Mechanical or chemical recycling? That is the wrong question
![]()
Asking "mechanical or chemical recycling?" puts the debate on the wrong level. No single technology is suitable for every polymer and every waste stream. Mechanical recycling generally preserves the greatest value in clean, homogeneous materials. Dissolution, depolymerisation, pyrolysis and gasification have different mechanisms, input requirements and real material yields. What matters is not the declared yield of oil or pellets, but how much waste actually returns to new polymer production, with what energy demand and product quality. These technologies should complement one another, not compete for the same feedstock.

Defects in Plastics Processing – I Am Looking for Real Cases from Production
![]()
Real production defects in plastics processing can tell us far more than appearance alone. I am looking for photos of defects in pipes, profiles, sheets, films and other extruded plastic products. In return, I will provide a short technical comment: possible causes, areas to check first and directions for further analysis. The most interesting cases may inspire neutral examples in my upcoming book “Plastic Extrusion. Pipes • Profiles • Sheets • Films”. Submitted photos will not be published, and no company names, production sites, customers or production data will be disclosed.
