This project is a part of the course Hållbar Utveckling at Chalmers University of Technology. The task was to redesign a coffee maker with sustainability in focus.

The reference object

The object analysed was a low price coffeemaker in the Philips Daily Collection constructed to brew approximately 7 cups of coffee. The coffeemaker was constructed with a built in 30 minute timer for convenient usage.


The reference object was evaluated with metods like the TNS framework and Eco Cost analysis to pin down the problem areas, power consumption and filter usage.

Eco Cost for the reference product. Product use (användning) stands out as the product phase with the biggest Eco Cost.


With power consumption and filter usage as the main problem areas we designed a new coffeemaker as a part of a new product concept with sustainable development in focus, re:PHILIPS. This concept focuses on the areas innovation, circularity, social responsibility and information.

The coffeemaker

To minimize the negative environmental effects of the product we chose to exchange the timer function and the coffee filters for a construction more like the existing Moka brewer.   By putting the coffee jug inside the water tank the newly brewed coffee is isolated and the coffee is kept warm without any extra energy usage. And by putting the coffee in a reusable metal container you won’t need any coffee filters.

The results

By implementing the new design with a isolated coffee jug and the Moka brewing system we accomplished a stunning 83% decrease in Eco Cost!
