Description

Recycling method of general waste and its device

The present invention relates to a method for treating and recycling general waste, and more particularly, to a method for recycling general waste, which collects general waste, separates recycled waste except flammables, and solidifies the remaining combustible waste. Relates to a device.

In general, general waste except industrial waste is landfilled in landfills in plastic bags, and some of the food waste is collected separately and recycled through fertilization or feed process, but when food waste is fertilized, Most of the general wastes and wastes have not been completely removed because they greatly hinder the growth of plants and feed the food wastes. Landfills will be buried together.

However, when landfills are disposed of in general, enormous lands are encroached, so it is not easy to secure landfills, and because of the leachate from the landfills, the water quality is contaminated and severe odors and gases are generated. There are many problems, such as a huge expense to prevent.

The present invention is to solve the above-mentioned problems, it is necessary to collect the general waste and then to recycle the general waste by separating the recyclable waste excluding flammable by using a recycling apparatus and solidifying the remaining combustible waste. The purpose of the present invention is to provide a method and a device for recycling waste of general waste, which can greatly reduce the cost, as well as almost no landfill, thereby completely preventing environmental pollution from landfilled waste.
