By-products Beneficial Reuse

As the cost of all products and services increase, there is a greater need for more efficient waste management and conservation of landfill space.  Proper waste management results in an economic benefit, reduced environmental impact, and potential enhancement of environmental quality.

Our by-products beneficial reuse program is mostly aimed at:

  • Characterizing industrial and agricultural by-products

  • Determining and testing options for beneficial uses of the by-products

  • Determining and exploring the most safe and economical methods of disposal of the by-products

 
In addition to making recommendations for safe disposal, we have found several beneficial reuse options for different by-products, such as uses in landscape water filters, soil amendments, and components of synthetic soils.
 
 
 
 

 Some of the by-products that we have worked with include:

  • Drilling mud from oil and gas exploration
  • Directional horizontal drilling waste from urban and suburban utilities installation
  • Fly-ash from power production
  • Coffee hulls (aka coffee cherry)
  • Flu gas desulfurization (FGD) gypsum from power production
  • Drinking water treatment residuals
  • Acid mine drainage residuals from reclamation of acid mine drainage
  • Foundry sand (green sand) from the metal casting industry
  • Steel slag from the steel production industry
  • Expanded shale (Haydite)
  • Pipe scale from metal pipe production
  • Paper mill pulp from paper production
  • Leonardite from coal mining and power production
  • Various wastes from food processing
  • Swine effluent
  • Dairy manure
  • Poultry litter
  • Beef feedlot manure
