Carbon savings from chemical recycling

For the ecological categorization of granules from chemical recycling, the extractive industry has provided in-depth life cycle assessments, which extensively examine the assessment of the ecological footprint of these materials and look at their impact above all from a holistic perspective. Life cycle assessments show that chemical recycling of plastic waste can achieve significant carbon savings compared to thermal utilization. Our model calculation reveals 1.8 tCO2 per ton of plastic waste from incineration, incl. energy credit, compared to only 0.7 tCO2 from chemical recycling. This is relevant above all for plastic packagings which are not capable of mechanical recycling and currently overwhelmingly go into thermal utilization.

A comparison of the carbon footprint of chemically recycled plastics with that of plastics consigned to thermal utilization shows that the carbon footprint of granules from chemical recycling is smaller by 58%.[1]
