[GreenYes] Re: Mouth Smaller at Neck - Why?

I think I remember reading once that it has something to do with sorting
equipment like you suggested although to my knowledge that is incorrect.

The bottles are blow molded and the butter tubs and other non bottle plastic
are injection molded. Because they melt at a different temperature than
each other...That is why most always the programs will only accept #1 and 2
bottles/jars (narrow necks) but not tubs, trays, etc.

Subject: [GreenYes] Mouth Smaller at Neck - Why?


A lot of plastics recycling programs specify that they only collect 1 &
2 plastics that are "smaller at the neck than at the base" otherwise
referred to as "narrow-neck" bottles. However, I have not yet found a
reasoning for such a thing. If something is a 1 or 2 plastic, why does it
matter the size or shape of the item? I would guess it has something to do
with the machines they use to sort with.. but I don't know why else they
would say this. If 1 & 2 plastics are relatively easier to recycle than
others, and are having a higher demand, increased economic value, etc.. why
would they not wish to collect them all?
