How can we not cause garbage?

It's hard unless you don't live.

This is an international issue, and you need to talk to each other in person.

1. Incineration.

Incineration is a method in which garbage is placed in a high-temperature furnace to sufficiently oxidize the combustible components in it, and the heat generated is used for power generation and heating. The waste-to-energy system jointly developed by Westinghouse and O'Connor has been successful.

2. Composting will pile up domestic garbage into piles, keep it warm to 55 70 storage, fermentation, and decomposition with the help of microorganisms in the garbage. the ability to decompose organic matter into inorganic nutrients. After composting, household waste becomes hygienic, odorless humus.

3. Reduce the land occupation, some substances in the domestic garbage are not easy to degrade, so that the land is seriously eroded. Garbage classification, remove substances that can be degraded and are not easy to degrade, and reduce the amount of garbage by more than 60%.

4. Reduce pollution.

At present, China's garbage disposal mostly adopts sanitary landfill or even simple landfill, occupying tens of thousands of acres of land; And insects and flies fly around, sewage overflows, stench, and seriously pollutes the environment. Waste plastics in the soil can lead to reduced crop yields; Waste plastic discarded is accidentally eaten by animals, resulting in accidents that lead to the death of animals from time to time. Therefore, the use of ** can also reduce harm.

5. Turn waste into treasure.

China uses 4 billion plastic fast food boxes, 570 million instant noodle bowls, and billions of pairs of disposable chopsticks every year, which account for 8.15% of household waste. 1 ton of waste plastic can be used to recycle 600 kg of diesel. **1,500 tonnes of waste paper, exempt from the felling of trees used to produce 1,200 tonnes of paper.

The "Lvrong" brand "organic solid waste degradation furnace" produced by Linwei Environmental Protection is an organic waste terminal treatment equipment specially developed for the characteristics of scattered residence, inconvenient transportation and non-classification of garbage in China's rural population.

Garbage sorting. Then it is processed centrally.

The colors and labels of the classified garbage cans are represented as follows:

1. Red

Red represents hazardous waste. Hazardous substances include waste batteries, fluorescent tubes, paints, expired drugs, cosmetics, etc., and have certain pollution hazards.

2. Green

Green represents food waste. Kitchen waste can be used as fertilizer for plant nutrients, and after the soil is buried, it can be decomposed and absorbed by natural microorganisms and plants, playing a role in waste reuse.

3. Blue

The blue color represents the reuse of garbage, including plastics, paper, metals and other valuable substances, which will be included in the waste removal system for resource recycling.

4. Gray

In addition to hazardous substances and non-hazardous materials, bricks, ceramics, muck and other difficult wastes, such substances will generally be incinerated and buried.

The purpose of garbage classification is to improve the resource value and economic value of garbage, strive to make the best use of materials, reduce the amount of garbage treatment and the use of treatment equipment, reduce treatment costs, reduce the consumption of land resources, and have social, economic, ecological and other benefits.

Garbage belongs to the private goods of the public in the stage of classification and storage, and the garbage becomes a regional public resource in the community or community where the public is located after being classified and put into the public, and it becomes a public resource without exclusion after being sorted and transported to the garbage concentration point or transfer station. From the perspective of the methods of domestic waste classification in various cities at home and abroad, most of them are classified according to the composition and amount of garbage, combined with the resource utilization and treatment methods of local garbage.

1. Carry out garbage classification to facilitate garbage disposal.

2. Save resources and minimize the amount of garbage generated.

3. Develop good habits and do not litter.

4. Do not discard toxic and slag-based garbage, such as battery electronic devices, and deal with them in an uproar.

5. Use the garbage that can be used quietly to make the garbage recyclable.

According to the "quadrangle", domestic garbage can be divided into ** garbage, kitchen waste (perishable garbage), toxic and hazardous garbage and other garbage.

1. Waste includes waste paper, plastics, metals, textiles, electrical and electronic products, glass, plastic bags, packaging and other substances suitable for resource utilization;

2. Food waste includes discarded leftovers, leftovers, melon peel cores, residual branches and fallen leaves, vegetable stalks, leaves, carrion, bones, livestock and poultry products, offal and other perishable garbage generated in daily life;

3. Toxic and hazardous garbage includes waste batteries, electronic products, expired cosmetics, pesticides, waste lamps, waste paint buckets, expired drugs and other domestic garbage that causes direct or potential harm to human health or the natural environment;

4. Other garbage includes disposable tableware, cigarette butts, polluted paper, worn ceramics, dust, pet feces, etc.

The garbage generated in our daily life is not all to be completely discarded, and under the general trend of energy conservation and environmental protection, there are many garbage that can be recycled and turned into treasure. Even if it needs to be discarded, it is necessary to do a good job of scientific classification.

