Material Recycling of Polyolefin-Rich Plastic Fractions

In terms of an improved resource efficiency,and consistent with the actual European legislation, the material recycling of plastic has to be enhanced. The material recycling often fails because the plastic waste consists neither of monomaterial, nor is it clean enough. The development and the industrial implementation of material recycling processes gets continuously more attractive, particularly due to the increasing raw material prices of primary resources. In terms of plastic waste, thermal or thermochemical conversion process can be taken into account for material recycling, like for example pyrolysis, thermal or catalytic cracking. Ahomogeneous, and impurity-lean feedstock is the precondition for a stable operation of those conversion processes, and the production of usable products (petrochemical intermediates). Incontrast to mechanical recycling processes, thermochemical conversions need neither pure Feeds nor mono-materials.
