  • 15. 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
