![]() Results in lower NOx emissions when compared to many US coals, particularly the high-sulfur coals.ĮPA supports the highest and best practical use of scrap tires in accordance with the waste management hierarchy, in order of preference: reduce, reuse, recycle, waste-to-energy, and disposal in an appropriate facility.The ash residues from TDF may contain a lower heavy metals content than some coals.Tires produce the same amount of energy as oil and 25% more energy than coal.There are several advantages to using tires as fuel: Besides size reduction, use of TDF may require additional physical processing, such as de-wiring. Generally, tires need to be reduced in size to fit in most combustion units. Scrap tires are typically used as a supplement to traditional fuels such as coal or wood. Tires can be used as fuel either in shredded form - known as tire-derived fuel (TDF) or whole, depending on the type of combustion device. In 2003, 130 million scrap tires were used as fuel (about 45% of all generated) up from 25.9 million (10.7% of all generated) in 1991. Using scrap tires is not recycling, but is considered a beneficial use it is better to recover the energy from a tire rather than landfill it. Scrap tires are used as fuel because of their high heating value. ![]() Visit Missouris Division of Environmental Quality for more information.īackground | Cement Industry | Pulp and Paper Industry | Electric Utilities | Industrial/Institutional Boilers | Dedicated Tire-To-Energy Facilities Background Have any standards been developed for the physical characteristics of TDF?īackground: Tire chips were used as a blended fuel at the Utilicorp United Power Plant in Sibley, MO.How is TDF regulated prior to processing?.What are the emission and performance standards for facilities that use TDF?.What is the extent of dioxin/furan emissions from cement kilns or other facilities that use TDF?.How do stack emissions vary from facilities that use TDF versus conventional fuels?.What are the benefits of using tires as fuel?.What are the trends of scrap tires used as fuel versus other market applications?.Why use tires as fuel when there are other ways to recycle scrap tires?.
