Keep paper and cardboard dry and free of food contamination. Remove non-paper items such as plastic folders, metal fasteners, and binder rings where possible. Flatten cardboard boxes to reduce volume. Place shredded paper in bags or boxes to prevent dispersal. Mixed or unsorted paper is accepted but pre-sorted materials attract better cash rebate rates and avoid sorting surcharges.
