Special Issue Information

Dear Colleagues, 

The continuous growth of waste streams generated by urban, industrial, and agricultural activities poses significant environmental and sustainability challenges. Addressing these issues requires the development of advanced environmental technologies that integrate chemical, physicochemical, and biological approaches to ensure effective waste treatment, pollution mitigation, and resource recovery. This Special Issue aims to provide a broad and interdisciplinary platform for innovative research on sustainable waste and resource management, covering solid waste, wastewater, industrial residues, and complex waste matrices. Particular emphasis is placed on advanced chemical and physicochemical treatments, their integration with biological processes, and their contribution to circular economy strategies. This Special Issue welcomes original research articles and high-quality review papers. Topics of interest include, but are not limited to, advanced environmental technologies for waste management, adsorption-based technologies and novel sorbent materials, chemical and advanced oxidation processes, physicochemical treatment and separation methods, biological and biotechnological processes for waste conversion, circular economy approaches, sustainable waste valorization, and environmental remediation.

We look forward to receiving your valuable contributions.

The accumulation of agricultural residues represents a major environmental challenge in developing countries, particularly in tropical regions where inadequate waste management contributes to environmental degradation. Vermicomposting has emerged as a sustainable technology capable of transforming organic waste into nutrient-rich fertilizers through the combined activity of earthworms and microorganisms. This study evaluated the influence of different agricultural residues on the physicochemical properties of vermicompost under tropical conditions in Mozambique. The experiment was conducted at the experimental field of the Catholic University of Mozambique—Faculty of Engineering in Chimoio district, using three substrate types: leguminous residues (T1), cereal residues (T2), and horticulture residues (T3). Each treatment was combined with poultry manure in a 1:1 ratio. Vermicomposting was carried out using Eisenia fetida. Because treatments were not independently replicated, results are presented as descriptive physicochemical characterizations (means ± SD of analytical subsamples). All treatments produced vermicompost with physicochemical characteristics consistent with established maturity criteria: pH 8.03–9.07, moisture 50–76%, and electrical conductivity 527–939 µS/cm, C/N ratio ranged from 15.56 to 20.19, total nitrogen ranged from 1.2 to 1.8%, phosphorus from 0.6 to 0.9%, and potassium from 1.1 to 1.5%. T1 (leguminous residues + poultry manure) showed the highest nutrient concentrations and lowest C/N ratio. These descriptive findings suggest that vermicomposting represents a promising strategy for recycling agricultural residues into vermicompost with characteristics consistent with established maturity criteria, highlighting the importance of substrate selection. The findings suggest that vermicomposting is a promising strategy for sustainable waste management and soil fertility improvement in tropical smallholder systems. Full article
