Definitions

• the present invention relates to a method and apparatus for the treatment of organic matter and, particularly, but not exclusively, relates to a method and apparatus for the treatment of organic waste matter from domestic garbage.
• the present invention also relates to a method and apparatus which facilitates the breeding of worms or the fattening of worms for bait.
• the present invention provides a method of treating organic matter, comprising the steps of providing a plurality of containers adapted to be associated together to form a treatment assembly, the treatment assembly being provided with worm access means enabling worms to migrate between containers in the assembly, placing organic matter in the containers, placing a plurality of worms in at least one container, associating the containers to form a treatment assembly and leaving the containers for a time period to enable the worms to process organic matter and migrate from one container to another.
• the type of worms used are preferably earthworms.
• the worms In breaking down organic matter, the worms produce a number of useful substances, including worm leavings which are useful as manure and, if the waste is regularly watered, the worms produce liquid castings as fertiliser which can be run off from the assembly. This is in addition to the fact that compost is also produced. Further, in ideal conditions the worms will reproduce,- and can themselves be “harvested” . As well as an organic treatment method, therefore, the present invention also preferably provides a form of "worm farm" .
• the organic matter can comprise any convenient waste matter, such as vegetable matter, for example.
• the waste matter further materials may also be included, such as soil, paper, etc.
• a plurality of containers are stackable together, one within the other. Spaces remain between the respective bases of the containers for containing organic matter. Worms are preferably initially placed in one container only. The organic matter in this container will therefore be treated first .
• the worms will then tend to migrate to other containers to treat the organic matter therein.
• the organic matter will take up completely the space between the base of one container and the adjacent container. Perforations are preferably provided in the base of the adjacent container to enable worm migration.
• Worms may also migrate from one container to another due to an increase in worm population. In practice migration may occur due to both of these factors, i.e. completion of breakdown of organic matter and increase in worm population.
• the container is preferably removed from the assembly in order to enable extraction of the useful compounds and harvesting of worms remaining in the container. Further organic matter is then preferably placed in the container and it is replaced in the assembly.
• worms are initially placed in a base container in the stack assembly. The worms tend to migrate upwards as population increases and/or as organic matter breakdown proceeds. Containers- from the lower part of the stack can therefore be removed from the stack for extraction processing and replaced at the top, with further organic matter. This "cycling" of the stack assembly facilitates continuous processing.
• the top of the container of the stack assembly is preferably provided with a lid to keep out pests such as flies, for example.
• the bottom container of the stack assembly preferably has a solid bottom and walls to prevent egress of matter and worms, and is preferably provided with a port to enable liquid run-off to be taken from the assembly.
• the present invention further provides an assembly for treating organic matter comprising a plurality of containers adapted to be associated together such that at least some of the containers are adapted to hold organic matter and can be moved to replace one another in the assembly in a cyclical manner, and worm access means enabling worms to migrate between the containers adapted to hold organic matter.
• each container has a base and a peripheral wall and wherein the containers are adapted to be associated together by stacking in such a manner that a predetermined spacing exists between the bases of adjacent containers.
• the worm access means comprise perforations in the bases of all but the lowest container in the stack.
• organic matter may be used in the method and apparatus of the present invention depending upon the application.
• the primary application of the invention is in recycling organic matter from household garbage, e.g. vegetable scraps
• household vegetable scraps will be slowly introduced to the treatment assembly for the worms to feed on and to break down.
• the primary application of the assembly is, however, the fattening of worms for bait or the breeding of worms, then more conventional worm feeds may be used as the organic matter.
• Organic matter from domestic garbage may provide some of the worm feed in these applications or may not be included at all . Animal manures may be used instead, which are good worm feed.
• the assembly In setting up the treatment assembly, preferably the assembly will be constructed over a period of time rather than immediately, a container at a time.
• the containers are added as the treatment progresses and/or worms are fattened and/or worms are bred.
• Figure 1 is a perspective view of a container in accordance with an embodiment of the present invention
• Figure 2 is a plan view of the container in Figure
• Figure 3 is a cross-sectional view through a stack assembly in accordance with an embodiment of the present invention.
• Figure 4 is a partially cut-away perspective view of the stack assembly shown in Fig. 3
• Figures 1 and 2 show a container arranged to be associated with a series of like containers to form a treatment assembly ( Figure 3) .
• the container has side walls 1 and a base 2 for supporting organic matter therein.
• Base 2 has a plurality of perforations 3 through it to enable worms to enter the container through the base 2.
• the nature of the perforations is more clearly shown in Figure 2, although only part of the base is shown in detail in Figure 2, the rest of the base being the same as the portions detailed.
• Projecting portions 4 are provided to enable the containers to be stacked together as shown in Figure 3, leaving a gap of predetermined distance between the bases 2 of respective stacked containers. Projecting portions 4, in operation, are supported by rim portions 5 of the containers below them in the stack.
