• Scalable

    Anaerobic Digesters

    From smaller operations
    to the world's largest industrial
    & agricultural facilities.

  • Scalable

    Greatly Reducing Climate Emissions

    Dairy biogas-to-RNG project economics favor the digester that reliably produces the MOST biogas "per cow." Currently DVO processes manure from over 375,000 milking.

  • Scalable

    High Performance

    Dairy example: Nearly 3 TIMES
    the biogas output "per cow"
    than covered lagoon digesters.
    See AD type comparisons, HERE.

  • Soil-Preservation

    Soil Preservation

    Practice “regenerative agriculture” by killing weed seeds without chemistry and maintaining a healthy & vibrant soil subculture.

  • Commercial-Industrial

    Industrial Wastes

    Including food & food production wastes / Urban organics from MSW / High-strength and mixed-wastes processing...

  • Poultry

    Hog, Poultry
    & Dairy Farms

    Maximize nutrient management, odor and pathogen destruction (including e-coli and salmonella), & total GHG reductions.

  • Phosphorus & Nitrogen Recovery

    Nutrient Recovery

    Economically remove & reuse up to 90% of macronutrients N and P, as well as essential micronutrients, from organic wastes

  • BioCNG

    Biogas to RNG

    Offset emissions when
    used as a transportation fuel.

North America’s largest biogas company puts renewables to work. For example: Our patented "Two-Stage Linear VortexTM" digesters process more farm and industrial wastes globally than any other company, or design.

Largely due to unparalleled performance: DVO's anaerobic digester (AD) systems greatly reduce odors, are cost-effective, scalable, operate automatically and require low maintenance. For given feedstock(s), no other digester design comes close to its biogas/renewable energy output and greenhouse gas (GHG) emissions reductions. DVO's is also the ONLY digester that enjoys "Recognized" status by the independent agency Newtrient, LLC.
. . . Crucially, most are still operating today (including the first in 2001). DVO is the U.S. market leader (also operating on all continents save Antarctica) for AD and environmental engineering, providing reliable, proven solutions and services to industry and agriculture for over 30 years.
