DVO anaerobic digesters help dairy farms reduce emissions and generate renewable energy. With 15 new installations in 10 states, DVO technology aids in sustainable waste management, boosting revenues and environmental stewardship.

As the American dairy industry continues to take steps toward a sustainable future, DVO anaerobic digester technology is playing an increasingly important role for biogas developers.

“Communities understand that modern digesters help make farmers even better environmental stewards of the land,” says Steve Dvorak, president and founder of DVO, Inc.

“This means biogas developers, dairies, and the communities they serve are increasingly eager to find new ways to manage their organic waste for the production of biogas and other valuable renewable products.”

15 new installations in 10 states

More than 15 new installations of DVO Two-Stage Linear VortexTM digesters were initiated or completed in 10 different states during 2023. Annually, they will have the combined capacity to produce 2.6 million MMBtus of renewable natural gas (RNG).

New DVO anaerobic digesters are now ready to come online at seven dairies in five states. Construction has also begun on DVO digester projects at eight additional dairy farms located across the country (see table below).

Reducing emissions, boosting revenues

Anaerobic digester technology from DVO allows dairy farmers to reduce their operations’ greenhouse gas emissions by capturing methane and converting it into renewable energy in the form of electricity, compressed natural gas (RNG), or diesel fuel substitutes.

DVO digesters outperform older designs by more than 30 percent, meaning farmers earn more revenue per cow. They also help farmers convert manure into clean, high-quality cattle bedding or soil amendment. In the process, pathogens and odors are destroyed, as well as weed seeds, resulting in reduced herbicide usage.

“Modern anaerobic digesters enable crop nutrients to be more economically condensed and transported to where they’re needed most, preserving vital waterways. These nutrients can now be spread on growing crops, reducing runoff potential, and increasing crop yield,” says Dvorak.

Climate-smart organic waste management

Having designed nearly 200 digesters since 2001, DVO can provide guidance and recommendations about climate-smart organic waste management solutions to dairy farmers and surrounding communities.

“The team at DVO is proud to support the US dairy industry’s efforts to reduce the climate impacts of food production,” says Dvorak.

“We all want cleaner air and cleaner water. And we all want food to feed an increasing population. Anaerobic digestion is a critical tool, and it’s one solution at our disposal today that makes a real difference. It’s exciting that more dairy farmers see the benefits of investing in DVO’s technology.”
