1 manufacturing recycled paper
this is the most widely used way to use waste paper. It can be used not only to make recycled paper trays, but also to make recycled paper trays, firecrackers and so on. A French paper company has successfully developed a new process for newsprint recycling. This new process includes four processes: deinking, purification of paper fiber, absorption of ink and impurities, and then papermaking. The specific process is as follows: deinking technology is selected according to the type of ink; The paper fiber and soap deinking agent are sent into the deinking room composed of two chambers, so that the ink and impurities float to the surface with the foam and suck away with the suction device. The purified fiber pulp is concentrated to 15%, and the paper fiber is expanded by heating. It can also be bleached to give the luster of recycled paper; Finally, the high concentration pulp is sent to the papermaking equipment to make recycled paper with the same whiteness as the new paper
2 production of phenolic resin
Japan Prince paper company has successfully studied 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 the phenolic resin is higher than that of the product made from phenol and acetaldehyde, and the thermal deformation temperature is 10 ℃ higher than that of the previous phenolic resin
in production, old newspapers and office waste paper can be used as raw materials, but the cost of using office waste paper as raw materials is low, which is only half of that of using old newspapers
3 making household appliances
in Singapore and other places, people use waste paper raw materials such as old newspapers, old books and periodicals to roll into a round slender stick, wrapped with plastic paper, and manually weave carpets, cushions, bags, cat nests, door curtains, even tea tables, beds and other household appliances. When making, different patterns can be made according to different shapes of various household appliances, and then decorated with colors, so that the household appliances made are practical and beautiful
4 pressing glued cardboard
under the condition of 80 ℃, the scientific and technological personnel of former Czechoslovakia used five layers of waste paper and synthetic resin to press a kind of glued cardboard together, and its compressive strength is more than twice that of ordinary cardboard. The packing box made of this glued cardboard can use nails and screws, and can install bearing rollers. Its firmness is almost the same as that of the packing box made of plywood
5 moulded asphalt corrugated board
the scientific and technological personnel of the central Architectural Research Institute of India use waste paper, cotton yarn, coconut fiber and asphalt as raw materials to mould and press a new building material asphalt corrugated board. The asphalt corrugated board is used to cover the house, which has the advantages of good heat insulation performance, impermeability, portability, low cost, uneasy combustion and corrosion resistance
6 recover methane
experts from lundo University in Sweden beat waste paper into pulp, and then add an aqueous solution of anaerobic microorganisms that can decompose organic matter to the slurry; Then, it is transferred into the reaction furnace, and the cellulose, methanol and carbohydrates in the waste pulp liquid in the furnace are transformed into methane; The fuel methane can be obtained by removing the wood extract with enzyme
7 improve soil quality
in some pastures in Alabama, the soil is hardened and barren in some places. James Edwards, a soil expert in the state, used scrap paper and chicken manure to mix with the original soil to improve the soil quality of the pasture according to the characteristics that the waste paper will not decay and deteriorate quickly in the soil. The proportion is: 40% paper scraps, 10% chicken manure and 50% original soil. In this way, under the action of the base fertilizer bacteria in the chicken manure, the waste paper can rot and deteriorate rapidly, making the soil become soft and abnormal within 3 months. It is not only suitable for the production of forages and the vigorous growth of forages, but also can grow a variety of 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 land of pasture. If these lands are supplemented with new scrap paper and chicken manure in two years, the soil will become more fertile and loose
8 cultivating pleurotus ostreatus
British scientists and technicians cultivated Pleurotus ostreatus with waste paper and achieved high economic benefits. The specific method is: treat the waste paper into fragments, soak it in water for 72 hours, remove the printing and dyeing materials and dust, and then break up the small pieces of paper; Then, mix the waste paper with the cut Ma Yingdan according to 1:2, put it into the sterilized wooden shallow basin, which is generally 50x50x15 cm, and supply water and additional cellulose to the basin; After inoculating the bacteria, cover the wooden basin with plastic film and put it into the culture room at 25 ℃. After 34 days of mycelial development, the cover film can be removed and moved to the collection room at 20 ℃; After another 20 days of growth, mushrooms can be collected. Generally, it can be harvested continuously for 4 months, and each pot can harvest 1.5kg of mushrooms each time
9 is used as bedding in the corral
for a long time, people mostly use hay and saws as bedding in the corral. However, in recent years, the United States and Western European countries have replaced waste paper one after another. The effect of using waste paper as bedding in the fence is better in cattle farms, pig farms and chicken farms in Britain. In the broiler bar, waste paper scraps are paved from brooding to slaughter, and the average weight of each chicken can increase by 7.9%. For every 1000 broilers, only 192 kg of waste paper need to be padded. Compared with the traditional bedding hay and sawdust, waste paper scraps are relatively hygienic, do not contain poisons such as tannin in sawdust, and do not have residues of chemical insecticides common in rice straw and rice husk. At the same time, the moisture content is low and the heat insulation performance is better than other materials, which is especially suitable for the growth and development of chicks and newborn cubs
10 processed into cattle and sheep feed
countries such as the United States, Britain and Australia have developed a good method to process waste paper into cattle and sheep feed. Larry Berg, an animal nutritionist at Erie University in the United States, cut up the old newspaper, add water and 2% hydrochloric acid, and then boil it for 2 hours to decompose and break the cellulose under the action of high temperature and acid, and then add it into the feed to feed cattle and sheep. The proportion of addition is 20% ~ 40%. Cattle farms and sheep farms in the UK can feed cattle and sheep by cutting the waste paper into slender strips or kneading it into small paper balls, and then adding a small amount of nutrients. After eating, cattle and sheep can gain 1 /3 more weight than ordinary feed. Australian scientists smash the waste paper and mix it with an appropriate amount of linseed oil and honey to make it into pellet feed for cattle and sheep, which can make cattle and sheep grow fat and strong.
