Eighty collection bins, a year-long trial, and zero deposits: Ecosurety and UWE Bristol have launched 'Lendable', a reusable cup scheme that strips out every step conventionally used to guarantee cup return — and will test whether friction-free reuse can scale beyond a single campus.

The scheme, which also counts SUEZ, Re-uz UK and Hubbub as partners, operates across UWE Bristol's Frenchay Campus. Hot and cold drinks bought from participating outlets — including Costa Coffee, Subway and the Students' Union Bar — come in purple reusable cups. Users return them to any of the 80 dedicated purple bins positioned across campus. No deposit, no app, no registration.

The design question behind the trial is blunt: does removing the financial and digital barriers that most reuse schemes rely on actually drive participation higher, or does it simply lose the cups? Most existing reusable cup systems in the UK lean on deposits or app-based tracking to secure returns. Lendable discards both mechanisms entirely, betting that convenience alone can sustain return rates high enough to make the model viable at city scale.

Richard Marriott, Head of Reuse at Ecosurety, framed the approach as a deliberate inversion of how reuse has been marketed. "For too long, reuse has often been presented as the harder option. We wanted to flip that on its head and make reuse the easiest choice people can make," he said.

"No deposits, no apps and no friction. Just take your drink, enjoy it and return the cup to a purple bin when you're done."

"If we're going to scale reuse, it has to work seamlessly for both consumers and businesses, and that's exactly what we're testing with Lendable."

The logistics loop is closed and contracted. SUEZ, under its ongoing partnership with UWE Bristol, collects the returned cups from campus and delivers them to Re-uz UK, a specialist in reusable packaging systems, for professional washing and sanitisation. Once cleaned, the cups go back to UWE Bristol for redeployment. SUEZ also carries the data collection and insight-gathering function throughout the trial — the participation and return-rate numbers that will determine whether the deposit-free model has commercial legs.

The cup itself carries a material-efficiency claim: the reusable vessels use up to 50% less material than conventional reusable cups, cutting the resource input — and the number of reuse cycles needed to break even against single-use — per unit.

Participation incentives are financial but decoupled from deposits. Students and staff can win prizes of up to £250 per month, tied to cup return rates across campus rather than individual transactions. The prize mechanism nudges collective return behaviour without reintroducing the per-cup transaction costs the scheme is designed to eliminate.

For UWE Bristol, the campus functions as a live research environment. Jo Dainton, Head of Circular Economy at UWE Bristol, said: "Lendable gives us a unique opportunity to test and evaluate circular economy solutions in a real-world environment while creating valuable learning, research and skills-development opportunities for our students and staff."

"It demonstrates how universities can play a leading role in accelerating the transition to a more sustainable future."

The trial runs for one year. Its significance for the wider sector lies in what it tests against: the UK's patchwork of deposit-return and app-gated reuse schemes, which consistently report participation ceilings tied to friction at the point of sale and return. If a no-deposit, no-app model sustains high return rates across 80 bins and multiple food-service operators on a single campus, it provides a replicable template for city-wide deployment — the explicit ambition stated for the initiative.

If it does not, the result will sharpen the case that some form of financial or digital accountability — deposit, token, or tracked return — remains structurally necessary for reusable packaging systems, whatever the consumer-experience cost.

The milestone to watch is the end-of-trial dataset: SUEZ's return-rate and participation figures, expected after the year-long run concludes, will decide whether Lendable graduates from a campus pilot to a scalable municipal proposition.
