Total feedstock mass
30 kg
Formula and working
C:N = (mass_brown × C:N_brown + mass_green × C:N_green) ÷ (mass_brown + mass_green)
- 1
Collect the inputs
Brown material mass = 20 kg; Brown material C:N = 60; Green material mass = 10 kg; Green material C:N = 15
- 2
Apply the formula
C:N = (mass_brown × C:N_brown + mass_green × C:N_green) ÷ (mass_brown + mass_green)
- 3
Result
Blended C:N ratio = 45 :1
