India’s Central Railways move forward with biodiesel production but lack feedstock

In India, Central Railways has produced 20,000 liters of biodiesel from edible oils during its first year producing the fuel. The state-owned company would like to boost production but says there is a lack of available feedstock supply. so will soon begin a program to collect used cooking oil from restaurants that it hopes will be donated to the biofuel program. CR has concerns, however, about edible oils that have been used more than once because it says the viscosity properties changes and are no longer good for blending with diesel.
