Begin with purchases and stockrooms
A recycling audit sees materials only after they become waste. Add purchasing records, supplier packaging, stored inventory, duplicate orders, and abandoned department cabinets. Choose a representative period and separate routine operations from office moves or events.
Measure the item and its pathway
Count or weigh categories consistently, then record whether each item is consumed, reused internally, returned, donated, recycled through a verified stream, treated as hazardous material, or discarded. A “recyclable” label is not an outcome if the local system does not accept the item.
Prevent demand before changing materials
Set shared stock levels, repair or refill where practical, standardize compatible supplies, and require a reason for urgent one-off purchases. Digital workflows can reduce paper only when they do not create unnecessary devices, subscriptions, storage, or accessibility barriers. Reusable products need a real return and cleaning process.
Report boundaries and exceptions
Publish the audit period, locations, categories, measurement method, missing data, contamination, and destination evidence. Avoid claiming zero waste when the calculation excludes construction, food service, electronics, or contractor-managed streams. Set a small number of actions with owners and a date for remeasurement.
Credible reduction starts upstream
Follow materials from request to verified destination, prevent unnecessary purchasing, and publish what the audit excluded. A smaller honest claim is stronger than a perfect-looking percentage.
