How many trees do I need to produce a pack of paper?

According toAccording to statistics, the global household paper is 100 million tons, of which China's household paper is 13.1 million tons. Maybe you don't have an idea of these tonnages. Then, if you convert it into raw materials, you will know how terrible the harm our tissue paper has caused to the environment!

It will take 4 20-year-old trees to produce one ton of paper. So, 1.28 billion trees are cut down every year, which is equivalent to 850,000 hectares of non-renewable trees cut down every yearPrimeval forestsChina alone will cut down 52.4 million trees, equivalent to 35,000 hectares of non-renewable primary forest every year. Think about it, the waste paper we use and throw away every day is a big tree that will grow for decades, and there is no sense of guilt.

In 1990, China's forest area was 100 million hectares. In recent years, with the improvement of environmental awareness, ** actively advocates environmental protection and takes action. In 2020, China's forest area increased to 100 million hectares.

Forests are an important resource for human survival, known as the "laws of nature" and "the lungs of the earth". It regulates the circulation of air and water in nature, affects climate change, protects the soil from wind and rain, and reduces the harm of environmental pollution to people. The survival of human beings is closely related to forests, and today, with the gradual increase of environmental awareness, people pay more attention to the protection, development and utilization of forests.

Saving paper has become an important topic of environmental protection, and with the vigorous promotion of the society and society, people's environmental awareness and conservation awareness are increasing. However, there is still an irreconcilable contradiction between the strong market demand and the serious environmental conditions, where people live on paper and cut down trees with paper. Technological innovation in the industry determines the ultimate direction of this environmental movement.

Fortunately, we have found the direction of victory. With the improvement of science and technology, the maturity of bamboo pulp and papermaking technology provides a new solution to the needs of human household paper. <>

Modern bamboo pulp and papermaking technology has made a huge technological breakthrough in 2014, and the quality and quality of household paper have been comparable to that of high-grade wood pulp paper. With the development of bamboo pulp and papermaking technology developed in recent years, bamboo paper is in ductility.

In terms of antibacterial properties, it is far superior to traditional wood paper。And most importantly,BambooWith the advantages of excellent regeneration and rapid growth, it has become the best raw material to stop, and the planned logging of bamboo in a certain proportion will accelerate the growth and spread of bamboo forests. "Replacing wood with bamboo" will become the mainstream trend of the paper industry in the future, and it is also the general trend of environmental protection.

If people use bamboo paper, 52.4 million trees could be saved in China this year, which is equivalent to contributing to the entire forest

Start by protecting forests and saving paper! The beginning of an eco-friendly and healthy life began with paper that replaced wood with bamboo! When buying tissue paper, taking a few seconds to pay attention to the raw materials can make a big contribution to our environment.

It takes about a small piece of tree to produce a pack of paper, because paper doesn't require too many raw materials.

It takes about 1 tree to produce a pack of paper, because the trunk of each big tree can be made into pulp, and the pulp content used in a pack of paper is very small.

A package of paper can be large and small, and a tree can be thick and thin. A4 paper can only be used as an example, and a pack of 500 sheets of A4 paper requires about cubic meters of wood.

It takes 3 cubic meters of wood to make one ton of paper, which is equivalent to more than 20 trees, so a pack of paper towels needs 1 kilogram of trees as raw materials.

A whole tree can make about 93,750 sheets of A4 paper.

A medium-sized pine tree (18 meters in diameter, 18 meters in height) weighs about 750 kilograms, and only half of its original weight (i.e. about 375 kilograms) is removed from the waste material to pulp the trunk for papermaking. Pulp is then turned into paper, and if 500 sheets of A4 paper weigh about 2 kilograms, then a whole tree can make about 93,750 sheets of A4 paper.

Here are some tips for saving paper in your daily life:

1. Blank paper, the front and back of the workbook can be written, drawn, calculated, etc., and the used paper can be used for origami, which is more economical.

2. If the origami is not folded well, it can be dismantled and folded again, not thrown away.

3. You can use towels to wipe your hands at home, and less napkins.

4. When you wipe your mouth with a napkin when eating out, try to use enough paper to reduce the number of sheets of paper.

5. Use a teacup for drinking water, not a disposable paper cup.

6. Waste newspapers and books can be wasted, don't throw them away casually.

7. Don't throw away the hard cardboard fragments, they can be used to decorate other things.

A large tree can make about 93,750 pieces of paper.

A tree can make 93,750 pieces of paper, which can be used by a total of 25 people, and China has a population of about 1.4 billion people, and uses 56 million trees every year.

In order to make paper, the trunk of the tree is pulped, and after the waste material is removed, only half of the original weight (i.e. about 375 catties) remains. Pulp is then turned into paper, and if 500 sheets of A4 paper weigh about 2 kilograms, then a tree can make about 93,750 sheets of paper.

