The Zerocup calculator shows how much CO2, long-term costs and waste you can save by using Zerocup instead of single-use cups. Adjust factors based on your own operational setup, such as the amount of cups, reuse cycles, washing method and your current single-use cup costs. The calculator then provides clear estimates of CO2, long-term cost and waste savings, helping you understand what bio-based reuse could mean for your organization.
