Plastic recycling presents many challenges across the manufacturing workflow. One of the biggest challenges is controlling the uncertainty of feedstock quality. Variations in quality arise from mixtures of different polymer types in the recycling process. This is a step-by-step guide for the quality control of recycled plastics with the NETZSCH DSC 214 Polyma.
Ever since plastics have become a popular material, manufactures have produced a total of 8.3 billion tons of virgin plastic. The production and usage of plastic has been a resounding success. However, it is alarming what is happening to the plastic that has served its time. The challenges posed by mechanical recycling can be overcome with thermal analysis.
Sealing elements undergo continuous changes in operating and environmental conditions. They are subject to natural, thermo-oxidative or mechanical aging processes and must be replaced after a certain time.
Billions of pounds of carpets are generated annually worldwide. A large percentage of which ends up in landfills is problematic because nylon is non-biodegradable.
Limitations in landfill capacity and the environmental impact of disposing of carpet waste in this manner have made recovering nylon from carpet waste an increasingly important enterprise.
