Abstract Waste management systems are modelled to provide a public waste management service and need to be able to meet environmental sustainability requirements at a cost that is acceptable to system users/citizens. Overall environmental, economic, and/or socio-economic sustainability of waste management in previous publications is done through independent analyses and comparisons of obtained results or through multicriterial ranking of different alternatives where final results do not have a meaningful physical significance and cannot be interpreted independently. At the same time, those analysis either neglect time dependant changes by focusing on moment in time, or take into account changes in some timeframe changes but report only ranking focused single-score results, thus, results neglect time-dependent developments. All of these approaches are lacking some information needed for informed decision-making and/or are difficult to understand by wider groups of people. Thus, in this study, link between economic and environmental sustainability is analysed through newly defined single-score Economic Efficiency of Resource Recovery (EERR) index that shows the specific system cost for achieving identified resource recovery, while legislation based time dependent changes are taken into account through successive analyses for legislative most important years. This approach can be used for benchmarking the overall (environmental and economic) sustainability trends, while its graphical representation enables easier presentation of sustainability results and can be used for easier comparison of possible solutions and decision-making. The results show that the quality decision-making process needs to take into account the impact of expected changes on overall sustainability and evaluate how they will affect the actual perception of used technologies. In this context, it is shown that overall changes in sustainability, in comparison to the existing perception, can significantly change, depending on which technologies the system is based on.

Civil Participation

Civil participation is the main component of effective governance. The topicality of this paper lies in civil participation in decision-making defined by the principles of “new public governance” of the 21st century. This study aims to analyze the impact of civil participation in decision-making on waste management at the municipal level. In this work, the following aspects were considered: theoretical assumptions of civil participation; civil participation in the activities of institutions responsible for environmental protection; issues regarding the development of opportunities of citizens’ involvement in municipal waste management. The article is devoted to the theoretical assumptions about civil participation, theoretical model of analysis, and activity of institutions. To develop a theoretical model of analysis, a classification of civil participation was carried out. Among the methods used, one can mention the questionnaire. The analysis was focused on a legal basis for the activity of institutions; the actual activity of institutions and survey of representatives of the national environmental authorities in Lithuania. The results showed that currently there is no mechanism in Lithuania to ensure civil participation in municipal waste management. Civil participation is still formal and limited. Overall, citizens are informed about the decisions made, but they do not participate actively in decision-making. The analysis of civil participation capacity in waste management leads to the conclusion that Lithuania has no single mechanism to ensure civil participation in waste management. To enhance civil participation in decision-making on waste management, it is suggested to set up a council where the representatives of civil population are delegated.

The Impact

Educational institutions and, specifically, university campuses are large energy consumers and waste producers. The impact of university campuses on the local waste management increases with decreasing the size of the city/town where universities are located. Following the growing interest of the scientific community on the research for strategies to improve the environmental sustainability of educational institutions, this paper aims at proposing specific parameters to 1) measure the performance of university buildings in waste management, 2) detect anomalous situations that require improvements and 3) implement ameliorative actions. Specifically, parameters like the per-capita or surface-specific waste generation could help identifying the structures that may require primary interventions. With reference to the case of a medium-size university, the paper points out the advantages of the punctual tariff system for waste management adopted by the local utility company and critically analyses its weak points. Overall, this system offers great opportunities for improving waste management and for cost savings, but requires careful management policies by public institutions.

The Impact

This paper outlines a methodology for structuring a generic database of environmental impacts on the end-of-life phase of buildings, which can be used at the national level, in accordance with European standards. A number of different options are also considered for managing construction and demolition waste (CDW), as well as for promoting the circularity of materials in construction. The database structure has been developed for use by the main stakeholders who decide the disposal scenario for the main CDW flows, assess waste management plans, and identify the corresponding environmental aspects. The impact categories considered in this paper are global warming potential (GWP) and the abiotic depletion potential of fossil fuels (ADP (f.f.)). This lifecycle assessment (LCA) database further facilitates the identification of important information, such as possible treatments for CDW, or suppliers of recycled materials for use in new construction. Two demolition case studies were used to confirm the benefits of the proposed database. Two demolition scenarios are assessed—traditional and selective—in order to demonstrate the advantage of selective demolition in waste management. The results obtained from the environmental assessment of CDW flows demonstrate that the proposed database can be an important and useful tool for decision making about the end-of-life of construction materials, as it is designed to maximize their reuse and recycling. An innovative online platform can be created based on this database, contributing to the reduction of the environmental impacts associated with the end-of-life phase of buildings.

