Abstract :
In this research paper, a marine seaweed, Cauler papelata obtained from Gulf of Mannar was investigated
for bio-diesel production. Biodiesel was prepared from Cauler papelata and its fuel properties were analyzed
according to ASTM D6751 standards. Algal oil was extracted by solvent extraction using chloroform/methanol
system. The extracted algal oil was further transesterified using methanol and catalyst. Various catalyst systems
comprising of commercial catalysts were compared with prepared eggshell catalyst. The eggshell catalyst was
prepared by calcination of waste eggshells at various temperatures for various time periods. It was found that
biodiesel produced using eggshell catalyst had the same performance compared to that of commercial catalyst.
Moreover, the process produces an environmental friendly biodiesel which is sustainable and cost effective.
