Analysis of waste paper recycling industry

1 Waste paper has a wide range of renewable uses

with the development of economy and society, the use of paper is rising rapidly, and a large number of waste paper is produced. As the world's second largest consumer of paper and paperboard, China's paper consumption in 2003 was 48.06 million tons, and the recycling of waste paper was conservatively estimated at 14 million tons

the raw materials of paper are mainly wood, grass, reed, bamboo and other plant fibers. Waste paper is also known as "secondary fiber", and its main purpose is to reuse fibers to produce recycled paper products. According to the different fiber composition, recycling according to the paper type can maximize the value of waste paper resources

in addition to the production of recycled paper, waste paper with low quality or mixed with other materials has other extensive renewable uses: furniture production: Singapore and other places, roll waste paper such as old newspapers, old books and periodicals into a round slender rod, which is mainly reflected in the ball screw, electromechanical, sensor and other components wrapped with a layer of plastic paper to make practical and beautiful furniture

molded products: paper mold packaging products can be widely used in the internal packaging of products and can replace foamed plastics

daily necessities or special process supplies: waste paper that is difficult to deal with can be broken, ground, and molded after adding adhesives and various fillers to produce soap boxes, shoe boxes, sound insulation cardboard, and device paper

production of civil construction materials: mainly manufacturing thermal insulation materials or composite materials, plaster materials, etc

gardening and agricultural and animal husbandry production: waste paper is pulped and made into small flowerpots; Soil quality can be improved in agricultural and animal husbandry production, and can be processed into cattle and sheep feed (United States, Britain, Australia)

as fuel: Finland, Germany and Japan have done well in this regard

refining waste paper regeneration enzyme: after refining the regeneration enzyme, it can be used for waste paper deinking to produce white recycled paper

production of glucose: old newspapers are treated with acid and decomposed into glucose after dissolving the fiber

utilization in chemical industry: produce CMC, filter aid, and mix with synthetic fiber to produce industrial rags

2. Waste paper has become the most important raw material for papermaking

traditional papermaking using logs to make pulp consumes a lot of wood, destroys the ecosystem, and causes serious pollution. Therefore, the "urban papermaking" using waste paper has become the two development trends of modern paper industry together with the "Forest Pulp paper integration" integrating afforestation and papermaking. At the same time, urban papermaking also plays a role in eliminating urban garbage, reflecting the spirit of "urban production, urban consumption". Some developed cities have supporting urban waste paper recycling bases

the composition of waste paper in papermaking raw materials is increasing day by day. Experts predict that the proportion of waste paper in papermaking raw materials will be as high as 60% - 70% in this century. In 2003, waste paper has become the most important papermaking raw material in China (accounting for 49%). The value chain of China's paper industry is shown in Figure 1

3. The industrialization level of waste paper recycling in China is low

although the utilization rate (utilization/output) of waste paper in China is as high as 49%, the recovery rate (recovery/consumption) of waste paper is less than 30%. The import dependence of waste paper raw materials for papermaking in China has increased year by year, reaching 40% in 2003. The recovery rate of domestic waste paper has not been improved, and a large number of waste paper that is easy to recover and recycled is also processed into low-grade products such as cardboard and toilet paper by small enterprises with backward technology, which does not give play to the resource value of waste paper and also brings serious secondary pollution

the root cause of the low level of industrialization is that waste paper recycling not only carries out basic research, but also lacks industrial support policies, but the poor industrial foundation is also an important constraint. At present, an important bottleneck of domestic waste paper recycling is that waste paper raw materials are difficult to meet the requirements of papermaking enterprises in terms of quality and scale. In China, waste paper is simply divided into books, magazines, newspapers, cardboard, paper bags, white paper edges and so on. There is no unified standard, and it is transported in bulk from the distribution market of waste materials. The internationally standardized waste paper for commodity packaging has become a bulk trade commodity. There are 50 kinds of waste paper classification standards in the United States. In addition, China's papermaking raw materials straw pulp and wood pulp are mixed, and the raw fiber composition of waste paper is also difficult to compare with foreign wood pulp waste paper

in the absence of industry standards and unified supervision, China's waste paper recycling system is very fragmented, and it is difficult to have powerful large waste paper suppliers. Domestic waste paper is mixed and transported in small batches, which is difficult to meet the needs of large-scale production of paper enterprises. In order to pursue stable supply channels and raw material quality, it is inevitable for large and medium-sized paper enterprises to use imported waste paper as raw material

4. The development prospect of waste paper recycling in China is good

under the general situation of the shortage of papermaking raw materials and the increasing environmental protection requirements, China's waste paper recycling industry shows a good development trend, and the industrial prospect is bright

due to the strong demand brought by economic development, China's paper industry has developed rapidly. According to experts' prediction, China's paper demand will double in 2020, up to nearly 100 million tons. Before the adoption of a full set of product design and development, there was an overall shortage of papermaking raw materials, and the international waste paper price also rose all the way. As the scarcity of wood is difficult to solve in the short term, the shortage of waste paper raw materials will continue to exist for a long time. In this case, the value of domestic waste paper resources increases. Once the supporting policies, industry standards, technologies and other issues are solved, the domestic waste paper recycling industry is bound to become a new investment hotspot

whether it is the Tenth Five Year Plan for papermaking of the National Light Industry Bureau or the Tenth Five Year Plan of the national development and Reform Commission, the utilization of waste paper is the focus of development. With the gradual recognition of the social significance of waste paper recycling by all parties, the introduction of relevant policies and the formation of social atmosphere will be accelerated. At present, a number of enterprises engaged in domestic waste paper recycling have emerged
