Why Recycle?Why Recycle?Psychological – “feel good”
Environmental benefits – no land filling
Save finite natural resources
Engineering benefits
Lower greenhouse gas emissions (less trucking)
It makes cents…. (and $$)!
Impediments to ImplementationImpediments to ImplementationMisconceptions
Bad (past) experiences
Lack of knowledge
Regulatory challenges
Department (Agency)/Contractor willingness
