Biomass energy has the potential to act as a sustainable and environmentally friendly alternative to fossil fuels and help achieve net-zero emissions in the near future. This study proposes an economically feasible method to enhance biogas efficiency by co-digesting cow dung (CD), food waste (FW), rice straw (RS), with the addition of Coconut husk Bio-Char (BC). The present research aims to study the variation in the biogas yield from biochar addition by monitoring the alteration in the influential parameters such as pH, temperature, total solids (TS), volatile solids (VS), volatile fatty acids (VFA), and carbon to nitrogen ratio (C/N). The biochar addition stabilized both pH and temperature due to its intrinsic properties by transforming intermediates like H<sub>2</sub>S and CO<sub>2</sub>. It also significantly increased the VFA accumulation and degradation attributed to the buffering ability of the biochar. The methane yield of blends with biochar was significantly higher than that of the blends without biochar. The mixture CD 30: FW 50:RS 20 containing biochar showed a peak methane yield of 165.08 mL. The statistical model developed using response surface methodology (RSM) predicted the methane yield with an accuracy of 99.07 % and a statistical significance level of 0.05. The accuracy of the RSM model was validated by comparing it with the existing Gompertz kinetic model.

Based on the EU annual production of canned seafood products, it was estimated that 511 k tonnes of by-products could be available. The valorisation of such by-products face challenges as their variability and degradation and, although it is a low-cost raw material, logistics are required to collect them.

The experimental design was a Completely Randomized Design, consisting of five treatments. The approaches entailed incorporating coffee pulp-derived biochar into soil at proportions of 0, 2.50, 3.75, 5.00, and 7.50 % of the soil’s weight. The characterization of biochar was analyzed by scanning electron microscope (SEM), Energy Dispersive X-Ray Spectroscopy (EDS), and Fourier-transform infrared spectroscopy (FTIR). Results showed the coffee pulp biochar contains various pore’s structure and high spectra of –C–O stretching functional group. High carbon (C) content (66.60 %) and abundance of exchangeable K were detected in as-made biochar. The analysis of basic soil nutrients after treatment with coffee biochar revealed statistically significant differences (<em>P</em> ≤ 0.05) in available P exchangeable K, exchangeable Mg (highest at 7.5 %), exchangeable Ca (highest at 5 %), and %SOM (increased at 3.75 %). Notably, soil microbial respiration (SMR) and dissolved organic carbon (DOC) increased proportionally with the percentage of coffee biochar used. Conversely, microbial biomass carbon (MBC) decreased as the dosage of coffee biochar increased. Microbial analysis revealed reduced fungal counts (max 68 % at 5 % biochar) and increased cellulase-producing (39 %) and phosphate-solubilizing (14 %) microorganisms at 2.5 % biochar compared to control. The correlation matrix has evidenced significant exchangeable K content in coffee pulp biochar demonstrating the positive correlation with soil biological improvement.

Using a systematic narrative review methodology, peer-reviewed articles, government reports, and grey literature were analyzed to assess degradation patterns, restoration interventions, and implementation challenges. Empirical findings indicate that major rivers, including the Pra and Ankobra, are heavily polluted with mercury and cyanide, exceeding WHO safety limits. Deforestation rates in mining zones have significantly reduced carbon sequestration, contributing to climate vulnerability. Restoration strategies—such as afforestation, biochar application, and phytoremediation—have had mixed success due to weak policy enforcement, financial constraints, and low community engagement. The novelty of this study lies in its integration of global best practices, such as China's policy-driven land reclamation and Brazil's agroforestry-based restoration, into a localized framework for sustainable rehabilitation in Ghana. The findings emphasize the need for adaptive restoration techniques, stronger regulatory mechanisms, and community-inclusive approaches to enhance ecological resilience. Limitations include the reliance on secondary data, highlighting the need for field-based validation of restoration outcomes.

Furthermore, electronic waste (e-waste) increases significantly, raising additional environmental concerns. This study develops a new closed-loop supply chain (CLSC) logistics model to tackle these issues. This CLSC model is designed by integrating a new production approach known as rolling planning production schedules (RPPS). The main feature of the RPPS is that real market demands dictate the manufacturing quantity at the factory. Additionally, RPPS lead time is included in developing the proposed CLSC model, replacing simultaneous flow systems with periodic flow systems of goods from one stakeholder to its successive stages. Also, <em>K</em>-means algorithm was applied to cluster stores for efficient shipment. Afterward, a second alternative model was also developed to compare the performance of the suggested model, where a fixed production volume manufacturing approach was utilized instead of the RPPS. The findings indicate that the proposed model yields better results than the second alternative. Moreover, by adjusting the model's parameters, a sensitivity analysis is conducted to confirm the model's robustness and the reliability of the results.
