Without treatment, urban market-generated organic waste is discarded in landfills. This could cause environmental contamination due to leachate. This study aims to develop a novel bio-methane and composting potential framework for evaluating the biogas and compostability of organic waste from the Bantama market in Kumasi. Using novel dashboards, the bio-methane and composting potentials were evaluated, and the Theoretical Biomethane Potential (TBMP) was reported to be between 331.52 and 457.93 l CH4/kg VS for carrot leaves and banana peels, respectively, assuming a biodegradability of 80% for the substrates. Only one of the four conditions for compostability was met by the substrates, indicating that they are not suitable for direct composting. In order to optimize the potential of the waste, an integrated system of anaerobic digestion (AD) and composting was utilized. The proposed plant was profitable since the payback period was less than two years, the Net Present Value (NPV) was greater than one, and the Benefit Cost Ratio (BCR) was greater than one. The anaerobic digester and composting plant are capable of producing 12269392 kWh of electricity and 19585 kg of compost per year, respectively. Lastly, the AD and composting technologies at the Bantama market are cost-effective. The government and municipalities may therefore assist private investors in constructing a waste processing plant.

A novel mechanochemical approach is described for chloride-templated head-to-tail macrocyclization of a pentapeptide and a hexapeptide. This straightforward method allows the solvent-free preparation of cyclopeptides with yields comparable to solution-based approaches without the need for high dilution of the reaction mixture and with significantly reduced reaction times and organic waste amount.

Background: The composition of anaerobically digested sludge is inherently complex, enriched with structurally complex organic compounds and nitrogenous constituents, which are refractory to biodegradation. These characteristics limit the subsequent rational utilization of resources from anaerobically digested sludge. White-rot fungi (WRF) have garnered significant research interest due to their exceptional capacity to degrade complex and recalcitrant organic pollutants.

In this work, UiO-66-l-cys with enhanced adsorption capacity for Hg(Ⅱ) in water was synthesized through a facile two-step partial ligand replacement strategy. The presence of the functional groups significantly enhanced the capacity of the material for Hg(Ⅱ). According to the Langmuir model, the maximum theoretical adsorption capacity was calculated to be 1321.

This article aims to provide a systematic review of the literature on animal biomass and biogas plants through an analysis of externalities and benefits in economic, social, and environmental terms. In recent years, the spread of biogas plants has played an important role, especially in rural areas, generating benefits not only for the individual farm but for entire communities, contributing to the reduction of energy poverty and, at the same time, promoting the production of energy and organic manure. In light of the findings, the study argues that: (a) more public subsidies are needed; (b) the deployment of an appropriate policy mix would encourage the spread of small and medium-sized plants, with a reduction in road transport; and (c) targeted and diversified investments are needed on a geographic-by-geographic basis.
