Product Service Systems

Business models like product-service systems (PSSs) often recognise different sustainability goals and are seen as solutions for the impacts of consumption and fast fashion, but there is a lack of evidence supporting the environmental claims of such business models for clothing. The research aimed to understand if rental clothing business models such as PSSs have the environmental benefits often purported by quantifying the environmental impacts of rental formal dresses in a life-cycle assessment (LCA) in a case study in Stockholm, Sweden. The effects of varying consumer behaviour on the potential impact of a PSS vs. linear business model are explored through three functional units and 14 consumption scenarios. How users decide to engage with clothing PSSs dictates the environmental savings potential that a PSS can have, as shown in how many times consumers wear garments, how they use rental to substitute their purchasing or use needs, as well as how consumers travel to rental store locations.

The paper describes an installation for the degradative depolymerization of polyolefin materials obtained from wastes, hereinafter also referred to as depolymerization for simplicity. The plant, on an industrial scale, is one of the few operating in Poland. However, it is one of the most modern plants in this industry. Design solutions, construction of particular technological lines, compliance with national and EU regulations and the high level of process safety were described in this paper as well as compared to other plants of this type in Poland. Different solutions were presented in drawings and photos of the plant and in fragmentary technological diagrams. The types of waste and the methods of their processing by the plant were also characterized in accordance with the applicable regulations. The waste throughput is from 2000 to 4000 kg/h, while the efficiency of the depolymerization installation itself is 1500 kg/h. The industrial-scale depolymerization process is carried out in one or two stages: by homogenization (extraction) at a temperature up to 200 °C and depolymerization at temperatures up to 400 °C. The obtained products (energy goods) are sold for further processing. The processes, devices and methods are characterized by novel, innovative solutions, covered by a number of patents, which are also described below. The advantage of the presented technology is the substantial simplification of the process and thereby a considerable reduction in investment costs. Among others, the processes of distillation and rectification (low- and negative-pressure) were abandoned.

This research is motivated by the success of the community in the KB village in making recycled waste handicrafts into souvenirs so that these handicrafts can support the family economy and improve the community's economy. The success of this activity is the ability of the instructor and manager of PKBM Farilla Ilmi in empowering the community. In this activity, the residents of KB village can to get the proceeds from the sale of waste recycling crafts of approximately Rp. 500,000 a month. This study aims to describe community empowerment through PKW crafts to recycle waste into souvenirs seen from the aspects of knowledge, aspects of skills, and aspects of mental attitudes. The research approach is qualitative, with the type of research is a case study. Sources of data in this study consisted of mothers from the KB Bangau Putih village as research subjects and instructors and managers as research informants. The data collection techniques used were interviews, observation, and documentation. The data analysis technique used was data reduction, data presentation, and concluding. The data validity technique used source triangulation. The results of this study indicate that community empowerment through PKW crafts for recycling waste into souvenirs is very good, this can be seen from: (1) Aspects of knowledge obtained from the results that community empowerment through PKW recycled crafts into souvenirs can be seen increasing public knowledge about processing waste into useful items. (2) In the aspect of skills, the results show that community empowerment through PKW crafts to recycle waste into souvenirs shows that people's skills in processing waste have increased. (3) the mental attitude aspect obtained from community empowerment through PKW handicraft recycling of waste into souvenirs can be seen from forming a mental attitude of people who care and are confident about what they do.Keywords: Empowerment, Waste Recycling Crafts, Kampung KB Bangau Putih
