What happens when you put an industrial design student, big ambitions, and a spray can in one room? sepa:spray. 

With this project, Matthis develops spray cans that can do what others cannot. Canstructed for circularity, these cans are modular, refillable, and reusable across multiple lifecycles. Driven by his passion for sustainable product design, Matthis is determined to spark a real canvolution, redefining how spray cans are made, used, and reused. His goal: to eliminate excess waste, reduce production costs, and prove that circular design can be both practical and scalable. 

The problem sepa:spray is solving is the massive waste and inefficiency caused by conventional aerosol cans. Traditional spray cans are a single use, mixing propellant and product in one container, making them impossible to refill or recycle efficiently. sepa:spray changes with a modular system separating propellant and product into two recyclable aluminum units. The propellant canister can be reused multiple times with different product canisters and refilled at retail refill stations. A smart scanner checks each can’s condition and lifecycle, ensuring safety and quality. When a can reaches its limit, it’s returned and fully recycled via a deposit system. By replacing fossil-based propellants with air or CO₂, sepa:spray creates a truly circular, resource-efficient system, turning waste into a closed loop and making the aerosol industry fit for the future.
