Cash for manure? Workshop looks at ways to clean up watershed


MARIA STEIN, Ohio — A March 8 workshop in western Ohio aims to clean up Grand Lake St. Marys — and in doing it, give farmers a new source of income.

“Turning Manure into Ca$h” features new technologies for turning livestock waste into sellable fuel, fertilizers and bioresins.

Five state organizations that work in agriculture and natural resources are behind the workshop.

“We have new manure rules in place for Grand Lake, but we still have the same amount of manure, so we need to look at ways of reducing our nutrient loads,” said Jim Hoorman, one of the speakers and an Ohio State University Extension educator in Mercer County.

“Farmers can adopt these technologies, sell their manure for a profit, and reduce their nutrients,” Hoorman said.

Algae booms

Grand Lake St. Marys has been hit hard the past two summers by toxic algae blooms, which caused boating, fishing and swimming closures and threaten the lake’s tourism industry.

Scientists link the blooms to nutrients in farm runoff, with nitrogen and phosphorus the main culprits.

The Ohio Department of Natural Resources, as a result, has put new rules in place limiting manure use near the lake.

“Many farmers are reaching limits on how much manure they can apply to their fields due to phosphorus limits on their fields,” Hoorman said. “So these alternatives give them a way to stay in business and get value-added products from their manure.”

Other options

One option is selling swine manure to produce bioresin, which Hoorman said can replace up to a quarter of what’s in asphalt. Paint and fertilizer coatings can be made from it, too.

With the demand for asphalt high and the price over $500 a ton, a farmer can make up to $10 per pig space by selling their manure to make bioresin, Hoorman said.

Other topics will include anaerobic digestion and methane production, removing phosphorus from dairy wastewater and from swine manure, the results of a bio-oil farm demonstration, and the water quality benefits of removing nitrogen and phosphorus.

The speakers will be from OSU Extension plus the Ohio Department of Agriculture, Louisiana State University, Shoup Farms, Innoventor Inc., Multiform Harvest Inc. and NuVention Solutions Inc. A question-and-answer session will follow the talks.
