Gryphon – Drying System

Advanced Drying Technology

About the Company:

Gryphon Environmental’s Advanced Drying Technology dries residuals and biosolids waste streams so that the solid residuals may be used as fuel or renewable materials. The economic and environmental impacts are both very attractive for Gryphon clients. Landfill of sludge with high water content is eliminated and renewable fuels, fertilizer, or fabrication components are produced. The result is the elimination of an Operating Costs and the liability of landfill, as well as the reduction in fossil fuels being utilized to generate power.

About the Solution:

Gryphon Environmental, LLC provides advanced drying technology. By creating repeatable manufacturing processes that are wrapped around advanced automation and advanced thermodynamics, our technology is the first to provide breakthrough technology at a fraction of traditional CAPEX and OPEX costs. These enhancements are bundled with a re-circulating air stream design that reduces/eliminates the demands of air permitting. Gryphon works with industry to bring viable solutions from processing of biosolids to the formation of properly-sized dried particles that agriculture demands. Automated, efficient and sustainable, Gryphon is revolutionizing the drying industry.

Solution Strengths, Weaknesses and Critical Indicators

Active Drying Technologies:

  • Produce a marketable product, dry manure solids, and reduce transportation costs
  • Require energy to reduce water content and dry manure solids, purchased energy cost are an issue
  • Require operator attention in excess of other systems due to the risk of combustion
  • Other compounds are released with the water (i.e. ammonia, hydrogen sulfide), and require additional treatment
  • Potential loss of ammonia nitrogen due to volatilization
  • Proven technology for storage reduction, odor control, GHG reduction and pathogen reduction

Newtrient Comments/Opinions:

Evaporation and Drying Technologies:

  • Uses heat to produce either manure with less water or dried manure solids
  • Systems that reduce water in manure use a series of evaporators to sequentially evaporate water from liquid slurries—energy is supplied either by purchased fuel and/or waste heat from other processes
  • Systems that dry separated solids use either a belt or drum to evaporate water from separated solids—energy is supplied either by purchased fuel, electricity and/or waste heat from other processes
  • Chemicals are released with the water (i.e. ammonia, hydrogen sulfide), and this often requires additional treatment such as condensation of the water and/or scrubbing of the chemicals
  • The requirement for purchased energy and costs are a significant concern leading to a tradeoff between input costs and gains in liquid concentration and transportation/market of by-products
Newtrient will continue to work with Gryphon to further refine the cost and performance information as more information comes in with new commercial dairy installations.
