Biodiesel is a non-toxic renewable energy source that is gaining attention globally owing to
its direct applicability in preexisting engines without any modification. Various technologies …

In this study, a heterogeneous catalyst prepared by pyrolysis of waste cork (Quercus suber)
was used for the transesterification of waste cooking oil (WCO). Physicochemical properties …

Versatile bio-derived catalysts have been under dynamic investigation as potential
substitutes to conventional chemical catalysts for sustainable biodiesel production. This is …

Coal fly ash-zinc oxide composite (CFA/ZnO) was developed, characterized and applied as
a catalyst in the transesterification of used cooking oil (UCO) with methanol to obtain …

The present paper is focused on the development of a new environment-friendly
methanolysis catalyst completely based on waste materials: lignite coal fly ash and chicken …
