Circular Innovation Lab
Machine-translated · View original
The lab explores a society in which materials and energy circulate, with natural capital at its center.

AboutAbout the lab
Toward a society where materials and energy circulate.
The Circular Innovation Lab aims to build a sustainable society through decarbonization and a circular economy, both approached with natural capital at the center.
Companies, government, universities, citizens, financial institutions, and students work together to develop technologies and social systems in which materials and energy circulate.
The lab works on developing technologies for use in society, running demonstration tests, and conducting feasibility studies.
It is an endowed research field established in April 2025 in the Environmental Engineering Division of the Faculty of Engineering, funded by a donation from a company.
Key terms
- Natural capital
- The idea of treating the benefits that nature provides, such as forests, soil, water, and living things, as capital (assets)
- Circular economy
- An economic system built on using resources over and over instead of throwing them away
- Endowed research field
- A research field set up at a university for a fixed period, funded by donations from companies or foundations

The lab aims to build a sustainable society through decarbonization and a circular economy, both approached with natural capital at the center. Its research areas are evaluating the use of recycled resources, recovering energy from waste and unused materials, managing circulating carbon, nitrogen, and phosphorus resources, using underground resources, and assessing the value of final disposal sites (landfills).
