- 11 states have bottle bills (MI included)
- producing 1 kg PET requires 206 g Natural Gas for ethylene, 588 g crude oil for xylene, Liquid oxygen, and water
- 1kg diverted from land fill saves 1kg disposal +.78kg primary production
- buy back centers/source separated processors:.044MJ primary energy per 1kg PET
- curbside collection:.65-.8 MJ primary energy per 1kg PET
- materials recovery center:.38 MJ primary energy per 1kg PET
- each additional kg recycled reduced primary energy 46.2-56.3 MJ
