  资源与环境是21世纪人类可持续发展面临的主要问题。生物技术将成为解决这一问题的关键技术之一。在造成环境污染的诸多因素中,塑料垃圾引起的公害引起了社会的广泛关注。

  Resources and environment are the main problems facing the sustainable development of human beings in the 21st century. Biotechnology will become one of the key technologies to solve this problem. Among the many factors causing environmental pollution, the pollution caused by plastic waste has attracted wide attention of the society.
  目前,世界上降解材料的主要生产国有美国、日本、德国、意大利、以色列、加拿大等,品种有光降解、光生物降解、崩解生物降解、完全生物降解等。
  At present, the main producers of biodegradable materials in the world are the United States, Japan, Germany, Italy, Israel, Canada and so on. The varieties include photodegradation, photobiodegradation, disintegration biodegradation, complete biodegradation and so on.
生物降解颗粒
  淀粉生物降解材料是指塑料可以在土壤微生物、细菌或其水解酶的帮助下可以材料分解成二氧化碳和水,蜂窝状多孔材料和盐,他们进一步彻底微生物分解后,回生物圈,是当前研究和开发的热点。因此,生物降解塑料一般是指在自然环境(细菌、霉菌、藻类等微生物)中,具有一定机械强度,能够完全或部分降解而不污染环境的新型塑料。生物降解机理主要是由高分子量聚合物被细菌或其水解酶分解成小分子量片段,再被细菌分解成二氧化碳、水等物质。
  Starch biodegradable materials refer to plastics that can be decomposed into carbon dioxide and water, honeycomb porous materials and salts with the help of soil microorganisms, bacteria or their hydrolytic enzymes. After further complete microbial decomposition, they return to the biosphere, which is the current research and development hotspot. Therefore, biodegradable plastics generally refer to new plastics with certain mechanical strength in the natural environment (bacteria, fungi, algae and other microorganisms), which can completely or partially degrade without polluting the environment. The biodegradation mechanism is that high molecular weight polymers are decomposed into small molecular weight fragments by bacteria or their hydrolytic enzymes, and then decomposed into carbon dioxide, water and other substances by bacteria.
  关于可生物降解材料,已经开发和生产了各种产品:
  With regard to biodegradable materials, various products have been developed and produced:
  首先,降解树脂和亲本材料包括全生物降解树脂、光生物双降解亲本材料和复合降解亲本材料。
  Firstly, degradable resins and parent materials include all-biodegradable resins, photobiodegradable parent materials and composite degradable parent materials.
  二是可降解塑料产品包括堆肥袋、垃圾袋、购物袋、电子包装袋、塑料薄膜、餐饮用具、高尔夫球钉、泡沫材料等。
  Two, biodegradable plastic products include compost bags, garbage bags, shopping bags, electronic packaging bags, plastic films, dining utensils, golf balls, foam materials, etc.
  第三,常见的塑料产品包括购物袋、垃圾袋和办公用品。
  Third, common plastic products include shopping bags, garbage bags and office supplies.
  我国的生物降解塑料主要用于农业、食品包装、降解泡沫网和一次性快餐盒。
  Biodegradable plastics are mainly used in agriculture, food packaging, degrading foam nets and disposable snack boxes.
  农膜是农业生产上的三大支柱产品(化肥、农药、农膜),原控制产品,市场一直比较紧张。1979年以来,我国大力推广农业覆膜栽培技术。1980年,农膜覆盖面积仅2.5万亩,1992年达到5000万亩。农业膜的应用领域从比较初的棉花、蔬菜,发展到经济作物,如花生、甜瓜、甜菜、甘蔗、烟草、水果和粮食作物,如水稻、早稻、小麦、玉米等的种植。据统计,1982年至1987年,农业电影增产效益达71亿元。从1978年到1989年,塑料薄膜覆盖的种植技术累计增加粮食和经济作物280亿公斤,从以上统计数据可以看出,农业薄膜的推广应用带来了非常显著的经济效益。
  Agricultural film is the three pillars of agricultural production (fertilizer, pesticide, agricultural film), the original state control products, the market has been relatively tight. Since 1979, China has vigorously promoted agricultural film mulching cultivation techniques. In 1980, agricultural film covered only 25,000 mu, reaching 50 million mu in 1992. The application of agricultural film has developed from cotton and vegetables to cash crops, such as peanut, melon, beet, sugarcane, tobacco, fruit and grain crops, such as rice, early rice, wheat and maize. According to statistics, from 1982 to 1987, the output of agricultural films increased by 7.1 billion yuan. From 1978 to 1989, the planting technology covered with plastic film increased grain and cash crops by 28 billion kg. From the above statistics, it can be seen that the popularization and application of agricultural film has brought remarkable economic benefits.
  总之,可降解塑料比较突出的优点是它们是可降解的,不污染环境。取代聚乙烯等塑料是大势所趋,塑料薄膜产品的升级换代也势在必行。据估计,目前的市场规模为300亿元,年增长率为30%至50%。
  In short, the most prominent advantage of degradable plastics is that they are degradable and do not pollute the environment. Replacing polyethylene and other plastics is the general trend, and upgrading of plastic film products is imperative. It is estimated that the current market size is 30 billion yuan, with an annual growth rate of 30% to 50%.
