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.

刚性聚烯烃和聚苯乙烯包装废弃物在单独废物收集中的组成:奥地利2021年至2024年的案例研究
塑料包装垃圾目前正在稳步增加,其循环处理是重要的。本研究考察了奥地利单独废物收集系统中刚性PO和PS包装废物(PW)的组成,特别关注废物组成,包装特征,包括包装格式,着色,食品/非食品,标签和封闭类型,以及设计回收潜力。研究结果表明,13m -%的分类垃圾收集是由刚性PO和PS PW组成的。高密度聚乙烯PW主要由非食物中空体组成,而PS由食物杯组成。聚丙烯PW由食品托盘,杯子和非食品空心体组成。目标PW主要是白色(40 m-%)和自然(35 m-%)。食物杯主要是直接印刷的。标签的可回收设计评估确定54 m-%为“良好”,24 m-%为“有限”,22 m-%为“差”。这项研究提供了新的见解关于PW组成,以争取增加循环度。

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.
