While most online dictionaries define the shredder as “a device used for shredding documents as a security measure to prevent identity theft,” shredders can be of many types based on the material being processed. There are shredders designed to support material reduction across a range of recycling applications, including plastic recycling, scrap metal, e-waste recycling, wood recycling, and tire-shredding or recycling. The shredding process produces raw material to be re-introduced into manufacturing.
