Circular Economy

� Circular economy is a global economic model that

decouples economic growth and development from

the consumption of finite resources

� “managing materials more intelligently”

� break away from the linear “take – make – dispose”

model

� ideal model = “closed-loop economy”

� Principles

� Design out waste

� Build resilience through diversity

� Work towards using energy from renewable sources

� Think in ‘systems’ (� Material Flow Management!)

� Think in cascades
