开发生物基橡胶是未来全球橡胶业可持续发展的唯一途径。国外领先的轮胎企业以及一些大型合成橡胶生产企业已经把开发生物基橡胶和生物基橡胶单体列入发展规划，并在积极付诸实施。我国不失时机地启动了杜仲胶产业化的推动工作，在保障我国橡胶工业的可持续发展和减少化石能源橡胶材料比例的战略部署中迈出了重要一步。自2010年以来，在国家有关部委和中国橡胶工业协会的大力推动下，国内涌现了一批投身杜仲产业开发的企业。2011年4月份，国家发改委发布的"产业结构调整目录(2011本)"中，首次将"杜仲种植生产"和"新型天然橡胶的开发和应用"列入鼓励类目录中，并于当年对部分有杜仲产业基础的企业实施了资金扶持。2011年6月份，国家发改委、科技部、工信部、商务部和国家知识产权局联合发布的《当前优先发展的高技术产业化重点领域指南(2011年度)》中将杜仲橡胶生产技术及装备列入"新材料"项。

上半年，生产资料市场相对疲软，需求回升仍显缓慢，销售增速平稳回落，市场价格持续下降，企业效益下滑，综合来看行业运行稳中偏弱。预计下半年经济仍将延续平稳运行基本态势，但由于经济调整、转型过程仍在继续，增速难见明显回升，仍将维持稳中偏弱基本格局。总体来看，生产资料市场规模继续小幅回落，需求回升仍待加强，供求矛盾依然突出。在目前这种形势下，市场复苏要立足于控制产能过快释放，保持供需基本均衡。

Biodegradable plastics or polymers are the ones which can be more than 90 percent broken down by microbes or the enzymes produced by them. It is important to distinguish between biobased and biodegradable plastics. Biobased plastics are those plastics which are manufactured from raw materials that are renewable. They may be but are not necessarily biodegradable. Additionally, the number of biobased plastics available in the market is more than the biodegradable plastics. There are different types of biodegradable plastics, such as polymers that are directly extracted from biomass and processed, polymers that are made from biobased precursors such as starch and PLA, and polymers made by bacteria, PHA, and PBS. Biodegradable plastics are different from conventional plastics and can be used for producing various products such as utensils, bags, furniture, carpets, films, bottles, cups, and packaging materials. Usage of biodegradable plastics helps reduce carbon emission, which is not possible with fossil fuel-based plastics.The Global Biodegradable Plastics market is expected to experience high growth during the period 2012-2016. One of the main reasons for the growth of the market is the increased awareness about the advantages of the biodegradable plastics over conventional plastics. The market is expected to grow at a CAGR of 19.60 percent over the forecast period.The Global Biodegradable Plastics market is driven by several factors. One of the major drivers in this market is the increasing demand for more eco-friendly packaging materials. The growth of the packaging industry is influenced by the need for non-toxic biodegradable plastics, which in turn has resulted in the increased demand for biodegradable plastics. Global rise in the prices of oil has also resulted in the shift toward use of biodegradable materials manufactured from renewable materials.
