Centennial is not degradable "plastic agriculture" unsustainable

Before and after the harvest of spring crops , often in rural China staged a spectacular sight: the whole family bent over picking the residue in the soil Shimoda plastic mulch .

Due to thermal moisturizing , covering the crop transparent plastic mulch can increase production, but it brought a flood of white pollution .

Deputies , chairman of the German environmental technology company Guangdong Yi Wang Hui group interpret their " recommendations on strengthening agricultural film plastic pollution prevention , the promotion of sustainable agricultural development " ( hereinafter referred to as " " recommended " " ) to the 21st Century Business Herald reporter , the proposed national promotion biodegradable mulch instead of plastic sheeting .

According to " China Agricultural Statistics" estimates, in 2010 , the national annual sales of agricultural plastic film 1.184 million tons , covering an area of ​​3.5 million hectares , is expected to 2015 , plastic agricultural film demand will increase to 1.3 million tons , covering an area of up to about 4 million acres .

But with the rising amount of use , the plastic sheeting can improve crop production began to lead to cuts .

Xinjiang Academy of Agricultural Reclamation regional comparison test showed that when the average residual amount of 77.9kg · ha of land , 167.6kg · ha , 279.0kg · ha and 372.2kg · ha , cotton production rates were 3.82% , 7.45% , 11.71% and 18.92% . Conclusion Xinjiang Academy of Agricultural Reclamation given that cotton production is a major factor in the residual plastic sheeting, plastic film residue increases , the magnitude of cotton production have exacerbated the trend .

Resources and Regional Planning Institute, Chinese Academy of Agricultural Sciences , deputy director Ren Heaven , said: " Farmland " white pollution " problem is more prominent to be solved ."

In fact , the farmers also know that harm the plastic sheeting , but even the family picking up plastic sheeting old Richie battle , and even hug film using professional rake , roll film roll , they can only collect plastic film land surface, and can collect up to about 30%.Sellotape


After seeing plastic sheeting because of excessive residues resulting in Xinjiang 2,000 acres of land no longer the case after planting , Wang Hui group recommends promoting the use of biodegradable alternative to plastic mulch sheeting .

"Proposal " State support and encourage scientific research departments , corporate research and development of new non-polluting biodegradable material , the use of natural products and agricultural products as raw materials to produce biodegradable agricultural films , including the use of cassava starch as raw material for the production of biodegradable agricultural films .

" An effective way to cure plastic pollution is agricultural plastic film material selection , or other similar crops with cassava starch extracted production of plastic sheeting , you can use within 12 months after the 100% degradation into organic fertilizers ." Wang Hui group told the 21st Century Business Herald reporters , "This plastic sheeting with industrial production technology has the condition . recommends that national development and reform, agriculture and other departments to develop research programs and support measures to promote the comprehensive promotion ."Washi tape


It is reported that the whole biological downgrade already developed technology as early as the advent of plastic sheeting in 2007 , the German environmental benefits such as Guangdong produced full-starch plastic sheeting, disposable tableware, baby supplies. However , the promotion of biodegradable plastic sheeting to use , there are still policy and market obstacles.Masking tape


"There is no policy to support this environmentally friendly products , " Wang Hui group told the 21st Century Business Herald reporter : the emerging industry, " " Twelfth Five-Year Plan " referred to include new material, but there is no landing policy ."

Wang Hui group believes that the country 's industrial policy apparently did not keep up with the pace of industrial innovation . "Full and full of biodegradable starch products is currently no national standards, but still a continuation of the relevant standard plastic products ."Wholesale masking tape
