In recent years, China has more than 400 million tons of plastic packaging. Relevant departments predicted that in 2005 China's demand for plastic packaging materials will reach 5 million tons, is expected to produce 1.5 million tons of waste; China can cover plastic film, agricultural and sideline products such as fresh materials expected to reach 1 million tons; Daily miscellaneous goods and medical materials difficult to collect or not recycling needs of 100 million tons. A total of difficult to recover the use of plastic waste will reach 3.5 million tons, the resulting environmental problems will become increasingly serious. If 50% of the use of biodegradable plastic instead, then the demand for degradable plastics will reach 1.75 million tons, so biodegradable plastics in China has a greater market potential.

Now, the United States, Japan, Germany and other countries are vigorously developing degradable plastics this new environmentally friendly materials. Biodegradable plastics can be decomposed by microorganisms in the soil and can be decomposed into the natural environment and the human body. At present, most of the polylactic acid produced by corn is used as raw material.

From the current situation, the use of degradable plastics is the most in the traditional plastic products, such as packaging supplies and disposable production supplies. Also worthy of development of the market is a variety of daily necessities, stationery, toys, civil engineering supplies and medical plastic products.

Because these areas are currently entering fewer people, the market demand, high added value, especially in the country has begun to vigorously implement the desert control, barren hills and trees, urban planning and various slope protection, solid soil engineering, disposable plastic The use of products will be greatly increased, which is a good opportunity for degradation of plastics.
