Larger public agencies such as state governments and other large institutions like colleges, universities and correctional facilities often wield considerable purchasing power and can typically include packaging requirements in their bid specifications. This positions them well to benefit from Reusables, especially if they receive recurring large shipments of goods from the same vendors. For example, bid specifications can require the use of reusable pallets and totes for food deliveries, reusable drums for liquids such as cleaning agents used by public works departments or reusable hand-held containers for office supplies. Vendors typically pick up the empty packaging on their next delivery visit.
