Common approaches for conducting waste management audits include record examinations, facility walk-throughs, and waste sorting. The first approach involves reviewing waste hauling and disposal records, as well as contracts with recycling facilities. The second approach requires a team of internal auditors to observe waste-generating activities and conduct interviews with employees. The third approach entails physically collecting, sorting, and weighing a sample of the organization’s waste, which can consist of a day’s worth of waste or a collection from each department.
