This plan compares the biological features of a couple of potential feedstock of ethanol and chooses sweet sorghum because of its great adaptability to semi-arid climate and short harvesting cycle. Next, by assessing the technical and economical feasibility of a local small-scale ethanol plant and bringing forward integrated solutions throughout the entire supply chain from the feedstock production to the retail of ethanol fuel products, this business plan indicates that ethanol cooking fuel and stoves can substitute prevalent fuel-wood and three-stone fire cost-effectively. The local production of ethanol can yield income benefits to local farmers by purchasing local feedstock, healthy benefits to local residents, especially women and children, and job-creating benefits to local communities by involving retailers, delivers and farmers into this business.
