Walz Energy plans to custom-feed 1,680 cattle in each of six partially enclosed open feedlots. "We'll be the hotel, the inn-keeper, the caregiver," Haman said. All the manure will be captured under the cattle in 2-foot deep manure pits "that will be flushed at least twice a day," Haman said.The manure will be mixed with feed and food waste, which will get pumped directly into storage tanks before getting mixed into six,1.5-million-gallon anaerobic digesters."Anything that stinks makes gas," Haman said.Micro-organisms will break down the waste, and the methane will be pulled off, converted into natural gas, and pushed through existing underground pipes to end-users.What's left over — called digestate — will be stored in the operation's 39-million-gallon open lagoon. Each fall the liquid fertilizer will be applied to farmland.The project is getting no state or federal tax credits, grants or loans.
