“…Solid Waste Management (SWM) is a challenging task that contains environmental, socioeconomic, political, and institutional aspects (Debrah et al, 2021). The implementation of solid waste management techniques are depending on the generation and waste characteristics that change with the source (Bowan et al, 2020;Coker et al, 2016).…”
Effective management strategy is required for handling the large quantities of waste produced by various societies/ organizations and waste characterization is essential to prepare this management policy. In this study, solid wastes collected from the combined campus of Chaudhary Charan Singh Haryana Agriculture University (CCSHAU) and Lala Lajpat Rai University of Veterinary and Animal Science (LUVAS), Hisar was characterized through population estimation, field investigations and applying ASTM D5231-92 standard method. In the combined campus, the average quantity of solid waste generation was found to be 1047.1±214.4 kg/day. The whole campus was divided into five structural units and waste composition was determined, mixture unit waste comprised the highest fraction of food 62.13% and polythene 10.8%. The statistical estimation obtained a strong positive correlation of mixture unit waste with residential and markets waste contents, which was 0.995 and 0.997 at p<0.01. The analysis of solid samples showed that the biodegradable part of solid waste may be a better source for composting while some content of non-biodegradable waste can be sold into the market for recycle or reuse purpose. On the basis of solid waste characterization, a set of recommendations were suggested to strengthen the waste management processes for institutions.

Ghana Tamale’s current waste management system is overwhelmed by the growing waste crisis, necessitating the exploration of Waste-to-Energy technologies (WtE) as an innovative solution. This study explores challenges and opportunities for integrating WtE technologies into Tamale’s existing waste management system. Qualitative research identified policy hurdles, financial constraints, social concerns, and institutional weaknesses as key barriers. Conversely, stakeholder collaboration, public education, and capacity building emerged as some success factors. A proposed implementation plan emphasizes feasibility studies, public engagement, public–private partnerships (PPPs), and technology selection based on waste composition. Additionally, a novel framework for WtE integration within a broader Integrated Solid Waste Management (ISWM) system is presented. This framework incorporates waste sorting, recycling, WtE alternatives, and responsible management of residuals. Validation by key stakeholders confirmed the framework’s potential to improve waste management in Tamale. By overcoming identified challenges and implementing the proposed framework, Tamale can achieve environmental sustainability, energy generation, and progress towards UN SDGs 7, 11, and 12. This research offers valuable insights for policymakers and paves the way for a cleaner and more sustainable future for Tamale, potentially serving as a model for other developing cities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
