About Us

Stephen Dvorak, PE, designed DVO's patented digester in 1999, and built the first of this unique new design in 2001. DVO has since installed over 140 digesters at +130 sites in 24 states within the USA (more in other countries). About 10 additional are under construction.

Industrial and agricultural DVO digesters collectively produce over 80MW of renewable power. Many DVO dairy sites have already been successfully converted to create RNG for the California low-carbon fuel standard market.
