American Document Destruction Services
is the only company that
can guarantee complete destruction of your
sensitive materials.
Through a process
known as "witness
burn incineration," your sensitive materials are burned in a waste-
to-energy boiler for 45 minutes retention at
over 1800 o F.

This is the same process used by local government agencies to destroy confiscated contraband.

 The Destruction Process
At the Niagara Falls American Ref-Fuel Waste-to-Energy Facility
1. American Document Destruction trucks enter the site at a computer-controlled weigh station and are directed to an enclosed tipping hall.

2. Confidential Materials from the trucks are unloaded directly into the refuse bunker.

3. The overhead crane mixes the materials and transfers them from the bunker and drops it into the waste charging hopper.

4. The charging hopper holds a ready supply of materials for charging the grate system.

5. The ram feeder pushes the solid materials onto the uppermost roller of the Duesseldorf Roller Grate.

6. The constant rotation of the set of rollers tumbles and distributes the materials evenly along the downward slope of the roller grate to promote thorough combustion. The speed of the rollers, the quantity of combustion air provided and the speed of the ram feeder are individually controlled to maintain optimum furnace conditions.

7. The heat generated by burning the materials produces steam in the waterwall boiler.

8. The control room houses the computerized central monitoring and control network for the facility.

9. After combustion of the solid materials on the roller grate, the remaining ash falls off the final roller into the water-filled ash quench trough.

10. Approximately 10 percent of the energy produced by the turbine generator is used to operate the plant and the balance is sold to the energy customer.
