How Sundrop Fuels

connects biomass with the best resources

There is ample high-quality biomass feedstock available worldwide to supply the Sundrop Fuels biorefineries with renewable material to produce billions of gallons of drop-in biofuels or chemicals per year. Our flexibility in energy source and biomass type allows Sundrop Fuels to economically and efficiently locate plants in most areas of the world.

Importantly, we do not use food-based feedstock, rely on cutting down old growthforests, or divert agricultural land to grow feedstocks for our process. The Sundrop Fuels solution focuses on feedstocks from current commercial sources such as plantation timber and residues from agricultural harvesting.
