生物可降解塑料是一种在特定时刻范围内经过细菌和其他微生物降解环境中的聚合物的。依据Markets & Markets 咨询公司发布的《2015-2020年全球生物降解塑料类型及使用的商场预测报告》,生物降解塑料商场从2015年到2020年,将以年均复合增长率10.8%的速度微弱增长,产量将从2015年的20亿美元增加到2020年的34亿美元。

Biodegradable plastics are polymers that are degraded by bacteria and other microorganisms in a specific time range. According to the Markets & Markets Consulting Company's Global Markets Forecast Report on the Types and Use of Biodegradable Plastics in the Market from 2015 to 2020, the market of biodegradable plastics will grow slightly at a compound annual growth rate of 10.8% from 2015 to 2020, and its output will increase from $2 billion in 2015 to $3.4 billion in 2020.
报告表明,就数量而言,聚乳酸(PLA) 因其优胜的力学性能和易加工的特点,成为生物可降解塑料商场的主力军,占有45.1%的商场份额,并将在所有生物可降解塑料类型中以比较快的速度持续增长。但在商场价值方面,淀粉共混物因其较高的出产成本,略胜聚乳酸。
The report shows that, in terms of quantity, polylactic acid (PLA) has become the main force of biodegradable plastics market because of its excellent mechanical properties and easy processing characteristics, accounting for 45.1% of the market share, and will continue to grow at the fastest rate in all types of biodegradable plastics. However, in terms of market value, starch blends are slightly better than polylactic acid because of their higher production costs.
目前Natureworks出产的生物可降解塑料Ingeo的使用范围,现已逐步从食品包装、软包装、卡片扩展到耐用品。大约2-3年前,Natureworks开始对Ingeo的特性进行研讨,发现它也能够适用于耐用品,甚至能够替代ABS或聚苯乙烯。
可降解颗粒
At present, Ingeo, a biodegradable plastic produced by Natureworks, has been gradually extended from food packaging, soft packaging, cards to durable goods. About two to three years ago, Natureworks began to study Ingeo's characteristics and found that it could also be applied to durables, or even replace ABS or polystyrene.
新的Ingeo配方将“耐高温”惯例化,经过结晶到达所需功能性,而且新配方中的可再生碳含量将到达90%,其冲击力和模量均得到了优化,这使它们更适合于注塑使用——特别是哪些目前适用ABS有着耐高温性能与高耐冲击强度和或高模量要求的产品。相对于ABS,其弯曲模量可提高达50%,让产品轻薄化成为可能。此外,适用于耐用品的Ingeo也具有更好的耐化学性。
The new Ingeo formulation routinizes "high temperature resistance" to achieve the required functionality through crystallization, and the renewable carbon content in the new formulation will reach 90%. Its impact force and modulus are optimized, which makes them more suitable for injection moulding use - especially those products currently suitable for ABS with high temperature resistance and high impact strength or high modulus requirements. Compared with ABS, the bending modulus of ABS can be increased by up to 50%, which makes it possible to make the product lighter and thinner. In addition, Ingeo, which is suitable for durable goods, has better chemical resistance.
直接从大气提取碳作为原材料
Direct extraction of carbon from the atmosphere as raw material
前Ingeo首要的原材料首要从玉米淀粉中提取葡萄糖,为提高产品性能,降低出产成本,Natureworks也可能会考虑将甘蔗作为原材料,将在东南亚甘蔗产量丰富的区域建筑新工厂。未来3-5年,将从秸秆、木屑、柳枝稷或稻草中提出木质纤维素,进而提取糖分。
In order to improve product performance and reduce production costs, Natureworks may also consider sugarcane as a raw material to build new factories in regions with rich sugarcane production in Southeast Asia. In the next 3-5 years, lignocellulose will be extracted from straw, sawdust, switchgrass or rice straw to extract sugar.
“咱们还做出斗胆假定,是否能够绕过植物这个中介,直接提取大气中的碳作为原材料为此,咱们与和Calysta公司进行研制协作,经过发酵进程,将再生生物基甲烷转化成乳酸,作为Ingeo的结构单体。这一技能目前仍处于实验研讨阶段,预计将于2-3年后完成基本的研制作业,3-5年后进行中试出产。若能完成甲烷到乳酸的转换,将为塑料职业带来革命性的打破。从废水处理、垃圾填埋场、农业废料分解以及厌氧消化这些活动中发生的可再生来历甲烷将成为提取Ingeo结构单体的原材料来历,不仅可更好完成可持续发展,而且将使PLA更具有价格竞争优势。”
"We also made the bold assumption that we could bypass the intermediary of plants and directly extract carbon from the atmosphere as raw materials. To this end, we cooperated with Catalysta in the development of a fermentation process to convert regenerated bio-based methane into lactic acid as Ingeo's structural monomer. This skill is still in the stage of experimental discussion. It is expected that the basic research and development work will be completed in 2-3 years and pilot production will be carried out in 3-5 years. If the conversion of methane to lactic acid can be completed, it will bring a revolutionary breakthrough to the plastic industry. The renewable origin of methane from wastewater treatment, landfill, agricultural waste decomposition and anaerobic digestion will be the source of raw materials for extracting Ingeo structural monomers. It will not only achieve sustainable development better, but also make PLA more competitive in price.
将生物甲烷转化成乳酸,不仅仅是技能的斗胆革新,还将有用削减温室气体的排放,削减碳脚印。而在刚刚曩昔的9月,我国主席习近平在对美国进行国务访问期间,也宣布我国将于2017年启动碳总量控制与交易系统(cap and trade system),这也将为我国生物可降解塑料带来发展契机。
Converting biomethane into lactic acid is not only a bold innovation in skills, but also a useful way to reduce greenhouse gas emissions and carbon footprints. In September, during his state visit to the United States, Chinese President Xi Jinping also announced that China will launch the cap and trade system in 2017, which will also bring opportunities for the development of biodegradable plastics in China.
