The Leader in Tire-Derived Fuel (TDF) System Technology...

TMI Systems, the leader in TDF system technology, specializes in augmenting cement manufacturing facilities with automated systems to utilize tire-derived and other solid-waste fuels. TMI-built systems maximize the benefits from TDF and other solid-waste fuels by providing precise reliable control of fuel feed rates. Our systems are built tough to withstand the demanding environment of the cement industry. Daily use of our equipment saves thousands of dollars in fuel costs annually at cement manufacturing plants across North America and Europe.


Scrap tires and other select solid-wastes, when properly integrated and injected into the cement manufacturing process, typically result in savings of 15% to 30% over the cost of conventional fuels without disturbing a kiln's operational capabilities, product quality, or environmental compliance.

Unique Automation from Beginning to End...

TMI developed the first fully-automated TDF system in the United States. We have over ten years experience to solve unique problems associated with automated TDF handling.

Feeding from bulk storage, our automated tire separation process supplies individual tires to the injection equipment. The separation process design has undergone more than seven years of development. This design includes a rugged separator, three refinement conveyors, accumulation conveyor and tire inspection for size and excess metal content.

Tire injection equipment situated at either the raw materials feed or mid-kiln, accepts individual tires from the separation process. Tires are weighed for precise fuel control and fed into the kiln through either a proprietary airlock or a third party mid-kiln injection valve.

A recent TMI innovation for mid-kiln feed, stages tires from beneath the kiln, thereby reducing structural and installation costs and providing easy access for maintenance.

From tire storage, staging, weighing, and conveying to airlock injection valves, electrical controls and programming, TMI provides the most complete TDF system technology available.

Systems Without Limitations...

Let TMI add the flexibility of conveying multiple bulk waste materials. By considering all available waste fuels at the beginning of your project, appropriate provisions can be made for adding new fuels in the future or including them from the start. TMI engineers have designed feed systems for iron waste, shredded carpeting, baled refuse, packaging waste and even coconut husks!

Complete Turn-Key Solutions...

and Project

TMI provides a full service staff of engineers and managers to meet your project needs. And, with over twelve years of TDF system building, TMI has the experience and knowledge to solve difficult problems with unique solutions. Using the latest in computer-aided design software, we offer complete design packages tailored to your exact specifications.


TMI skilled craftsman pride themselves on each piece of equipment they make. Experience and talent are combined to form a team of quality-minded individuals. In addition to producing our own fabrications, TMI uses the vast manufacturing resources offered in the Dayton, Ohio area. The highest quality components are used throughout our systems in order to withstand harsh environments.


TMI offers buildings and canopies to protect personnel, equipment, and waste fuels from adverse weather conditions. Water, ice and snow, when accumulated in scrap tires, reduces the energy benefit of the fuel. These shelters make maintenance easier and safer to perform in bad weather, they protect your investment, and are reasonably priced.


TMI provides experienced supervision during the installation process. We typically use local contractors for the mechanical, electrical, and civil installation requirements. Using local labor reduces the cost of installation and often provides labor personnel already familiar with the plant operation and safety.


TMI engineers and project managers remain on site during the system start-up process. During this time, we train your personnel to operate and maintain the equipment and fine-tune the system for optimum efficiency.

Our satisfied customers and their consistent fuel cost savings, best advertise our commitment to quality equipment and professional services. We have provided systems to the following operations:

  • Apasco Cement - Apaxco, Mexico
  • Apasco - Veracruz, Mexico
  • Blue Circle Cement - Atlanta, Georgia
  • Blue Circle Cement - Northfleet, England
