在未來不飽和樹脂等下游產(chǎn)品需求接近飽和的情況下，新版限塑令有望推動可生物降解塑料行業(yè)的發(fā)展，可能為順酐的未來發(fā)展帶來一些積極的支持。
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.
據(jù)新聞報道，當局將于2008年6月實施超薄塑料袋的、銷售和使用禁令，這是11年來的修訂。生物降解塑料等產(chǎn)品將在新版限塑令下長期受益，或者得到政府的進一步支持，解決目前一次性塑料產(chǎn)品泛濫造成的日益嚴重的“白色污染”問題。
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細菌、霉菌(真菌)、藻類等引起的可降解塑料。丟棄后可被環(huán)境微生物徹底分解，真正實現(xiàn)對生態(tài)環(huán)境的零污染。隨著社會意識的增強,歐盟,美國,日本和其他發(fā)達和地區(qū)已經(jīng)制定法規(guī)限制或禁止使用一次性塑料制品,開發(fā)新的可降解材料,特別是歐洲議會3月28日,2019滑坡規(guī)定自2021年起將禁止歐盟使用水管,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.
據(jù)了解，可降解塑料按原料主要分為PLA、PBS、PCL、PHA、PHB等類型。其中，PBS (polybutanediol succinate)以其低廉的、優(yōu)異的機械性能、良好的加工性能和耐熱性在國內(nèi)外工業(yè)，已成為更有前途的通用可生物降解塑料之一。從原料上看，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過馬來酸酐的電解和加氫，兩者的單位消耗比接近1:1?？梢哉f，通過對琥珀酸的消費，開發(fā)PBS產(chǎn)品可以間接提高國內(nèi)外市場對馬來酸酐的需求。
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受到如技術(shù)不成熟,成本高,法律法規(guī)支持疲軟,企業(yè)融資困難的問題目前在國內(nèi)還沒有形成大規(guī)模的,以及的產(chǎn)品主要出口歐洲和美國等市場,和有限的支持上游琥珀酸和其他產(chǎn)品。卓創(chuàng)稱，到2019年，國內(nèi)從馬來酸酐中提取琥珀酸的商不足20家，如天津渤華中和和山東陽陽化工，總產(chǎn)能約為3萬噸。所以在2019年預測的消費結(jié)構(gòu)順丁烯二酸酐的下游,雖然含有酒石酸、蘋果酸、富馬酸、琥珀酸等產(chǎn)品的有機酸比例預計將達到13%,但只有2.7%的份額琥珀酸預計將附近,在順丁烯二酸酐的下游行業(yè)遠不飽和樹脂、酒石酸和其他產(chǎn)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.
但從長遠來看，隨著國內(nèi)經(jīng)濟逐步進入高質(zhì)量發(fā)展，人們的意識進一步增強，以PBS為代表的可生物降解產(chǎn)品越來越受到重視，政策支持力度也在加大。今年上半年,海南省的生態(tài)和環(huán)境率先發(fā)行的“規(guī)定禁止、銷售和使用一次性非降解塑料制品在海南經(jīng)濟特區(qū)”(草案)》,明確禁止、銷售和使用一次性非降解塑料制品在今年年底。Zhuochuang認為,通過引入“塑料塑性極限”的新版本,可生物降解的產(chǎn)品從政策可能進一步增加,這將間接給國內(nèi)順丁烯二酸酐市場帶來長期效益,和Zhuochuang將繼續(xù)跟蹤這個行業(yè)的發(fā)展,為您帶來及時、準確的行業(yè)參考。
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.
