SSI Shredding Systems



SSI Shredding Systems, Inc. was formed in January 1980 in Wilsonville, Oregon when the idea of mobile shredders was new. The company’s initial product offering was a self-contained mobile shredder used to provide contract shredding services to industrial and government organizations. Use of this service was instrumental in developing the military’s widespread use of mobile shredding.


Flexibility was key in SSI’s early development. Our customers frequently came to us with unique problems, which compelled us to concentrate on engineering new solutions rather than off-the-shelf technology. The old idea that there was one solution for all, just wouldn’t work in this market. Our customers needed a choice of options.


As the processing needs of SSI’s customers grew, the demand for shear shredders expanded from temporary use to a need for dedicated systems. To address customers’ changing requirements, SSI began engineering and manufacturing a full line of rotary shear shredding systems.  The manufacturing experience as well as the operations and service expertise gained in the mobile shredding business positioned SSI to effectively meet customer needs and develop new market opportunities.
