Synthesis of bifunctional nanocatalyst from waste palm ...- washing powder bulk biodiesel production from waste cooking ,The waste cooking oil (WCO) generally consists of high triglycerides content (85%), free fatty acids (FFA, 15%), moisture and solid residue. Previously, the biodiesel production from WCO was catalyzed with a homogeneous catalyst by two-step esterification–transesterification, where esterification is to reduce the FFA prior to transesterification reaction. Thus, the two-step …Sustainable biodiesel generation through catalytic ...If waste cooking oil is the operational feedstock for producing biodiesel at a lower price, a large amount of waste oil available is adequate for sustainable biodiesel production. Waste yields, i.e. , lignocellulosic feedstocks and inedible unwanted oils such as waste cooking oil or vegetable scums, are the unavoidable consequence of edible oil intake as a usual ration of the human diet.

Biodiesel can be made from waste cooking oil, but we don’t want to take one waste product (cooking oil) and create another waste product (glycerin). Therefore we refer to the glycerin produced during the biodiesel reaction as a “by-product”. By-products retain both financial and environmental value that we can capture through other chemical processes. Biodiesel …
