Stage 1 – Shredding

The reduction of whole tires down to shreds or chips utilizing A CM Primary Shredder.

CM Shredders

Byproducts: Clean cut shreds or chips.





TDF – Tire Derived Fuel

Used as an alternative to fossil fuels. Used primarily in cement kilns, steel mills power plants and pulp and paper mills. Size range: 1″ to 4″  [25 mm to 100 mm].

Benefits: Burns hotter and cleaner than coal or petcoke.

TDA – Tire Derived Aggregate

Used as a light weight fill material for civil engineering projects such as: back fill, slope stabilization, embankments, drainage and sound abatement. Size range: 100mm to 400mm [4″ – 16″].

Benefits: Very durable, excellent drainage, reduces vibrations, insulates and lasts a long time.

CM Equipment Used for Stage 1

CM Primary Shredder – Used to make larger cuts or single pass
CM Chipping Shredder – Used for TDF to make smaller cuts
CM Chip Shredder – Used for TDF to make    smaller cuts
CM Disc Screen
Assorted conveyors

Primary Shredder

Used to make larger cuts

Secondary Chipping Shredder

Used to make clean cut TDF

Disc Screen

Used to size material


Shredder + Disc Screen = TDF or TDA

Stage 2 – Steel Liberation & Removal

Tire shreds from a CM Primary shredder are introduced to the CM Liberator which removes the steel wire from the rubber fraction. Further reduction of the shred into ground wire-free rubber feedstock is accomplished. Clean steel is separated for resale. Fiber is extracted using a dust collection/air system.

CM Shredders

By Products: Wire free crumb rubber – 44 mm to 16 mm [1.75” to .625”] Clean steel up to 98 % free of contaminants





Additional Revenue Stream


Rubber Mulch

Used for landscaping

 Benefits: Deters insects, drains well, water gets to the plants, long lasting, does not fade, blow away or disintegrate, reduces weed growth and reduces soil erosion.

Playground and Equestrian Footing

Used as a loose cover for playgrounds or horse arenas.

 Benefits: Softer cushion for falls, long lasting, does not blow away, deters insects, comes in many colors!

Wire Free TDF

Used for waste to energy, pyrolysis or gasification applications

 Benefits: Results in high grade carbon char and makes excellent feedstock for syngas and bio-diesel fuels.

CM Equipment Used for Stage 2

CM2R Liberator – for smaller operations
CM4R Liberator – for larger operations
Belt Magnet
Steel Reclaim System with drum magnet (recommended for best quality clean steel)

Stage 3 – Granulation

The Granulator can accept 25 mm [1“] wire-free crumb rubber and process it down to 4 mm rubber granulate. At this stage, screens are used to size the material and an air system is used to extract the fiber.

CM Shredders

Products: Crumb Rubber







Artificial Turf

Rubber crumb placed between the blades of synthetic grass. Used in soccer, baseball and football fields globally.

 Benefits: Softer for falls, lasts a long time, less maintenance than a grass field, drains quickly for a drier, cleaner playing surface.

Pour in Place Surfaces

Used for running tracks, rubber tiles, pour in place surfaces, landscaping, and mats.

Benefits: Excellent drainage, lasts a long time, can be colored, less maintenance, very durable, absorbs impacts from trips and falls.

Rubber Molded Products

Used for running tracks, rubber tiles, pour in place surfaces, landscaping, and rubber mats.

 Benefits: Excellent drainage, lasts a long time, can be colored, less maintenance, very durable, absorbs impacts from trips and falls.

Stage 4 – Milling & Screening

The Dual Drive Crackermill will accept 4-8 mm crumb rubber and further process it into fine powders ranging from 10 to 80 mesh. The final stage in tire recycling, this stage produces clean rubber powder.

CM Shredders

Products: Fine rubber powder

Rubberized Asphalt and Molded Rubber Products



Rubberized Asphalt

A unique blending of powdered tire rubber, aggregate and special binders make for exceptional roadway and other paving projects.
 Benefits: Exceptional drainage, resistant to freezing temperatures, quieter than traditional paving, less cracking over time, uses less thickness than traditional asphalt, safer for the driver.

Injection Molded Products

The rubber powder is mixed with a binding agent to mold into a wide variety of new products such as auto parts, shoe soles, exercise mats, and is also used in building construction for the reduction of vibration or sound absorption on both floors and flat roof projects.

 Benefits: Durable, lasts a long time, binds with a wide range of different polymers, used in many industries.
