“…Therefore, selecting temporal boundaries (Zucaro et al, 2015) is important. Even products and components of goods have a shelf life, in terms of durability, which should be considered from a supply chain perspective (Montorsi et al, 2018).…”

Life cycle assessment applied to waste management in Italy: A mini-review of characteristics and methodological perspectives for local assessment

Life cycle assessment (LCA) and related tools are commonly used to evaluate the potential environmental impacts of waste treatment scenarios. This manuscript presents a mini-review of studies published over the last 10 years in Italy and aims to investigate how life cycle thinking tools are applied to assess the environmental sustainability of local-level waste policies. Results reveal that different waste flows, technologies and policies have been investigated independently and in varying detail. Review suggests that boundary selection significantly affects LCA results; integration of different waste systems is therefore crucial to avoid spatial or temporal shifts of environmental impacts. Moreover, the description of methodological characteristics, limitations and transversal aspects of Italian waste management studies allows various stakeholders to assess the reliability of past and future research for waste policy planning and rebound effects prevention. This review also highlights the need to define minimum requirements of transparency and ease of reporting of the studies to private and public stakeholders. Finally, the paper investigates whether using both the organisational LCA and the life cycle sustainability approach for the overall waste management process may be useful to develop a standard method to address multi-functionalities and multiple sites.

“…The number of annual cycles was found to be a crucial parameter, with payback periods highly sensitive to electricity, gas and CO 2 prices, but approximately equal to 20 years. Waste heat recovery in water treatment and sewage sludge processing was also investigated in Refs [140][141][142]. Tańczuk et al [140] analyzed the recovery of process waste heat from a digested sewage sludge medium-temperature belt dryer.…”

“…The air-air waste heat recovery exchanger was optimized, based on annual simulation of operating conditions and maximization of the net present value. Montorsi presented an economic assessment of a waste to energy system in an urban sewage treatment plant [141]. The integrated anaerobic digestion and gasification system converted residues from the plant to bio-fuels for use in a CHP unit.…”

The environmental impact of the energy sector and the security and economics of energy supply and utilization have been raising increasing concerns, stimulating the search for innovative solutions for a sustainable use of resources. This article provides an overview of published research in this area, with a focus on papers contributed in special issues of leading journals dedicated to the series of Conferences on Sustainable Development of Energy, Water and Environment Systems (SDEWES), including the articles in the current special issue. Based on this review, research trends are identified and achievements supporting the energy transition are highlighted. The studies that focused on regional or urban energy planning have aimed at (a) increasing penetration of renewable energy sources, (b) optimizing the mix of centralized and distributed technologies (c) introducing additional flexibility in the power sector and d) identifying solutions for sustainable heating. Conversely, researches focused on individual plants or users have targeted the development of technologies for efficient energy use in industry and buildings, with emphasis on multigeneration and waste heat utilisation. The analysis highlights that future scenarios based on sustainable energy systems are viable, although their implementation will require further efforts by researchers and investors and active involvement of consumers.

“…Thus, the scientific community and the Institutions are challenged in developing green energy systems capable to replace the fossil fuels. Numerous technologies for producing bioenergy heat and power already exist, such as solid wood heating installations for buildings and biogas digesters for power generation as well as large-scale biomass gasification plants are also employed for heat and power generation [2,3,4,5]. Within this context, plastics has attracted considerable interest since its production has reached about the 311 million tonnes in 2014 [6] determining a continuous growing in waste accumulation every year.…”

Development of an experimental test rig for the pyrolysis of plastic residues and waste tires

The paper presents the design of the experimental apparatus developed in order to analyse the performance of a prototype of a pyrolysis system for the exploitation of the plastic residues of industrial processes and the end of life tires. The small scale pilot prototype is specifically designed for carrying out an experimental campaign aimed at determining the influence of different plastic types on the yield and on the quality of the liquid oil, gas and char obtained in the pyrolysis process. The study investigates the effect of different mixture of various plastic products mainly made of polyethylene, styrene butadiene rubber, nylon and natural rubber. The prototype is equipped with a control system able to monitor the main operating parameters of the process, such as the pyrogas pressure and temperature as well as the temperature inside the reactor where the pyrolysis takes place. The monitored variables are employed for deriving correlations among the operating conditions and the yield of the pyrolysis process. Therefore, further analysis concerns experimental measurements in order to estimate the main compounds that are contained in the syngas in comparison to the different plastic wastes analysed. Finally, the emissions of the small-scale prototype are evaluated.
