Now let's look at those resources that are easy to slip through our fingers:
1. A new life in the wastebasket-discarded newspapers, notebooks and wrapping paper.
Recycling waste paper 1 ton can regenerate 800 kilograms of good paper, save trees 17 trees, save 3 cubic meters of landfill space, reduce 240 kilograms of soda ash, reduce 75% of pollution discharge in papermaking, save 40%-50% of energy consumption in papermaking, and each paper can be recycled at least twice. In addition, our daily discarded waste cloth can also be used for recycling paper.
At present, the recovery rate of waste paper in China is only 20-30%, and 6 million tons of waste paper are lost every year, which is equivalent to wasting1-30,000 mu of forest resources.
2. The headache of the government and the heart disease of environmental protection-plastic bags, plastic bottles, disposable plastic lunch boxes and tableware.
All waste plastics, waste lunch boxes, food bags, woven bags, soft packaging boxes, etc. It can be recycled into fuel by reducing waste plastics into gasoline and diesel oil; 1 ton of waste plastics can produce 700-750 liters of unleaded gasoline or diesel oil. Many waste plastics can also be reduced to recycled plastics, and the recycling times can reach ten times. Taking waste lunch boxes as an example, it can be made into high-quality super glue for building decoration after recycling; Three waste lunch boxes can make a ruler for students, and 20 waste lunch boxes can make a beautiful stationery pen container. From plastic flowerpots to park benches, we can use discarded lunch boxes as raw materials to produce them.
At present, the recovery rate of plastic bags in China is less than 10%, and most plastics can't be separated because they are mixed with other domestic garbage, which makes recyclable resources and non-recyclable resources buried together, causing great waste.
3. Broken glass bottles and pieces of glass can still be restored.
Recycling waste glass can not only save natural resources, but also reduce energy consumption by about 32%, air pollution by 20% and water pollution by 50%. Recycling 1 ton of waste glass saves 20% of the cost compared with using new raw materials. The benefits of recycling one ton of waste glass to the environment and resources are: 720kg of quartz sand, 250kg of soda ash, 60kg of feldspar powder, 0/0t of coal/kloc and 400 kwh of electricity can be saved.
The energy saved by recycling a glass bottle can keep the light bulb on for 4 hours. Unfortunately, at present, the recycling rate of waste glass in China has not exceeded 10%. The reason is that glass is mixed with other garbage, and the cost of separation far exceeds the economic value of recycling.
The so-called rubbish in people's hands-cans, tin cans, waste batteries.
After the waste cans are dissolved, they can be recycled 100% for countless times to make new cans, and can also be made into parts of cars, planes and even furniture. Recycling aluminum cans can save 95% of the energy needed for new aluminum cans and reduce 95% of air pollution. Discarding an aluminum can is equivalent to wasting half of the oil in the aluminum can. Mercury and cadmium contained in waste batteries are toxic heavy metals with high pollution, but rare metals such as zinc, copper and manganese dioxide can be extracted from recycled batteries.
At present, the iron products recycling industry in China is quite developed. With the cooperation of professionals, the recycling rate of iron products is above 60%, but the recycling of used batteries is not optimistic. Because the battery contains toxic metals, its recovery and storage need certain conditions, which makes some economically underdeveloped areas have "no place to send the battery".
5. Ancient times are also a kind of glory-deciduous weeds, vegetable roots, chicken intestines and fish bellies, and eggshell scales are used for making.
More than 40% of the garbage we throw out from home every day is kitchen waste such as peels, eggshells, vegetable leaves and leftovers, which can be treated as organic fertilizer or feed by composting and fermentation. This has become a great wealth in the vast rural areas of China. Biogas produced by the fermentation of these "garbage" can save a lot of energy, and the money saved for purchasing energy will be put into production, resulting in new benefits.
Why do we find the use value in garbage, but we can't use it reasonably? At present, the value of usable but unused waste in China reaches 25 billion yuan every year, and about 3 million tons of scrap steel and 6 million tons of waste paper are not recycled. The recovery rate of waste plastics is less than 3%, and the recovery rate of rubber is 3 1%. It can be said that most of them are wasted for the following reasons:
1. Not every company can realize the significance of garbage disposal and have the technical conditions for garbage disposal, which makes the garbage disposal technology only in the hands of a few companies and fails to achieve the effect of popularization and development.
2. Most of the garbage at present is mixed garbage, and many wastes are mixed in a pool, which causes great inconvenience to extract favorable resources, greatly increases the cost and is more difficult to popularize.
If the garbage can be classified and discarded, it will bring great convenience to the treatment company, and the popularization and development of garbage treatment will not be difficult. The earth is our common home and its environment depends on us to protect it. If we can cherish every resource on the earth and recycle it as much as possible, then the treasure of the earth will not be hollowed out, and we can have a beautiful and clean earth! We are looking forward to it! We work hard.
