“…Concerning the waste management through AD, Lamnatou et al [ 10 ] showed that the transportation of organic waste impacts from 44% to over 70% of the whole environment. Hence, the introduction of a transfer station or small waste treatment plant with a view to a decentralized system, instead of a bigger one, could decrease environmental impacts, such as energy demand and emissions, especially in medium and large cities [ 11 ]. Despite the economic cost required by new infrastructures, the introduction of an AD plant at a local site could reduce the cost of waste transportation and generate energy from biogas combustion.…”

Anaerobic digestion (AD) of organic fraction of municipal solid waste (OFMSW) is considered an excellent solution for both waste management and energy generation, although the impacts of waste collection and transportation on the whole management system are not negligible. AD is often regarded as a centralized solution for an entire community, although recently, there has been some debate on the adoption of decentralized, smaller facilities. This study aims to evaluate the techno-economic feasibility of an AD plant at the local scale for the treatment of organic waste generated from urban districts. Depending on the type of feedstock, two scenarios were evaluated and compared with the reference scenario, based on composting treatment: (1) mono-AD of OFMSW and (2) co-AD of OFMSW and sewage sludge (SS). Furthermore, different district extensions of the metropolitan area were considered with the goal of determining the optimal size. Results showed the advantage of the two scenarios over the reference one. Scenario 1 proved to be the most suitable solution, because the introduction of SS in Scenario 2 increased costs and payback time, rather than generating a higher waste amount and lower biogas yield. The preferred district extension was the medium-sized one. Capital cost strongly affected the economic analysis, but revenue from the city for the management operation of the organic waste could significantly decrease costs. Further studies about the differences in the type of feedstock or the introduction of other criteria of analysis (such as environmental) are considered necessary.

“…Waste-to-energy (WTE) incineration plants are inextricably linked to the circular economy system, social harmony, environmental outcomes, risk assessment, and energy transformation [ 49 ]. Taşkin et al [ 50 ] evaluated three different municipal solid waste (MSW) management strategies with LCA method in terms of environment and energy. Dastjerdi et al [ 51 ] adopted the LCA method to study the potential of WTE technologies in the areas of energy recovery and greenhouse gas emissions.…”

This paper assesses the environmental loads of polypropylene and PP-PE-PET mixed-plastic products throughout the products’ life cycle in the production stage, with particular focus on the looping method. A life cycle model of homogeneous and mixed-plastic products has been developed from the raw material extraction and production phase through its transport with the help of the life cycle assessment method. To find the answers to the questions posed, different impacts were analyzed by the GaBi 9.5 software. The analysis lasted from the beginning of the production process to the end. The aim of this research was to determine the energy and material resources used, the emissions produced, and the environmental impact indicators involved. This article examines three scenarios in the production stage, based on the usage of plastic scrap and process water: (1) plastic scrap and wastewater are recirculated with looping method; (2) plastic scrap goes through an incineration process and wastewater is treated in a municipal wastewater treatment plant; (3) plastic scrap is sent to a municipal landfill and wastewater is treated. This article tries to answer three questions: (1) how can we optimize the production stage? (2) Which materials and streams are recyclable in the design of the life cycle assessment? (3) What is the relationship between the environmental impacts of homogeneous and mixed-plastic products? The results of this research can be used to develop injection-molding processes with lower environmental impacts and lower releases of emissions.

“…Aspects related to demography regarding the generation of SUW may be associated with human activity and the economic status present in said community. A current model of organic matter will provide several guidelines to have a general vision of the waste generated by them, considering the inputs that it covers, the production, and the outputs that are being the SUW [5]- [7] III. RESULTS AND DISCUSSION It began by quantifying the different types of inputs to finally obtain a value determined by the kilograms that enter during a year, as seen in Fig.…”

The high growth of Urban Solid Waste forces to seek measures to handle this waste. Applying advanced Thermochemical technology will take advantage of this waste in order to obtain Sustainable Energy. The objective of this study is to analyze the input, production and output behavior of this type of waste so that it can be transformed and used for energy purposes, based on the needs of the community. It is a quantitative, experimental study; after understanding the residual behavior of the community and applying the appropriate technology, it was obtained the quantified amount of energy (975'000 kWh) required for the different proposed scenarios. These scenarios are the use for public lighting, sale and domestic. The thermochemical method applied is not only efficient to extract energy from these wastes but also provides a compatible and environmentally friendly energy source. This energy source was used to supply a local school and 948 homes. The ideas es to achieve a paradigm shift, to avoid thinking that Urban Solid Waste that is generated from day to day is something useless; on the contrary, it is a vital source to provide a basic service for human beings. From a financial point a view, it is estimated that the initial investment will be recovered in the next 10 years, which, seen in the long term, is the useful life of the Pyrolysis plant due to working with the minimum raw material input standards.
