green economy demands complexity!
• 7 materials • Manufacturing energy 42MJ (per 20M lumen-‐hours)
• Use energy 60W
• 30+ materials (17 materials in LED chip)
• Manufacturing energy 343 MJ (per 20M lumen-‐hours)
• Use energy 12.5W
(DOE 2012, DEFRA 2009)

how will you design to reduce & recirculate resources? will collec3on rates deliver viable streams? what processing technologies are emerging? what guides or tools inform/assist decision making? is a shid to service based business models realis3c?
complexity = ques3ons

the linear (sweep it under the rug) system is broken

why have you made it un-‐repairable? upgradable?

is obsolescence part of your business model?

problem: the things we procure aren't green enough; the greenest things buy into systems! poten3al: need for partnerships across value chain – (waste management to design) GPP needs to ask ques3ons which reverberate through value chain
