Gryphon Converts Chicken Waste into Organic Fertilizer

Owensboro, KY

Gryphon Environmental ( released that a Model 1040 dryer is currently being installed in the SE United States. The dryer will convert up to 100 tons of wet chicken litter into pathogen-free, organic fertilizers on a daily basis. The Gryphon dryer was selected for its efficiency and automation. The advanced drying technology uses sensors to identify characteristics of the wet chicken litter and automatically adjusts the drying conditions to ensure that quality organic fertilizers are produced.

The technology is being utilized to solve a growing problem with waste streams from large chicken broiler and layer facilities. The high nutrient value of the chicken litter is of little value as a wet product. However, dried into the small particles that result from Gryphon’s drying process, the dense organic fertilizer can be transported to areas that benefit from the nutrients and can be applied with traditional spreading equipment. Along with reducing transportation costs, the storable material helps to boost agricultural production. The Gryphon system was selected based on its many benefits. The re-circulating air stream reduces or eliminates odor generation, while the mechanical design reduces capital costs and enables future expansion and rapid installation. The system is anticipated to be operational within three weeks of delivery. It will employ enhanced software that monitors drying conditions and yields. In addition, the software automates the majority of maintenance functions and reduces the amount of operator time associated with the process.

Tid Griffin, CEO of Gryphon, commented: “The growing challenges of waste generation are resulting in growing costs for businesses and municipalities. The movement of nutrients from regions with dense populations of livestock or humans into areas that can benefit from these nutrients is essential to sustainability. We are pleased that our advanced technology is a part of the solution, and that our affordable design has both a positive financial and environmental impact.”

Nutrient recovery has been a leading topic in both economical and environmental discussions worldwide. In the United States, EPA regulations on wastes streams and the demand for organically-produced foods have often been perceived as unrelated problems and opportunities. New technologies are now bridging that gap.
