Total (annual)
259.9 kg
0.3 tonnes CO₂e
By stream
Total weight diverted: 313 lb (142 kg)
Planning note
Focus
Paper + containers
Enter annual pounds from waste audits or hauler diversion reports.
High paper
Tune paper factor
Adjust factors when using de-inked vs generic paper LCAs.
Leverage
Often large kg CO₂e per lb
Small mass can still drive noticeable avoided emissions.
Dense materials
Weight adds up fast
Factors differ for cullet vs furnace efficiency—edit when you have plant data.
Method
Run low / high factor cases
Duplicate scenarios in the form by adjusting factors to bracket uncertainty.
Next steps
Offsets & net-zero tools
Compare avoided tonnes to offset purchases or pathway models.
Sample annual recycling weights and default factors produce roughly:
Total avoided (annual)
259.9 kg CO₂e
Tonnes CO₂e
0.3 t
For each material stream, we convert pounds diverted per year to kilograms, then multiply by your kg CO₂e saved per kg recycled factor. Summing across streams gives total avoided CO₂e. This mirrors common spreadsheet approaches used when screening waste and recycling programs.
kg_material = lb × 0.45359237avoided_kg_CO2e_stream = kg_material × (kg CO₂e saved per kg recycled)total = Σ streamsFactors represent avoided emissions vs your chosen baseline (often virgin production and disposal), not the full life cycle of collection unless you embed those in the factor.
Recycling displaces energy-intensive virgin processes
Compare avoided tonnes to flight emissions or net-zero pathways.
