In the process of dry farming in our province, the plastic film has played an important role, especially the popularization and application of the technology of furrow sowing on the whole film, which will find a new breakthrough for the development of dry farming in our province.
However, how to strike a balance between promoting agricultural development and protecting the environment and eliminating "white pollution" in the use of plastic film has also become a major challenge Gansu must face. In recent years, the province has continuously strengthened prevention and control of agricultural non-point source pollution , Vigorously carry out the action of plastic sheeting recovery, the initial formation of 'plastic film production increase income, the old film recycling, resources turning waste into treasure, agricultural recycling development', successfully out of a waste plastic film prevention and control of pollution.
Strengthen the source of pollution prevention and control
Yuzhong County is one of the largest film counties in our province, the use of plastic film throughout the county's 23 towns and villages 268 administrative villages' annual use of plastic film in the county up to 3,000 tons, 1 kg of dry and dry areas of new film can produce 3 kg Waste film, Kawansha 1 kg of new film can produce 5 kg of waste film, the county can produce more than 10,000 tons of waste film each year. 'Yuzhong Agricultural Ecology Environmental Protection Management Station Manager Zhang Guangquan introduced.
A large number of discarded plastic sheeting were randomly piled on the ground in front of the houses, scattered in the grass, mountain beams and gully, not only destroying the natural landscape but also seriously affecting the rural environmental hygiene. Facing this situation, Yuzhong County actively carried out waste plastic sheeting Recycling, and strengthen white pollution control training and advocacy to guide farmers to use agricultural plastic sheeting scientifically to promote a dual-use film and mechanized pick-up film technology to prohibit the use of ultra-thin plastic film with a thickness of less than 0.008mm in the whole county to reduce the difficulty of picking up waste plastic film .
Although it is cheaper and cheaper to use, the ultra-thin film is less effective in preserving soil moisture and picking up difficulties and is likely to cause pollution. Therefore, the acceptance of the public is very high during the promotion of high-standard film mills.
In 2013, our province included the recycling of discarded plastic sheeting in the responsibility system for environmental protection throughout the province, banning the production, sale and use of agricultural film with a thickness of less than 0.008mm across the province and formulated specific penalties for irregularities Provincial Department of Agriculture, Animal Husbandry, Industry and Commerce, Quality Supervision and other departments also jointly established a new mechanism to jointly promote the prevention and control of plastic film pollution and crack down on the production, distribution and use of ultra-thin plastic film and inferior plastic film within the province.
Provincial Department of agriculture and animal husbandry will waste plastic sheeting into the work of agriculture and animal husbandry departments involved in the target responsibility book signed, requiring all levels of agriculture and animal husbandry departments to seriously implement the guidance of waste plastic sheeting and supervision of the regulatory responsibility for the work is not effective, the responsibility is not implemented In place, the film residue in farmland prominent areas, public exposure and the necessary administrative accountability.This series of measures to make the province's pollution control film residue onto the legal and standardized track.
In order to strengthen the prevention and control of the residual pollution of waste agricultural plastic film, the province took the lead in the introduction of local laws and standards to promote high standards of plastic film production.Zhang Guangquan think that the use of high standard plastic film, although the input cost per unit area has increased, Thickness, weathering, tensile strength and other indicators of the impact of film recovery, the basic can be done after the full recovery.
On November 9, dozens of film-mulching machines were running at high speed in Jin Ya Town, Jinzhu Plastic Products Co., Ltd. in Yuzhong County, where workers are busy packing high-end mulch products. , We have adopted the technology of producing static electricity and adding auxiliary agents such as ultraviolet ray blocking agent and anti-oxidant etc. This kind of mulch film has high service life, can reduce the amount of soil adhesion, is conducive to the later period recovery, and improves the processing and utilization rate after recovery Jin Xinhai, head of the company said.
