FEECO Waste Transformation

Whether you have a material you’re currently landfilling, or a process by-product that goes to waste because it’s not usable in its current form, FEECO can develop a process around your intended goal to transform your material into a value-added product. We utilize our unique testing facility, The Innovation Center, to test your material at both batch and pilot scale in order to determine the feasibility of the intended process and simulate commercial process conditions. We then use the data gathered during testing to scale up the process and engineer the equipment needed to carry out the process.


Our process experts can apply a variety of methodologies to upgrade your waste material or process by-product. This can include agglomeration, granulation, drying, and high temperature thermal processing, or a combination of these techniques. Our process experts frequently develop processes to:


  • Create a marketable product from a waste or process by-product
  • Upgrade the value of a material through refinement
  • Recover valuable materials from valueless carriers
  • Increase the value of a material through improved characteristics


Some transformations include turning sludges into organic-based fertilizers, clays and saw dust into cat litter, fuel pellets from petroleum coke dust, and recovering valuable metal from spent batteries.


“What the world today calls waste — to FEECO International, they are really just raw materials for products that haven’t been invented yet.” – Dan Madigan (President)

When FEECO converts a customer’s waste into a usable, profitable product, we are also helping that customer prevent wastes from ending up in landfills, creating a win-win situation for both the customer and the environment.
