Classification of garbageFrom me
Recoverable garbage
I know the sort of garbage
1. Classification of wastes
The classification of wastes is the sum of a series of activities that have been transformed into public resources by classifying them as storage, sorting and sorting and moving according to certain provisions or criteria. The purpose of the classification is to increase the resource and economic value of the waste and to maximize its use。
Waste classification criteria
Life trash is usually the sameRecoverable, hazardous waste, cooking waste, other waste。
3. Categorization of wastes
Recoverable collection containers are blue, hazardous waste collection containers are red, surplus garbage collection containers are green and other garbage collection containers are grey。
There are four categories of garbage
1 waste from cooking: food-type garbage from kitchens and fruit peels。
2 recoverable waste: wastes that are of high value for recycling and have access to waste recovery channels。
3 harmful waste: waste containing toxic and harmful chemical substances。
4 other garbage: total name of all waste except recyclable waste, hazardous waste, and surplus waste。
How do you classify the garbage
1. Waste cooking
These include, inter alia, leftovers, leftovers and western foods, food residues such as pastries, vegetable leaves, internal body parts of animal bones, tea slags, fruit residues, fruit shells, leaves leftovers of plants such as pelvis, abandoned food oil, etc。
2. Recoverable waste
These include, inter alia, paper (newspapers, leaflets, magazines, old books, cardboard boxes and other uncontaminated paper products), metals (iron, copper, aluminium, etc.), glass (glass bottles, flat glass and other glass products), plastics in addition to plastic bags (foam, plastic bottles, hard plastics, etc.), rubber and rubber products, milk boxes etc., beverage bottles (cola cans, plastic beverage bottles, beer bottles, etc.)。
3. Harmful waste
These include, inter alia, batteries (cells, button batteries, etc.), used electronics, used lamp bulbs, expired medicines, expired cosmetics, dyes, pesticide containers, herbicide containers, waste mercury thermometers, waste paint drums, spent printer cartridges, aluminum drums, etc。
4. Other garbage
These include, inter alia, contaminated and non-renewable paper (paper cups, photographs, duplicate paper, compact paper, receipt paper, postcards, photo albums, toilet paper, diapers, etc.), contaminated or other non-recoverable glass, plastic bags and other contaminated plastics, used clothing and other textiles, worn ceramics, women's hygiene items, disposable dishes, shells, cigarettes, dust, etc。

Waste classification flow chart
The classification of wastes is done at source by different components, attributes, utilization values and impacts on the environment, as well as by a number of categories with different attributes, according to the requirements of the different disposal methods, for purposes of disaggregated collection, classification, transport and classification。
Waste classification process
Meaning of classification of waste
Waste disposal and dumping in most parts of china is also an irresponsible way of “thinking one's own and leaving others alone”, i. E., by moving garbage. Most, however, use open dumps or landfills, causing serious secondary contamination. Thus, the question of how to treat urban waste in a timely and efficient manner and meet the objectives of sound, resource-efficient and quantitative reduction, consistent with the requirements of sustainable development, has yet to be addressed。
01
Full recycling, retrievable use, waste
Useful materials, such as paper, plastics, rubber glass, bottled tanks, metals and used household appliances, are sorted and collected by classification, and are then recycled, used and disposed of. This way, both the garbageResource utilizationLevels, which in turn reduce waste disposal, are important ways and means to achieve waste minimization and resourceization。
02
Reducing environmental pollution
A random or simple landfill would contaminate the soil, groundwater sources and air; it would also breed a large number of mosquito flies and bacteria, contagious diseases and directly endanger the physical and mental health of people。
03
Reducing waste disposal and disposal costs
Collection of wastes by classification facilitates the sorting of different types of waste. For example: composting and fermentation of cooking waste, fermentation of organic components into agricultural fields and fertilization for greening; burning of other wastes to recover thermal energy. The disposal of treated residues, such as composting or incineration, in sanitary landfills can reduce the amount of landfills and the area they occupy, thus achieving reduced waste disposal and disposal costs。
