spheres at their disposal: resources of the geosphere (natural resources), resources of
the technosphere (atoms do not get lost) and the human ingenuity. Therefore, the
driver proposed for finding solutions in a market economy is the price. Technology
and human demand decide what of mineral resources are needed with what properties
and to what amount. We also have to acknowledge that an increase of prices induces
an increase of reserves. Thus the concept of scarcity is relative and may have to be
adjusted also from a mid- and long-term perspective. Via the feedback control cycle of
mineral supply in times of shortages and price peaks, there are incentives on the supply
side to produce more functions from primary and secondary materials, and on the
demand side to use less or to substitute materials, Fig. 1 [10]. More production, less
consumption will re-establish a market equilibrium. This feedback control cycle also
regulates the finding of the optimum in LCM. LCA helps to find better solutions while
the market optimum will be determined by price incentives.
5 Collective Action to Settled New Circular Economy
Business Models
A recent report from AFEP (2017) pinpointed that Multi Actor Action is a lever to
set up new circular economy activities. Stéphane Morel (Renault) proposal is to
discuss this statement and the potential for the life cycle community to contribute.
