A sustainability study of the processing of kitchen waste as a potential source of biofuel: Biodiesel production from waste cooking oil (WCO)

One of the most concerned components in world’s food system challenges is waste, and it particularly a critical issue developed countries. Waste cooking oil (WCO) one liquid wastes that are recyclable. A proper recycling practice WCO helps to reduce adverse impact on environment can be reused by converting into industrial products such as biodiesel soap. With rising cost crude global market depletion conventional fuel, world also need alternative fuel fulfil energy demands. This paper studies potential source biofuel transesterification process. The acid value determined using standard titration method, which, if percentage FFA more than 2%, which needs undergo pre-treatment Sodium hydroxide used catalyst methanol reacting alcohol transesterification. characteristics produced were tested compared with specification biodiesel; ASTM D6751 EN 14214. From experiment conducted, 90% yield obtained from waste oil. properties undergoes washing process, value, density, kinematic viscosity, cloud pour points have values typically close 14214 standards, seen Sample 1. Producing alternatives disposing these gives beneficial impacts environment. Since biodegradable, economical, environmental friendly always available, economic feasibility production viable.
