Biodiesel production from grease trap waste and its purification using activated biochar derived from woodchips biomass

Depletion of non-renewable fossil fuels and growing environmental awareness have attracted extensive research worldwide towards biodiesel. It is clean, safe, biodegradable, and renewable. Presently, grease trap waste (GTW) appears to be an alternative feedstock for biodiesel production, while woo...
