Essential Biodiesel Production Equipment: A Comprehensive Overview

Before we explore the essential biodiesel production equipment, we should know the biodiesel is a good alternative to fossil fuels as its greenhouse gas (GHG) emission level is lower. It burns well when mixed with diesel and used for commercial purposes. It is a prime pillar for achieving the energy transition we are aiming for.

Biodiesel can be procured from used cooking oil (UCO), non-edible vegetable oils, animal fat, restaurant grease, etc. Its profitability and economic impact on the energy transition can bring a big change in the Indian industrial sectors.
