Description
-1- A METHOD AND APPARATUS FOR THE TREATMENT OF ORGANIC MATTER TECHNICAL FIELD 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.
BACKGROUND ART Domestic garbage contains a great deal of organic matter which, if processed correctly, may yield a number of useful agricultural substances, such as organic fertilisers, for example, and compost.
DISCLOSURE OF THE INVENTION 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 in the form of a stack of containers one on top of the other, the treatment assembly being provided with worm access means in the base of all but the lowest container in the stack enabling worms to migrate between containers in the assembly, placing organic matter in all but the lowest container in the stack, placing a 20 plurality of worms in at least the container adjacent the base of the stack allowing the worms to work their way upwards through the worm access means from container to container, removing the container adjacent the base of the stack when processing of organic matter therein is deemed to be sufficiently completed, moving the containers in cthe rest of the stack downwards, so that the container immediately above the removed -2container replaces the removed container in the stack, extracting desired materials from the removed container, and replacing the removed container at the top of the stack.
Preferably, further organic matter is placed in the container replaced at the top of the stack.
Preferably, the container newly placed adjacent the base of the stack in said step of moving the containers in the rest of the stack downwards, is in turn removed from the stack when processing of organic matter therein is deemed to be sufficiently completed, and the cycle repeated as desired by extracting desired materials from the removed container and replacing that container at the top of the stack.
Preferably, the lowest container in the stack has a closed base portion adapted to contain liquid draining from matter in the stack.
Preferably, the lowest container has a drain valve adapted to drain liquid ~contained therein, and the method includes the step of periodically draining liquid from the lowest container by opening the drain valve.
Preferably, the liquid so drained is utilised as a fertiliser.
The type of worms used are preferably earthworms. Different species may be used for different applications. 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 20 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 provides a form of "worm farm".
-3- The organic matter can comprise any convenient waste matter, such as vegetable matter, for example. In addition, to supplement or "pack" the waste matter further materials may also be included, such as soil, paper, etc.
In a preferred embodiment, the 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. In the stack the organic matter will take up completely the space between the base of one container and the adjacent container. The worm access means preferably contain perforations 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.
1 .15 When the treatment of the matter in a container is deemed to be completed, the container is 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 placed in the container and it is replaced in the assembly.
In a preferred embodiment, worms are initially placed in a base container in the go•* 20 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 S ~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 -4assembly 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.
Different types of organic matter may be used in the method and apparatus of the present invention depending upon the application. For example, where the primary application of the invention is in recycling organic matter from household garbage, e.g.
vegetable scraps, then household vegetable scraps will be slowly introduced to the treatment assembly for the worms to feed on and to break down. Where 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 S.:i are good worm feed.
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.
BRIEF DESCRIPTION OF THE DRAWINGS Features and advantages of the present invention will become apparent from the following description of an embodiment thereof, by way of example only, with reference •to the accompanying drawings, in which: Figure 1 is a perspective view of a container in accordance with an embodiment of the present invention; c~T Figure 2 is a plan view of the container in Figure 1; Figure 3 is a cross-sectional view through a stack assembly in accordance with an embodiment of the present invention; and Figure 4 is a partially cut-away perspective view of the stack assembly shown in Fig. 3.
MODES FOR CARRYING OUT THE INVENTION Figures 1 and 2 show a container arranged to be associated with a series of like containers to form a treatment assembly (Figure 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 (most clearly shown in Figure 3) are provided to enable %"the containers to be stacked together as shown in Figure 3, leaving a gap of *9 predetermined distance between the bases 2 of respective stacked containers. Projecting 15 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.
In operation, the containers are stacked together in a stack assembly, as shown
S
in Figure 3, on top of a base container 7. Unlike the other containers, the base container S: 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 container 7. Base container 7 has a port to which a stopcock 8 is secured to enable run-off of liquid 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 -6include 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.
As matter breakdown progresses and worm populations increase, the worms will tend to migrate upwards through the stack to find more food. After a period of time, breakdown of the matter in the lower containers of the stack will have progressed to a satisfactory level. When this occurs, 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 c 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 g:°1 20 cycled. Each time a container is removed from the stack a harvest of compost, 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.
-7- If a stack is regularly watered from the top or if the organic material us sufficiently damp, 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.
It will be appreciated that this "worm and fertiliser farm" need not be fuelled merely by domestic organic waste. Any other matter could be used instead. The build of the treatment assembly, the specific process used and the type if 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.
S"Breeding Worms
S
0 15 The preferred worms for breeding are red and tiger worms.
A specific procedure employing the method and apparatus of the present invention which facilitates the breeding of red and tiger worms is as follows: The base container 7 is set at a convenient height in a cool shaded position.
20 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.
-8- Tiger worms and/or red worms are emptied onto this bedding material and the lid 12 is placed on top of this container 1.
Two to three days are allowed to enable the worms to settle and begin working properly.
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 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 15 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.
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 20 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.
Recvcling Vegetable Scraps 4l a a b S a S 4* a.
-9- For recycling vegetable scraps as the primary application of the assembly, steps to of the procedure for breeding worms, as discussed above, are carried out and then the following steps carried out: Once the worms have eaten through the original compost or manure in the base and are coming to the surface, a thin layer of compost is placed over the surface, a cup full of vegetable scraps and a further thin layer of compost to encourage the worms to move to feeding on the scraps. It is preferable to slowly introduce the worms to feeding on scraps as they need to adjust to this new food after feeding on other organic matter.
When the worms have eaten through this material and are on the surface. A second container is placed on top of the first container 1 and a small quantity of scraps covered by another thin layer of compost are put on the base of the second container.
Continue to slowly increase the amount of vegetable scraps fed with 15 some compost of required. The worms will adjust to eating only the vegetable scraps in a short period of time. The amount of scraps fed should, however, still be only what the worms can handle fairly readily. As the number of worms increase, they will be capable of converting larger quantities of scraps to castings.
Proceed as from step on breeding worms.
0000 0 20 Fattening Bait Worms 0 0 Large tropical worms are preferred for this.
The procedure for fattening the worms is as follows.
Follow steps and for breeding worms.
S(3) The large tropical worms do well on compost feeds and manures, A) particularly cow manure but once again avoid chicken manure. Place a layer of feed in a first container 1 placed on the base container. If the manure is dry, re-wet by soaking in water for a period of time.
and as for breeding worms.
Well moistened manure and compost can continue to be fed. Pollard or any fine textured grain product can also be fed at times to toughen the worms. Grain products, however, should only be fed in small amounts that the worms can consume in a couple of days.
and as 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.
Variations and modifications may be made to the invention described previously as indicated by the following statement of claim.
