Wastepaper

 

paper and cardboard products that have been used; also the paper waste products of printing shops, mills producing office paper supplies, and the like. Wastepaper is used at paper mills as a secondary raw material.

After preliminary cleaning, the wastepaper supplied to paper and cardboard mills is made into fibrous pulp (slurry). The pulp is then cleaned, concentrated, and sent to a cardboard or paper machine.

The recycling of wastepaper is very important for the economy: wood is saved and the cost of the finished product is lowered. Wastepaper is 1.5-2.5 times less expensive than conventional wood pulp. One ton of utilized wastepaper saves approximately 4 cu m of wood. The wastepaper reclaimed in some countries (such as the Netherlands, Japan, and the Federal Republic of Germany) accounts for 50 percent of the total quantity of required paper production.
