Local compost planning
Make a volume-reduction assumption visible without predicting a pile's actual decomposition or maturity.
Verify material safety, maturity, local rules, and intended use before acting.
The calculator reduces entered starting volume by the percentage you enter. It does not measure settling, moisture, material density, temperature, or decomposition.
A 200 L starting volume with 50% entered reduction displays 100 L finished volume in the model.
