why do you want to avoid plastic? (genuine question) I'm currently filling my new freezer and wish I had more plastic containers because they can be used year on year, as opposed to freezer bags that I can only use once and are a waste. Do you know something I should know about plastic?
I wouldn't put glass in the freezer. Not sure about ceramic.
but there's mounting evidence that plastic containers are a bit dodgy because they're not static, they age and leak.
I never worried about any of this stuff until I started working for an environmental organisation a few months ago and actually read what is out there, now I'm trying to green our family up a bit, but it's a gradual process...
