OT: Plastic into oil

They still have glass milk bottles in my local shops. A milkman also goes down my street.

I think people like the plastic bottles, because the milk is much cheaper if you buy a big plastic bottle than a 1 pint glass bottle. Kind of the basis a supermarket works upon, making you buy bigger packets of stuff for cheaper prices.

much better idea: stop using so much plastic. use and re-use glass. remember glass milk bottles? wash and re-use.simple idea, far less waste.
