Special Issue Information

Dear Colleagues,

Industrial solid waste, including mining slag, sludge, fly ash, and waste residues, is widely produced in the industries of mining, energy, chemical engineering, and machining. Some industrial solid waste containing hazardous elements is usually listed as hazardous waste in many countries and regions. The treatment and management of industrial solid waste are not only associated with ecological and health risks, but are also connected with the sustainable development of factories, countries, and the earth. Therefore, with great public awareness of the implications of industrial solid waste on environment safety and sustainable development, there has been increasing interest in the occurrence, characteristics, and management of industrial solid waste, as well as in the development of technologies to treat industrial solid waste.

In raising awareness around the importance of industrial solid waste management and treatment, we are pleased to announce the launch of a new Special Issue with the theme of “Industrial Solid Waste Management”. The topics of interest include the following scientific issues:

1) Source, processes, and health risk of industrial solid waste from all industries;

2) Environmental chemistry behaviors of hazardous elements during the storage and treatment process of industrial solid waste;

3) Novel technologies to recycling, volume reduction, detoxification, and final disposal of industrial solid waste;

4) Management measures and regulations of industrial solid waste.

Hence, this Special Issue titled “Industrial solid waste management” of Sustainability invites the submission of papers from leading experts on the latest facts surrounding theoretical foundations and management strategies.

To study the heterogeneity and local heterogeneity of gangue particle size distribution (PSD) under ball milling, gangue from northern Shaanxi coal mine was taken as a research object. The multifractal pattern of PSD and the variation trend of characteristic parameters of gangue under different ball-to-gangue ratios and grinding times were analyzed by introducing multifractal theory and microscopic research methods such as laser particle size analysis and scanning electron microscopy. The results show that the multifractal characteristics of the gangue particle size distribution with different ball-to-gangue ratios and grinding time periods demonstrate obvious changes. When the ball-to-gangue ratio is 3~9, the multifractal parameters D(0), D(1), Δα, and Δf all show linear changes with grinding time. It is demonstrated that due to the phenomenon of particle agglomeration during ball milling, the multifractal characteristics of the particle size distribution of the gangue changes significantly when the ball-to-gangue ratio is 12~15. Furthermore, the results indicate that with the increase in time, D(0), Δα, and Δf show a trend of decreasing first and then increasing, and D(1) and D(1)/D(0) show a trend of first increasing and then decreasing, and both reach their extreme values at 30 min.

Landfills are an effective way to dispose of waste and appropriate landfill sites can lessen environmental damage during waste treatment. Solid waste landfill site (SWLS) selection has received much attention in the area of multi-criteria decision-making in recent years. However, the uncertainty and complexity of the SWLS selection make it a significant challenge for decision makers (DMs). Since single-valued neutrosophic (SVN) sets have the great advantage of handling complex problems with uncertain and inconsistent information, this paper aims at offering a site planning strategy under the SVN environment. For the SWLS selection problem with interrelated factors, the Schweizer–Sklar power Bonferroni mean operator is first created, which not only considers the possible correlations among attributes but also reduces the adverse effects of anomalous assessment information on decision results. Then, a multi-criteria analysis framework based on the aggregation operator is proposed and then applied to a real-world SWLS selection. DMs can flexibly adjust the parameters in this model to achieve a preferred SWLS that integrates economic, environmental, and social perspectives. The consistent results obtained from the comparative analysis highlight its benefits for selecting proper SWLSs. Full article

The change law of alkaline steel slag cementitious activity was investigated by mechanical excitation, alkaline excitation, and salt excitation methods. The effect of grinding time, chemical activators, and content of steel slag on the properties of cement replaced by steel slag was studied. The hydration products of cement replaced by steel slag were analyzed by XRD and SEM. The results show mechanical excitation can effectively improve the particle size distribution and cementitious activity of steel slag. The best mechanical properties are obtained when grinding for 20 min and adding 10% steel slag. Chemical excitation can further improve the cementitious activity of steel slag based on mechanical stimulation. The optimal mechanical properties are obtained when the dosage of sodium hydroxide is 1.0%, the dosage of early strength agent is 2.0%, and the dosage of steel slag is 25%. The main hydration products of cement replaced by steel slag are calcite (CaCO3), calcium hydroxide (Ca(OH)2), dicalcium silicate (Ca2SiO4), and C-S-H gel. The microstructure presents a fibrous network structure, laying the foundation for improving mechanical properties. Full article
