KeepCup is an Australian company that made the world's first barista-standard reusable coffee cup, aiming to shift people's habits from single-use to reuse. In 2009, siblings Abigail and Jamie Forsyth — who had run a Melbourne café (BlueBag) since 1998 — founded it. Seeing the huge volume of single-use cups used in their café (polyethylene-lined and unrecyclable), they designed a reusable cup that fits under an espresso machine's group head and doesn't disrupt normal café operations. The bet that good design and usability would drive behavior change paid off: KeepCup defined the reusable-cup product category itself and is now used in 65–75 countries. Users divert large numbers of single-use cups from landfill every day. A certified B Corp (a founding Australian B Corp, 2014), its products are made from recycled stainless steel, cork, and more, and are designed to be repaired with replacement parts for long use. It conducts life-cycle assessments (LCA) and donates to Sea Shepherd and the Bob Brown Foundation.

KeepCup: A cup that shifts behavior from single-use to reuse. The letter is B; certainty is medium. Unconfirmed concerns are placed under “Watching.” (As of 2026-Q2; estimate based on public information.)
Main narrative
One person’s story (N1)
+ before → after
KeepCup first sold in 2009, at an independent design market in Melbourne. People immediately received it as an “answer” to the single-use packaging and waste problem that had troubled them. Cafés and roasters — especially baristas who brew coffee every day — welcomed customers who brought a KeepCup, granting a “social license to reuse” that helped the habit spread. The company's research says 41% of users go out of their way to avoid single-use.

- As the world's first barista-standard reusable cup, KeepCup defined the reusable-cup category, is used in 65–75 countries, and helps users divert large numbers of single-use cups from landfill every day. A certified B Corp (a founding Australian B Corp, 2014), it uses repairable design and conducts LCAs. Founder Abigail Forsyth received an OAM (2024).P1 independent recognition (B Corp / OAM) / Wikipedia / B Corp
− effects (confirmed)
- No confirmed −.
- Net environmental benefit depends on sustained reuse (benefit fades with replacement or infrequent use)
- Expanding into food containers (Go Bowl) and water bottles, and support from single-use levies and a global plastics treaty.
A second look
The core + is cutting single-use cups and shifting behavior toward reuse, plus circular, repairable design (nature), backed by B Corp certification, the founder's OAM, and independent LCA summaries. But as independent LCA shows, a reusable cup only undercuts single-use after a certain number of uses (8–60 depending on material), so the real net benefit depends on whether it keeps being used. That a cup bought but not used loses much of its value is a structural caveat.

How to read this assessment
- Reachable upper bound (ceiling): a confirmed − sets the ceiling, and independently verified + decide the position within it. + do not cancel out −.
- The weight of evidence is not symmetric: only confirmed − are counted; the volume of disputes or allegations goes under “Watching.” + are counted from independent evidence, while an organization’s own PR is treated as “reference.”
- Size is not value: scale is not used in the assessment. Matters that stay within money or competition—investors, shareholders, sanctions, trade secrets—are also excluded.
- The letter (assessment) and certainty (how reliable the information is) are separate axes.
This is a translation; the Japanese version is authoritative. The assessments here are generated automatically by AI based on published criteria. The operator does not alter individual results. Because they are AI-generated they may contain errors, and they are opinion and commentary, not statements of fact. Where evidence is insufficient, the entry is marked “On hold.” Requests for correction are accepted via the form.
