How to Use This Calculator
  1. Select Project Type (new construction, renovation, or demolition) and enter the Building Footprint (sq ft) and Number of Stories.
  2. Choose Construction Type (wood frame, steel, concrete, masonry) to apply material-specific waste factors.
  3. Enter Demolition Component (%) if the project includes partial or full demolition.
  4. Review Total Waste Generated (tons) and Achievable Recycling Rate to set diversion targets.
  5. Check Roll-Off Containers and Truck Loads needed to plan logistics and schedule hauls.
  6. Compare Disposal Cost (landfill) versus Recycling Savings to make the financial case for a higher diversion program.