The Impact

Environmental inequality in animal husbandry is an important issue that matters in sustainable livestock production and environmental sustainability. In this context, the objective of this study is to measure and analyze the chemical oxygen demand (COD) discharge inequality from animal husbandry in the Liaoning province in China, as a case study in environmental inequality. Using the pollutant discharge coefficient method and environmental inequality indices, the study looks specifically at the impacts on unequal distribution and unequal economic efficiency in Liaoning in the period 2000 to 2016. The study explores the determinants of COD discharge inequality by constructing panel threshold regression models. The major findings are as follows. First, there is COD discharge inequality in distribution and in economic efficiency in Liaoning, and these were not reduced over time, despite a decline in the absolute quantity of COD discharge after 2013. Second, the impact of COD discharge inequality in economic efficiency lasted longer and was more serious across Liaoning compared with COD discharge inequality in distribution. Third, the quantitative upgrading of the agricultural industrial structure did not significantly reduce COD discharge inequality, and even led to a rise in inequality, especially in terms of economic efficiency. Ultimately, regional economic development turned out to be the key factor in inequality reduction. In addition, improvement in public fiscal support for science and technology also led to greater reduction in inequality.

The Impact

Although previous studies have explored the role of legal framework, industry norms, innovation, and the use of clean technologies to achieve sustainability, they have paid little attention to the role of employees in increasing a firm’s sustainability performance. This article develops a model based on social identity theory and proposes that employees whose organizational identification is rooted in the sustainability of the firm can influence the sustainability strategy of the firm through the participation process. Data were obtained from 421 employees of large fast-moving consumer goods manufacturers. The findings demonstrate that employee participation has a strong positive effect on all the components of sustainability (environmental and societal). Moreover, the findings show that the impact of employee participation on the components of sustainability is moderated by organizational identification in such a way that if employees have a strong sense of identification with their organization, their participation in decision making has a greater impact on the sustainability of their organization.

The purpose of the study was to develop a methodological toolkit for the substantiation of investment decisions on supporting regional environmental projects by state and private investors. The problem lies in the fact that traditional indicators of the efficiency of investment projects, such as net present value, budgetary efficiency, currently do not sufficiently meet the principles of sustainable economy, which underlie modern methodology for managerial decision making. The study of the opinions of investors shows their increasing willingness to take into account, when making investment decisions and decisions on financing projects, not only the economic efficiency, but also the impact of the results of companies’ activities on the environment and human health. At the same time, the question of how to take into account ESG factors (environment, social, governance) in the assessment of investment decisions remains controversial. The authors suggest a methodology that will contribute to the justification of management decisions regarding the support and stimulation of investment eco-projects. The method assumes a sequential passage of stages, at each stage the projects undergo an assessment procedure for compliance with the criteria that take into account the interests of various project stakeholders (government, investors, society) and the calculation of ratings: the rating of ESG factors and the rating of economic efficiency of eco-projects. The authors have also developed a matrix for managerial decision making to support an investment eco-project based on the analysis of the ratings obtained. The proposed conceptual approaches and models make it possible to clarify the methodological tools for effectiveness assessment of eco-projects, contribute to the improvement of the theory and practice of financial management, harmonization of ESG principles and investment management, adequate to the conditions of the concept of sustainable economic growth.

The problem of waste is very worrying because it has a direct impact on humans, especially the inclusion of plastic elements in the human body through fish and food exposed to microplastic. One way to overcome the problem of waste is to reduce waste from its source by sorting methods from the source and managed further through the process of recycling or upcycling into new products. Reducing waste from its source by sorting and then saving it in a Waste Bank is one promising breakthrough and can encourage people to actively participate in environmental management. The purpose of this study was to obtain a mapping model of the waste management service area in the city of Manado as needed. The research data was obtained through research on smash applications for waste banks supporting field research through observation and interviews. Data was analyzed by mapping the position of waste banks in the city of Manado. Furthermore, comparing the three garbage banks in Manado city to find a pattern of waste bank management with various indicators. The results of the study indicate that the current mapping of the position of waste banks in Manado consists of the center, the suburbs and outside the city. Furthermore, the results of the comparison of the three garbage banks conclude that the most effective waste bank is a waste bank in a residential area. An effective waste bank is one of the strategies for implementing 3R (Reuse, Reduce, Recycle) in waste management at its source at the community level. The implementation of the waste bank in principle is a social engineering to invite the public to sort out waste for environmental sustainability and public welfare.

Safe and clean environment is an essential requirement for maintaining life on earth and creating human friendly environment is one of the most important issues in the world today. The concern of this paper is to examine household preference and willingness to pay for waste management services. The population of the study is made up of the households in the Nsukka urban where simple random sampling techniques was employed to select 25 households from each of the six town in Nsukka urban, employing binary modelling using probit model to estimate the impact of both cultural and demographic factors and economic factors on household willingness to pay for waste management service. The result revealed that demographic factors such as age, household size and education have great influence on household willingness to demand for waste management in Nsukka urban area. Also, economic factors such, income level of the households, awareness of the household about the environment, impact of waste management service and cost of waste management service has positive significant impact on household willingness to pay for waste management services.
