More than 14 million tons of chicken litter is produced each year in the United States. It’s a significant challenge in need of a solution. CleanBay Renewables believes our process to turn this waste into renewable natural gas and organic fertilizer is part of the answer.
Each of our plants can recycle more than
150 thousand tons of chicken litter annually,
through a process called anaerobic digestion.
Enclosed tractor trailers with specialized walking floors deliver chicken litter directly into our airtight systems, all within minutes of arriving onsite.
The chicken litter mixes with water in an oxygen-free digester tank at a temperature of 98 degrees Fahrenheit and remains there for roughly 25 days. During this process, the materials begin to break down creating two usable products – a renewable natural gas and an organic fertilizer.
This renewable natural gas is made of methane, the same material commonly used to heat homes and cook. The gas rises to the top of the tank while the solid materials, called digestate, sit just below.
The renewable natural gas is pulled from the tank and sent through a gas cleanup catalyst. It can then be collected and transferred to the local natural gas distribution system or sent to an onsite electricity generator.
The remaining solid material is further refined using mechanical and chemical processes to create an organic fertilizer product. This process helps significantly remove and stabilize elements like phosphorous and nitrogen, which in some regions easily wash away, polluting the water supply.
The organic fertilizer is then available for local farmers and their suppliers to use as a natural additive for their fields. It will provide the same micronutrient and soil bulking properties as other products, but without the oversupply of nutrients.
The water used in the process is then fully recycled into the plant.
