We must exclude certain materials that will harm our machines and/or are unfit for our responsible recycling/disposal methods. This is why we reserve the right to reject any material that’s not suitable for the shredding and recycling process. We have high standards for safety and proper materials management. Before arranging services with us, please take a look at the following list of unacceptable materials. We cannot accept three-ring binders, metal hanging folders, spiral-bound notebooks, metals, plastics, batteries, non-paper items such as trash, paper products with food on them, or wet/moldy materials.
