Advanced technology & subsidy policy to ensure agricultural recovery enhances unceasingly

Advanced technology & subsidy policy to ensure agricultural constantly improve the recovery of the advanced technology & amp; River subsidy policies to ensure the recovery improve

the emergence of agricultural plastic film is called a white revolution in the history of the agriculture, it is not only beneficial to crop yield and improving labor production efficiency, also provides a new method for agricultural products in storage. Along with gradually increasing of demand and agricultural production in our country, the amount of waste polluting plastics is growing, and its recovery rate is not high.

as of early 2012, our country agricultural agricultural output reached 124. 50000 tons. Agricultural film recovery is only 50%, which means nearly half mulching films are not recycled. According to typical field film residue monitoring, gansu province, according to the results of all monitoring block has a different degree of the membrane. Residua from 5 per acre. 23 kg - 14. 67 kilograms.

1, the recycling status quo of our country agricultural

waste polluting plastics recycling in China are mainly composed of artificial collecting, mechanical recovery rate less than 20%, the reason has the following several aspects:

mulching films of low cost, recovery efficiency is relatively low.

the fields of different cultivation way of recycling waste membrane mechanical requirements, mechanical regional adaptability is poorer.

the farmers do not realize waste agricultural residues in the field of serious damage to the

the government's supervision and support is not enough, not the correct boot on waste polluting plastics recycling.

according to relevant data shows: a person recycling waste polluting plastics need 7 - an acre of land Eight days. So the farmer took the film to decay or burning on the spot.

2, recycling of agricultural waste, processing

the way farmers basically treat waste film has the following kinds: reuse, buried and recycling.

use again: is to continue the secondary use of waste of agricultural film, film quality is relatively good agricultural films can achieve the dual purpose, or a film is multi-purpose. With the development of agricultural new technology, reusable river broad market space.

be buried: the way of handling and simple, but pollution is very serious.

recycling: can effectively save resources, protect the environment, is the ideal way to

recycling technology burning

the recycling heat recovery efficiency is low, and the high cost of collection, storage, burning tail gas pollution problem is very serious.

high temperature cracking of the spent mulching films for high temperature cracking reaction, recycling monomer and the mixed oil low molecule. This approach has the advantage of resource utilization. Defect is complicated, high technical requirements, investment is large, the utilization rate is low, Japan is high temperature pyrolysis technology is one of the developed countries. Regeneration granulation

will be abandoned heating, plasticizing and polluting plastics extrusion granulation, and then continue to manufacture products. Waste PE agricultural film preparation of recycled aggregate, can be still used for production of agricultural film, can also be used to make fertilizer bags, garbage bags, agricultural renewable water pipe, fences, trees, POTS, barrels, dustbin, geotechnical material, etc. PVC agricultural film regeneration aggregate can be used to produce heavy bags, agricultural water pipes, sole and other products.

3, the present problem plastic recycling distribution

recycling branch processing enterprises regional unbalanced development, some local resistance, the remote is still in the recycle blind area, at the same time, some places great leading enterprises established scale, and there do not have enough to eat.

ultrathin membrane is difficult to effectively put an end to the

ultra-thin plastic recycling is difficult. Ultrathin film aging fast, easily broken, artificial pick up clean up or mechanical collecting all difficult, barely clearing the remnant membrane fragments area is small, generally with the root crop, soil mixed together. There is almost no the value of recycling use.

some countermeasures to strengthen financial support, support the development of breeding processing enterprises

since 2011, by the ministry of environmental protection in gansu province as the second batch of national rural environment shall punish demonstration province, one of in recent years, in the pilot area, gansu province, trying to establish the farmland residual film recycling and utilization system, and gradually form farmers pick up - Node recovery - Enterprise processing three links to support each other. Mutual constraint waste polluting plastics recycling network. The project achieved significant effect. Now gansu films recovery rate reached 100%, recovery rate of membrane has nearly two-thirds.

subsidies directly to farmers for ultra-thin plastic recycling rare problems: the thickness of the river at present our country has developed a standard, in order to avoid increase the burden on farmers, should formulate fiscal subsidies. For farmers to use standard subsidise the cost of membrane increases. From the source to ensure farmland residual film recyclability. Conversion table packaging printing knowledge
