The Numbers Behind Reuse — KeepCup's Impact Calculator and What It Measures

The choices made every day add up. The question is — by how much?

KeepCup partnered with Edge Environment, an independent sustainability consultancy, to develop a Life Cycle Analysis and Impact Calculator that answers that question with data rather than intention. Carbon savings. Waste reduction. Energy conservation. Measured, verified, and available to run on your own numbers.

How Many Uses Does It Take?

The LCA gives a clear answer to the question we get asked most: how many times do I need to use my KeepCup before it outperforms a disposable?

KeepCup Thermal: 66 uses.
KeepCup Original and Brew: 24 uses.

Use your KeepCup every weekday and you've cleared the breakeven point inside five weeks. Most KeepCups are still in daily use at over 1,000. The numbers compound with every refill.

B Corp Score: 121.8

KeepCup is one of the world's founding B Corps — legally bound to consider and report on impact across employees, customers, community, suppliers, and environment. The minimum passing score is 80. Our current B Impact Score is 121.8.

We've been named B Corp Best for the World in the Environment category four times — 2018, 2019, 2021, and 2022 — placing KeepCup in the top 5% of B Corps globally in our employee size group.

The 2026 renewal is underway under the most rigorous B Corp standards in the certification's history.

Reuse at Scale

Individual reuse adds up. Institutional reuse adds up faster. KeepCup works with businesses, universities, and events to drive reuse at the scale that moves the dial.

Major tech campuses, including LinkedIn Dublin, workplace-wide transition to reuse across the office.

Australian Open, media and broadcasting teams cutting disposable cup use across the tournament.

University reuse programs, hundreds of thousands of single-use cups prevented from entering landfill across partner campuses.

Major corporate workplaces, reuse rates moved from single-digit percentages to majority adoption among thousands of employees.

Built to Last, Designed to Fix

A reusable product that can't be repaired is just a slower disposable. KeepCup is modular — every lid, seal, and band is replaceable. When something wears, you replace the part, not the cup.

Replacement parts available for the full range >

Recycling initiatives cover plastics, glass, and stainless steel. Packaging is cardboard-first and reused in our supply chain before it's recycled.

Reducing the Footprint of the Business

Solar-powered offices since 2015 in our Melbourne HQ and 2018 in our London office. Rainwater harvesting across both hubs. Sea freight over air freight as standard. Local manufacturing and assembly to reduce transport miles.

The operational footprint is part of the same brief as the product footprint. Both are measured. Both are being reduced.
