Material footprint
= ecological backpack
Invisible burden any product carries
Measuring resource useMaterial Footprint

Abiotic material resources+ biotic material resources + top soil erosion in agri-/silviculture
Holistic, though rough indicator
Sufficient, input-based indicator although not addressing individual environmental problems

Conclusions
13/10/2015
Where do circular and bioeconomy meet:
- Bioeconomy helps making heavy resource use lighter, e.g. in buildings
- Circular economy helps keeping biotic products and materials in use
Sustainable lifestyles foster both circular and bioeconomy:
- Smart nutrition releases land use to other purposes
- Resource-light housing facilitates sharing solutions
- Shared mobility requires less infrastructure
