The "Manure Challenge" is a startup competition for innovative manure-management technologies and products. Organizers have received more than 60 applications for the contest. They will narrow their selection to about 10 companies in late August.

The Manure Challenge is organized by Yield Lab Institute with guidance from the World Wildlife Fund, Newtrient and the Dairy Farmers of America. The groups support investment in the manure-management sector. The competition also recently received the support of Cargill, The Maschhoffs and WeWork FoodLabs.

“Together we can deliver meaningful solutions that improve productivity and profitability while minimizing our environmental footprint,” said Heather Tansey, sustainability lead for Cargill’s global animal-nutrition and protein groups.

Aaron Ratner, managing director for Ultra Capital, said innovative financing mechanisms and technologies are bringing industrial-scale solutions to commercial livestock-manure management. Ultra Capital provides advisory support to the competition.

The competition will support selected companies in commercializing their products through mentorship, commercial-strategy guidance and network access during a six-month program. Upon conclusion of the programming phase, selected companies will compete in a pitch competition for a cash prize. Visit for more information.
