In the future, when the demand of downstream products such as unsaturated resin is close to saturation, the new plastic restriction order is expected to promote the development of biodegradable plastics industry, which may bring some positive support for the future development of maleic anhydride.

　　据新闻报道，当局将于2008年6月实施超薄塑料袋的生产、销售和使用禁令，这是11年来的修订。生物降解塑料等产品将在新版限塑令下长期受益，或者得到政府的进一步支持，解决目前一次性塑料产品泛滥造成的日益严重的“白色污染”问题。

　　According to news reports, the ban on the production, sale and use of ultra-thin plastic bags will be implemented in June 2008, the first revision in 11 years. Environmental protection products such as biodegradable plastics will benefit from the new plastic restriction for a long time, or get further support from the government, to solve the growing problem of "white pollution" caused by the proliferation of disposable plastic products.

　　可降解塑料是由自然界微生物如细菌、霉菌(真菌)、藻类等引起的可降解塑料。丢弃后可被环境微生物彻底分解，真正实现对生态环境的零污染。随着社会意识的增强,欧盟,美国,日本和其他发达和地区已经制定法规限制或禁止使用一次性塑料制品,开发新的可降解材料,特别是欧洲议会3月28日,2019滑坡规定自2021年起将禁止欧盟使用水管,餐具和一次性塑料制品,如棉花花蕾。

　　Degradable plastics are degradable plastics caused by natural microorganisms such as bacteria, molds (fungi), algae, etc. After being discarded, it can be completely decomposed by environmental microorganisms, so as to realize zero pollution to the ecological environment. With the enhancement of social environmental protection awareness, EU, US, Japan and other developed countries and regions have formulated laws and regulations to restrict or prohibit the use of disposable plastic products and develop new degradable materials, especially the European Parliament's March 28, 2019 landslide regulation will completely prohibit EU countries from using water pipes, tableware and disposable plastic products, such as cotton flower buds, from 2021.

　　据了解，可降解塑料按原料主要分为PLA、PBS、PCL、PHA、PHB等类型。其中，PBS (polybutanediol succinate)以其低廉的、优异的机械性能、良好的加工性能和耐热性在国内外工业生产，已成为更有前途的通用可生物降解塑料之一。从原料上看，PBS主要由丁二醇和琥珀酸合成的聚酯制成，其中琥珀酸占近70%。目前琥珀酸的加工主要是通过马来酸酐的电解和加氢，两者的单位消耗比接近1:1。可以说，通过对琥珀酸的消费，开发PBS产品可以间接提高国内外市场对马来酸酐的需求。

　　It is understood that degradable plastics are mainly divided into PLA, PBS, PCL, PHA, PHB and other types according to raw materials. PBS has become one of the most promising general biodegradable plastics because of its low price, excellent mechanical properties, good processability and heat resistance. In terms of raw materials, PBS is mainly made of polyester synthesized by butanediol and succinic acid, of which succinic acid accounts for nearly 70%. At present, succinic acid is mainly processed by electrolysis and hydrogenation of maleic anhydride, and the unit consumption ratio of the two is close to 1:1. It can be said that through the consumption of succinic acid, the development of PBS products can indirectly improve the domestic and foreign market demand for maleic anhydride.

　　但由于可生物降解的塑料制品如PBS受到如技术不成熟,成本高,法律法规支持疲软,生产企业融资困难的问题目前在国内还没有形成大规模的生产,以及生产的产品主要出口欧洲和美国等市场,和有限的支持上游琥珀酸和其他产品。卓创称，到2019年，国内从马来酸酐中提取琥珀酸的生产商不足20家，如天津渤华中和和山东阳阳化工，总产能约为3万吨。所以在2019年预测的消费结构顺丁烯二酸酐的下游,虽然含有酒石酸、苹果酸、富马酸、琥珀酸等产品的有机酸比例预计将达到13%,但只有2.7%的份额琥珀酸预计将附近,在顺丁烯二酸酐的下游行业远不饱和树脂、酒石酸和其他产品。

　　However, due to the fact that biodegradable plastic products such as PBS are subject to immature technology, high cost, weak legal and regulatory support, the financing difficulties of production enterprises have not yet formed large-scale production in China, and the products are mainly exported to Europe and the United States and other markets, and limited support for upstream succinic acid and other products. Zhuo Chuang said that by 2019, there were less than 20 domestic producers of succinic acid extracted from maleic anhydride, such as Tianjin Bohua Zhonghe and Shandong Yangyang chemical, with a total capacity of about 30000 tons. Therefore, in the downstream of the predicted consumption structure of maleic anhydride in 2019, although the proportion of organic acids containing tartaric acid, malic acid, fumaric acid, succinic acid and other products is expected to reach 13%, only 2.7% of the share of succinic acid is expected to be nearby, and the downstream industry of maleic anhydride is far from unsaturated resin, tartaric acid and other products.

　　但从长远来看，随着国内经济逐步进入高质量发展，人们的意识进一步增强，以PBS为代表的可生物降解产品越来越受到重视，政策支持力度也在加大。今年上半年,海南省的生态和环境率先发行的“规定禁止生产、销售和使用一次性非降解塑料制品在海南经济特区”(草案)》,明确禁止生产、销售和使用一次性非降解塑料制品在今年年底。Zhuochuang认为,通过引入“塑料塑性极限”的新版本,可生物降解的产品从政策可能进一步增加,这将间接给国内顺丁烯二酸酐市场带来长期效益,和Zhuochuang将继续跟踪这个行业的发展,为您带来及时、准确的行业参考。

　　But in the long run, with the domestic economy gradually entering into high-quality development, people's awareness of environmental protection is further enhanced, and the biodegradable products represented by PBS are more and more valued, and the policy support is also increasing. In the first half of this year, Hainan's ecology and environment took the lead in issuing the draft of "prohibiting the production, sale and use of disposable non degradable plastic products in Hainan Special Economic Zone" (Draft), which explicitly prohibits the production, sale and use of disposable non degradable plastic products by the end of this year. According to zhuochuang, through the introduction of a new version of "plastic plasticity limit", biodegradable products may be further increased from policy, which will indirectly bring long-term benefits to domestic maleic anhydride market, and zhuochuang will continue to track the development of this industry, bringing you timely and accurate industry reference.
