The digested fiber in Magic Dirt™ is a byproduct made exclusively from DVO, Inc.’s patented anaerobic digestion (AD) process.  Anaerobic digestion is a collection of processes by which naturally occurring microorganisms transform waste into valuable byproducts in a controlled, oxygen-free environment.


DVO’s patented Two-Stage Mixed Plug Flow™ anaerobic digester is unlike any other AD technology. Traditional anaerobic digestion technologies feature above-ground tanks, which are inefficient and costly to build and operate.

DVO’s modern design allows for a more complete digestion of waste streams, destroys more pathogens, produces more renewable energy and captures more valuable nutrients economically.  Organic waste is processed in the digester for approximately 20 days at a temperature of 100°F while being constantly agitated, which allows for better waste conversion to environmentally beneficial and useful renewable and recycled products.

Anaerobically Digested Fiber

Since 2001, DVO, Inc. has been solving manure and food waste management challenges, transforming organic waste streams into power and other useful byproducts at the highest levels of efficiency and reliability in the anaerobic digester industry.  Nearly 100 of DVO’s patented Two-Stage Mixed Plug Flow™ anaerobic digester systems are installed at more than 70 farms in 17 states, with total electrical generation capacity of more than 75 megawatts. DVO digesters are also running in several countries internationally. For more information, visit
