The four classifications of garbage cans are hazardous waste, recyclable waste, kitchen waste and other waste, which correspond to the four colors of garbage cans: red, blue, green and grey. In addition to these four kinds of garbage cans, there are also yellow garbage cans, yellow garbage cans correspond to the medical waste garbage. The classification of garbage is to better deal with the garbage, to reduce the damage to the environment, but also can make some of the garbage to produce value again, to make use of waste.
Red trash can
Red color represents hazardous waste. Hazardous waste contains heavy metals that are harmful to human health, toxic substances, or waste that causes actual or potential harm to the environment. It includes batteries, fluorescent tubes, light bulbs, mercury thermometers, paint buckets, some appliances, expired medicines and their containers, and expired cosmetics. These wastes are generally disposed of using separate recycling or landfills.
Blue trash cans
Blue stands for recyclable trash, and the five main categories of recyclables include waste paper, plastic, glass, metal and fabric.
Green trash can
Green represents food waste. Food waste mainly includes leftovers, vegetable roots and leaves, bones, peels and other food waste. It can be composted on-site through biotechnology and can produce 0.6 to 0.7 tons of organic fertilizer per ton.
Gray trash can
Gray represents other waste, which includes other than the above categories of waste such as masonry ceramics, slag, toilet paper, paper towels and other waste that is difficult to recycle, as well as dust and food bags. Adopting sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
How many types of classified garbage cans are there?
1, recyclable garbage, recyclable trash cans are blue in color, mainly including waste paper, plastic, glass, metal and fabric of the five kinds of recyclable waste, will be collected and classified, not only to protect the environment, but also can be used for waste.
2, other garbage, other garbage cans color is yellow, also called dry garbage, mainly including the dirt, waste paper towels and other difficult to recycle waste, as well as daily clean up of the room generated by the dust, or left behind food bags. There are many different types of dry garbage, so you need to know them systematically so that you don't misclassify them.
3. Hazardous waste, the color of the trash can representing hazardous waste is red. Hazardous waste mainly includes waste that can harm human health or the natural environment, or has the potential to do so, such as hazardous heavy metals, discarded chemicals and so on.
4, food waste, food waste, also called wet waste, the color of the trash can is green. Kitchen waste is mainly generated in the catering space, including fruit and vegetable peelings, leftovers and other food waste, which can be collected and sorted for composting.
The four contents of the classification of the trash can
1, yellow trash cans are mainly recycled glass waste, such as wine glasses, bottles, flat glass, glass oil bottles and a series of glass products.
2, orange trash cans are mainly to collect hazardous waste, such as used batteries, used lamps, expired drugs, paint buckets and other hazardous waste.
3, blue garbage cans mainly collect recyclable garbage, such as paper, plastic bottles, iron and so on.
4, green garbage cans are mainly collected in addition to the above some of the garbage, such as cigarette butts, diapers, food waste, dust and so on.
The three major principles of waste classification:
1, divided and used principle: the purpose of classification is to divert waste disposal, the use of existing production and manufacturing capacity, recycling and utilization of recyclables, including material utilization and energy utilization, landfill disposal of temporarily unavailable useless waste. Classification is to increase the proportion of material utilization, reduce incineration, landfill disposal, if there is no subsequent utilization capacity, classification will lose its significance.
2, the principle of local conditions: localities, districts, communities, neighborhoods, geography, level of economic development, the ability of enterprises to recycle and utilize waste, the source of the residents, living habits, economic and psychological affordability and other ministries are the same, the need to take into account the actual situation, according to the local conditions, to provide the public with convenient and applicable software and hardware facilities, to play a convenient and guide the public to correctly classify the role of the people.
3. Consciousness and autonomy: Communities and residents, including enterprises and institutions, gradually develop the behavioral norms of reduction, recycling, consciousness and autonomy, and innovate the mode of garbage classification and treatment, and become the main force of garbage reduction, classification, recycling and utilization.
What are the four classifications of garbage cans?
