Granutech-Saturn Systems Corporation

US based manufacturer of balers, crushers, shredders and granulators.

The original MAC (Mobile Auto Crushers) Corporation was privately owned and was formed in 1971 to manufacture auto flattening units and high-density balers to serve the scrap metal recycling industry. The "Big MAC" Mobile Auto Flattener is the most widely used piece of equipment of its type in the world.

MAC Corporation purchased Saturn Manufacturing (Wilsonville, Oregon) in 1980. Saturn Manufacturing began operations in 1972, manufacturing slow-speed rotary-shear shredders for a wide variety of size/volume reduction applications. In 1981, the fabrication of Saturn Shredders was incorporated into the existing manufacturing facility of the MAC Corporation in Texas; thus, the trade name of MAC/Saturn Shredders.

In 1994, MAC Corporation purchased Granutech Environmental Systems because of its special equipment technology and expertise in the rubber processing and recycling industry. This resulted in the expansion of our product line to include tire granulation equipment. With the acquisition of Granutech we embarked on an upgrade of the exiting tire granulation system that included the development of the Grizzly, improvements to the automated system controls, and improved fiber and metal separation systems.

The Roto-Grind, originally licensed from our UK partners, represented the most significant development in plastics recycling in more than a decade. The rugged single rotor shredder has excelled in the most difficult shredding and sizing applications and has been an immediate success around the globe. While the machine is unequalled for plastics recycling, the machine is routinely applied in fuel processing operations, aluminum recycling plants, and document destruction applications.

In January 1999 MAC Corporation (MAC/Saturn) was incorporated with Granutech-Saturn and the name was changed to Granutech-Saturn Systems Corporation of America.
