MONTGOMERY COUNTY, Tenn. – Bi-County Solid Waste Management took possession of a new M&J shredder this week. The shredder has the capability of shredding demolition waste, Class I waste, (household wastes and commercial wastes), mattresses, and tires.
The machine can shred approximately 70 tons of waste per hour. On the first day of use, 151.16 tons of demolition waste and 200 mattresses were shredded.
Mattresses and tires are challenging items to process in the landfill. Mattresses hold water that can cause seeps or leakage of leachate which is liquid that has come in contact with garbage. Leachate seeps require special clean-up, which takes time and manpower away from other important landfill duties. Bi-County has been paying to send tires off-site for processing, as whole tires cannot go in the landfill.
Bi-County Operator Gerald Waynick stated “Even with all of the incoming demolition waste I accepted today, I could not keep the hopper full. The shredder worked great and gave us the time and room to process more waste.”
The cost of the industrial shredder was approximately $865,000. It is expected to provide an excellent return on the investment by providing better compaction in the Class III Demolition Landfill, adding to the longevity of the landfill cell, which allows for more waste in the cell, and offsetting the cost of cell construction. Shredding tires and mattresses on-site also saves time, manpower, and contractual tire processing expenses.
Director of Bi-County Solid Waste Mark Neblett stated “We surveyed a test area and will track the shred volume to make comparisons of the density/volume ratios. Sites in other states claim the shredding process has increased air space by 30-40%, allowing more waste in the same permitted area. We are excited to use this machine and ultimately add space and time to the landfill.”
