Problem Challenge

The construction industry must transition from a linear to circular economy to contribute positively to the world’s growing climate crisis.

In Denmark, this urgent climate crisis has been recognized – and perhaps most clearly illustrated – by the adoption of the Climate Act, which obliges Denmark to reduce its total CO2 emissions by 70% in 2030.

Our mission is to drive the circular transition with our designs

At mellow designs we develop products that have circularity at their core. Our vision is to utilize our skill sets to become an industrial driver behind the circular transition.

We focus on prolonging the material’s life- cycle, cherishing its value, and reducing its environmental impact through circular principles and a zero waste philosophy.

We involve our users early in the design process to ensure that we design with people for people, and generate tangible value for our end users. We focus our efforts on challenges that have a global impact potential and are scalable across several countries.


We have 5 core values which are the north-start of our creative process:

  1. Flexibility
  2. Scalability
  3. Disruption
  4. Circularity
  5. Global Impact
