Waste paper ** reuse has always been advocated by people, we sell waste newspapers and books are waste paper After being transported to the paper mill, the pulp is broken up again through a hydraulic pulper (something like a big washing machine) and then impurities are removed, including plastic skins, staples, etc., and then deinking and then bleaching to get pulp that can produce paper That's probably it.
Pulp molding is a three-dimensional papermaking technology. It uses waste paper as raw material and shapes paper products into a certain shape by special molds on a molding machine. It has four major advantages:
The raw materials are waste paper, including board paper, waste carton paper, waste white edge paper, etc., which is widely used; The production process is completed by pulping, adsorption molding, drying and shaping, which is harmless to the environment; It can be recycled; The volume is smaller than that of foamed plastic, which can be overlapped and convenient for transportation. Pulp molding, in addition to lunch boxes, tableware, more industrial cushioning packaging, is currently developing very rapidly.
Including egg trays, fruit trays. It is made of waste paper as raw material, adding some chemicals, and then made into various shapes of model products according to different uses, which are used as packaging liners for eggs, fruits, precision devices, fragile and fragile glass, ceramic products, handicrafts, etc., with good cushioning and protection performance. The production of pulp molding technology and equipment has developed rapidly, and the basic process is three processes: slurry preparation, molding and drying.

Recycled paper is a kind of paper produced from waste paper as raw material through more than a dozen processes such as sorting, purification, pulping, and copying, which is a major measure to protect the environment and save resources.
One ton of waste paper can produce 850 kg of recycled paper with good quality, save 3 cubic meters of wood, save 100 cubic meters of water at the same time, save 300 kg of chemical raw materials in recycled paper notebooks, save tons of coal, and save 600 degrees of electricity. Relevant data show that China's paper consumption is about 35 million tons per year, and the waste paper that can be used every year is more than 10 million tons. Relevant information shows that the city is one of the cities with the largest demand for paper in the country, with an annual demand of at least 3.5 million tons of office paper and printing paper.
Today, when the whole society is calling for environmental protection, if all these papers are made of recycled paper, it will save 10.5 million cubic meters of wood, equivalent to 7.7 million acres of natural forests (or 3.85 million plantations).
Circular economy is to carry out the overall design of production, transportation, consumption and waste treatment in accordance with ecological laws, and use high-tech means to realize the reduction of resources and the recycling of waste. The end point of the one-way operation mode of resource production and consumption waste is turned into a secondary resource. It is conducive to shaping the urban spirit with the characteristics of the times.
**Taking the lead in using recycling to promote the renewal of social consumption concepts is to advocate resource awareness, environmental awareness, and cultivate the recycled paper market in the whole society.
Greenpeace calculates that using 1 tonne of 100% recycled paper reduces CO2 emissions by tonnes compared to using 1 tonne of all-wood pulp paper. Natural sewage capacity: 100 tonnes (wood pulp) to 400 tonnes (straw pulp) is required to produce 1 ton of pulp, and most of this wastewater is discharged.
The aerobic organic compounds emitted by China's paper industry account for more than 30% of the country's total emissions. Black liquor pollution is the most severe from papermaking, with 10 tonnes of black liquor emitted for every 1 ton of pulp produced. The country will produce 100 million tons of black liquor throughout the year.
China's paper industry is facing a serious shortage of pulp, and a large number of imports are needed every year. If these used waste paper can be reasonably and effectively utilized, less raw wood pulp, and the production of recycled paper, then it can not only relieve the pressure of insufficient pulp, but also protect our original forest resources. Forest resources are limited, and it is not a cornucopia that cannot be emptied.
For paper companies, the production of recycled paper from waste paper is a recyclable process. Our paper companies should consider the production of recycled paper as the direction of future development, and find their own source of wealth in this "waste paper forest".

Because the raw material of paper is trees, if waste paper is used to produce recycled paper, it can reduce the felling of trees, save resources, protect trees, protect the environment, and also make paper recycled and reduce environmental pollution.
-
Waste reuse, resource conservation, reduction of tree felling, environmental protection, reduction of energy consumption, and the production of recycled paper from waste paper have the above 5 benefits.
-
It can save resources, protect trees, protect the environment, and regenerate the earth's resources, which is conducive to the benefit of future generations of mankind.
-
It can save costs, protect the environment, recycle resources, reduce environmental pollution, and reduce environmental protection treatment costs.

Summary. Hello, glad for your question. Personally, I think that so, it must be counted, waste paper is an important fiber raw material for pulp and papermaking, waste paper should also be pulped or dissolved through hydraulic pulping, and then paper-based machine papermaking processes such as impurities, screening, deinking, bleaching, washing and so on.
Hope it helps! I wish you a happy life and a happy day.
Does waste paper count as pulp and paper?
Wait a minute, I'm looking up the information, wait a minute, I'm sorry for you.

Summary. There are many types of pulp: softwood pulp, hardwood pulp, cotton pulp, hemp pulp, straw pulp, reed pulp, etc., and these pulps can be divided into many kinds such as wood pulp is divided into grinding wood pulp, semi-chemical pulp, chemical pulp, etc., straw pulp and wheat straw pulp, straw pulp, dragon beard straw pulp, etc., papermaking is generally mixed with more than two kinds of pulp to ensure that the quality is met and there is an ideal cost, namely:
Most of the paper is mixed pulp, and it's hard to say if there is a waste pulp component in the toilet paper you're talking about.

Summary. 2. Use waste paper pulp to make paper cans. Throw the unused waste paper into a large container, pour water to soak it softly, and then tear and stir the wet paper to become a slimy pulp.
Find a smooth surface as a simple mold, beat the pulp evenly on it, and then remove the whole to dry, and then make a paper can, paper bucket or paper cone.
How can waste paper be reused and what can be made of? How much investment is required for pulping waste paper and reproducing corrugated paper.

Making recycled paperRecycled paper is one of the most important ways to use waste paper, not only to make it into packaging recycled paper, but also to make it into recycled newsprint, which not only protects the environment, but also reduces the cutting of trees and other HPE resources required for papermaking.

How can waste paper be reused and what can be made of? How much investment is required for pulping waste paper and reproducing corrugated paper.
1. The best fiber papermaking used in Lihuai can greatly reduce the consumption of forests, water, reeds and pollutants. According to experts, one ton of waste paper can produce tons of recycled paper fiber, which can cut down 17 trees and save 3 cubic meters of landfill space.
The use of waste refers to the fact that the organs of the organism will become developed if they are used regularly, and they will gradually degenerate if they are not used regularly, and the same is true from the perspective of evolution, the more organs are used, the more powerful they will evolve.
