“…Local effects of waste policies should be outlined as well. For example, LCA results might be more closely linked soil management and erosion (Bosco et al, 2013; Lazzerini et al, 2016), models of air emissions dispersion, exposure and toxicity (Renzulli et al, 2016; Schiavon et al, 2014), or odours and noise.…”

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

et al. 2021

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.

“…However, the research carried out by [7] indicates that the GHG emissions from hand-drier manufacturing are about only 11% the emissions from hand-drier operation by one order of magnitude. Thus, as emerged in a previous paper [18], LCA results cannot be generalised and require a precise definition of the context and the used data.…”

Different hand-drying methods entail different costs and impacts on humans and the environment. This paper presents a methodology to facilitate the decision on the convenience of installing electrical hand driers in place of the conventional toilet paper towels in the restrooms of public places. Specifically, a procedure including both economic and environmental aspects is proposed and the Monte Carlo method is employed to account for the several uncertainties of all the variables involved. From the economic point of view, the number of daily usages of restrooms results as the key variable determining if one option is preferable to the other. From the environmental point of view, the carbon footprint was calculated for four scenarios considering two options for the electric energy grid mix and two options for waste treatment. The comparison between the four scenarios revealed that hand driers may be preferable to paper towels when the waste treatment alternative is landfilling. The results are more uncertain when the waste treatment option is incineration. The integration of economic and environmental aspects reveals as a useful strategy to fully assess the convenience of choosing one option rather than another, without limiting the decision to only one aspect. Additional information on processes and logistics are anyway necessary to reduce the uncertainties of the results.

“…This is mainly because of unsatisfactory levels of MHSW separate collection, which causes poor effectiveness of the subsequent processing. MHSW separate collection is the prerequisite for the MHSW reduction [6] and causes fewer environmental problems than other solutions [7]. Hence it is of high importance in effectively mitigating the environmental problems caused by MHSW [8,9].…”

Abstract:Municipal household solid waste (MHSW) has become a serious problem in China over the course of the last two decades, resulting in significant side effects to the environment. Therefore, effective management of MHSW has attracted wide attention from both researchers and practitioners. Separate collection, the first and crucial step to solve the MHSW problem, however, has not been thoroughly studied to date. An empirical survey has been conducted among 387 households in Harbin, China in this study. We use Bayesian Belief Networks model to determine the influencing factors on separate collection. Four types of factors are identified, including political, economic, social cultural and technological based on the PEST (political, economic, social and technological) analytical method. In addition, we further analyze the influential power of different factors, based on the network structure and probability changes obtained by Netica software. Results indicate that technological dimension has the greatest impact on MHSW separate collection, followed by the political dimension and economic dimension; social cultural dimension impacts MHSW the least.
