Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for treating waste, a method for using the treated waste, and a method for growing beetles using the waste. More particularly, the present invention relates to a method of treating waste by larvae of beetles, a method of using treated waste, and a method of growing beetles by waste.

2. Description of the Related Art Waste, for example, livestock waste from cattle barns of livestock farms, is becoming closer to ordinary households due to an increase in the development of residential land in the suburbs. In addition, the amount of garbage and sludge from general household life and food factories and the like is increasing year by year. Livestock waste is composted by giving a suitable temperature indoors and outdoors to promote spoilage, and turning back to improve air circulation. Most of the garbage is collected and incinerated by an incinerator.

[0003]

However, the compost obtained from livestock waste often gives off a bad smell during the composting process and generates wastewater due to rainfall and the like, thereby polluting the surrounding environment. When the obtained compost is mixed with a field or the like, it is difficult to spread uniformly because it is sticky, so that the working time tends to be long. In addition, incineration of the collected garbage in an incinerator requires a process of pulverizing it to a certain size and drying it before injecting it into the incinerator so that combustion can be performed efficiently. And the incineration costs were expensive. Furthermore, smoke and odor cannot be avoided during combustion, and the surrounding environment is polluted.

[0004] The present invention solves the above-mentioned problems, does not pollute the surrounding environment, and has a low processing cost.
An object of the present invention is to provide a method of treating waste and a method of using the treated waste, which can efficiently perform an operation of putting the treated waste into soil. Another object of the present invention is to provide a method for growing beetles by using wastes.

According to a seventh aspect of the present invention, there is provided a method for growing a beetle by using waste, wherein a step of adding a beetle larva to waste containing organic matter, a step of feeding the larva to an organic matter in the waste, A method for growing a beetle comprising:

[0012] In the eighth invention, the beetle growing method according to the seventh invention, wherein the beetle is a beetle.

The beetle includes a beetle, a scarab beetle, a caterpillar, and the like. In particular, a beetle that almost completely eats waste containing organic matter and produces a large amount of feces is preferable. In addition, examples of the waste containing organic matter include livestock waste from cattle barns of livestock farmers, garbage and sludge from general household life and food factories, and the like. Also, these mixtures are included. However, it is not limited to these.

(Action) In the method of treating waste with larvae according to the present invention, beetle larvae are added to waste containing organic matter, and the larvae are fed with organic matter in the waste. And the surrounding environment can be prevented from being polluted without emitting sewage due to rainfall. Further, the method of treating waste with larvae according to the present invention does not require a step of pulverizing or drying, unlike the method of treating with waste incinerators, and is inexpensive.

In the case where a larva of a beetle eats organic matter in waste and dung, the component obtained by decomposing the organic matter in the dung becomes nutrients for the crop, and the processed material can be used as a compost having excellent fertilizing effect. .

When the above-mentioned dung is solid, when it is used as a compost, it can be spread evenly without stickiness when mixed with a field or the like, and the working time can be shortened.

In the case where the beetle is a beetle, the larva almost completely eats waste containing organic matter and emits solid feces, so that it does not emit a bad smell during composting or the like. Without giving out
Pollution of the surrounding environment can be reliably prevented.

Beetles increase several tens of times in the process of treating waste containing organic matter, and as a by-product, their growth costs are low.

Example: In early April, the waste on the floor of a cowshed was loaded onto a dump truck with a loading capacity of 2 tons.
m, about 1 m in height, and laid down in a kamaboko shape. The composition of the waste was about 80% by weight of dairy cow dung, 5% by weight of cedar sawdust, 5% by weight of rice straw, and 10% by weight of enoki shavings (nonwoven fabric floor separated from enoki after cultivation). .
The periphery of the Kamaboko-shaped waste was surrounded by a tin. The tin had a height of 0.5 m above ground and a depth of 0.5 m buried underground. The underside of the galvanized iron is to prevent the infestation of moles that feed on the beetle larvae.

In the middle of July, 0.3 m wide and 0.4 m long,
Compost was placed in a 0.3 m deep plastic case, and seven pairs of adult beetles (either artificially grown or naturally grown in Yamano) were added (or planted). . The compost was produced in the previous year and is a good compost in which organic matter has been completely eaten by the beetle larvae and turned into feces. The beetle has been completely removed from the compost. Bananas, apples, peaches, etc. were given as feed for the adult of the above seven beetles. The adults laid eggs in mid-August, and the eggs became larvae in early September.

The larvae were immediately transferred from the surface of the Kamaboko waste so as to be evenly distributed in a layer having a depth of 5 cm. The larva continued to eat the organic matter in the waste (the waste was mostly composed of organic matter) until the end of May of the following year, and as a result, almost all the organic matter became solid feces and almost compost was completed. In late June of that year, a large number of pupae were growing in the almost completed compost, so we covered them with nets so that they would not escape when they became adults. In mid-July, the net was removed and the adults were dug out and collected. 20 to 25 adults could be collected per m ³ .

The amount of the compost obtained as described above is one-fifth that of the waste on the floor of the dairy cow shed used, and has an appearance indistinguishable from the surrounding soil. No sewage was given. In addition, the compost was granular having a diameter of about 5 to 10 mm, was low in water content, was porous and light, was non-adhesive, was easily sprayed on fields and the like, and was able to shorten the working time. And when the growth condition of the tomato when the said compost was used for a field was investigated, the favorable result was obtained compared with the compost of the comparative example manufactured without using a beetle (normal compost conventionally used). Good results were obtained even when used as a culture soil.
