Cadence Environmental Energy of Michigan City, Indiana has entered into an agreement with Lafarge with respect to the mutual use of patents relating to suspension burner technology.
 
Suspension burner technology is a unique and efficient method of reducing energy costs in precalciner cement kilns by using whole scrap tires as a substitute for fossil fuel. The technology functions by burning whole tires while they are suspended above the transition shelf inside the kiln. Up to 20% substitution rates are achievable with this energy-saving technology.
 
Both Cadence and Lafarge have patents relating to this suspension burner technology and, under the terms of the agreement, Lafarge can use the technology on their US kilns and Cadence can market and sell the technology to other companies in the cement industry.
 
Conserving fossil fuels and lowering energy costs are of vital interest to cement producers everywhere. Because of their huge energy appetite and sophisticated emission controls, cement kilns are perfect technologies for recycling a wide variety of waste into valuable energy.  Waste-to-energy recycling achieves the dual benefit of keeping waste out of the environment while conserving fossil fuels.
 
The suspension burner is an important technology link providing modern precalciner kilns with a new option for lowering fuel costs by using whole scrap tires. With the addition of Cadence Mixing Air, whole scrap tires can also be added through the feed shelf. These advanced technologies open new and significant energy saving options for precalciner kilns.
