The pollution of waste agricultural film is becoming more and more serious, and its recycling and reuse is an important part of the pilot work in the construction of "no waste city", and it is also a difficult problem in the field of solid waste disposal
It is understood that among the pilot projects, the Jinye family farm in Gaibei Town, Shangyu District has the largest area of 100 mu
According to Liu Weipeng, chairman of Shaoxing Greenstar New Materials Co.
, a biodegradable mulch R&D and industrialization enterprise and chairman of Shaoxing Greenstar New Materials Co.
, biodegradable mulch is made of aliphatic-aromatic copolyester, aliphatic polyester and other biodegradable products with complete biodegradability.
The polymer is the main component, and the agricultural ground cover film produced by blow molding and other processes replaces the ordinary polyethylene mulch film.
Under the action of microorganisms existing in nature, it is finally completely degraded into carbon dioxide, water and mineralized inorganic elements contained in it.
Salt, to avoid the adverse effects of ordinary PE plastic mulch residue damage to the soil structure and other adverse effects
Since some degradable plastic films are used for the first time, they may encounter the problem that the degradation of plastic films cannot meet the agricultural requirements
In terms of cost, the purchase cost of biodegradable plastic film is 50 yuan to 100 yuan per mu higher than that of PE plastic film, but the stubble of the biodegradable film can be directly ploughed, saving the labor cost of removing the film, and the overall cost is basically the same
"Experimental research in various places has proved that biodegradable film has a covering effect similar to that of ordinary plastic film, and can effectively reduce pollution to the agricultural environment
