OP-T2-41: Chemical Reuse Inventory

Purchase smaller lots of materials on a more frequent basis. Purchase only volumes that can be utilized during a defined period of time (e.g. every 3 or 6 months). Utilize suppliers that can offer quick delivery of needed materials. Only purchase products/chemicals in bulk when it is known for certain that bulk volumes can be used expeditiously. Establish a centralized purchasing system within the department or area to monitor chemical purchase in an effort to avoid duplicate orders. Attempt to redistribute unused materials and chemicals to other campus users. Objectively evaluate the potential use of chemicals offered for redistribution by other campus users. Reclaim and reuse materials when feasible (e.g., utilizing spent solvent for initial gross cleaning step and utilizing fresh solvent only for the final rinse).(e.g. Having a naphtha- based parts washer serviced by a reputable service company that reclaims the spent degreaser).
