Question 2: How many kinds of garbage are there? What are these kinds? What rubbish do they mainly recycle? Recyclable waste
Recyclable garbage is recyclable garbage. Pappe, cardboard, glass, plastic, metal and Kunststoffen can be reused themselves, or the materials can be recycled. Newspapers, magazines, advertisements and other clean paper related to these materials can be recycled. In addition, the green label (GrünenPunkt) on the package belongs to the DualeSystem to be paid, and also belongs to recyclable garbage.
Recyclable garbage mainly includes waste paper, plastic, glass, metal and cloth.
Waste paper: mainly including newspapers, periodicals, books, various wrapping papers, etc. However, pay attention to paper towels and
Waste sorting toilet paper is not recyclable because of its strong water solubility.
Plastics: mainly including plastic barrels, pots, bottles and plastic clothes hangers.
Glass: mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles and so on.
Metal objects: mainly including cans, cans, etc.
Cloth: mainly includes waste clothes, tablecloths, towels, schoolbags, shoes, etc.
These wastes can be recycled through comprehensive treatment, reducing pollution and saving resources. If every 1 ton of waste paper is recycled, 850 kilograms of paper can be made, 300 kilograms of wood can be saved, and pollution is reduced by 74% compared with the same output; Every 1 ton plastic beverage bottle can recover 0.7 tons of secondary raw materials; Every recovered 1 ton of scrap steel can produce 0.9 tons of steel, which saves 47% of the cost compared with ore smelting, reduces air pollution by 75%, and reduces water pollution and solid waste by 97%.
Folding kitchen garbage
Including food waste, such as leftovers, bones, roots, leaves, peels, etc. Through in-situ composting by biotechnology, 0.6-0.7 tons of organic fertilizer can be produced per ton.
Fold other rubbish
Mainly divided into medical waste and dry waste.
Dry garbage: garbage bags, discarded napkins, diapers, clean lime soil, heavily polluted paper, plastic bags, etc.
Medical waste: waste containing virus, such as cotton swabs with blood and scalpels. This kind of garbage needs special treatment and can only be buried after disinfection.
Folding toxic and hazardous waste
Waste containing heavy metals, toxic substances harmful to human health or actual or potential harm to the environment. Including batteries, fluorescent tubes, light bulbs, mercury thermometers, paint buckets, household appliances, expired drugs, expired cosmetics, etc. If the battery burns, it will hurt innocent people after explosion; Fluorescent tubes and bulbs, like the above batteries, radiate more; Mercury is more dangerous, it is a toxic substance ... so these wastes are generally recycled separately or specially landfilled.
Question 3: What kind of garbage do glass fragments belong to? 5 points can be recycled.
Glass is formed by melting sand and other chemicals (the main raw materials are soda ash, limestone and timely). Silicate nonmetallic materials form a continuous network structure during melting, and their viscosity gradually increases and hardens without crystallization during cooling. The chemical composition of ordinary glass is Na2O? Cao? 6SiO2, the main component is silicon dioxide.
The main raw materials for glass production are glass forming agents, glass modifiers and glass intermediates, and the rest are auxiliary raw materials. The main raw materials are oxides, intermediate oxides and out-of-network oxides introduced into glass to form a network; Auxiliary raw materials include clarifier, flux, opacifier, colorant, decolorant, oxidant and reducing agent.
At present, the glass container industry uses about 20% broken glass in the manufacturing process to promote melting and mixing with raw materials such as sand, limestone and alkali. 75% of broken glass comes from the production process of glass containers, and 25% comes from the capacity after consumption.
The transformation and utilization of recycled glass bottle packaging refers to the direct processing of recycled glass packaging and the utilization of other useful materials. This kind of utilization is divided into two types, one is heating type and the other is non-heating type.
Unheated type. Non-heating utilization is also called mechanical utilization. The specific method is to crush the recycled waste glass directly, or carry out pretreatment such as cleaning, sorting and drying, and then crush it into small particles by mechanical method, or grind it into small glass balls for later use. There are several ways of utilization: ① glass fragments are used as pavement assembly, building bricks, glass wool insulation materials and honeycomb structure materials; (2) The broken glass is directly mixed with the building material component * *, and the overall building prefabrication analysis is carried out; (3) The crushed container glass can also be used to make reflective materials and clothing decorations; ④ It is used to decorate the building surface to make it have beautiful optical effect; ⑤ It can be directly ground into various shapes, and then glued into decorations such as handicrafts or buttons. The mixture of glass and plastic waste can be molded into synthetic slate products. ⑦ It can be used to produce sewage pipes.
Heating heating utilization is to break waste glass, melt it in a high-temperature melting furnace, and then make glass fiber by rapid drawing. This kind of glass fiber can be widely used to make asbestos tiles, glass jars and various building materials and daily necessities. The production of glass bottles is one of the most energy-consuming packaging products. How to recycle glass packaging more effectively is a hot topic at home and abroad.
Question 4: What is recyclable garbage? Recyclable garbage refers to waste suitable for recycling and resource utilization, mainly including:
(1) Waste paper: newspapers, book paper, wrapping paper, office paper, advertising paper, cartons, etc. Note that paper towels and toilet paper are too water-soluble to be recycled;
(2) Plastics: all kinds of plastic bags, plastic foams, plastic packaging, disposable plastic lunch boxes and tableware, hard plastics, plastic toothbrushes, plastic cups, mineral water bottles, etc.
(3) Glass: glass bottles and broken glass pieces, mirrors, light bulbs, thermos bottles, etc.
(4) Metals: cans, tin cans, toothpaste skins, etc.
(5) Cloth: mainly includes discarded clothes, tablecloths, towels, cloth bags, etc.

4. Hazardous waste. Including waste batteries, expired pesticides, waste paints, waste lamps, waste daily chemicals and expired drugs.
Disposal method: Among the hazardous wastes, the environmental protection department together with the supply and marketing department will guide the rural areas to collect and transport them to the designated places for harmless treatment according to environmental protection requirements (the abandoned ponds must be sealed according to environmental protection standards).
5. Burning garbage. Waste tin foil, waste fabric, waste wood, garbage, etc. They are not suitable for recycling.
Disposal method: garbage with no recycling value, such as plant garbage such as litter, can be piled up on the ground for incineration, and then the lime soil can be returned to the field, and the waste cloth, waste tin foil, sugar paper and other chemical fibers can be sent to an environment-friendly high-temperature incinerator for incineration.
Question 8: Do plastic bags count as recyclable garbage? When you often want to distinguish between qualified and unqualified. Qualified plastics can be degraded for reuse. Unqualified plastics can't degrade naturally, that is, such plastics always keep this "finished plastic state" and can't return to the molecular state (such as C2H3Cl monomer) that constitutes plastics. Non-degradable plastics are also prone to produce unhealthy substances when exposed to high temperatures, so don't always put some hot dishes in plastic bags. Plastic bags in supermarkets are biodegradable. When you eat out, you sometimes need to pack. It is suggested to use lunch boxes instead of plastic bags.
