Biodegradable bags promotion why frequently blocked?

Speaking of plastic bags, you must not unfamiliar, it already is closely connected with our life, along with the use of plastic bags, plastic garbage pollution problem increasingly prominent, launched in 2008 in China plastic limit, and run for nearly 10 years, plastic limit to little effect, degradable garbage bags in such a case it was a good solution to plastic garbage pollution. So why its promotion process has been blocked, slow progress? The author thinks that there are three reasons: first, the technologies of biodegradable plastics in our country to carry out early, degradable garbage bags products also is varied, have fish in troubled waters, has false attention-seeker, does have its effect also have the complex market environment, product quality good and bad are intermingled, bad so many consumer identification, there is no lack of being deceived, to say the early years of undesirable businessman shooting themselves in the foot, will originally to mess up a good market environment, make consumers once bitten by snakes once bitten, twice shy. Second, consumer groups lacking environmental consciousness, the national environmental pollution problems in recent years, environmental protection has been hot topic, the environmental protection consciousness, but group consciousness is not enough. Biodegradable bags with environmental attribute, and this property is difficult to perceive, most people believe that pay for the environmental protection, in a short period of time don't get results, do not think long, so in the eyes of ordinary plastic bags inherent value to measure environmental protection biodegradable property of substitutes, so don't think this kind of consumption is worth. Third, biodegradable technology cost is high, plastic degradation problem has always been one of the major difficulty in the scientific community, the current mainstream degradation technique has two kinds, one is plastic degradation technology, realization of polyethylene accelerate the degradation of natural environment, the second is to use the biological base of raw materials to replace traditional ethylene base material. Two technical route are the mainstream market, at present the main problem is that the cost problem, day strong environmental protection double degradable plastics technology due to the use of base material for polyethylene backing material, technical compatibility is good, no equipment modification, so is the low cost of degradable plastics technology on the market, even if is such, as compared with ordinary plastic products the price is two times as much, so the market acceptance is low.
