30 recovery –The end is just the beginning Sixty percent of all materials made from plastics have a life of over eight years. one-quarter have already reached the end of their lifetime after one year. But used plastics are also a valuable source of raw materials. recovery of waste plastics must There are four approaches to the recovery of plastics: thermal recovery, mechanical recycling, organic recycling and feedstock recycling. Which of these approaches is used depends on the type of plastics and the composition of the waste streams containing the plastic. Eco-efficiency studies can help decide which method is most appropriate. Energy recovery ( incineration with recovery of energy) Almost all post-consumer plastics – whether separated according to polymer type or mixed, clean or with impurities – can be used to re - cover energy because all plastics have a high calorific value. Most plastics contain about as much energy as crude oil. Clean incineration with energy recovery in suitable efficient plants reduces the burden on the environment and conserves fossil fuels. take equal account of environmental, economic and technical aspects. in germany, nearly 80 percent of all waste plastics are now recovered. in Europe as a whole, the rate is almost 50 percent. • Telephone housings and granules recovered from them for the production of plastics containing recycled material • Engine cover made from mechanically recycled polyamide Mechanical recycling If large amounts of homogeneous, uncontaminated scrap waste is available, for example in production and processing plants or from industrial packaging, the plastic can be remelted to produce new molded components. With more complex products, the effort required for dismantling, sorting, cleaning and processing limits the benefits of mechanical recovery. Organic recycling Organic recycling is also an option for biodegradable plastics. The BASF products Ecoflex ® and Ecovio ® have been developed primarily for applications such as shopping bags and bags for organic waste, which – together with biowaste – can be transformed into valuable compost in an industrial composting facility.
Degradation of Ecoflex ® in the first week … … in the second week … … and in the fourth week Feedstock recycling Mixed plastic wastes can also be reduced by chemical means to their original components which can then be re-used as raw materials. Thus, mixtures of different and even contaminated plastics can also be processed. The resulting raw materials can then be used to manufacture new material to the same standard as if it were made from crude oil, while conserving fossil fuel. As a major plastics manufacturer, BASF has done pioneering work in designing recovery options for wastes containing plastics by developing groundbreaking recovery methods. Together with companies in the plastic manufacturing industry and their customers, BASF continues to participate in various activities to open up new options for recovering waste containing plastics that are viable in both environmental and economic terms.
