How to effectively prevent the pollution of waste plastic film

How should waste mulch films be disposed of to effectively prevent pollution? Let’s analyze it together:

The recycling and management of residual film needs to focus on three links. First, mulch film manufacturers should produce degradable plastic mulch films, and at the same time produce mulch films with reliable quality, aging resistance, and thickness higher than 0.01 mm, so that mulch film covering can bring significant economic benefits to agricultural production. As the use of mulch films increases, At the same time, the development of mulch film production enterprises is promoted; the second is to promote the technology of film removal at the right time and the film side cultivation technology to recycle the residual film, reduce pollution, and ensure the sustainable development of mulch film covering; the third is to recycle the residual film and provide the residual film with Recycling brings direct economic benefits. The development of residual film recycling technology and the improvement of recycling rate can in turn promote the production of mulch film. These three links are interrelated and restrict each other. Ignoring any one of them will destroy the balance of the entire system and bring serious consequences.

1: Research and develop new materials and find alternatives to agricultural film. Practice has proved that only by developing new materials that are easily degradable and non-polluting can we eradicate plastic film pollution. The mulch films currently used are all polyethylene agricultural films, which are chemically stable and difficult to decompose and degrade, thus causing pollution to the soil environment. Therefore, the development of pollution-free and degradable biofilms should be encouraged to replace polyethylene agricultural films. At present, bioagricultural films are not strong enough or have high costs, making them difficult to promote. The performance of bioagricultural films should be further improved and optimized, and the cost should be gradually reduced to facilitate promotion and application.

2: Taking measures that combine manual and mechanical recycling can organize manpower and labor to recycle residual mulch film by hand or rake. It can also be recycled by using mulch recycling machine before plowing, leveling the land, sowing and after harvesting. Get better results.

3: Accelerate the formulation of economic policies related to the recycling of residual film. It is necessary to formulate some preferential policies to encourage enterprises that recycle, process and utilize waste agricultural film, fully mobilize their enthusiasm, and at the same time reflect the principle of "who pollutes, who controls" " principle requires mulch film sales departments and mulch film consumers to recycle and recycle it themselves.

4: Vigorously promote the technology of film removal at the right time. The so-called film removal technology at the right time refers to changing the film removal after crop harvest to the film removal before harvest, and screening out the film removal period of various crops. The specific time to remove the film is selected to be the first clear time after rain or when the soil is moist in the morning.

5: Optimize the farming system and further strengthen the stubble rotation system. Through the rotation of grain, vegetables and medicine, the average coverage rate per unit area of ??mulch film can be reduced, thereby reducing the pollution hazards of residual mulch film.

6: Strengthen publicity and guidance. The prevention and control of waste agricultural film pollution is a systematic project that requires the joint efforts, support and participation of all departments, industries and the broad masses of farmers. It is necessary to vigorously carry out publicity and education to raise the awareness of leaders at all levels and farmers about the long-term and serious harm of plastic film pollution, and to increase the consciousness of recycling waste agricultural film. At present, most farmers have realized the dangers of residual agricultural film and have begun to actively clean and collect it. However, the treatment methods are relatively simple. Apart from incineration and landfill, there is rarely centralized recycling and reuse. Due to the lack of a long-term mechanism, coupled with the large amount of mulch used and the wide range of pollution, there is still a large amount of mulch remaining in the land, which directly threatens the sustainable development of agriculture.
