If you want to understand domestic waste, you must understand its specific classification. Domestic garbage can generally be divided into four categories: recyclable garbage, kitchen garbage, harmful waste and other garbage. Today, our lovely little meow will introduce you to other rubbish, including what rubbish.

Other garbage is less harmful, but it has no reuse value. Other wastes include brick and tile ceramics, muck, toilet waste paper, porcelain fragments and other wastes that are difficult to recycle except the above-mentioned types of garbage. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air. In today's society, there is no effective way to dissolve other garbage, so it should be produced as little as possible.

Let's talk about the classification of domestic waste first.

Domestic garbage can generally be divided into four categories: recyclable garbage, kitchen garbage, harmful waste and other garbage. The commonly used garbage disposal methods mainly include comprehensive utilization, sanitary landfill, incineration and composting.

(1) recyclable garbage includes paper, metal, plastic, glass, etc. Through comprehensive treatment and recycling, pollution can be reduced and resources can be saved. If every 1 ton of waste paper is recycled, 850 kilograms of paper can be made, 300 kilograms of wood can be saved, and pollution is reduced by 74% compared with the same output; Every 1 ton plastic beverage bottle can recover 0.7 tons of secondary raw materials; Every recovered 1 ton of scrap steel can produce 0.9 tons of steel, which saves 47% cost compared with ore smelting, reduces air pollution by 75%, and reduces water pollution and solid waste by 97%.

(2) Kitchen wastes, including food wastes such as leftovers, bones, roots and leaves, are composted by biotechnology, and 0.3 tons of organic fertilizer can be produced per ton.

(3) Hazardous wastes include waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment.

(4) Other wastes include bricks and tiles, waste residue, toilet waste paper and other wastes that are difficult to recycle. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.

The above is a knowledge introduction about what other garbage includes. I hope everyone can raise their awareness of other garbage and enhance their awareness of environmental protection. Next, Bian Xiao will introduce you to the classification and treatment methods of domestic waste. Welcome to pay attention to this lovely little knowledge.
