Use defaults or enter your facility factors for better accuracy.
Tip: choose a material to load typical factors.
Example data table
| Scenario | Material | Input (tonne) | Recycling rate | Yield | Transport (km) | Net CO₂ saved (kg) |
|---|---|---|---|---|---|---|
| Baseline | Aluminum | 2.5 | 65% | 92% | 180 | ≈ 13,100 |
| Short haul | Steel | 10 | 50% | 95% | 60 | ≈ 7,020 |
| High recovery | PET | 3 | 80% | 90% | 250 | ≈ 3,050 |
Values are illustrative; use your verified factors for reporting.
Formulas used
Input_kg = Quantity × Unit_to_kg
RecycledInput_kg = Input_kg × (RecyclingRate / 100)
UsableRecycled_kg = RecycledInput_kg × (ProcessYield / 100)
CO2Saved_kg = UsableRecycled_kg × CO2Factor
EnergySaved_kWh = UsableRecycled_kg × EnergyFactor
WaterSaved_L = UsableRecycled_kg × WaterFactor
LandfillAvoided_m3 = UsableRecycled_kg × LandfillFactor
TransportCO2_kg = (RecycledInput_kg/1000) × Transport_km × TruckFactor
NetCO2Saved_kg = CO2Saved_kg − TransportCO2_kg
Energy-based avoided CO₂ is shown separately to help avoid double counting when your CO₂ factor already includes energy effects.
How to use this calculator
- Select a material and confirm the unit and quantity.
- Enter your recycled feedstock share and expected process yield.
- Add delivery distance and your logistics emissions factor.
- Keep typical impact factors or replace with your verified LCA values.
- Submit to view results, then export CSV or PDF if needed.
FAQs
1) What does “net CO₂ saved” include?
It subtracts estimated transport emissions from the process CO₂ savings. This helps compare nearby versus distant recycled supply options.
2) Why are there editable impact factors?
Recycling benefits vary by technology, region, and supplier. Editable factors let you use audited lifecycle data instead of generic assumptions.
3) What is process yield in this context?
Yield represents the usable fraction of recycled input after scrap, contamination, trimming, and rejects. Lower yields reduce realized benefits.
4) Can I use this for mixed materials?
Yes. Run one calculation per material stream, export each result, then combine totals in a spreadsheet for a full plant view.
5) How should I set the truck emissions factor?
Use your carrier or ESG reporting factor if available. Otherwise, keep the default and document it as an assumption for transparency.
6) What does “energy-based avoided CO₂” mean?
It converts saved kWh into avoided CO₂ using your grid factor. Treat it as informational unless your CO₂ factor excludes energy impacts.
7) Are the default factors suitable for official reporting?
They are rough typical values meant for planning. For formal disclosures, replace them with your verified lifecycle inventory or supplier data.
8) How do I improve accuracy quickly?
Update three items first: verified CO₂ factor, realistic yield, and actual transport distance. Those usually drive most of the outcome.
