How much pencil paper can be made from a big tree

14. Use less wooden pencils and more mechanical pencils.

Some developed countries have come to see the manufacture of wooden pencils as a "sunset industry" and have begun to produce only mechanical pencils.

15. Make full use of white paper and try to use recycled paper.

The used side of the paper can be turned over to make scratch paper and note paper. Refuse to accept those propaganda materials that are distributed everywhere, the production of these propaganda materials will not only waste a lot of paper, but also destroy the city's appearance and hygiene because of the distribution and posting everywhere. Recycled paper is produced from waste paper.

One ton of waste paper = 800 kg of recycled paper = 17 trees.

In many countries, the use of recycled paper has become fashionable, and people take pride in showing a phrase printed with the phrase "made of recycled paper" to show their environmental awareness and civility.

Sort the cycle and regain the old tradition of waste products.

"It's not new to us. I remember when I was a child, saving three toothpaste skins could be exchanged for a sugar cake; Orange peels are dried and can be sold to pharmacies; Waste cloth heads, waste ink bottles, etc. can be reused. Not only does garbage not cause environmental disaster, but it also provides raw materials for society.

Now, we're making it a habit to mix garbage.

You must know that garbage mixing is to treat garbage as waste, and garbage sorting is to treat garbage as a resource; The mixed garbage is sent to the landfill, which encroaches on a large amount of land, and the garbage is distributed to various ** recycling departments, which do not occupy land; Mixed garbage, whether landfilled or incinerated, will pollute the land and atmosphere, while separate garbage will promote harmless treatment; Mixed garbage increases the work of the sanitation and environmental protection departments, and the separation of garbage only requires our efforts. The main raw material for the production of disposable chopsticks is wood, and the wood consumed to make disposable chopsticks every year is a huge waste. Processing a tree that has grown for 20 years into wooden blocks and then into finished products can only make more than 10,000 pairs of chopsticks, and the effective utilization rate of wood is only about 60%.

Each restaurant consumes about 150 pairs of disposable chopsticks a day on average, which means that each restaurant has to "eat" a 20-year-old tree in more than two months, which is undoubtedly an amazing waste loophole. In addition, the production process of disposable chopsticks is very simple, and many companies do not have a sterilization process. In packaging, transportation, and storage, there are no strict hygiene requirements, which increases the chance of germs spreading.

I don't know if it helps you!

Paper is generally not made of pure trees, because trees (usually trunks) are mostly composed of wood fibers, which are harder and more durable, which is suitable for making paper with high hardness, but it is definitely not something that can be done by just one tree.

In the paper industry, bark, waste paper (the first part of the paper), rags and other raw materials with good toughness are generally used, so that the cost is lower than buying trees (wood), and the paper made is also the best one.

One of the papermaking processes is to mash the treated material into a slurry and then solidify it into paper in a mold, so obviously, the tougher or softer material will have an advantage (wear and tear of mold equipment, etc.).

The hardness of the paper determines the proportion of materials used in papermaking, and the harder the paper, the higher the wood fiber content.

Furthermore, it depends on what kind of tree it is, different trees and different densities determine the value of a tree, which is commonly known as "gold content", and the trees of the soft tropical broad-leaved forest are much inferior to the trees of the tall coniferous forests in the cold zone.

In addition, the size and volume of the tree also determine the content of fibers, large trees and small trees, American giant shirts, and the age of the trees.

Therefore, the specific number of sheets of paper that a tree can make is determined by both the tree and the paper.

Every time we sharpen the pencil and cut off the tree, it turns out that since we went to school, we have begun to cut down indiscriminately.
