid 32 is in position on lower portion 28, a substantially sealed enclosure is formed around the bed 38.
  • the lower portion 28 may, alternatively or additionally be slidable on the frame portion 56 to enable it to be withdrawn from the remainder of processing device 12.
  • Water supply pipes 70 are arranged to supply water to the device 12.
  • the illustrated device 12 is shown as having an interior spray pipe 72 at the upper part thereof, which spray pipe communicates, via an opening in the lid portion 32 with a pipe 70 so that when water is supplied to the pipe 70, part of this enters the pipe 72 to be sprayed on the bed 38.
  • An air supply pipe 74 is likewise provided for supply of air to each of the devices 12.
  • Each pipe 74 communicates with an inlet pipe 76 of each device 12, which inlet pipe 76 passes through an opening in the lid 32 to supply air to an upper part of the closed chamber 35 defined by the lower portion 28 and lid 32.
  • a second branch pipe 78 associated with each device 12 passes through the respective sidewall 30, below the ledge 45, to supply air to the interior of the base 31.
  • An air outlet 80 is provided to exhaust air from the interior of lid 32 and chamber 35, at the upper part thereof.
  • the lowermost point of the base 31 of each device 12 communicates with a respective outlet pipe 84.
  • the outlet pipes 84 of each of the devices 12 are coupled to a common outlet (not shown) via respective one-way valves 86 which permit flow of liquid from the bases 31 through the pipes 84 to that outlet, but preclude backflow.
  • Figure 5 shows the arrangement of pipes 70, 72, 74, 76, and 84, viewed in plan.
  • the devices 12 are first placed in an open condition by upward lifting of the lid 32, whereafter worms and particulate organic or vegetable material, prepared in a way described later, are positioned in a layer to form the bed 38 within the filter structure 42.
  • this bed is arranged to be of thickness, or depth, of the order of 2 to 3 cm only.
  • the worms then consume the material and excrete liquid and solid castings.
  • the conditions within the device 12 may be arranged, in a manner described later, so that the amount of solid castings generated is relatively low and so that the liquid castings predominates. It is preferred however that the amount of solid castings generated is relatively higher, so that the solid castings predominate.
  • 60 to 65% by weight may comprise castings, with 35% being liquid.
  • the liquid castings passes through the filters 44, 46, thence passing downwardly through the final filter 48 to be collected in the base 31 and thence to flow outwardly through pipe 84 and valve 86 to the common liquid collection point.
  • water is supplied as required to the bed 38, and air likewise supplied within the device 12 above the bed, both for purposes of maintaining living conditions for the worms.
  • the air is temperature controlled so as to maintain a suitable temperature within the device 12 and within the bed 38.
  • a temperature sensor 90 is provided within the bed to enable appropriate control of the temperature of the air entering the chamber.
  • the humidity is controlled by varying the rate of inflow of water and/or air in accordance with detected humidity by a detector 92 positioned in the upper part of the device 12.
  • the provision of air from pipe 78 to the base 31 serves to pressurise the atmosphere in the chamber 35, and above the collected liquid castings, to assist in movement of the castings out through pipe 84.
  • earthworms prefer a temperature in the range 20 to 20 °C to 22° C, requiring in many instances that the air entering the chamber be refrigerated in summer and heated in winter. It has also been found to facilitate the process if the oxygen level of the entering air is increased above that normally prevailing.
  • the thickness of the upper part of the bed 38, comprising food material may be maintained at about 2 to 3 cm. That is to say, for example, food may be added periodically, such as at weekly intervals, to maintain the bed thickness in this range.
  • food may be added periodically, such as at weekly intervals, to maintain the bed thickness in this range.
  • the feed material used may comprise generally available waste organic material, such as vegetable matter.
  • the material be reduced to particulate form before use.
  • the collected liquid from the plant is generally useful as organic fertiliser.
  • Figure 2 illustrates processing steps at the plant 10 from the beginning of delivery of waste organic material at a transfer station 100 to final delivery at a delivery station 150.
  • the material is moved on a conveyor 102 to a hammer mill 104. While moving on the conveyor, the material is subjected to process steps 130, 132, 134, 136, respectively, of metal removal, heat treatment, plastics removal and removal of non-organic material.
  • the heat treatment may be carried out such as to heat the material to a temperature in the range 75°C to 95°C.
  • the removal of metal plastics and non-organic materials may be effected in known ways.
  • the material is reduced to particulate form, whereafter it passes through a cooling stage 106 and is then, at the step 108 shown, transported to the process room 18 and positioned within the beds 38.
  • the step 110 shown, of extracting liquid organic fertiliser is effected in the way described previously, via the outlet pipes 84 from the devices 12.
  • the removed material is then subjected to sterilisation, at step 112 shown, and then passed to store 114. It is then, at step 116 shown, packed or bottled and thence passed on a conveyor 118 to a conveyor transport 120 to arrive at the delivery station 150.
  • the process may use residue available from food manufacturers or vendors, such as vegetable markets and restaurants, the waste being processed to form the worm food prior to feeding the worms.
  • the waste may be minced together with cardboard, such as cardboard with organic glues.
  • the cardboard may be treated before use in a solution of water and lime (such as 1:50/L for h day).
  • Fresh, cooked food and shredded cardboard may be so mixed in a preset ratio. In this combination, the temperature may be kept in an acceptable range 19 to 24°C.
  • the food may comprise vegetable material, bakeries (eg bread crumbs) dairy products (eg cheese), cooked food and other organic materials.
  • a bottom layer (thickness of 4 to 5 inches, or 101 to 127 mm) of small shredded cardboard may be covered by a fine screen (plastic material - holes diameter - 0.2 to 0.5 mm).
  • a first layer comprising solid worm casting (thickness - 2 cm), which supplies enough nutrients for offspring and new babies.
  • this layer will act as an absorbent medium for leached material from the incoming food.
  • the worms may be set down on top of this layer in "strips" of 25 to 30 cm width, at an interval of about 25 cm apart.
  • the food may occupy the spaces between these strips. All of this may be covered with a thin layer of cardboard to protect against strong evaporation. In a closed environment this layer will not be necessary, it being sufficient to cover the bed with a very fine mesh (plastic material with very low density will usually suffice).
  • the worms may be "Reds” (Lumbricus Rubellus), although most commercially available types are suitable.
  • the process is carried out in subdued lighting or substantially in darkness.
  • Figure 6 illustrates a modified processing device 12a.
  • This is generally similar to the device 12 shown in Figure 4.
  • Like reference numerals denote like components in Figures 4 and 6.
  • the principal difference between device 12 and device 12a is that the base 31 is replaced by a modified base 31a which slopes across the width of the device 12 at an angle of, about 10 degrees.
  • the devices 12 are mounted for sliding movement on side walls 94 of the apparatus 15.
  • the side walls have channel-shaped rails 96 on which run rollers 98 attached to the sides of the devices 12. This permits more efficient use of stacking space for the devices and faster application of food.
  • the food can be added when the devices are slid outwardly after which they can be slid back into position between the walls 98.
