Total Biogas

2,000 m³

≈ 40 backyard pools

Methane (CH₄)

1,200 m³

≈ 24 backyard pools

Electricity Potential4,200 kWh
CO₂ Offset1.76 tons
How to Use This Calculator
  1. Select feedstock type: 1 = animal manure, 2 = food waste, 3 = crop residue.
  2. Enter feedstock weight in tons and the volatile solids percentage (organic fraction available for digestion).
  3. Review Total Biogas (m³), Methane (CH₄) (m³), Electricity Potential (kWh), and CO₂ Offset (tons).
  4. Use the bar chart to visualize biogas vs. methane vs. electricity output for your feedstock.

What each input means

Feedstock Type
1 = Animal manure, 2 = Food waste, 3 = Crop residue
Feedstock (tons)
Weight of feedstock in short tons
Volatile Solids (%)
Percentage of total solids that are volatile (organic) and available for digestion

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Feedstock Type = 1, Feedstock (tons) = 10, Volatile Solids (%) = 80 = 3 input(s) provided
  2. Calculate Total Biogas
    Total Biogas
    2000 = 2000
  3. Calculate Methane
    Methane
    1200 = 1200
  4. Calculate Electricity Potential
    Electricity Potential
    4200 = 4200
