What type of data must a facility provide for establishing a waste baseline?

To establish a waste baseline, a facility must provide documentation of the volume and weight of materials over a 12-month period. This precise and comprehensive data is crucial as it allows for an accurate assessment of the facility's waste generation patterns, which is essential for evaluating waste management strategies and setting targets for waste reduction.

Having detailed documentation of waste volume and weight reflects the actual waste generated, rather than estimates or projections. It provides a factual basis that can be used to track changes over time, assess the effectiveness of waste reduction initiatives, and engage stakeholders in waste management practices. Understanding the specific amounts of waste produced enables facilities to identify trends, evaluate operational efficiencies, and develop tailored approaches for minimizing waste.

Other options, such as only relying on past estimates or listing waste haulers, do not provide the detailed and quantifiable data needed to establish an effective waste baseline. Additionally, a future waste reduction plan is important but cannot substitute for the historical data essential for calibration and assessment of waste handling practices.
