Talking about the Significance of Garbage Classification
Each of us produces a lot of rubbish every day. So, what should we do in the face of so much rubbish?
The traditional landfill method covers tens of thousands of acres; Moreover, insects and flies fly around, sewage overflows and stinks, which seriously pollutes the environment and affects the lives of urban people. Later, the classified collection and treatment of garbage made obvious progress.
The so-called garbage classification is to classify and discharge garbage with similar quality and nature, put it into different temporary storage containers according to the needs of treatment, and put it into the designated place according to the specified time, place and type, and recycle it uniformly and enter the corresponding treatment system. The purpose of garbage sorting is:
1. Resource recovery
Resource wastes in garbage, such as paper, metal, plastic, etc., can not only produce obvious economic benefits and protect resources, but also reduce the burden of garbage disposal if they are recycled through certain processes.
2. Appropriate handling requirements
Garbage classification can sort out non-degradable plastics, huge garbage and harmful substances, prolong the burial life, improve the surrounding air and water quality, and achieve higher sustainable development.
Avoid poisoning
Harmful wastes such as mercury batteries and mercury lamp tubes will produce harmful pollutants if burned, but if buried, heavy metals may seep out, causing pollution and destruction of soil and groundwater. Therefore, it is particularly important to classify these substances for special treatment.
Step 4 Reduce waste
Garbage classification is the primary key to garbage reduction, and garbage classification can maximize the application of limited resources.
It can be said that garbage classification can reduce the treatment cost and the consumption of land resources, and has social, economic and ecological benefits. The advantages of garbage sorting treatment are as follows:
1. Reduce land occupation
Some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage classification, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 60%.
2. Reduce environmental pollution
Waste batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human body. Waste plastics in soil will lead to crop yield reduction; Waste plastics are eaten by animals by mistake, resulting in accidents of animal death. So recycling can reduce the harm.
turn waste into treasure
China uses 4 billion plastic fast food boxes, 500-700 million instant noodle bowls and billions of disposable chopsticks every year, accounting for 8- 15% of domestic garbage. 1 ton of waste plastics can recover 600kg of diesel oil. Recycling 1500 tons of waste paper can avoid cutting down trees used to produce 1200 tons of paper. A ton of cans can be melted to form a ton of good aluminum blocks, and 20 tons of aluminum ore can be mined less. 30%-40% of the production waste can be recycled, so we should cherish this small-scale and large-scale resource. You can also use cans as pencil boxes, which is environmentally friendly and saves resources.
