Abstract
Plastic packaging waste is currently steadily increasing and its circular treatment is of importance. This study examines the composition of rigid PO and PS packaging waste (PW) in the Austrian separate waste collection system, particularly focusing on waste composition, packaging characteristics, including packaging format, colouration, food/non-food, type of labelling and closures, and the design-for-recycling potential. The findings indicate that 13 m-% of separate waste collection is comprised of rigid PO and PS PW. High-density polyethylene PW comprises primarily non-food hollow bodies, whereas PS is comprised of food cups. Polypropylene PW is composed of food trays, cups and non-food hollow bodies. The targeted PW is predominantly white (40 m-%) and natural (35 m-%). Food cups are primarily directly printed. The design-for-recycling evaluation of labelling identified 54 m-% as “good”, 24 m-% as “limited”, and 22 m-% as “poor”. This study provides new insights concerning PW composition to strive for increased circularity.
期刊介绍:
The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns.
Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
