In this interactive design lab, TNO and Gispen share the framework they have developed on circular business and the tools they created. What are the design criteria on products that make circular business possible? TNO and Gispen present results of the project ‘Use it wisely’ for designers, producers and business. How do the tools work? What did TNO and Gispen learn? How can designers use these tools? Learning by doing, to show the performance of the tools, that’s the way to go in this design lab session.

8. Circular Economy – Product Design
Why?
- Design for what and which state
- Design choises (material, pollu>on, weight etc.)
- Dis>nguish between products
- Not one strategy but a more nuanced insight
- Design for future func>onali>es

9. Circular Economy – Product Design
What would you think would be the
biggest challenge when designing circular
products?

10. Circular Economy – Product Design
How to solve?
Develop methodology that:
- S>mulates con>nues innova>on and
development
- Combines various known and to be developed
solu>ons / requirements
- Is easy to use
- Is usable through >me (embedding new findings)

11. Circular Economy – Product Design
Are there any elements you would like to
add to this list of condi>ons?

12. Circular Economy – Framework

13. Circular Economy – Framework
Method
Each module has an ambi>ous goal
Modularity:
“Each product module has at least two
func8ons (func8onal change) during its en8re
lifespan / use of the module.”

14. Circular Economy – Framework
Method
Each goal has various checklist ques>ons
that are scored.

15. Circular Economy – Framework
Method
The scores and underlying calcula>on
then provide one score per product.

16. Circular Economy – Framework
First reac>on?

17. Circular Economy – Framework
How to develop and proceed?
- Itera>ve approach
- Check and prove with LCA calcula>ons
- Goals, checklist ques>ons and best
prac>ses for circular design – adding on
