| Zusammenfassung: | 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 |
