Production of Biodiesel from eggshells
Used vegetable oil can become a relevant contaminant if delivered to rivers and auriferous areas.
The biodiesel is green fuel produced from various sources. At NARO biodiesel is produced by converting vegetable oil into fuel. Re-use and overuse of vegetable oils results into production of compounds that can lead to cancer in human beings. Poor exposure of such oils is also a municipal catastrophe as the highly vicious oil can clog water ways and limit the flow water causing clogs and affecting municipal waste management. As such conversion of waste oil into bio diesel alleviates its overuse, provides for better waste management practices, while generating fuel that is environmentally sound. Bio diesel can be used to make animal feed making machines, small house generators, walking tractors for clearing the land.
This technology involves the production of calcium based catalyst from egg shells and use of Cassava waste, derived from ethanol and methanol, producing biodiesel. The breakdown of this used oil, in the presence of such catalyst, produces biodiesel while the residues include glycerol-based compounds that can be further processed into glycerine or used in production of other high energy compounds such as briquettes.
Market deployment considerations
High cost for used vegetable oil and competition of the waste oil with re-users (especially roadside vendors).
