Special Issue Information

Dear Colleagues,

In the modern world, the management of liquid and solid industrial wastes present in the environment in massive quantities has remained one of the most intractable problems. Diverting the harmful anthropogenic waste fluxes from landfills is a significant contributor to environmental protection and climate change mitigation. Making use of waste resources is also a critical part of how we tackle the worldwide overconsumption of scarce virgin resources. Different possible ways forward in waste management would thus make significant progress in the circular economy, sustainable development, and zero waste goals. Integrated waste management is therefore a comprehensive goal with broad scope and global coverage. For this purpose, it is essential to track trends in the quantity, composition, and effects of various solid waste resources from the major industries. This will provide insight into the efficiency with which nations can reutilize (reuse/recycle) such waste materials and resources, and provides a means to better understand the effects of solid wastes on human health and ecological condition. Promoting the sustainable use of industrial solid waste resources must be further supported by developing the rationale and different assessment tools for taking a holistic approach towards solid waste management. These tools are designed to draw conclusions and make recommendations that assist decision makers and practitioners in developing sustainable solutions for local waste management problems.

This Special Issue on “Solid Waste Management and Environmental Protection” focuses on the recent developments in this field, and aims to bring together high-quality research articles on the various aspects of sustainable solid waste management, covering both the current state and remaining challenges. We welcome scientific manuscripts or reviews that address different aspects of waste management, such as waste reduction, reuse, and recycling; energy recovery; and land reclamation. Research into the various assessment and modeling tools for waste management based on life cycle assessments, multi-criteria decision-making, cost–benefit analysis, and risk assessment is also included within the scope. Comprehensive research into industrial waste characterization by measuring and estimating the quantity, composition, and effects of various industrial solid waste resources is also covered.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Advanced solid waste recycling technologies and resource recovery systems;
  • Environmental LCA for solid waste management;
  • Economic opportunities from solid waste management;
  • Situation, challenges, and solutions of policy implementation regarding solid waste management;
  • Case studies addressing specific waste management issues.

We look forward to receiving your contributions.

Two-phase olive pomace is a byproduct of the olive-oil extraction process that is sometimes processed further to recover more oil. During pomace oil production, especially in the early stages of olive processing, odours can be produced. These odours are a serious nuisance, especially in and around the processing facilities, as well as for nearby communities. These odours can be strong and unpleasant, and they may result in various issues, including environmental concerns. Thus, in this paper, the effect of storage and drying on the composition of two-phase olive pomace was investigated. Several physicochemical and instrumental analyses were performed, and it was concluded that the structural elements of pomace are not the ones that are affected during storage and drying. Storage and drying mainly impact the oil content of pomace, leading to an acidity increase and to the production of odorous oxidation compounds. Volatile acids, methyl, and ethyl esters are released into the atmosphere, thus causing serious environmental nuisance. Full article

Mining waste is generated in vast quantities globally, which can have negative environmental consequences. This study highlights the utilization of iron ore mining waste as feedstock material in the preparatory step of an indirect aqueous mineral carbonation for carbon sequestration. The role of reactive cations (Ca2+, Mg2+, and Fe2+) was investigated in view of their elution behavior to improve carbonation efficiency. An elution experiment was carried out for the divalent cations using different acids (oxalic, HCl, acetic, and formic acid) at different concentration solutions (up to 1.5 M) and times (up to 100 min) at ambient temperature. The initial analysis confirmed the presence of divalent cations in the sample. The elution approach at ambient temperature resulted in the elution efficiency of Fe2+ (30.4%), Mg2+ (54%) using oxalic acid, and Ca2+ (98%) using HCl at a relatively short time between 50 and 100 min. It was found that for the iron ore mining waste, oxalic acid and HCl were best suited as elution agents for the Fe2+ and Mg2+, and Ca2+, respectively. The CO2 sequestration potential was calculated to be 131.58 g CO2/kg residue. A further carbonation step using a complexing agent (1,10 phenanthroline) confirmed the formation of siderite and magnesite along with phenanthroline hydrates. Findings have shown that the indirect mineral carbonation of the iron mining waste with complexing agent might improve carbonation efficiency, thus indicating that this material is useful for long-term carbon capture and storage applications.
