Special Issue Information

Dear Colleagues,

Rapid urbanization and industrialization are leading to an immense increase in waste production all over the world. Most of the generated municipal and industrial wastes are sent to landfill or dumped in the open, causing serious air, water, and soil pollution to natural ecosystems. Recently, the concept that “waste is a misplaced resource” has been proposed. This notion suggests that waste should be preserved as a resource and utilized for efficiency, resulting in lower carbon emissions and the implementation of clean and green production activities. Sustainable waste management is an innovative solution to the issue of waste and wastewater management, and can help us reach the global goals of waste reduction, reuse and recycling.

However, due to the complex physical and chemical properties of waste, it can be technically difficult to recycle or recover useful ingredients. Additionally, concerns of the public regarding the reliability and environmental safety of this form of waste recycling also hinder the development of resource recycling technology.

The present Special Issue aims to collect innovative works of research that highlight different perspectives on sustainable waste management. This Special Issue welcomes high-quality contributions in the areas of:

  • The physicochemical and biological properties of solid waste and wastewater;
  • Technologies for solid waste disposal and recycling;
  • Wastewater treatment and energy recovery;
  • Waste recycling towards carbon neutrality;
  • The environmental compatibility of recycling waste;
  • The life cycle assessment of recycled waste;
  • Optimal resource management strategies for waste recycling;
  • New sustainable policies and strategic frameworks.

The safe disposal of hazardous waste from zinc hydrometallurgy, such as jarosite residue, is crucial for the sustainable development of the industry. The chemical, structural and morphological properties of jarosite residue from zinc smelting were studied by a combination of various characterizations, and environmental stability was evaluated using the toxicity characteristic leaching procedure (TCLP), Chinese standard leaching tests (CSLT) and long-term leaching experiments (LTLE). Phase composition analysis revealed that zinc ferrite and sodium jarosite were the main phases present in the jarosite residue. TCLP and CSLT analyses indicated that the Zn and Pb contents exceeded their respective toxicity identification standards by more than 30 times and 8 times, respectively, exceeding the threshold values of the standard. The LTLE results demonstrated that Pb concentrations continued to exceed the standard limits, even after long contact times. This study has paramount significance in the prediction of jarosite residue stability and the evaluation of its potential for secondary environmental pollution. Full article

Reducing carbon emissions is crucial for humanity. Recently, the International Maritime Organization has set carbon emission quotas to limit the extensive carbon emissions from the marine industry. This paper examines how shipbuilders can adopt the rebuilding of decommissioned ships to reduce carbon emissions and also make more profits. Incorporating the carbon emission quota policy, we formulate the dynamic rebuilding model of decommissioned ships and derive the optimal rebuilding and pricing control strategies for the shipbuilder. We investigate the evolutionary dynamics as well as the impact of carbon quotas and carbon emission savings on shipbuilder’s strategies. The study’s findings suggest that shipbuilders have the potential to improve their profitability while also contributing to energy conservation and emission reduction. This can be achieved through the implementation of technological innovations aimed at reducing carbon emissions from their production activities. The government has a crucial role to play in regulating and managing shipbuilders. In cases where the cost per unit of carbon quota is deemed excessively high, it may be necessary to establish appropriate regulations that prevent shipbuilders from directly benefiting from the trade of carbon quotas. This approach can also help ensure the positive development of the carbon trading market. Full article
