FEECO – Manure Granulation

About the Company:

FEECO is recognized globally as a leading provider of process development services, engineering capabilities, custom equipment manufacturing, and parts & service support for a range of processing operations, including bulk solids agitation agglomeration (wet granulation), mixing and conditioning, drying and cooling, high-temperature thermal processing, and material handling.


With this diverse set of offerings and an extensive background in processing bulk solids, FEECO serves nearly every industry, from fertilizer and agriculture, to mining and minerals, as well as chemical processing, paper products, and more. The company is also widely recognized for their ability to facilitate beneficial reuse applications and the recovery of valuable components from wastes and process byproducts.

About the Solution:

The pressure to solve the environmental and economic challenges manure poses to farmers and society is continually mounting, as nutrient losses, ground and surface water contamination, and nutrient inefficiencies continue to plague the industry.

The transformation of manure into a granular fertilizer product offers a solution to these problems, reducing the potential for nutrient runoff, helping farmers to realize the full value of their inputs, and creating a closed-loop nutrient cycle.

FEECO manure granulation systems transform recovered nutrient cake into a premium fertilizer product that exceeds the EPA’s pathogen destruction requirements for a Class A Biosolid. The resulting product is dry, storable, easy to handle and apply, and boasts minimal odor and dust generation.

While the manure granulation process can vary based on manure source and specific production goals, a typical setup involves a pugmill mixer followed by a rotary dryer with screening, air pollution control, and a recycle loop.

This setup is highly customizable and allows for the incorporation of additives to enhance performance or nutrient value. These systems are an excellent fit for operations looking to produce 5 to 10 TPH of product.

Manure-based fertilizer and soil amendment products are backed by batch- and pilot-scale testing capabilities in the FEECO Innovation Center, where experts gather process data and confirm proof of concept, proof of process, and more.

The technologies mentioned here are proven and backed by FEECO’s international reputation in providing the best in fertilizer production equipment and complete process systems. Nearly every major player in the fertilizer industry trusts FEECO for their equipment and process design needs.

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
