Significance of Waste Paper Recycling
According to expert estimates,the use of one ton of waste paper to produce paper pulp 800 kg,equivalent to 3 m³ of wood pulp and paper savings,saving 1.2 tons of standard coal,saving 600 kw,water-saving 100 m³,can be less cut 17 large tree,saving 3 m³ of landfill space,it can also save more than half of the paper energy,35% less water pollution.
Summarized as follows:
1.Save raw materials and increase production
2.Reduce pollution,protect the environment
3.Save energy,reduce energy consumption,compared with wood pulp,less cost than chemical pulp
4.Saving investment,reduce the costs,only 25%-30% of the cost for chemical pulp.
Disadvantages:fiber recovery times are not unlimited,strength of the fiber will decrease.Recycling of paper types is limited,mainly newsprint,cardboard and etc.
