Replenish is a system and set of products designed to make reusing and refilling containers economical for the manufacturers and convenient for the consumer


Why don’t people reuse and refill their washing product containers? More economical technologies are available to manufacturers, but the current infrastructure does not create a convenient refilling system for the consumer. The Replenish Pre-cycling system and products are a solution for making refilling easy and practical. Soap refill pearls purchased with the customer’s normal online supermarket shopping are dispensed directly into their permanent reusable containers by the supermarket delivery staff in the customers’ home. The pearls of concentrated detergents are contained a dissolvable film coating until the user dispenses or dilutes them as required, making packaging waste a thing of the past.

We are throwing away an ever-increasing amount of waste, of which a large proportion is packaging. Inspired by research at landfills, carbon-zero developments, eco-activist meetings, in normal consumers’ homes, and by the challenge of reducing this unsustainable waste of resources, a refillable system for soap products was developed which considered all of the product stakeholders: producers, distributors and consumers. Iterative prototypes of the technologies, designs and experiences led to the system of packageless concentrated soap pearls that were economical for the manufacturer and the online delivery infrastructure that was convenient for the consumers.
