Waste Animal Bones as Catalysts for Biodiesel Production; A Mini Review

Slaughterhouse waste is considered to be an emerging issue because of its disposal cost. As alternative, it would a great prospect for the bioeconomy society explore new usages these leftover materials. per food safety rules mentioned by EU legislation, all bone generated slaughterhouses ought disposed rendering.
