What does it take to make refill a habit?

Developed in collaboration with EcoWorks and supported by the Good Design Research initiative by DesignSingapore Council, this project explores how design can encourage long-term refill behaviours in everyday life.

While refill systems have the potential to reduce packaging waste, adoption remains a challenge. Many consumers still find it easier to purchase new products than to change existing habits.

This project goes beyond designing a refill bottle.

It explores how design can encourage long-term refill behaviours by understanding the barriers, motivations, and everyday realities that shape consumer choices.

Through multiple rounds of user testing and co-creation sessions with residents across Singapore, conducted in partnership with Residents' Networks and supported by MP Ms Poh Li San and MP Mr Foo Cexiang, we gathered insights into both the functional and emotional factors that influence refill adoption.

Grounded in user feedback, behavioural observations, and product trend research, the project seeks to create a refill experience that is intuitive, desirable, and trusted—making sustainable habits easier to adopt and sustain in everyday life.​

One recurring challenge was refill confidence. Users shared concerns about spills, bottle alignment, and the effort required to accurately position bottles beneath the nozzle.

In response, we designed an integrated funnel that makes the bottle's refill purpose immediately recognisable while providing greater confidence during refilling. 

To further reduce the need for precise manual aiming, the bottle and machine were designed as a complementary system, featuring matching alignment cues that help guide bottle positioning naturally.

Together, these interventions reduce cognitive effort during refilling, creating a more intuitive and trustworthy experience for both first-time and returning users.
