• linear human systems reky on non renewable reosurces + use resources before they are discarded 
• the circular economy use renewable resources + reuses materials whenever possible 

difference between the take, make + waste linear economy approach + the circular economy approach

the principles of CE: 

cycling of material 

energy derived from renewable reosurces 

human activities should support ecosystem 

diverse systems are more resistant to change 

connected systems 

desing of products for extented use 

design of products for end of life reuse 

seperation of technical + biological materials 

optimum production rather than maximun production 

tehcnologies to design new products + improve system effectiveness 

application of CE to sustainable lifestyles 

water supply 

diverse renewable systems 

food production 

energy supplies 

pollution control 

waste managment 

mineral resource managment 

linear economy: human systems rely on non renewable reosurces + use resources once before they are discarded 

CE; by contrast to the linear economy the CE aims to achieve sustainablity in all aspects of lifestyles + consumption, it uses…
