Waste Reduction Impact — Emissions Saved by Recycling vs. Landfill

What’s Being Compared?

• Baseline (landfill-only): All entered material sent to landfill (or your chosen incineration share for comparison).
• With recycling: Your recycled share takes a recycling process cost but earns a credit for avoided virgin production. The remainder follows your landfill/incineration split.
• Savings: Baseline CO₂e − With-recycling CO₂e, shown per material and in total.

Tips

• Aluminum and steel often yield large savings due to high virgin footprints.
• Food/organic waste can have higher landfill impacts because of methane; local composting/aerobic treatment differs.
• Update factors with your region’s data for better fidelity.

How This Waste Reduction Calculator Works (and How to Use It Well)

This tool estimates greenhouse gas (GHG) emissions saved when materials are recycled instead of going to landfill or incineration. It’s designed for planning and learning, not policing behavior. You can adjust every factor to reflect your context, then see the effect instantly. All calculations run locally in your browser; nothing is uploaded.

What the Factors Mean

• Recycle process (kg CO₂e/kg): Emissions from sorting, transporting, and reprocessing material.
• Virgin avoided (kg CO₂e/kg): The estimated footprint you avoid when recycled feedstock replaces new (virgin) production.
• Landfill (kg CO₂e/kg): Average emissions per kilogram if the material is landfilled.
• Incineration (kg CO₂e/kg): Average emissions per kilogram if the material is incinerated.

The calculator compares a simple baseline where 100% of material goes to landfill against your chosen mix of recycling and (optionally) incineration. Savings are: Baseline − With Recycling. Because “Virgin avoided” is a credit, recycling can be net-negative (i.e., a benefit) if the avoided virgin footprint is larger than the recycle process cost.

Inputs, Units, and Periods

Enter weights in kilograms or pounds and choose a period (per week or per month). The tool annualizes your entries based on the selected period and months per year. You can also show “savings per kg” alongside annual totals to compare materials on a like-for-like basis.

Interpreting Results

• Annual Impact bars: Quick view of total baseline vs. with-recycling emissions.
• Table: See each material’s annual weight, baseline, with-recycling emissions, and savings.
• Per-kg savings: Useful for prioritizing materials when budgets or time are limited.

Good Practices and Tips

• Edit factors: Replace placeholders with values from your local processor, municipality, or LCA source.
• Mind contamination: Real-world recycling rates depend on sorting quality and market demand.
• Consider organics: Food and yard waste often drive landfill methane; alternatives (e.g., composting) may differ.
• Prioritize high-impact materials: Metals commonly show high “virgin avoided” benefits; plastics vary widely by type.

Limits and Transparency

All numbers here are awareness-level estimates. Real impacts depend on local technologies, energy mix, capture rates, transport distances, and material quality. Use this as a directional tool and refresh the factors when better data is available.
