Abstract: The study explores cost implications of alternate use of some agricultural wastes for energy use through refuse derived fuel (RDF) from solid agricultural wastes. The economic feasibility of RDF from agricultural wastes in Durban was carried out. The analysis was performed by determining some economic indices. The total capital cost obtained was $5.70 million while the total revenue from the system was $13.49 million for the entire project life of 13 years (360,000 Kg of ASW). The quantitative economic indices obtained were NR = $0.12 million, rate of return on investment = 17.1%, PBP = 3.4 years, and NPV = $3.53. The total capital cost of $5.70 million is within the budgetary amount allocated for agriculture ($70 million) in the region. The results showed that cost of processing dominated the cost of production but the availability of affordable solid agricultural waste for RDF production minimised the cost of RDF production.
