Interesting Trivia on Garbage Classification 1. What are the Trivia on Garbage Classification

Benefits of Garbage Classification

The benefits of garbage classification are obvious. The benefits of garbage sorting are obvious. Garbage sorted and sent to factories instead of landfills saves land, avoids pollution from landfills or incineration, and can be turned into treasures. For example, waste batteries are known as "miniature killers", as we all know that batteries in our lives contain heavy metals such as mercury or cadmium, and if these heavy metals are left in the ground, they can easily enter into the groundwater through the leaching of rainwater, which will cause serious persecution to the water resources and the land. However, waste batteries contain a variety of useful metal minerals, recycling value is very high. Because of the serious harm and special recycling value of waste batteries, many countries strictly prohibit them in the garbage and garbage mixing, Japan's community special yellow barrels, will be button batteries, etc. put separately. Again, such as leftovers lettuce, egg shells and peels, picking a class of kitchen garbage and other biological waste, but they can be used to make good organic fertilizer. Like the locust tree community in this big Nano dream biological waste treatment machine, can be biological waste drying, crushing, made of efficient organic fertilizer. Residents can use it to grow flowers and grass. Vegetables grown with them are safer and healthier than chemically fertilized food, and are quite popular in supermarkets. Biological waste usually accounts for 40% of the total waste, if they can be turned into organic fertilizer, not only to save land for landfills, but also to save vehicles and energy to transport them, but also to prevent them from breeding flies and bacteria.

So, there are many benefits of waste classification.

Introduction of environmentally friendly trash cans

Generally speaking, the common environmentally friendly trash cans are divided into green, yellow, and red.

The green one is for recyclable waste, recyclable waste: paper, plastic, rubber, metal, glass, etc.

The green one is for recyclable waste.

Yellow for non-recyclable garbage, non-recyclable garbage: mainly kitchen garbage, including fruit peels, vegetable

skins, leftovers, etc.

Red for non-recyclable garbage.

Red put toxic and hazardous waste toxic and hazardous waste: batteries, fluorescent tubes, mercury thermometers,

paint buckets, medicines, cosmetics, etc..

2. General knowledge of garbage classification

From the domestic and foreign cities on the classification of household garbage method, roughly according to the composition of the composition of the garbage, the amount of production, combined with the local garbage resource utilization and processing methods to classification. For example, Germany is generally divided into paper, glass, metal, plastic, etc.; Australia is generally divided into compostable garbage, recyclable garbage, non-recyclable garbage; Japan is generally divided into combustible garbage, non-combustible garbage, and so on. Nowadays, domestic garbage in China can be divided into four categories: recyclable garbage, food waste, hazardous garbage and other garbage. At present, the commonly used waste treatment methods are: comprehensive utilization, sanitary landfill, incineration power generation, composting, resource return.

Recyclable garbage

Mainly includes waste paper, plastic, glass, metal and cloth five categories.

Food waste

Includes leftovers, bones, roots, leaves, peels and other food waste

Hazardous waste

Includes waste batteries, waste fluorescent tubes, waste silver thermometers, expired medicines and so on, which require special and safe treatment.

Other garbage

Including brick and tile ceramics, slag, toilet paper, paper towels and other hard-to-recycle waste in addition to the above categories of garbage, taking sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.

3. Seek some garbage classification knowledge

Recyclable garbage

Mainly includes waste paper, plastic, glass, metal and cloth five categories. Waste paper: mainly including newspapers, periodicals, books, all kinds of wrapping paper, office paper, advertising paper, cardboard boxes, etc., but pay attention to the paper towels and toilet paper due to the water solubility is too strong can not be recycled. Plastic: mainly including various plastic bags, plastic packaging, disposable plastic lunch boxes and cutlery, toothbrushes, cups, mineral water bottles, toothpaste skins and so on. Glass: mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos flasks and so on. Metal objects: mainly cans, can boxes, etc. Fabrics: mainly including discarded clothes, tablecloths, washcloths, schoolbags, shoes, etc. Recycling through comprehensive treatment can 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 get 0.7 tons of secondary raw materials; each recycled 1 ton of scrap iron and steel can be smelted 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.

Kitchen waste

Including leftovers, bones, vegetable roots and leaves, peels and other food waste, composted by biotechnology in-situ treatment, each ton can produce 0.3 tons of organic fertilizer.

Hazardous waste

Includes waste batteries, waste fluorescent tubes, waste silver thermometers, expired medicines, etc., which require special safe treatment.

Other garbage

Including masonry ceramics, slag, toilet paper, paper towels and other hard-to-recycle waste in addition to the above categories of garbage, usually according to the characteristics of the garbage to take the way of incineration or landfill treatment.

