Multilevel statistical entropy analysis (SEA) is a method that has been recently proposed to evaluate circular economy strategies on the material, component and product levels to identify critical stages of resource and functionality losses. However, the comparison of technological alternatives may be difficult, and equal entropies do not necessarily correspond with equal recyclability. A coupling with energy consumption aspects is strongly recommended but largely lacking. The aim of this paper is to improve the multilevel SEA method to reliably assess the recyclability of plastics. Therefore, the multilevel SEA method is first applied to a conceptual case study of a fictitious bag filled with plastics, and the possibilities and limitations of the method are highlighted. Subsequently, it is proposed to extend the method with the computation of the relative decomposition energies of components and products. Finally, two recyclability metrics are proposed. A plastic waste collection bag filled with plastic bottles is used as a case study to illustrate the potential of the developed extended multilevel SEA method. The proposed extension allows us to estimate the recyclability of plastics. In future work, this method will be refined and other potential extensions will be studied together with applications to real-life plastic products and plastic waste streams.

Plastic Waste Recycling

The research aims to increase people's creativity in managing plastic waste into goods that have economic value. This research raises the issue of tackling plastic waste in Lumajang Regency. The object of this research was conducted in Pasrujambe District, Lumajang Regency. This research uses a qualitative approach with a case study model. Data collection in this study used two ways, namely interviews and observations. Furthermore, after the data was collected from the informants, analysis was carried out. The results of this study indicate that the Pasrujambe community consisting of PKK, Gerbangmas and PKK Friends enthusiastically participated in the training stages. Starting from plastic waste creation training, marketing training through social media to simple accounting training. The results of this training the community can make, among others, bags, plastic drinking containers, flowers, pencil cases, vases and so on. In addition, the community has also been able to market these products through FB, WA and Instagram and the community has also benefited from the plastic waste creation products they make.

Plastic or polythene bags, these non-biodegradable toxic items have been playing a major role in degrading our environment, especially our oceans. But now there might be a solution to tackle this mounting problem, using plastics to build roads. The idea is to create roads that are durable and also to get rid of potholes. Given the current plastic crisis, the aim of this case study is to make sure that plastic waste does not reach the landfills or water bodies and to ensure that the 3 R’s –Reduce, Reuse and Recycle are implanted effectively.
