CITRIS Foundry startup Wonderfil aims to solve single-use plastic problem

It was at the height of the pandemic when then-UC Santa Cruz Baskin Engineering student Shiloh Sacks and her long-time friend Amelia Eichel decided to pursue an innovative, sustainable project.

Their project was Wonderfil—an affordable and convenient liquid and cream dispensing refill station with a mission to solve the single-use plastic problem by eliminating the demand.

With initial funding secured from the CITRIS Tech for Social Good program and the CITRIS Foundry as part of the fall 2021 cohort, as well as Eichel’s alma mater Lewis & Clark College, that idea soon transformed from a low-cost prototype that Sacks built in her Santa Cruz living room to a successful startup. Current Wonderfil stations allow customers to refill on household products, including shampoo, conditioner, and laundry detergent, at an affordable price. All that customers need to bring to a Wonderfil station is a reusable bottle.
