Waste separation plays a vital role in waste collection and waste disposal. The three main methods of garbage disposal are sanitary landfill, incineration and composting. Different garbage is suitable for different treatment methods, and different garbage can provide different resources, for example, paper garbage, plastic garbage and medical garbage are suitable for incineration, and electricity and heat can be obtained through incineration of garbage; kitchen garbage is suitable for composting, and can be transformed into treasures through a special process, and can provide fertilizers for agricultural production; bottles and packages can be recycled and reused, thus reducing the waste of resources. The bottle packaging can be reused through recycling, thus reducing the waste of resources. One of the reasons why foreign countries occupy an advanced position in waste disposal is that they do a very good job in waste classification, which improves the efficiency of waste disposal and is conducive to the sustainable development of resources.
If you want to do a good job of categorizing garbage, you should start with the smallest thing, which is not littering.
