Re: [greenyes] Single Stream - Reply to Follow on Questions
Terri

Interesting point.

Actually you can standardize containers without violating anti-trust rules,
however industry opposes it beause they do not want designs dictated  If
there were less glass and the plastics was a bit standardized, then we'd use
less energy, less resources, and improve recyclability of the plastics
stream.  But this is the real world.

another point: beverage containers are a tiny part of the waste stream by
WEIGHT

However, has anyone ever studied what percentage of what people put at the
curb is beverage containers?]

And, has anyone looked at beverage containers by volume??

Just a thought outside the box.

Cheers
Michele
