What handicrafts can waste paper be made into?

1. prepared a soup bowl with a plastic bag outside. The purpose of packing plastic bags is to prevent waste paper from sticking to the soup bowl when it sticks to paper in the future, so as to facilitate the final demoulding.

I bought a bottle of water-soluble glue specially for this handicraft, but later I learned in the group that people can actually use ordinary paste, which is a waste of money ... The treatment method is to cut or tear off the waste paper to be treated. At first, I just tore the waste paper into pieces of paper, glued it and stuck it outside the upside-down soup bowl.

Don't stop after wrapping the first floor. Before the glue dries, we will continue to glue the first layer with water, and then paste the second and third layers of waste paper. Outside, because we are not forced, we can tear the waste paper into pieces, so that the colors will be more diverse.

When it is almost thick enough, you can put it aside and wait for the glue to dry quietly. After removing the glue, we should be careful to tear off the soup bowl together with the plastic bag. You should pay great attention to demoulding.

3. There may be uneven tearing of paper on the inner surface of the torn paper bowl, which will expose white. It doesn't matter, we can continue to glue in it and paste several layers of waste paper to make up for the gap in that place. At this time, if you think the paper bowl can continue to thicken, stick it hard to make the bowl stronger.

It's good for every family to make a set of dishes for children, and it's also good for putting sundries at ordinary times. Don't worry about not using them in the future.

What products can waste paper be reused and processed into?

In daily life, waste paper is produced every day. If these waste papers are not collected and used, they will pollute the environment. If they are collected and comprehensively utilized, they can turn waste into treasure and become useful resources.

In order to make full use of waste paper resources and prevent environmental pollution, in recent years, countries all over the world attach great importance to the comprehensive utilization of waste paper and explore many ways of comprehensive utilization of waste paper.

1 manufacturing recycled paper

This is the most extensive way to use waste paper. It can be used not only to make recycled wrapping paper, but also to make recycled newsprint. A French paper company has successfully developed a new process of newsprint regeneration. This new process includes deinking, paper fiber purification, absorbing ink and impurities, and then making paper. The specific process is as follows: according to the type of ink, choose deinking technology; Sending paper fiber and ink deinking agent into a deinking chamber consisting of two chambers, so that ink and impurities float to the surface with foam and are sucked away by a suction device; Concentrate the purified fiber pulp to 15%, heat it to make the paper fiber expand, and bleach it to make the recycled paper have luster; Finally, the high-concentration pulp is sent to papermaking equipment, and recycled paper with the same whiteness as new paper can be made.

2 production of phenolic resin

Japan's Prince Paper Company has successfully developed a new technology of dissolving waste paper in phenol to produce phenolic resin. Because phenol is combined with low molecular weight cellulose and hemicellulose, the strength of phenolic resin is higher than that of products made of phenol and acetaldehyde, and the thermal deformation temperature is higher than that of previous phenolic resin 10℃.

In production, both old newspapers and office waste paper can be used as raw materials, but the cost of using office waste paper as raw materials is lower, only half of that of using old newspapers.

3 manufacturing household appliances

In Singapore and other places, people use old newspapers, old books and periodicals and other waste paper raw materials, roll them into round slender strips, wrap them with plastic paper, and manually weave carpets, cushions, bags, cat nests, door curtains, and even household appliances such as coffee tables and beds. When making, you can weave different patterns according to the different shapes of various household appliances, and then decorate them with colors, so that the household appliances made are practical and beautiful.

4 press bonded paperboard

At the temperature of 80℃, the former Czechoslovakian scientists made a glued paperboard with five layers of waste paper and synthetic resin, and its compressive strength was more than twice that of ordinary paperboard. The packing box made of this glued cardboard can use nails and screws and can be equipped with bearing rollers. Its firmness is almost the same as that of plywood packaging boxes.

5 Molded asphalt tile cold plate

The scientists and technicians of the Central Institute of Architecture in India used waste paper, cotton yarn ends, coconut fiber and asphalt as raw materials to mold a new type of building material asphalt corrugated board. Building with this kind of asphalt corrugated board has the characteristics of good heat insulation, good water tightness, portability, low cost, non-combustion and corrosion resistance.

6 methane recovery

Experts from Lundow University in Sweden beat waste paper into pulp, and then added an anaerobic microbial aqueous solution that can decompose organic matter into pulp. Then, it is moved into a reaction furnace, and cellulose, methanol and carbohydrates in the waste paper pulp are converted into methane; Then the wood extract is removed by enzyme, and the fuel methane can be obtained.

7. Improve soil quality

In some pastures in Alabama, USA, the soil in some places is hardened and nothing grows. James edwards, a soil expert in this state, used shredded waste paper and chicken manure to mix with original soil to improve the soil quality of pasture according to the fact that waste paper will not rot and deteriorate quickly in soil. Its proportion is: paper scraps 40%, chicken manure 10%, and original soil 50%. In this way, waste paper can quickly rot and deteriorate under the action of basic fertilizer bacteria in chicken manure, which makes the soil soft and abnormal within 3 months. It is not only suitable for producing pasture and making pasture grow vigorously, but also can plant many crops such as soybeans, cotton and vegetables, and the yield is quite high. At the same time, it will not have any side effects on the pasture. If new scraps of paper and chicken manure are added to these lands after two years, the soil will become more fertile and loose.

8 Pleurotus ostreatus cultivation

British scientific and technological personnel cultivated Pleurotus ostreatus with waste paper, and achieved high economic benefits. The specific method is as follows: waste paper is treated into powder, soaked in water for 72 hours, then printed matter and dust are removed, and then small pieces of paper are scattered; Then, the waste paper and the cut Mayingdan are mixed according to the ratio of 1: 2, and put into a sterilized wooden shallow basin, which is generally 50x50x 15cm, and water and extra cellulose are supplied to the basin; After inoculation, cover the wooden basin with plastic film, put it in a culture room at 25℃, remove the cover film and move it to a harvesting room at 20℃ after the mycelium develops for 34 days. & gt
