摘要：To reduce environmental degradation and improve energy security in Ghana, waste-to-energy (WtE) technologies will play a key role. This paper assesses the feasibility of municipal solid WtE technologies in Ghana using Accra as a case study. Technical feasibility, economic feasibility, and barrier analysis have been carried out to assess the feasibility of municipal solid WtE conversion technologies. Data from the Environmental Protection Agency of Ghana is used for the techno-economic analysis and a face-to- face interview is used to assess the barriers to the deployment of WtE technologies in the country. A power generation potential (PGP) of 530 kW/tMSW and an energy recovery potential (ERP) of 41.68 kWh/tMSW is recoverable from the waste in Accra when biochemical energy conversion is applied and a PGP of 1320 kW/tMSW and an ERP of 106 kWh/tMSW is recoverable when thermochemical energy conversion is applied. The economic analysis showed that the initial investment cost of WtE technologies is high, however, implementation of this technology is likely to have a good payback period of 8 years for the thermochemical processes and 4 years for the biochemical process. Additionally, the net present value and the sensitivity analysis conducted shows that WtE technologies are economically feasible in Ghana. The barrier analysis suggests that the main hindrance to the deployment of WtE technologies in Ghana is the high upfront cost.
