Rapid increase in packaging materials, the environment to bring much pressure? Huge. 'Ordinary plastic artificial polymer structure, so far the environment of microorganisms can not be rapidly degraded polymers, into the natural environment after a hundred or two years can not be degraded, The impact on the environment is irreversible.'Ruan Wenquan, professor at the College of Environmental and Civil Engineering, Jiangnan University revealed that Wuxi is a logistics distribution center, Wuxi 's courier business growth in the forefront of this' double eleven' period of this year may be some express to Wuxi But also for secondary packaging, packaging garbage throughout the growing volume of Wuxi.More troubling is that the lack of appropriate recovery of plastic packaging recycling channels, most of them mixed with domestic waste disposal, some were burned, while a small part of the landfill.
Express packaging is not non-plastic? No. Jin Zhengyu introduction, he developed biological new material is starch-based biodegradable plastic, the main component is corn starch. Corn starch is a natural polymer, plastic is also a polymer, can use starch grade Biodegradable plastic instead of ordinary plastic.Biodegradable plastic composting, even if incineration, the carbon emissions is only one-third of ordinary plastic, the resulting toxic substances is much less.It is reported that this new material has long been successful Enter the market, the product has biodegradable lunch boxes, plastic bags, etc., by some catering takeaway electricity use, accounting for the national plastic packaging over 20% of the market.Moreover, this product has shown a supply shortage trend, and Jin Zhengyu cooperation manufacturers The newly built production base in northeast China will be put into operation by the end of next year, with an annual output of 40,000 tons of starch-grade biodegradable plastics.
Cost is a major consideration, then the new material is expensive? Basic starch plastic equivalent to ordinary plastics .Zheng Zhengyu said that the current price of less than 3,000 tons of a ton of starch, while a ton of plastic needs tens of thousands of yuan, now promote biodegradable organisms Plastic 'stumbling block' is not a price, but a cost of time The equipment used to shape starch-based materials is tailor-made and it takes time to expand the production scale.
Today, online shopping has become a new consumer habits, many people and Liu Mengling, after the online shopping do not know how to deal with express packaging, only flushed.Ruan Wenquan Professor said that packaging rubbish, especially plastic garbage once into the natural world, Will bring a variety of negative effects, if the carton packaging and kitchen waste mixed together, it will reduce the resource recycling rate .He appealed, we must do garbage classification, with little action to protect the ecological home.