Objects, such as plastic, glass, metal, and waste books, newspapers and magazines, can be reused as renewable resources. Non-avoidable items, such as dust, kitchen waste, contaminated packaging products, etc., all need to be discarded. Dangerous items such as expired medicines, used batteries, light bulbs and tubes, etc., will cause environmental pollution if discarded, so they should be placed in a special trash can for special disposal.

Every 1 ton of waste paper can make 850 kg of paper, save 300 kg of wood, and reduce pollution by 74% compared with the same amount of production.

A large amount of food waste is generated in the kitchen every day, such as leftovers, food scraps generated during meal preparation, etc., if this kind of waste is not disposed of regularly, it will not only produce an unpleasant smell, but also cause garbage pollution. Eggshells, spices, and food packaging should be put into a special trash can and disposed of in a timely manner after a meal. Leftovers can be ground and broken up using a kitchen waste disposer installed under the kitchen sink before being discharged into the drain.

Some garbage generated in daily life will cause environmental pollution because it contains toxic and harmful chemicals, so it should not be discarded at will, but should be put into the designated garbage can. The more common ones are waste batteries and tube bulbs, and now there are almost no battery inlets on the trash can, so you can do your part by dropping the battery and throwing it in. Waste lamps contain chemicals that are harmful to the human body, so when discarding, they should not only be put in a fixed place, but also try to avoid lamp breakage.

Other garbage should also be scientifically classified, in addition to the above-mentioned garbage, there will also be wastes such as bricks, ceramics, muck and other difficult wastes in the decoration, which need to be incinerated or sanitary landfill in order to effectively reduce the pollution of groundwater, soil and air. The garbage in the decoration should not be mixed with domestic garbage, because the disposal methods of the two are different, and they should be strictly distinguished and discarded. Most of the current decoration has to apply for decoration permits in the community, so the waste generated in the decoration can be disposed of by the property in a unified manner, and we no longer need to do the landfill work by ourselves.

Obsolete clothing can be washed and donated to the welfare department, but it can also be reused in slippers or cloth bags. It is a pity that the old household appliances and furniture that can still be used are discarded after being eliminated, so it is better to send them to the second-hand market for sale. Milk cartons or buckets of mineral water can be used as storage boxes or daily necessities.

There are three main ways to treat domestic waste harmlessly in China: sanitary landfill, garbage composting and garbage incineration. At present, the main way to dispose of garbage is sanitary landfill.

The defects of sanitary landfills are also serious, taking up a lot of land resources, and the leachate of garbage will cause land or water pollution.

There are many types of garbage, and each garbage disposal scheme cannot be completely treated, so it will be better to sort and classify the garbage first, and then treat it separately according to different categories.

Garbage sorting equipment is a set of garbage treatment production lines with different garbage sorting function equipment.

Garbage disposal supporting sorting equipment, including crusher (bag breaking machine), trommel screen, cloth machine, dry cleaning machine conveyor, conveying equipment, manual sorting platform, belt conveyor, winnowing machine, magnetic separator, deodorization tower, baler, etc., can be combined according to different needs.

Through the garbage sorting equipment, the garbage can be divided into inorganic, organic, metal, plastic, etc., which will realize the harmlessness, recycling, and reduction of garbage to a greater extent.

Answer: Food waste: refers to the waste generated by people in the process of buying, selling, storing, processing and eating various foods.

This type of garbage is highly corrosive, decomposes quickly, and emits a foul odor. General garbage: including waste paper products, waste plastics, rags and various textiles, waste rubber, broken leather products, waste wood and wood products, broken glass, scrap metal products and dust, etc.

Ordinary garbage and food waste are the main objects that can be used in municipal waste. Construction waste: including soil, stones, concrete blocks, broken bricks, waste wood, waste pipes and electrical waste, etc.

This kind of waste is generally disposed of by the construction unit itself, but there is also a considerable amount of construction waste into the municipal waste. Garbage cleaning: including waste in public garbage bins, cleaning materials in public places, waste after road surface damage, etc.

Hazardous waste: including dry batteries, fluorescent tubes, thermometers and other hidden digestive and biological hazards, flammable and explosive materials and wastes containing radioactive materials. This type of garbage generally cannot be mixed with ordinary garbage.

There are three main ways to treat waste harmlessly: Landfill: landfill waste has less investment and large treatment capacity; The technical requirements are not high.

However, it has a large permanent footprint and has a high potential for pollution. In developed countries such as the United States, there have been incidents of landfill pollution decades later. Compost:

Disposing of garbage by composting can turn garbage into organic fertilizer. However, the fertilizer efficiency of this garbage fertilizer is low, the sales are limited, and there is not much room for development. Incineration:

Waste incineration has the advantage of being the most radical in terms of energy and waste reduction (80% to 95% reduction in waste volume after incineration), but this method is very costly. The construction of an incinerator with a daily waste processing capacity of 1,000 tons and attached thermal energy** equipment will cost about 7.8 billion yuan. Satisfied.