Four kinds of garbage cans, they are recyclable garbage, food waste, hazardous waste and other garbage. Recyclable garbage mainly includes five categories: paper, plastic, glass, metal and fabric; food waste includes leftovers, bones, vegetable roots and leaves, fruit peels and other food waste; hazardous garbage contains heavy metals that are harmful to human health, poisonous substances, or wastes that cause actual or potential harm to the environment. Other garbage includes masonry ceramics, slag, bathroom waste paper, paper towels and other waste that is difficult to recycle and dust, food bags.
According to the unified symbol set by the state, household waste is divided into four categories, which are recyclable waste, food waste, hazardous waste and other waste.
1, recyclables
Recyclables mainly include five categories: paper, plastic, glass, metal and fabric.
Waste paper: mainly includes newspapers, periodicals, books, and all kinds of wrapping paper. However, note that paper towels and toilet paper are not recyclable because they are too water-soluble.
Plastic: all kinds of plastic bags, plastic foam, plastic packaging, disposable plastic lunch boxes tableware, hard plastic, plastic toothbrushes, plastic cups, mineral water bottles and so on.
Glass: mainly includes all kinds of glass bottles, broken glass pieces, thermos flasks and so on.
Metal objects: mainly including cans, can boxes, etc.
Fabrics: mainly include discarded clothes, tablecloths, washcloths, school bags, shoes, etc.
These wastes can be recycled through comprehensive treatment to reduce pollution and save resources. For example, each recycled 1 ton of waste paper can make good paper 850 kilograms, saving 300 kilograms of wood, than the same amount of production to reduce pollution by 74%; each recycled 1 ton of plastic beverage bottles can be obtained from 0.7 tons of secondary raw materials; each recycled 1 ton of scrap iron and steel can be refined 0.9 tons of steel, smelting with ore to save 47% of the cost of smelting to reduce air pollution by 75%, reducing 97% of the water pollution and solid waste.
2, other garbage
Other garbage includes in addition to the above types of garbage, masonry ceramics, slag, bathroom paper, paper towels and other difficult to recycle waste and dust, food bags. Adopting sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
The big stick bone is included in "other garbage" because it is "difficult to corrode". Corn kernels, nut shells, fruit kernels and chicken bones are kitchen waste.
Toilet paper: Toilet paper, toilet paper dissolves in water, and is not considered recyclable "paper", similar to cigarette boxes and so on.
Kitchen garbage bagging: the commonly used plastic bags, even if they are biodegradable, are far more difficult to corrode than kitchen garbage. In addition the plastic bags themselves are recyclable waste. The correct way to do this is to dump the kitchen waste into the garbage can, and throw the plastic bags into the "recyclable trash" barrel.
Shells: In the classification of garbage, "shells and peanuts" is identified as peanut shells, which do belong to food waste. Waste cooking oil used at home is also categorized as "food waste".
Dust: Dust belongs to "other garbage" in the garbage classification, but leaf litter belongs to "food waste", including flowers in the house.
3, food waste
Food waste includes leftovers, bones, vegetable roots, leaves, peels and other food waste. After biotechnology on-site treatment and composting, each ton can produce 0.6~0.7 tons of organic fertilizer.
4, hazardous waste
Hazardous waste contains heavy metals that are harmful to human health, toxic substances, or waste that causes actual or potential harm to the environment. It includes batteries, fluorescent tubes, light bulbs, mercury thermometers, paint buckets, some home appliances, expired medicines and their containers, and expired cosmetics. These wastes are generally disposed of using separate recycling or landfills.
What kind of garbage is in all four types of garbage cans
What kind of garbage is in all four types of garbage cans are recyclables, hazardous waste, other garbage, and food waste.
1, recyclables: said suitable for recycling and resource utilization of waste, including paper, plastic, glass, fabrics and bottles and cans, etc., collected in blue garbage containers.
2. Hazardous garbage: indicates garbage that contains hazardous substances and requires special safety treatment, including batteries, lamps and daily-use chemicals, etc., and is collected in red garbage containers.
3. Other garbage: indicates garbage other than those classified and is collected in gray garbage containers. Different colors of garbage cans represent the classified garbage, so the classified garbage cans are divided in this way.
4, food waste: mainly rice and flour food residues, vegetables, animal and vegetable oils, meat and bones, etc. In terms of chemical composition, there are starch, cellulose, protein, lipids and inorganic salts.
