Bin Lining

I try to minimise my plastic usage by not taking plastic bags at the supermarket. For some people, this raises the question - if I don't take plastic bags, what do I use to line my bin? Supermarket plastic bags are nice - and for some people, essential - bin liners, though if you look carefully consumer packaging uses plenty of plastic that can easily can be used to serve the same purpose, i.e. line a bin or hold trash. Think the plastic bags used for bread, food, clothes, etc. Perfect.