• the containers also have handles 6 incorporated in the walls 1 to enable ease of handling and transport.
• the containers are stacked together in a stack assembly, as shown in Figure 3, on top of a base container 7.
• the base container 7 does not have any perforations in its base. Worms can therefore only leave the container 7 or enter it through the open top of the container 7.
• Base container 7 has a port to which a stopcock 8 is secured to enable run-off of fluid from the stack assembly.
• Appropriate organic matter 10 is placed within the stacked containers in the gaps between their respective bases, as indicated in Figure 3.
• the organic matter may include vegetable matter, waste meat matter, and any other appropriate matter. Filler matter may also be incorporated, such as newspapers, soil, etc.
• Worms such as the common earthworm, are then placed in one of the containers. Preferably they are placed in the container adjacent to the base container 7. In a preferred method, the stack is built up slowly, so that some time will be given for the worms to break down the matter in the container adjacent to the base container before a third container is placed on top.
• a preferred height of the stack is limited to four containers, as is illustrated in Figure 3.
• the worms will tend to migrate upwards through the stack to find more food.
• breakdown of the matter in the lower containers of the stack will have progressed to a satisfactory level.
• the container in question for example the container adjacent to the base container 7, is removed from the stack. Its place is taken by the next container in the stack. In other words, the rest of the containers in the stack move down one container.
• the container that has been moved is processed to remove the useful products, such as worm faeces and compost which provide useful fertilisers, and worms themselves . Further organic matter for breakdown is then placed in the container and it is put back on top of the stack. In this way the containers (except the base container) are cycled. Each time a container is removed from the stack a harvest of compost, fertilising compounds and also worms are extracted.
• useful products such as worm faeces and compost which provide useful fertilisers, and worms themselves .
• Further organic matter for breakdown is then placed in the container and it is put back on top of the stack. In this way the containers (except the base container) are cycled.
• fertilising compounds and also worms are extracted.
• the preferred number of containers in the final assembly is four, being three containers 1 and one base container 7, although other numbers of containers could be used.
• the worms also produce a useful liquid fertiliser. Liquid run-off can be taken out of the port and stopcock assembly 8 and the liquid fertiliser extracted.
• a lid 12 is arranged to clip onto the top container of the stack to keep out pests, such as flies.
• the lid has vents (not shown) to allow the assembly to "breathe” as well as keeping out as much light as possible. Worms work better in the dark.
• this "worm and fertiliser farm" need not be fuelled merely by domestic organic waste. Any other matter could be used instead.
• the invention merely provides a very convenient method of breaking down organic matter.
• the build up of the treatment assembly, the specific process used and the type of organic matter or "worm feed" used in the treatment assembly will vary depending upon the particular application to which the treatment assembly is to be put. Three specific procedures are discussed in the following section relating in turn to breeding worms, recycling vegetable scraps and fattening bait worms.
• the preferred worms for breeding are red and tiger worms.
• the base container 7 is set at a convenient height in a cool shaded position.
• a container 1 is placed on the base container 7 and the base 2 is covered with a shade cloth.
• a layer (in the order of 8 centimetres) of bedding material e.g. animal manures (not chicken manure) compost (past heating stage) or a mixture of both placed in the container 1.
• bedding material e.g. animal manures (not chicken manure) compost (past heating stage) or a mixture of both placed in the container 1.
• Small amounts of feed such as compost, manure, vegetable scraps (e.g. from domestic garbage) , etc may now be added at regular intervals as the worms require it until the maximum level for organic matter in the container is reached.
• the maximum level of organic matter will be arranged such that the top layer of organic matter is adjacent to the base 2 of a further container to be placed on top of the first container 1. This level is preferably marked on the container 1 for convenience.
• a further container 1 is placed on top of the first container 1 and organic matter is placed in the further container in a gradual manner as for the first container 1 above. Worms will begin to migrate into the further container.
• a third container is likewise placed on the assembly when the organic matter level in the second container 1 has built up to the marked level. Each time the lid will be placed on the final container. (9) The worms progressively move upwards through the assembly and in time the contents of the lowest container 1 will have been converted to worm castings (useful for manure) and will contain some worms and worm capsules. These can now be harvested. After emptying this container 1, it may now be used on the top of the assembly, so that rotation continues. As this process goes on any excess liquid, including worm liquid castings, will form in the base container 7 and may be run-off. Worm numbers will increase to such a degree that it will be necessary to harvest the worms regularly. Recycling Vegetable Scraps
• steps (1) to (5) of the procedure for breeding worms are carried out and then the following steps carried out;
• step (9) Proceed as from step (9) on breeding worms. Fattening Bait Worms Large tropical worms are preferred for this.
• the procedure for fattening the worms is as follows. Follow steps (1) and (2) for breeding worms.
• the bottom container 1, once it is full of castings and egg capsules can be emptied into a container to allow the hatching of baby worms from the capsules .
• Baby worms can supply you with future stock for your bait fattening kit.
