Praj Industries Limited is a Biofuels Technology Company with a number of processes and systems for ethanol and biodiesel production to its credit.

NextCAT is commercializing a series of catalysts for use in biodiesel production, developed at the National Biofuels Energy Lab at Wayne State University.

Metro BioFuels aims to develop manufacturing of various vegetable oils into fatty acid methyl esters, commonly known called Biodiesel. The characteristic of their process design that is differentiated per the company is that the conversion takes place in a matter of minutes rather than hours. The process is expected to run both efficiently and economically compared with other similar processes. Further biodiesel aims to reduce CO2 emissions by 78% compared with petroleum diesel due to Biodiesel's closed carbon cycle.

Cellana, formerly HR BioPetroleum, uses marine microalgae to produce feedstocks for biofuels, skin and personal care products, nutritional oils, renewable chemicals and aquaculture and livestock feeds while simultaneously reducing industrial emissions of CO2. In 2007, HRBP and Royal Dutch Shell, the international energy company, formed Cellana as a separate join venture to build and operate a six-acre demonstration facility to grow marine algae and produce vegetable oil for conversion into biofuel. HRBP became the sole owner of Cellana in January 2011.

American Biodiesel, dba Community Fuels, is an advanced biofuel producer. The company produces among the highest quality biomass-based diesel fuels available - which qualifies as an Advanced Biofuel through the Environmental Protection Agency (EPA), and its own fuel standard closely mirrors the requirements of multiple major oil companies and exceeds the Federal fuel standard (ASTM Standard).
