Waste processing and disposal is all about using space and time efficiently. The less space waste occupies, the more you can haul in one load or hold in your landfill. The less time it takes to process waste, the more efficient your operation.
Whether you need to process tires, construction and demolition (C&D) debris, glass, plastic or paper, a shredder can be a cost-effective way to reduce material volume and increase profitability.
This is especially true now that shredders are used for wider applications and in harsher environments.
"Over the past decade we have watched shredders migrate from isolated pieces of equipment processing distinctive applications to machinery integrated into larger systems that convert material from one form to another," says Chris Nichols, senior engineer at SSI Shredding Systems Inc., Wilsonville, Ore. "For example, today, shredders help transform industrial waste into fuel, which feeds cement kilns and incinerators, in an effort to gain more constant burning temperatures for maximum processing with low air emission levels."
Recently, Waste Age surveyed shredder manufacturers to find a sampling of products that are available.
