This system turns cow manure into fertilizer before it can decompose into greenhouse gas

Dairy farms account for about 2% of total greenhouse gas emissions in the United States. Manure in waste lagoons decomposes into methane, a major greenhouse gas.

The Varcor system from Sedron Technologies recycles biosolids into carbon-negative ammonia and dry fertilizer. Varcor also processes dairy waste into certified organic liquid nitrogen and phosphorus-rich dry solids. Traditional nitrogen fertilizer production and wastewater treatment contribute significantly to global greenhouse gas emissions, but the Varcor system disrupts this cycle by capturing ammonia directly from wastewater, preventing unnecessary emissions and reducing reliance on petrochemical-based fertilizers. “It costs less than current methods,” says Stanley Janicki, Sedron’s chief commercial officer, “and it is solving incredibly large environmental issues.”