Establish and improve the recovery system
In Yuzhong County town of Shitou ditch village plastic film recycling station on the wall, a piece of green and white 'old plastic film recycling approach' sign particularly noteworthy, said: 'Every pay 2 kg of waste plastic sheeting Can enjoy 1 kilogram of new film financial subsidies, not to pay the old plastic sheeting shall not enjoy financial subsidies ... ... '
'This' trade-in 'approach is one of the measures we have taken to improve farmers' enthusiasm for the recovery of discarded agricultural plastic sheeting, and the county has also utilized special funds from the state's discarded agricultural plastic sheeting to intensify financial subsidies. Every 6,000 yuan In exchange for 1 kg of new film, 'site technician Liu Taitai said:' These measures have reduced the farmers' cost of planting and enhanced their awareness of environmental protection. After the Autumn Harvest, villagers took the initiative to pick up the old film and transport it To the site in exchange for a new film '.
Liu too too is a local villager stone ditches, home has more than 20 acres of dry land, mainly in the planting of corn, wheat-based. 'I planted 10 acres of corn this year, with 8 acres per mu membrane, according to market price, buy the film needs 960 Yuan, but after participating in the waste plastic film TM, the plastic film investment reduced to more than half of the original. '
Wushan County is also a major county with film, covering an area of about 316,000 mu annually, the use of mulch has reached 1,896 tons, and the usage of greenhouse film has reached 1,100 tons. The local waste plastic film recycling outlets in 15 townships A, according to per kilogram of waste film 1.6 yuan and every 7 kilograms of old film for 1 kg of new film recovery of two ways to mobilize the masses to mobilize the enthusiasm of discarded plastic sheeting to improve recycling of waste plastic sheeting outlets. Last year, the county A total of 1490 tons of waste film recycling, recycling rate of 78.5% or more.
In 2011, the province took the lead in setting up a special fund for the recycling of waste agricultural plastic sheets at the provincial level in China, accumulating a total of 136 million yuan of funds. It has adopted the method of 'financial subsidies, The basic coverage of the province's main film area with the processing enterprises and recycling outlets.
Up to the end of last year, the province has supported and led 285 enterprises of all kinds engaged in the recycling of waste plastic film, set up 2,100 recycle outlets in villages and villages, used waste plastic film recycling enterprises as a link, and promoted the recovery of brokers, mobile traders or In remote areas set up a fixed recovery outlets and other means to market the way the acquisition of waste plastic sheeting, the formation of a 'peasants picked up sales, the acquisition of traders, recycling outlets, business processing and utilization' market-oriented recycling system.
Expand recycling space
Waste plastic film processing and utilization of enterprises is the effective convergence of the use of plastic film, picking up the recycling, resource utilization of the three links of the core link, was vividly as waste plastic sheeting 'digestive tract.' Our province to support processing enterprises bigger and stronger, enterprises With the government, farmers work together to expand the film recycling channels, and thus efforts to cure film pollution.
In Lanzhou Xin Tong Rubber Products Co., Ltd. plant, after the fall of this year, after the recovery of the site of the transport of waste plastic film piled up, 'This is the recent recovery from the various towns and villages of waste film, after shredding, cleaning, hot melt Will once again become the raw material of plastic products, can produce polyethylene pipes, plastic containers, drip tape and other products. 'The company official said.
Provincial Agricultural Environmental Protection Station, deputy director Li Chongxiao said that the province of waste plastic film processing and utilization of the two main ways, one is the recycling of waste plastic film for the production of recycled plastic particles, with recycled particles for further processing, this approach is widely used Dry farming in the central and eastern regions.One is the direct recovery of waste plastic film directly, mixing a certain percentage of slag, processing wells under the water wells, manhole covers, urban greenery and other renewable products, such as tree grate, this approach mostly in Hexi Irrigation Area use.
In order to avoid pollution of waste plastic sheeting without secondary pollution, our province requires waste plastic sheeting processing and utilization of enterprises in the production line design, supporting the installation of waste smoke collection and processing equipment, the construction of multi-stage sedimentation wastewater recycling ponds, production The process of waste gas, waste water harmless treatment, so that waste plastic film processing and use of the adverse impact on the environment to a minimum.At present, this advanced technology, large-scale production methods is the province of waste plastic recycling of resources The main push direction.
The province has also made it clear that enterprises enjoying capital support should implement the responsibility system of package recycling and strictly implement the agreement on the recovery of used agricultural plastic film for the area covered by the bid invitation and purchase and explore the establishment of 'Who Who Produce and Who Recycle' Production responsibility extended system. Last year alone, the province recycled a total of more than 140,000 tons of waste plastic film, recycling rate of 78.6%.
