The use of waste paper pulp meets the environmental protection requirements. The processing of wood and rice straw into pulp requires a large amount of industrial water consumption. Sewage discharge has become a bottleneck problem. The production of 1 ton of pulp, and the processing of wood and straw require 133 tons and 160 tons of industrial water, respectively, and the cost of sewage treatment remains high. The processing of waste paper into pulp only requires deinking, as long as 100 tons of industrial water, and only 0.5 yuan per ton of sewage can be managed into agricultural irrigation water, sewage treatment is simple.
Waste paper pulping can reduce production costs. If wheat straw (straw) is processed into 1 ton pulp, the production cost is about 3,000 yuan, and with wood pulp, the production cost is about 3,500 yuan, and the cost of processing with 8th waste paper into pulp is only about 1,500 yuan.
However, at present, China's waste paper purchasing operations are fragmented, and there are too many links, the classification is not fine, and the secondary price of waste paper is high, which affects recovery and utilization, and greatly increases the cost of the enterprise. To this end, experts suggest that with the economic development of our country and the improvement of people’s living standards, the amount of paper used will increase year by year, and the waste paper generated will also increase year by year. We will reform waste paper acquisition and management methods, implement industrialized operations, and improve the utilization of waste paper. Should mention the agenda:
——Can save a lot of foreign exchange. Calculating the annual paper consumption per capita of 400 million urban residents, the annual consumption of 10 million tons of paper is required. If we can increase the recovery rate by 20%, we can recover 2 million tons of waste paper, and calculate the foreign currency savings at 75 dollars per ton. 150 million U.S. dollars.
——Improve waste paper utilization, reduce wood and energy consumption. After industrialized management, waste paper can be categorized and sorted. A part of high-grade waste paper can be used to produce office business paper after adding a small amount of wood pulp to reduce wood consumption and protect forest resources. The use of waste paper as raw material for papermaking can save 2 cubic meters of wood, 400 kg of coal, 400 degrees of electricity, and 33 tons of water per ton of paper compared to the use of logs as raw materials.
- Save national and resident expenditures. After enterprises bid for garbage and purchase waste paper, waste disposal costs are borne by the company, and residents and the government can save on sanitation expenses.
-- It is possible to introduce competition mechanisms in the environmental hygiene industry to improve service efficiency. The implementation of industrialized waste paper management, first, the State Environmental Protection Administration, Technical Supervision Bureau has to specifically promulgate waste paper classification standards to meet the different needs and uses of waste paper manufacturers. The second is to increase propaganda, enhance residents' awareness of environmental protection, and consciously classify and store domestic garbage. Third, pilots can be conducted first in the sanitation treatment of government agencies and large and medium-sized enterprises, sum up experiences, and gradually promoted.
The latest survey results of Hangzhou Customs show that waste paper has unlimited business opportunities and has high social value and economic value. Since the reform and opening up, China's economy has developed rapidly, culture and education have flourished, demand for paper and paper products has increased dramatically, and a large amount of trees have been consumed. Since 1998, when China suffered a catastrophic flood, the country started natural forest protection projects. The supply of domestic wood pulp has tightened and prices have rebounded. The use of waste paper to replace wood pulp has been increasingly valued by companies.
