Plastic residue film ***es a threat to the environment to strengthen recycling is the right way

2022-06-22 16:24:59

At present, plastic residue film has posed a threat to the sustainable use of cultivated land. In order to curb white pollution, experts and grassroots people believe that the government should take the lead to improve the residue film recycling network, strengthen scientific research support simultaneously, and promote the treatment process.
The production of plastic film in China accounts for about 20% of the total production of plastic products, and is one of the fastest growing categories of plastic products. In terms of the application fields of plastic film (thickness of 0.06mm ~ 0.26mm) in China, packaging industry has the largest consumption, the largest variety and the most widely used, with its consumption accounting for about 2/3, followed by agriculture accounting for about 30%, and functional film, such as microporous film, shielding film, geomembrane and so on.
At present, due to the non-standard use of different thicknesses of plastic mulch, it is more difficult to recycle plastic mulch manually and promote mechanical picking up to some extent. Some experts suggest that the national standard of mulch thickness should be raised in time to allow ultra-thin mulch to exit the market. The relevant departments of the state should consider referring to foreign standards of plastic film, study and revise the national thickness standard of plastic film, and raise the current national minimum standard of the thickness of polyethylene blow molded agricultural ground cover plastic film to more than 0.01 mm.
The cost of mulch planting is getting higher and higher, using the national regulation of 0. 008 mm size mulch, one mu land needs about 3. 5 kilograms. Can cotton farmers in order to save production costs, a large number of use does not meet the national standard of 0. 005-0. 006 mm ultra-thin film, although one mu land can save 1 kg film, but thin film is easy to aging, which increases the difficulty of residual film recovery. Currently used polyethylene plastic mulch, buried in the soil for 200 years will not degrade.
Industry insiders suggest that credit support, land use, tax incentives and other policies should be formulated to support the development of waste agricultural film recycling and processing enterprises. On this basis, the government subsidies to mobilize the recycling enterprises to build network enthusiasm. Enterprises can be encouraged to set up extensive waste agricultural film recycling outlets in rural areas through development agreements to purchase large households and floating waste purchase merchants. To the scale of recycling, the scope of the expanding enterprises, the government should give appropriate incentives.
