How to Use This Calculator
  1. Enter Daily Waste Input (tons/day) — the amount of municipal solid waste delivered to the facility for combustion.
  2. Input the waste composition percentages: Paper & Cardboard, Plastics, Food Waste, and Wood & Yard Waste.
  3. Set Overall Moisture Content (%) — higher moisture reduces heating value and power output significantly.
  4. Enter Plant Efficiency (%) based on the type of energy recovery system (typically 20-30% for mass-burn facilities).
  5. Review Power Output (MW) and Annual Electricity (MWh) to evaluate the facility's generation potential.
  6. Check Homes Powered and Net Heat Value to communicate the energy recovery impact to stakeholders and regulators.

What each input means

Daily Waste Input
Daily waste tonnage fed to the combustion facility.
Paper & Cardboard
Percentage of waste stream that is paper/cardboard.
Plastics
Percentage of plastics (high energy content).
Food Waste
Percentage of food waste (high moisture, low energy).
Wood & Yard Waste
Percentage of wood and yard waste.
Overall Moisture Content
Average moisture content of the waste stream. Food-heavy waste can be 40-60%.
Plant Efficiency
Thermal-to-electric conversion efficiency. Modern WTE plants: 22-28%.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Daily Waste Input = 1000, Paper & Cardboard = 25, Plastics = 15, Food Waste = 20 = 7 input(s) provided
  2. Calculate Power Output
    Power Output
    26.6 = 26.6
  3. Calculate Annual Electricity
    Annual Electricity
    210481 = 210481
  4. Calculate Homes Powered
    Homes Powered
    20046 = 20046
  5. Calculate Net Heat Value
    Net Heat Value
    4353 = 4353
