A large number of components in automobiles are made from plastics. They have to meet high safety, heat resistance, and quality requirements.
这就是为什么到目前为止，只有石油基材料适用于在经受极高磨损的汽车中制造塑料组件的亚博网站下载原因。在大多数情况下，不能回收此类材料。亚博网站下载
而相同类型的塑料通常可以机械回收，而混合塑料废物的回收却是一个重大挑战。
因此，Karlsruhe技术研究所（KIT）和奥迪的智囊工业资源策略正在启动一个化学回收的试点项目，以便将这种混合的塑料分数喂入一个持有资源的圆形系统中。
“许多组件尚未有可能回收汽车塑料。这就是为什么我们与奥迪一起在这里进行开创性的工作，”says Professor Dieter Stapf, Head of KIT's Institute for Technical Chemistry, who also is involved in the THINK TANK.
"If we want to close these loops, we need to develop suitable methods."到目前为止，化学回收一直是唯一可用于将这种混合塑料废物转化为产品的方法，该产品的质量与新产品相匹配。
As a result, a wider range of plastics can be recovered, Stapf says."Such closed material loops save valuable resources, because less primary material is required. This, in turn, saves energy and costs - and is beneficial to the environment,"Kit工业生产研究所的Rebekka Volk博士说。
The pilot project"Chemical Recycling of Plastics in Automotive Engineering"is conducted by the THINK TANK Industrial Resource Strategies that has been established at KT by the Baden-Württemberg State Government together with industry and the support of academia.
“负责使用资源是工业，科学和政治的共同义务。智囊团汇集了所有能力来掌握这一重大挑战并为社会和环境服务的能力，”亚博老虎机网登录KIT副总裁托马斯·希特（Thomas Hirth）说，创新和国际事务副总裁，智囊团发言人。
“化学回收可能是综合塑料回收的主要组成部分。这使其成为汽车行业的一个有趣主张。智囊团和奥迪正在共同解决一个核心问题，即使汽车在将来使汽车更具可持续性和环境友好，无论其不管他们的类型如何动力总成。智囊团专注于原材料循环的整体视图，”智囊团董事总经理克里斯蒂安·库恩（ChristianKühne）博士说。
Audi is among the first automotive manufacturers testing this recycling method in a pilot project with plastics from automotive engineering.
"We want to establish smart circular systems in our supply chains and make efficient use of resources,"says Marco Philippi, Senior Director Procurement Strategy of Audi.“化学回收具有很大的潜力：如果可以通过热解油而不是石油生产塑料成分，则可以显着增加汽车可持续制造的组件的比例。从长远来看，这种方法也可以播放一种方法在寿命终止的车辆回收中的作用。”
The "汽车工程中塑料的化学回收”试点项目的目标是创建用于塑料的智能圆形系统，并建立此方法，以补充机械回收和替代能量恢复。
Partnering with KIT's THINK TANK, Audi intends to initially test the technical feasibility of chemical recycling and to evaluate the method in terms of its economic efficiency and environmental impacts.
For this purpose, the company provides plastic components that are no longer needed, such as fuel tanks, wheel trim parts, and radiator grills, from Audi models returning from the German dealership network, for example.
The plastic components are processed to pyrolysis oil by chemical recycling. In the medium run, components based on pyrolysis oil can be used in automobiles again. If technical feasibility will be demonstrated, Audi will industrialize the technology and progressively apply it to more and more components.
更可持续产品的热解方法
可持续循环经济的研究和技术开发是套件的主要主题。"We are systematically studying the potentials of pyrolysis and how pyrolysis processes have to be designed on a large scale for maximum recycling of resources,"Stapf说。
Chemical recycling of plastic wastes can help make modern products more sustainable and prevent greenhouse gas emissions.
