Summary: Rockwell International, Corp. has achieved a major energy breakthrough at its Marysville, Ohio plant. The company now uses combustible trash to fuel its heating and air conditioning system. The heart of the system is a Kelley Pyrolytic Furnace and Energy Recovery Unit. It converts waste into hot water which is used to heat the plant in cool weather or channelled through an absorption chiller for air conditioning in the summer. ​ Because this unique system is now providing major portions of its heating and air conditioning needs, this Rockwell plant is no longer solely dependent on outside energy sources. According to William Smith, Superintendent of Facilities, "With this installation, we could conceivably increase the size of the plant 50 percent and still live within our present gas allocation." Rockwell estimates that the system will carry a return on investment of 21.50 percent. The list of companies installing Kelley Energy Recovery Systems is impressive: John Deere Co. at its Horicon. Wisconsin plant uses trash-generated heat for a paint drying operation resulting in an annual savings of $52,000. Xerox Education Center in Columbus, Ohio converts paper waste into heating fuel, saving $38,000 annually. K.W. Muth in Sheboygan heated an entire 90,000 sq. ft. plant last winter with a Kelley System. To date over twenty-five major corporations have purchased Kelley energy recovery equipment. Each of these progressive companies is converting combustible trash into energy, not only to save substantial amounts of money each year, but also to reduce dependence on future supplies of natural gas and fuel oil.
