We needed somebody who knew even more about digesters. We ended up talking to Steve Dvorak. A lot of vultures descended on us, said they were engineers. They really didn’t have too much to offer when it came right down to specific questions. Steve had a lot of good ideas, a lot of answers, and experience. And so, after visiting with him a few times it was pretty obvious that we’d be able to work very well with him. So we went with DVO.

Gordon’s system has been very reliable. ‘A farmer should not invest in a digester solely to generate electricity,’ he says. He recommends that farmers do the same by investing in a system that ‘has an excellent track record.

The digester setup, which has been constructed at this site, has virtually eliminated all manure odors…. Taking into consideration the number of animals at this site [3,300], the aroma is better than one would expect from a 100-cow operation without a digester.
Town of Rantoul, Calumet County, Regarding Holsum Dairy, WI
The digester allows us to have another source of income. We also use this as a way to be better neighbors. The odor issues that the dairy used to experience have been minimized to the point of being negligible now. We’re very proud of it. It makes us better neighbors and that’s something that we set out to do for that reason.
Don Niles, Dairy Dreams, WI
When a business such as ours makes an investment of this size, the consensus from our family was to go with the proven technology. For us that meant DVO.
Matt Maxwell, Maxwell Farms, VT (dairy)
We’ve worked with DVO over the years and have always been very happy with the superior performance of their digesters and the dependability of their people. We’ve found that their digester design delivers more biogas than other options in the market.
Chad Hoerr, General Manager of BioTown BioGas LLC
Cenergy has found that the DVO digester technology is the most effective system for removing volatile solids and yielding long, linked fibers after solids separation. The fibers give Magic Dirt the porosity and water holding capacity that emulates peat moss.

I can’t imagine dairying without a digester. We feel it’s really good for our public relations, our environment. We would never do any dairying without a DVO digester. Even if the electricity and manure solids sales made it only break even, the other benefits the system brings to a dairy would still make the digester essential.
