Introduction to issues that should be paid attention to in garbage classification

my country's domestic waste is basically divided into four major categories, food waste, recyclables, hazardous waste and other waste. Garbage classification is of great significance. It can not only reduce environmental pollution and save land resources, but also improve people's values ??and make better use of renewable resources. The following is an introduction to the issues that I need to pay attention to when classifying garbage. I hope you like it!

How to reduce domestic waste

1. Avoid using disposable items and choose ones that can be used repeatedly. Durable products that are recyclable and repairable. Please bring your own tableware when dining out and avoid using disposable tableware. Please bring your own reusable cloth bags when shopping. Avoid buying bottled water, have a drinking water filter at home, and use reusable water bottles. Instead of using paper towels, use a small towel or handkerchief. Purchase rechargeable batteries and chargers to reduce hazardous waste.

2. Reduce packaging The easiest way to reduce packaging is to reduce consumption, buy the products you really need, and choose products with the least packaging as much as possible. When purchasing fruits and vegetables, please choose local products in bulk and avoid out-of-town products that are well packaged and transported over long distances. This not only reduces waste but is also more nutritious.

3. Compost food waste. Don’t throw away food scraps. You can use them to compost and fertilize flowers and plants.

4. Recycling: Understand what items are recycled locally. Generally, recyclable materials include paper, cardboard, aluminum cans, glass, scrap metal, used batteries, bottles, foam plastics, etc.

5. Donate idle items. Send the well-preserved idle items at home to local second-hand stores, flea markets or charities.

6. Electronic payment Set up electronic bank automatic payment, pay water, electricity, gas and even insurance premiums, and let the bank send electronic invoices to your email.

7. Public education: Help colleagues, neighbors and schools understand local information about waste disposal.

8. Volunteer cleaners Volunteer to clean the streets and alleys. Even if everyone picks up a piece of trash on the ground, it can make a huge difference to the urban environment.

Garbage disposal method and process

1. Recycling Separately place recyclable garbage and domestic garbage. Recycling garbage mainly includes metal, paper, and plastic products. Recyclable plastic products are sent to factories that use them as raw materials to produce plastic bottles for milk, juice, detergent, car oil, etc., while paper products are used to make cartons. This kind of carton can be recycled many times and used repeatedly.

2. Sanitary landfill Landfill treatment requires a large amount of land. At the same time, harmful components in garbage can also cause serious pollution to the atmosphere, soil and water sources, not only destroying the ecological environment, but also seriously endangering human health.

3. Composting: Composting requires sorting and classifying garbage, which requires a high organic content. Moreover, composting cannot be reduced and still requires a large amount of land.

4. Incineration The incineration method can generally significantly reduce the volume of garbage, greatly reduce the land occupation, and can recover heat energy for domestic heating and power generation. Incineration is a municipal solid waste treatment technology widely used in some economically developed countries in the world. The flue gas from garbage incineration is discharged after purification, and a small amount of remaining residue is discharged, landfilled or used for other purposes. Its advantages are rapid volume reduction capability and complete high-temperature harmlessness, small footprint, small impact on the surrounding environment, and heat recovery. Therefore, incineration of garbage is an effective method of harmlessness, reduction and resource utilization.

Common misunderstandings about garbage classification

Myth 1: Toilet paper is paper, and it can also be recycled. Toilet paper dissolves when exposed to water, and is not considered recyclable "paper". Similar things are There are ceramic supplies, cigarette cases, etc. Misunderstanding 2: Peanut shells belong to other garbage. The logo of "Peanut shells and melon rinds" is peanut shells, which belong to kitchen garbage. Waste cooking oil left at home is currently also classified as "kitchen waste".

Myth 3: Big stick bones belong to kitchen garbage. In fact, big stick bones are classified as "other garbage" because they are "hard to corrode". Similar ones include corn kernels, nut shells, fruit cores, etc., but chicken bones and the like are kitchen waste.

Misunderstanding 4: Bag kitchen garbage and throw it into the trash can. Even if the commonly used plastic bags are biodegradable, they are far more difficult to corrode than kitchen garbage. In addition, the plastic bag itself is recyclable garbage. The correct way is to throw the kitchen garbage into the trash can and the plastic bag into the "recyclable garbage" bucket.

Misunderstanding 5: Dust and fallen leaves belong to other garbage. In Hangzhou's garbage classification, dust belongs to "other garbage", but fallen leaves and fallen branches belong to "kitchen garbage", including flowers that have bloomed at home.

Misunderstanding 6: Quick-frozen dumplings and tofu packaging boxes are garbage generated in the kitchen and are kitchen garbage. Disposable tableware and food packaging bags are classified as "other garbage". In addition, used napkins, toilet paper, smoked cigarette butts, and old clothes also belong to "other garbage."

Myth 7: Thermos bottle galls are toxic and harmful, just like used lamps. The thermos bottle gall itself is made of glass and has a thin layer of mercury, so it should be classified as other garbage. In addition, correction fluid and the like are not very toxic and can also be classified as other garbage. Generally, hazardous, infectious, flammable and explosive waste is classified as hazardous waste. There are not many toxic and hazardous wastes generated in residents' lives, such as mousse for hair, which has a pressure container inside, which is flammable and explosive; another example is leftover perfume, which contains a lot of alcohol and is easy to volatilize. This category can be used as Hazardous waste disposal.
