Special Issue Information

Dear Colleagues,

Sustainable solid waste management (SSWM) is an emerging problem in an increasing number of countries due to the misconnection among management networks. SSWM requires the incorporation of economic benefits, environmental impacts, and social assessment perspectives as it often encounters difficulties since authorities cannot confront the multiperspectives (Bui et al., 2020). Authorities are necessary for all phases of the resource recycling system, including planning, design, restructuring, organization and response—to preserve environmental quality for future development goals. Still, different technical resource recycling practices in urban or suburban environments are needed to address the economic features, ecological conservation, and social conventions toward sustainable development. This SI aims to collect academic models/methodologies/practical solutions that support an appropriate SSW to handle the huge volume of generated waste, provide high economic benefits, and stabilize the local social situation.

In addition, SSWM plays fundamental roles in utilizing resources while producing new commercial prospects by renovating new resource-management practices and encourages private-sector participation by generating more employment and business opportunities. Proper SSWM is important to its TBL impact, and different approaches are necessary to reflect the attributes of human consumption and guarantee the sustainability of the biological environment through appropriate waste management activities. Waste management processes involve basic waste management such as assortment, transport, treatment, and disposal. The current literature is lacking when it comes to effectively and efficiently enhancing resource recycling and depends on internal resources but also requires resources from outside stakeholders. This Special Issue seeks advanced research to enhance or guide sustainable solid waste management and resource recycling.

Interesting topics include but are not limited to:

  • Systematic frameworks for sustainable solid waste management and their influential attributes to resources recycling;
  • A proper practical approach or method for promoting sustainable solid waste management and resource recycling;
  • Innovative approaches for sustainable solid waste management and resource recycling;
  • Novel theories and methods for sustainable solid waste management and resource recycling;
  • Decision making on sustainable solid waste management and resource recycling.

Developing sustainable concrete with less ordinary Portland cement is a growing issue in the construction industry. Incorporating industrial by-products (such as fly ash or slag) or municipal solid wastes (such as waste glass or recycled concrete aggregate) into the concrete becomes an effective way to reduce the consumption of natural sources and carbon dioxide emission if a proper mix design is provided. The present study examines the influence of the combined use of off-ASTM Class F fly ash (FFA) and waste limestone powder (LSP) on flowability, compressive strength, and expansion characteristics of mortar mixtures containing waste glass sand (WGS). FFA and LSP were used as cement replacement while WGS was used as partial reactive siliceous river sand replacement. Material variables included different WGS replacement ratios (25%, 50%, and 75%) with river sand, LSP contents (25%, 50%, and 75%), FFA contents (15%, 30%, and 45%), and different combinations of FFA-LSP (15–10%, 15–15%, 15–30%, and 15–35%). It is shown that the single use of FFA or LSP reduces both compressive strength and flowability of mortar mixture as its replacement level increases. However, mixtures combined with FFA and LSP provide higher or comparable strength to the single LSP or FFA mixture. For the expansion characteristics due to alkali-silica reaction, the single-use of more than 30% FFA or 75% LSP has less than 0.1% expansion, which is a non-reactive aggregate criterion based on the C1260/C1567 when the test period is extended to 56 days. Moreover, the combination of FFA and LSP has a considerable reduction in expansion rate compared to the single FFA or LSP mixture. Full article

Municipal solid waste (MSW) management has become a problem in China, mainly since there is no uniform standard for MSW management charges, causing conflict between local residents and the government. An intelligent garbage sorting system (IGSS) is an effective sorting approach for MSW management. To explore the predictors of local residents’ willingness to pay (WTP) for the IGSS, this study applied an extended theory of planned behavior (TPB) model by adding an antecedent environmental concern (EC) prior to the main predictors of the TPB model (attitudes, subject norms, perceived behavioral control). The WTP of Beijing residents for MSW management and the determinants of WTP were analyzed. The specific amount of WTP was predicted by a contingent valuation method (CVM) in an online questionnaire, and the mean WTP was estimated to be USD 49.93 per household per year. The results showed a positive connection between EC and residents’ WTP, and most of the participants were willing to pay for the IGSS for MSW management. Full article

Recycling resources from waste can effectively alleviate the threat of global resource strain. Due to the wide variety of waste, relying on manual classification of waste and recycling recyclable resources would be costly and inefficient. In recent years, automatic recyclable waste classification based on convolutional neural network (CNN) has become the mainstream method of waste recycling. However, due to the receptive field limitation of the CNN, the accuracy of classification has reached a bottleneck, which restricts the implementation of relevant methods and systems. In order to solve the above challenges, in this study, a deep neural network architecture only based on self-attention mechanism, named Vision Transformer, is proposed to improve the accuracy of automatic classification. Experimental results on TrashNet dataset show that the proposed method can achieve the highest accuracy of 96.98%, which is better than the existing CNN-based method. By deploying the well-trained model on the server and using a portable device to take pictures of waste in order to upload to the server, automatic waste classification can be expediently realized on the portable device, which broadens the scope of application of automatic waste classification and is of great significance with respect to resource conservation and recycling.

This study contributes by developing a set of household waste separation (HWS) attributes to address waste mishandling and to enhance waste separation intentions in households. In Mongolia, a lack of waste separation at the household level needs to be addressed to improve municipal solid waste management systems. However, prior studies have not established attributes in a hierarchical structure, nor do they understand their cause-effect interrelationships. First, the fuzzy Delphi method (FDM) was used to screen out the unnecessary attributes in qualitative information. The fuzzy decision-making trial and evaluation laboratory (FDEMATEL) was then applied to understand the hierarchical structure of the attributes and their cause-effect interrelationships. The study identifies a valid set of attributes consisting of five aspects and 17 criteria under uncertainties. A hierarchical framework consisting of environmental attitudes, social norms, perceived behavioral control, perceived convenience, and persuasive communication is provided. The findings reveal that persuasive communication and environmental attitudes are causal group aspects. Furthermore, persuasive communication has a strong causal impact and higher importance in improving HWS intentions, and it leads to perceived convenience and behavioral control. For policymakers, credibility of information, knowledge and information, awareness of consequences, willingness to sort, and perceived policy effectiveness are the key causal criteria for enhancing HWS intentions. Theoretical and practical policy implications are discussed. Full article
