Calculate composting mass recovery from incoming organic material, finished compost, and other credited outputs measured on a consistent basis. The calculator reports total recovery, finished-compost yield, and the mass difference that may reflect moisture loss, biological conversion, and rejects rather than treating every missing ton as disposal.
Recovery rate = (finished compost + other recovered outputs) ÷ incoming material × 100. Process loss = incoming − recovered outputs.
Wet-basis and dry-basis measurements should not be mixed. Composting naturally loses mass through water evaporation and carbon conversion, so recovery is not a standalone quality score.
Planning estimate only. Verify site-specific engineering, contracts, regulations, and measurement boundaries before making commitments.
From 1,500 incoming tons, 620 tons of compost and 45 tons of other outputs give a 44.33% mass recovery rate and 835 tons of process loss.
Use one consistent facility or program boundary for every input and document whether quantities are measured at collection, receipt, processing, or shipment.
Yes, when all period-based inputs use the same month. The displayed annual wording should then be interpreted as the period you entered.
Use a weighted average for routine reporting or run separate low, typical, and peak cases when density, moisture, composition, or throughput varies materially.
No. The calculation covers the named metric and entered assumptions; permitting, safety, downtime, access, inventory, and local design requirements may need separate review.
Scale accuracy, moisture, inventory timing, contamination, operating hours, and inconsistent system boundaries can all cause actual results to differ.
| Input | Role |
|---|---|
| Primary quantity | Defines the material or resource entering the calculation boundary. |
| Operating assumption | Converts the base quantity into the requested capacity, cost, flow, savings, or rate. |
| Result | Use as a planning estimate and compare it with observed records. |
