Utilization of waste crab shell (Scylla serrata) as a catalyst in palm olein transesterification

Aquaculture activity has increased the population of crab, hence increasing the generation of related wastes, particularly the shell. In addition, the number of molting process in crabs compounds further the amount of waste shell generated. As such, in the present work, the application of the waste...
