Joint Venture for Animalwaste Sludge to Biodiesel

Veridium Corporation and Mean Green BioFuels are planning a joint venture on the conversion of fats from livestock and poultry facility wastes into biodiesel fuel.

Veridium and Mean Green are both portfolio companies of GreenShift Corporation. (Greenshift holds about 65% of Veridium.) GreenShift is transferring its stake in GreenShift Industrial Design Corporation (GIDC), the developer of the Dissolved Air Flotation (DAF) sludge processing technology that Veridium will use in the JV (earlier post), to Veridium.

The proprietary sludge processing technology now owned by Veridium reduces the volume of DAF sludge by 80% while recovering the majority of the animal fats contained in the sludge—fats that can be used as biodiesel feedstock.

The USDA requires facilities that process the 100 million pigs, 35 million cattle, 1.6 billion turkeys, and 8 billion chickens slaughtered each year to use large volumes of clean water to continuously rinse the meats as they are cut and packaged.

The derivative large volumes of water contain extremely high levels of protein and fat. These nutrients are removed from the wastewater using conventional but efficient wastewater processing methods. This results in a cleaned wastewater and a concentrated sludge, which is called Dissolved Air Flotation (DAF) sludge. The poultry industry alone generates in excess of 2.5 billion pounds—more than 63,000 tanker loads—per year of DAF sludge.

Veridium’s technology enables livestock and poultry processing facilities to dramatically reduce the volume of sludge they are shipping and disposing, resulting in reduced costs and increased profitability for livestock and poultry processing facilities. Poultry processing facilities alone will generate in excess of 50 million gallons—10,000 tanker-loads—per year of this fat when utilizing Veridium’s process, and this fat can be converted into biodiesel fuel.

Veridium is a publicly traded industrial waste recycling company and holds the rights to more than a dozen proprietary universal processing, water purification, emissions control and waste recycling technologies.

Mean Green’s business model is currently based on the production of biodiesel from four main feedstocks:

  • Soy bean oil;

  • Corn oil extracted from ethanol facilities using Mean Green’s corn-oil extraction technology;

  • Animal fats procured from rendering operations;

  • Animal fats derived from dissolved air flotation wastewater sludges.

The state of Missouri shut down the turkey guts plant because they failed to eliminate the stench.


The Carthage plant is still operating, they were getting complaints right and left but they seem to have lessened the putrid smell a bit.
I still can't figure out how the House and Senate managed to pass that bio-fuels credit and NOT allow CWT to qualify.

comScore is proud of its partnership with Trees for the Future, and the 3 Million trees (link to that have been planted as a result of this partnership so far. Since 1988, Trees for the Future has helped thousands of communities in Central America, Africa, and Asia improve their livelihoods by restoring degraded lands to sustainable productivity. The program is also active in the U.S., educating students and communities about global issues, the environment, and energy efficiency. This partnership is a great example of how business and environmental interests can overlap and create value for the broader global community.
