How to Use This Calculator
- Enter Total Permitted Capacity (cubic yards) from the landfill's operating permit.
- Input Capacity Used to Date (cubic yards) to establish the remaining available airspace.
- Set Daily Waste Intake (tons/day) and Compaction Ratio to convert incoming tonnage to consumed airspace.
- Enter Diversion Rate (%) and Annual Intake Growth (%) to model the effect of recycling programs and population growth.
- Review Estimated Years Remaining and Estimated Closure Year to inform capital planning and permit renewals.
- Check Capacity Status to assess whether the facility is on track or needs immediate siting of a new cell or alternative disposal.
