Efficient collection systems and information about the characteristics and quality of collected secondary plastic waste flows are of fundamental importance for the development of circular economies. In order to assess the effectiveness of the implementation of separate collection systems for plastic packaging, especially polyethylene terephthalate (PET) bottles, characteristic of the collected PET bottles in street mesh containers were studied in the city of Perm, Russia. The share of extraneous fractions was assessed and differentiation was carried out by volume, type of product, label presence, shape, content of solid and liquid impurities and colour. These results indicate that PET composition in different seasons is very similar, despite the assumption that the consumption of PET bottles in the spring and autumn seasons varies. In the mesh containers, up to 34% of the items were foreign objects, considering that only PET bottles should be collected. In each dimensional flow of PET bottles, the proportion of transparent bottles prevailed; it ranged from 31% to 70%. Based on the results of the experiment, almost all PET bottle categories had a standard shape, except packaging for food products and household chemicals, in which 26–27% of PET bottles had a non-standard shape. The results about charactersitic of source-separated PET bottles are fundamental for goal-oriented design and implementation of collection, recycling technologies, secondary separation facilities, the economics of recycling intitatives and reverse vending machines for collecting materials.

高效的收集系统以及有关收集的二次塑料废物流的特征和质量的信息对于发展循环经济至关重要。为了评估实施单独的塑料包装收集系统（尤其是聚对苯二甲酸乙二醇酯（PET）瓶）的有效性，在俄罗斯彼尔姆市研究了街头网状容器中收集的PET瓶的特性。评估外来部分的份额，并通过体积，产品类型，标签存在，形状，固体和液体杂质含量以及颜色进行区分。这些结果表明，尽管假设春季和秋季季节PET瓶的消费量有所不同，但不同季节的PET组成非常相似。考虑到仅应收集PET瓶，在网状容器中，多达34％的物品为异物。在PET瓶的每个尺寸流中，透明瓶的比例占优势。范围从31％到70％。根据实验结果，除食品和日用化学品的包装外，几乎所有PET瓶类别均具有标准形状，其中26-27％的PET瓶具有非标准形状。有关按源分离的PET瓶特性的结果对于目标导向的设计和实施，回收技术，二次分离设施，回收方法的经济性以及用于收集材料的反向自动售货机是至关重要的。在PET瓶的每个尺寸流中，透明瓶的比例占优势。范围从31％到70％。根据实验结果，除食品和日用化学品的包装外，几乎所有PET瓶类别均具有标准形状，其中26-27％的PET瓶具有非标准形状。有关按源分离的PET瓶特性的结果对于目标导向的设计和实施，回收技术，二次分离设施，回收方法的经济性以及用于收集材料的反向自动售货机是至关重要的。在PET瓶的每个尺寸流中，透明瓶的比例占优势。范围从31％到70％。根据实验结果，除食品和日用化学品的包装外，几乎所有PET瓶类别均具有标准形状，其中26-27％的PET瓶具有非标准形状。有关按源分离的PET瓶特性的结果对于目标导向的设计和实施，回收技术，二次分离设施，回收方法的经济性以及用于收集材料的反向自动售货机是至关重要的。除了食品和日用化学品的包装外，其中26％至27％的PET瓶具有非标准形状。有关按源分离的PET瓶特性的结果对于目标导向的设计和实施，回收技术，二次分离设施，回收方法的经济性以及用于收集材料的反向自动售货机是至关重要的。除了食品和日用化学品的包装外，其中26％至27％的PET瓶具有非标准形状。有关按源分离的PET瓶特性的结果对于目标导向的设计和实施，回收技术，二次分离设施，回收方法的经济性以及用于收集材料的反向自动售货机是至关重要的。
