Special Issue Information

Dear Colleagues,

Municipal solid waste (MSW) management faces interesting challenges related to climate change, circular economy, and dematerialization. Nowadays, MSW management seeks to focus on GHG reduction along with collection, treatment, and the final disposal chain. Furthermore, new paths related to smart cities, climate change, and the circular economy are becoming challenging issues. Additionally, food-waste prevention and reducing environmental impacts through multicriteria decision analysis (MCDA) and life cycle assessment (LCA) are emerging themes.

Collection strategies in low-density territories are also of high interest, since matter balances sustainability with universality. Another important subject is the rapid increase of artificial intelligence (AI), which is still sporadic with regard to household prevention and MSW collection.

The purpose of this Special Issue is to gather research articles focused on relevant trends, solutions, and sustainability improvements in MSW management.

A special (but not exclusive) emphasis is on the innovative solutions to improve the following:

  • Innovative attitudes on MSW and food-waste prevention;
  • Applications of artificial intelligence and smart-cities outlooks;
  • LCA and multicriteria decision analysis;
  • Original approaches for technoeconomic evaluation of curbside collection;
  • New paths on circular economy and recycling;
  • Accessibility, efficiency, and affordability in low-density territories;

Selected reviews, original case studies, and research articles are subject to trustworthy peer-review procedures seeking to achieve advances in MSW sustainability.

Incentive Mechanism for Municipal Solid Waste Disposal PPP Projects in China

In municipal solid waste disposal public–private-partnership (PPP) projects, economic benefits, as well as social and ecological benefits, are critical in sustaining sustainability development. However, private investors may make more efforts for economic benefits than for social and ecological benefits out of self-interest. Because the government does not have the same information that the investors have, information asymmetry leads to opportunistic behavior. To solve these problems, principal–agent models were established to analyze the incentive mechanism for encouraging investors to adopt a positive attitude toward both economic benefits and social and ecological benefits, inhibiting investors’ opportunistic behavior. In particular, numerical simulation was carried out to analyze the relationships between related parameters (c1,c2,ct,a,β,k,λ,p). The results show that the investors with higher comprehensive abilities are more willing to make efforts for social and ecological benefits. An increase in incentive and governance intensity would help to encourage investors to make more efforts for project benefits and to lower the level of opportunistic behavior adopted by investors. The complexity of the task and the fuzziness of the perception of effort input results aggravate the uncertainty and risk of the projects due to information asymmetry. Therefore, real-time and positive incentives are important. In order to ensure the social and ecological benefits of a project, performance standards should be set according to the actual situation; investors prefer fixed compensation with lower risk, but fixed compensation does not have incentive effect, and the proportion should not be too high.

Energy recovery from municipal solid waste is one of the means to attain sustainable development. Multiple factors involving several location specific situations, both measurable and intangible, makes decision making for technology selection very difficult. In this paper, a multi criterion evaluation system for municipal solid waste treatment strategies is established on the basis of specific, measurable, attainable, relevant and trackable situations, to prove the effectiveness of this method. From among various alternatives, three prominent strategies, namely, incineration, anaerobic digestion and composting are considered for the evaluation. Exhaustive data collection is done from conducting field studies, as well as from published data. Three types of communities are evaluated by this technique, namely, typical cities in developed countries, ‘A’ grade cities in India and ‘B’ grade cities in India. The purpose of the study is to evaluate the effect of community specific situations on the right choice of waste disposal method using a technique for order of preference by similarity to ideal solution (TOPSIS) approach, where weights of criteria are determined by means of entropy weight method. The case study shows that the proposed evaluation results are reliable, which are more coincident with the reality, since the most relevant factors for selection have been used backed by exhaustive field data collection. Policy makers gain from the outcome of this study by guiding them through technology selection. So, the adopted approach should be promoted widely in the evaluation of waste treatment strategies, to realize sustainable development. Full article

In the European Union, basic strategy results from the need to provide intelligent, sustainable, and inclusive growth, along with respect to social and economic impacts of waste treatment. The paper focuses on municipal waste and its separation. Generally, within global waste management initiatives, the main goal is to minimize the negative effects of waste on the environment, as well as to increase and optimize the sources’ efficiency in the waste economy. Research on municipal waste development and its separation was done in individual regions of Slovakia to find if socially weaker regions have worse waste treatment. The results were compared according to the waste development per inhabitant and per household, as well as through rate indexes, which are connected to relationships between waste, social, and economic indexes. The results confirmed research results from other countries that show that the volume of municipal waste is increasing due to increased living standards of inhabitants. However, on the other hand, waste separation rates also increased—mainly based on the legislative support. Full article
