Eastman Chemical Company, headquartered n Kingsport, TN, is an international supplier of organc chemicals, fibers anci plastics with annual sales of approximately $46 biNion and approximately 5300 customers worldwide. Tennessee Eastman Division, also located in Kingsport, is the company’s largest manufacturing fadllity The nine hundred acre site contains manutacturing facilities as well as industrial landfills, a wastewater treatment plant, power generation facilities incineration facihties, facilities for miscellaneous utility requirements and support services tor administraban engineering research, sales, environmental, health and safety and security.

Tennessee Eastman Division was established in 1920 to produce methanol for use in Eastman Kodak Company’s photographic film base Today the division manufactures over 400 industrial intermediate chemicals, two basic fibers and three basic types of plastics.

Waste minimization and material reuse and recycling represent a basic manufacturing philosophy, and process improvement to reduce waste is a continuing objective. Tennessee Eastman operates extensive solvent and acid recovery operations resulting in the recycling of billions of pounds of solvents and acids each year. Eastman’s hierarchy of secondary materials management includes direct reuse through aggressive marketing, recycle/reuse, combustion and landfill as a last resort.


The wastes generated at Tennessee Eastman are primarily high BTU, organic matenals that can be etfectively managed through combustion. For disposal of these wastes, Tennessee Eastman operates three incineration units, a liquid chemical destructor and two rotary kilns. In addition, Tennessee Eastman comanages sorne high BTU wastes ancl biological wastewater treatment sludges in coal fired boilers used to produce steam and electricity for the facility.
The existing liquid chemical destructor consists of a horizontal fumace, heat recovery boiler, quench chamber, packed-bed scrubber, high-energy venturi with demister and two induced draft fans in series, The liquid destructor will accept only pumpable liquids, and has a thermal rating of 50 M Btu/hr,

The existing two rotary kilns are nearly identical units and consist of a rotary kiln furnace, heat recovery boiler, quench chamber, high-energy venturi scrubber with demister and an induced draft fan. The two rotary kiln units share a common waste storage and operations building, a common water recirculation and blowdown system, and a common stack. Pumpable liquids are fed through liquid nozzles/burners mounted at the front face of the kiln. Solid hazardous wastes in various size containers are also disposed in the kilns. Nonhazardous solids in ihe form of general plant trash and bose bulk solids are also fed to the kilns via vibrating shaker conveyors.

Wastes disposed at the three incineration facilities vary in BTU, ash, chborine and metals content. There are over 2000
active waste streams compiling the waste profibe. Additionally, approximately 300,000 solid waste containers and over 20 million pounds of general trash and other bose bulk solid waste are disposed nnjjl.
