Viridos develops and commercializes genomic-driven solutions to address global energy and environmental challenges. It builds a platform for low-carbon-intensity biofuels that can reduce greenhouse gas emissions from aviation, commercial trucking, and maritime shipping. The company was formerly known as Synthetic Genomics. It was founded in 2005 and is based in La Jolla, California.

WHEB Biofuels Limited aims to be a biofuels producer that also invests in biofuels technologies

Biodiesel Technologies offers biodiesel processor equipment

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

Greenline Industries manufactures biodiesel production equipment.

Green Tech America, Inc. (GTA) is in the business of developing and commercializing an yeast-based cellulosic ethanol technology that was pioneered by Dr. Nancy Ho at Purdue University. Cellulosic biomass (corn cobs and stover, wheat and rice straws, wood, grasses, municipal paper wastes, etc) is renewable and abundantly available in the United States. The application of cellulosic ethanol to transportation will help solve the company's Nation's energy problems, strengthen the company's economy, save the company's environment, and have a beneficial impact on the company's society. GTA is dedicated to making the production of cellulosic ethanol a reality in this country. The goal of GTA is to establish a cutting-edge company that supports and collaborates with ethanol producers to make the production of cellulosic ethanol a highly profitable business. Based on the Cellulosic Ethanol Yeast Technology developed by Dr. Ho and her colleagues at Purdue University, GTA will optimize the technical details and establish a blueprint for cellulosic ethanol production. The "blueprint" will then be licensed to other ethanol producers throughout the US and around the world to establish franchises for cellulosic ethanol production.GTA will provide cells, enzymes, chemicals, project management and technical support to the cellulosic ethanol producers, particularly to the numerous newly established corn-ethanol farmer-owned plants. The goal is to transform such plants to produce both corn- and cellulosic-ethanol. However, GTA's main business at the present time is to help the Purdue researchers engineer the yeast to produce important industrial products that can be produced alone or co-produced during ethanol production. Most importantly, the resulting yeasts can efficiently produce these co-products during the production of ethanol using sugars from both grain and cellulosic biomass as feedstocks.The Saccharomyces co-production technology to be marketed by GTA will make both the current grain-to-ethanol and the emergent cellulosic ethanol process more cost effective and profitable. The first generation of co-products that GTA plans to produce are substances important for animal feed, for the detergent industry, for the paper and fabric industry, as well as others. In addition, GTA will also market high valued products and residues, such as yeast extracts, from the yeast cells. More importantly, GTA will generate a range of other products produced from renewable resources for sustainable growth. GTA will also provide the R&D as well as the technical consultants for all small corn- or cellulosic-ethanol producers.
