Recycled Plastic Credit Issuance Calculator
Calculate plastic credits issued from verified recycled mass while applying contamination deductions and buffer holdbacks.
Programme support tool. Follow the credit registry’s issuance methodology and retain independent verification records.
Examples
- Eligible mass 1,200 t, factor 0.95 credits/t, contamination 6%, buffer 10% ⇒ Net mass 1,128.00 t, credits 964.44 units.
- Eligible mass 750 t, factor 1.20 credits/t, contamination 3%, buffer blank ⇒ Net mass 727.50 t, credits 873.00 units.
FAQ
How should I evidence the eligible mass?
Use weighbridge tickets, third-party audit statements, or digital MRV system exports that match the reporting period.
What if contamination varies by batch?
Compute weighted averages or run the calculator separately for each batch to preserve traceability.
Can I include future production forecasts?
Only include recycled mass that has passed verification. Future projections should be documented separately in project pro formas.
Additional Information
- Result unit: tonnes for net eligible mass and programme-specific credit units.
- Contamination discounts typically cover non-plastic fractions, moisture, or degraded polymer quality; confirm the deduction basis with auditors.
- Buffers hedge reversal or double-counting risk; adjust the default percentage to match programme rules.