One piece of paper is equal to 100 trees.

A 20-year-old tree can make 3,000 sheets of A4 paper, and if one person wastes one piece of paper, 1.3 billion people in China are 1.3 billion pieces of paper; 130000000 3000 equals 43333 trees.

How many trees do you cut down to produce a piece of paper? Heheda, if you look at the questioning method, you will know that the Holy Mother of the White Lotus is alive. I didn't expect the following answer to be so weak, one tree can produce so much paper.

A tree can make about 60 kilograms of paper.

A piece of paper only needs a little bark is enough, as long as you know how to solve it;

About 80,500 sheets.

It is difficult to come up with an accurate figure of how many sheets of paper can be made from a ton of wood, but the problem can be solved along the following lines: first, it is necessary to determine what kind of "tree" it is, and it can be assumed that most of the paper is made of pine trees.

Most pine trees have a diameter of about 0 3 meters and a height of about 18 meters, ignoring the gradual tapering of the tree body, then the volume of the tree is about 1 3 cubic meters: pi radius 2 length volume; 3．14＊0．152＊18＝1．3。

If there is a wooden board of 0 6 x 1 2 m, the plank weighs about 4 5 kg and has a volume of 0 008 m3; That is, the approximate weight of a pine tree is 730 kg (1 3 0 008 4 5).

In the paper production process, wood is processed into pulp. Its yield is about 50 – about half of the trees are knots, lignin and other components that cannot be used to make paper; That is to say, a pine tree can make about 365 kilograms of paper, and here is a reams (500 identical sheets of paper are called reams) for photocopiers, which has a total of 500 sheets of paper, weighing about 2,27 kilograms.

It is common to see the describal paper as "9 kg" or "11 kg" – this refers to the weight of 500 sheets of paper "17 x 22 in size). Thus, using this data, it can be calculated that a tree can make (365 2 27 500) 80,500 sheets of paper.

It takes two tonnes of dry wood chips or four tonnes of wood to produce one tonne of pulp, which is equivalent to 23 trees. Each ton of paper requires tons of wood, 300 tons of water, tons of coal, and 300 tons of waste water and a lot of exhaust gases. It is estimated that four trees with an average age of 20 years are cut down per ton of paper.

So, take care of your paper.

A ton of paper costs about 3-4 tons of wood, 300 tons of waste water and tons of coal.

A 20-year-old tree can make 3,000 sheets of A4 paper.

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

In the papermaking 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 high.

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.).

<> a 100-kilogram tree is made into more than 10,000 sheets of A4 copy paper that is commonly used. If the process is more complex or the paper is harder, the quantity will decrease.

Paper is not made of pure trees, because trees (usually trunks) are mostly made of wood fibers, which are harder and more durable, which is suitable for making hard paper, 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 used, so that the cost is lower than buying trees (wood), and the paper made is also high. One of the papermaking processes is the pounding of the treated material into a pulp.

Then it is condensed and solidified into paper in the mold, so that obvious, tougher or softer materials 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.

Each tree can produce 60 kilograms of paper, a pack of paper is 100 grams, and an ordinary tree can make about 600 packs of paper towels.

How to make a tree into paper:

1. The production of general printing paper is divided into two basic processes: pulping and papermaking. Pulping is to use mechanical methods, chemical methods or a combination of the two methods to dissociate plant fiber raw materials into colored pulp or bleached pulp. Papermaking is the combination of pulp fibers suspended in water through various processes to meet various requirements.

2. Paper mills generally need to store enough raw materials for 4 to 6 months, so that the raw materials can be naturally fermented in storage, so as to facilitate pulping and ensure the continuous production of paper mills.

3. Cut the raw materials such as reeds, wheat straw and wood into pieces or wood pieces through the material preparation section, and then put the small pieces of raw materials into the digester and add chemical liquid, and cook them with steam to boil the raw materials into pulp, or send the wood to the grinder to grind into pulp, or after a certain degree of cooking and then grinding into pulp.

4. Wash the pulp with a large amount of water, and remove the coarse flakes, knots, stones and sand in the pulp through screening and purification. Then, according to the requirements of the paper grade, the pulp is bleached to the required whiteness with bleach, and then the pulping equipment is used to pulp.

5. Add various auxiliary materials such as fillers, rubber materials, sizing agents and other accessories to improve the performance of paper in the pulp, purify and screen again, and finally send them to the paper machine to go through water filtration, pressing and dehydration, drying in the dryer, calendering and winding, and slitting and rewinding or cutting to produce web paper and flat paper. If the production is to produce coated printing paper, it needs to be realized by drying the middle part or producing it into a web paper and then coating it.
