“…Since the none of these technologies are locally produced but are imported into the country, the influence of currency depreciation and fluctuations of the local currency has a high tendency to increase the CAPEX, while the OPEX is strongly influenced by local inflation. This indicates the strong influence of the local economic situation on potential investments [91]. According to the IEA and IRENA, the global cost of new renewable energy plants is expected to reduce in the next decade due to increasing research into cheaper technologies and increasing interest from governments in implementing utility-scale plants.…”

Cities in developing countries continue to struggle with mounting waste management challenges. Within a circular economy framework, energy recovery is mostly nonexistent. Against that background, this study aimed to design and assess the viability of a hybrid waste-to-energy facility for the Greater Accra Metropolitan Area (GAMA) in Ghana by 2030. The proposed plant integrates solar PV, anaerobic digestion and pyrolysis to treat unsegregated municipal solid waste. Three cases were developed for different product combinations. Material flow analysis was performed with STAN software 2.7.101. The results indicate that 1.6 million tons of MSW will be generated, to be potentially converted to 271 GWh of electricity, 6400 tons of hydrogen or 4400 tons of bio-compressed natural gas per year, along with additional products: compost, refuse-derived fuel and bio-oil. The economic indicators show that all cases are potentially viable in terms of the net present value (EUR 397 to 1030 million), internal rate of return (14–22%) and levelized cost of energy (0.11–0.18 EUR/kWh). As such, this study proves that waste to energy is a viable waste management solution for large metropolitan areas, with the potential to supply energy, alternative fuels and material products within a circular economy, though it requires the buy-in of policy makers.

The accelerated path towards the decarbonization of the economy has raised the demand for wind capacity at an exponential rate, at the end of 2021 the global installed capacity reached 840 GW. The useful life of the turbines ranges between 20 and 25 years, which implies that the volume of recyclable material increases proportionally. Currently, 85% of wind turbines are recycled, but the goal is to achieve a recyclability rate of 100%. The blades represent a challenge for the sector, their complex composition of fiberglass, carbon or different resins, make the recycling process difficult. There are different technologies such as mechanical, thermal and chemical recycling that are constantly improving. In fact, the European Union has given priority to the financing of recycling projects, specifically Spain, from the Ministry of Ecological Transition it proposes a line of 150 million euros for different aid programs, including the blade recycling program. In this area, the main objective of this work is to propose an optimal location methodology for blade recycling companies, incorporating economic, technical, political and environmental factors that favor the principles of the circular economy

“…Just like Ali et al [35], Himri et al [37] applied RETScreen software to estimate the energy output and to conduct the economic feasibility of a wind farm in terms of Simple Payback Period (SPP), Internal Rate of Return, Annual Life Cycle Saving, Net Present Value, Year to Positive Cash Flow, Benefit-Cost ratio and cost of electricity production (COE). Odoi-Yorke et al [38] applied the same method; findings reveal that a feed-in tariff (FiT) lower than US$0.15/kWh is not lucrative for wind power development in Adafoah. Furthermore, without financial incentives, the levelized cost of energy (LCOE) from the wind power plant is about US$0.143/kWh.…”

Zambia recently experienced extended hours of load shedding due to reduced hydroelectricity generation attributed to poor rainfall patterns. The inability to meet energy demand has influenced the government to consider alternative energy sources. This study aims to assess the economic feasibility of the eight sites using a 25-turbine layout for a 4 MW generic wind turbine at 130m hub height. An economic evaluation mathematical model was developed to analyze the economic feasibility using net present value, simple payback period, internal rate of return, and levelized cost of electricity (LCOE). The study shows that the Lusaka wind farm was the most economical with 386 GWh energy yield analysis (EYA), wind speed of 8 m/s, NPV of 316 million dollars, SPP of 2.9 years, IRR of 82%, and LCOE of $0.182/ kWh. The results also show that the other seven sites are economically feasible, with Petauke being the lowest. The study's economic sensitivity analysis conducted by varying the average electricity tariff shows that Lusaka was the most financially viable site. Therefore, policymakers should develop cost-reflective feed-in tariff (FiT) schemes and power purchase agreements for the country to have cost-reflective electricity tariffs that will motivate independent power producers to invest in Zambia.
