Circular Economy Savings Calculator

A circular economy keeps products and materials in use for as long as possible through reuse, repair, remanufacturing, and recycling. By reducing the need to extract raw materials and avoiding landfill disposal costs, businesses and communities can significantly cut operating expenses while reducing environmental impact.

The calculator estimates CO₂ savings based on industry-standard emission factors for each material type. It multiplies the total weight of diverted waste by the difference in lifecycle CO₂ between landfill disposal and circular management (recycling, reuse, or refurbishment). Factors are derived from life cycle analysis (LCA) studies aligned with ISO 14044 standards.

This is the total mass of material that is redirected away from landfill or incineration through your circular strategy. It represents the gap between your current recycling/reuse rate and your target rate, multiplied by the weight per unit and total units processed per year.

Manufacturing new products from virgin materials is extremely water-intensive. By recycling or reusing materials, the water-intensive extraction and processing stages are avoided. The tool applies per-kilogram water saving factors specific to each material type (e.g., paper saves significantly more water per kg than glass) to estimate annual water savings.

This is a relatable way to express CO₂ savings. The average passenger car emits approximately 4.6 tonnes of CO₂ per year. Dividing your total annual CO₂ avoided by 4.6 gives you the equivalent number of cars that would need to be removed from the road to achieve the same emissions reduction.

Yes. The calculator works for businesses managing product packaging, electronics, or industrial materials, as well as communities running residential recycling programs. Enter the number of units (packages, devices, or households), their average weight, and your current vs. target recycling rate to see tailored results.

The results are estimates based on average industry emission and resource intensity factors. Actual savings will vary depending on local energy mix, transportation distances, specific product designs, and market conditions for recycled materials. For precise figures, a full Life Cycle Assessment (LCA) is recommended.

Reuse and repair generally deliver higher environmental savings than recycling because they preserve the embodied energy and resources already in a product without needing reprocessing. Recycling recovers material value but still requires energy to reprocess. The 'Combined' strategy option in this calculator reflects the higher savings achievable when reuse and recycling are used together.
