The usage of plastics in automobiles has continued to grow over the past 20 years. The principal reason for this is which they help to reduce vehicle mass. A lighter car consumes less fuel, which results in less exhaust emissions also. In addition, plastic parts are not susceptible to corrosion, give flexibility and resilience for added safety, have very good thermal insulation, decrease noise and enable optimum space usage. Today, the average vehicle includes 12-15% plastic parts. Let's assume that the average car weighs 1300 kg, this quantities to 150-200 kg of plastic per vehicle.
The figures above clearly show the huge potential for plastics recovery that is based on the automotive sector. The European countries Union's End-of-Life Vehicle Directive 2000/53/EC serves as a significant drivers for recycling within the automotive industry, establishing sufficient systems for the collection of ELVs and tightened environmental treatment criteria. It units goals for the recovery of vehicle parts and recycling, and promotes manufacturers to create their vehicles with the reuse and recycling of parts in mind. According to the directive, currently at the least 85% by an average weight of the end-of-life vehicle should be reused or retrieved, including 5% energy recovery. January 2015 as of, the speed of reuse and recovery should achieve at the least 95% with a minimum of 85 % recycling by the average fat per vehicle per year.
The plastic parts found in the automotive industry are mainly injection molded, such as for example dashboards, bumpers, fluid tanks, handles, buttons, casings, containers, clamps, and sockets. The recycling task here's that very strengthened plastics frequently, as well as two- or multi-component injection shaped parts are used.
Plastic parts from the motor vehicle industry have special requirements for recycling that require to be looked at in order to get yourself a product that is fit for even more usage. The removal of contaminants and odor by high-vacuum extraction and melt filtration, as well as introduction of additives for up-cycling will be the main issues to be taken into account. Procedure versatility for quick and efficient materials changeover and a wear-resistant machine style - for recycling reinforced plastic parts which contain glass fiber, for example - enable recyclers to procedure diverse input materials.
Volatile and solid impurities have to be extracted to be able to produce high-quality regranulate ideal for reuse thoroughly. Particular vacuum degassing extruder modules enable reprocessing of shaded and contaminated parts. According to the type of contamination, different filter systems and sizes are used extrusion equipment manufacturers
which also help to decrease melt reduction.