4. Trash sorting

Trash sorting

In Germany, it is very important to dispose of trash. If you throw it in the wrong place, the whole neighborhood may suffer.

In 2002, I studied in Germany, studying for a master's degree in environmental engineering, and I also worked in a garbage recycling company after class, so I felt the importance of environmental protection to the Germans.

It took me a month to figure out how to dispose of garbage

Germany has the highest recycling rate in Europe, and a very sophisticated waste sorting system.

Household waste can be divided into five categories: organic waste, recyclable packaging, paper, glass products and batteries. Different waste is collected in different garbage cans, and the garbage cans are often placed in different places for ease of collection. One of the first things I did when I found my house in Germany was to ask my neighbors for advice on how to properly throw away trash, and it took me a whole month to fully understand.

The trash cans are rarely open, and are basically designed with a sliding lid. When you throw out the trash, you have to push the lid open, and when you let go, the lid automatically returns to its original position. This has two advantages: one is to prevent rain falling into the box, the dumpster into a water tank. Secondly, it can reduce the odor to escape.

Street garbage cans, cover the plastic bags are generally divided into yellow and blue. The former collects recyclable garbage such as paper packaging, and the latter holds household garbage such as fruit peels.

The kitchen garbage cans are generally required to cover the blue plastic bags, usually leftover food, fruit scraps and so on are thrown here. When the bag is full, tie a knot and carry it to a designated place outside the house, and the cleaners will know how to classify the bag by looking at its color.

Organic waste (food, etc.) is usually incinerated or landfilled in Germany, but landfills have been banned in the EU since 2005. Incineration is less polluting and the heat can be used to generate electricity or heat. Next to the organic waste bins there are usually green bins where unwanted waste paper, newspapers, magazines, books, etc. are thrown away.

It should be noted, however, that cardboard boxes and cartons cannot be thrown in. Because they belong to the recyclable packaging, should be thrown into the special yellow plastic bag. Chinese people who have just arrived in Germany are often unaware of this. These plastic bags with the recycling symbol can be obtained free of charge from the nearest post office or supermarket. Other recyclable packaging such as can shells, plastic boxes, etc. can be put into this bag regardless of the material as long as the recycling logo is printed.

Every supermarket in Germany has a box for collecting used batteries. Glass bottles and jars are thrown into different garbage cans according to their color. Usually glass bins in groups of three, the box is marked with a conspicuous color sign: brown, green, transparent colorless, reminding you not to throw the wrong.

We won't come back if we do it a second time

The vast majority of the German public is supportive of Germany's cumbersome waste sorting. I have a friend who studied at the University of Dresden, and he said that when he first came to Germany, he lived in a student apartment, and because he didn't have the habit of doing so at home, he mixed his garbage into one piece and threw it out. One day, he saw the dormitory manager wearing gloves to open his discarded garbage bag and re-sort it, which made him very shocked and ashamed.

Fail to follow these rules and trouble will find you. Once, I worked in a garbage collection company, followed my colleagues to a neighborhood, a German colleague opened the yellow plastic bag indicating recyclable, and found a large ball of moldy flour inside, because the flour is too heavy, burst the plastic bag, spilled all over the floor, according to the rules, the flour should be put in a blue bag. Soon, the staff will be a warning sheet posted at the door of the district, to the following effect: your neighborhood people littering, made a mistake, now issued the first warning, if the second offense, we will not come back.

Listening to the Germans, once the second time, the garbage recycling company will " *** " to punish the whole district, the district management to spend a lot of energy to coordinate, so we are extra careful.

German cleaning workers wages, generally hourly for 12 euros / hour, a month there are about 3,000 euros, not lower than the office white-collar. (Source / "City Express")

5. garbage classification knowledge: after the classification of garbage where to go

Mr. cat in the intelligent garbage recycling equipment, we will be recyclables for the initial points and transported to the sorting center for the classification of baling, accumulated to a certain amount of unity docking to the renewable resources recycling enterprises for recycling; food waste to achieve the full green on-site conversion; other garbage is still into the existing Food waste is transformed into green waste; other waste continues to enter the existing sanitation transfer system and is processed through incineration or landfill; hazardous waste is transported to the hazardous waste storage point to ensure that it meets the relevant requirements of the environmental protection department. Hazardous waste will be collected once a week from each area and transferred to the hazardous waste storage point for subsequent transfer to the qualified terminal treatment unit.

6. Knowledge of garbage classification

In Japan, garbage is usually classified into 4 categories:
