  资源与环境是人类在21世纪完成的可持续开展所面临的严重问题,生物技术将成为解这一问题的关键技术之一。其在形成环境污染的诸多要素中,塑料废弃物形成的公害已惹起了社会的普遍关注。

  Resources and environment are serious problems facing the sustainable development of human beings in the 21st century, and biotechnology will become one of the key technologies to solve this problem. Among the many factors that cause environmental pollution, the pollution caused by plastic waste has aroused widespread concern in society.
  目前世界上主要消费的降解资料国度有美国、日本、德国、意大利、以色列和加拿大等等国度,种类有光降解、光-生物降解、崩坏性生物降解、完整生物降解等等类型。
  At present, the main countries consuming degradation data in the world are the United States, Japan, Germany, Italy, Israel and Canada, and the types are photodegradation, photobiodegradation, disintegration biodegradation, complete biodegradation and so on.
  淀粉生物降解颗粒指在土壤中能被微生物合成的塑料,借助于细菌或其水解酵素能将资料合成为二氧化碳、水、蜂巢状多孔的材质和盐类,它们进一步经过微生物作用后可彻底合成,重新进入生物圈,是当前各国研讨与开发的热点。因而,生物降解塑料普通指具有一定的机械强度、并能在自然环境中全部或局部被(微生物如细菌、霉菌和藻类)合成而不形成环境污染的新型塑料。生物降解的机理主要由细菌或其水解酶将高分子量的聚合物合成成小分子量的碎片,然后进一步被细菌合成为二氧化碳和水等物质。
  Starch biodegradable granules refer to plastics that can be synthesized by microorganisms in the soil. With the help of bacteria or their hydrolytic enzymes, they can be synthesized into carbon dioxide, water and honeycomb-like porous materials and salts. They can be thoroughly synthesized after further microbial action and re-enter the biosphere. They are currently studied and developed by various countries. Hotspot. Therefore, biodegradable plastics generally refer to new plastics which have certain mechanical strength and can be synthesized by microorganisms such as bacteria, fungi and algae in the natural environment wholly or partially without forming environmental pollution. The mechanism of biodegradation is that bacteria or their hydrolases synthesize high molecular weight polymers into small molecular weight fragments, which are then further synthesized into carbon dioxide and water by bacteria.
  关于生物降解资料,目前已开发作产出多种产品:
  With regard to biodegradable data, a variety of products have been developed and produced:
  其一,降解树脂与母料包括全生物降解树脂、光-生物双降解母料和复合降解母料等。
  First, degradable resins and masterbatches include biodegradable resins, photobiodegradable masterbatches and composite degradable masterbatches.
  其二,降解塑料制品包括堆肥袋、渣滓袋、购物袋、电子包装袋、地膜、餐饮用具、高尔夫球钉和发泡资料等。
生物降解颗粒
  Secondly, degradable plastic products include compost bags, waste bags, shopping bags, electronic packaging bags, plastic film, catering utensils, Golf tacks and foam materials.
  其三,普通塑料制品包括购物袋、渣滓袋和办公用品等。
  Third, ordinary plastic products include shopping bags, waste bags and office supplies.
  我国生物降解塑料主要应用在农业、食品包装、降解发泡网和一次性快餐盒等方面。
  Biodegradable plastics are mainly used in agriculture, food packaging, degradable foam mesh and disposable fast food boxes in China.
  农业塑料薄膜农膜属农业消费上三大支柱产品(化肥、农药、农膜),原属国度专控产品,市场上不断较紧俏。自1979年以来,农膜掩盖栽培技术在我国得到了鼎力推行,1980年农膜掩盖面积仅为2.5万亩,到1992年达5000万亩。农膜的应用范畴从最初的棉花、蔬菜,开展到经济作物,如花生、瓜果、甜菜、甘蔗、烟草、水果和粮食作物水稻、早稻、小麦、玉米等的栽培。农用薄膜的推行和提高获得了明显的经济效益,据统计,1982年-1987年农膜带来的增产效益为71亿元;1978年-1989年地膜掩盖栽培技术累计增产280亿公斤粮食和经济作物的增长,从上述统计数字中能够看到,推行应用农膜带来的十分显著的经济效益。
  Agricultural plastic film is one of the three pillars of agricultural consumption (fertilizer, pesticide, agricultural film), which is originally a country-controlled product and is constantly in demand in the market. Since 1979, the cultivation technology of agricultural film covering has been vigorously implemented in China. In 1980, the area of agricultural film covering was only 25,000 mu, and in 1992 it reached 50 million mu. The application of agricultural film ranges from cotton and vegetables to cash crops, such as peanut, melon and fruit, beet, sugarcane, tobacco, fruit and grain crops, rice, early rice, wheat and maize. Obvious economic benefits have been obtained from the implementation and improvement of agricultural film. According to statistics, the yield-increasing benefits of agricultural film from 1982 to 1987 are 7.1 billion yuan. From 1978 to 1989, the cumulative production of 28 billion kg of grain and economic crops increased by plastic film covering cultivation techniques. From the above statistics, we can see that the application of agricultural film has brought about a great deal. Significant economic benefits.
  总之,降解塑料最突出的优点是可降解,不污染环境,它替代聚乙烯等塑料已是开展的必然趋向,塑料薄膜产品的晋级换代也是势在必行。据预测,目前这一市场范围达300亿元,且每年以30%-50%的速度增长。
  In a word, the most prominent advantage of degradable plastics is degradability and not polluting the environment. It is an inevitable trend to replace polyethylene and other plastics. It is imperative to upgrade plastic film products. According to the forecast, the current market scope reaches 30 billion yuan, and the annual growth rate is 30% - 50%.
