There can't be many homes where "disposable" plastic food packaging gets disposed of automatically - I hope! It's too easy to think that recycling is enough - it's not. Stuff put in the recycling bin still takes energy to be recycled even though it is not bulking out landfill. Don't miss out the "reuse" part of "Reduce, Reuse, Recycle" - please.
Most people, I think, use (disposable) plastic containers with lids in the store cupboard and freezer. I think butter or margarine tubs are great for single portions of soup, for example. An old ice cream tub corrals my spice jars and another keeps the jams etc tidy in the fridge. Craft supplies are neatly hoarded in hummus pots which are transparent and so I can see at a glance what's in each.
Old milk cartons often get cut in half, the top section making a handy scoop (with handle) if the cap is screwed back in or it will make a funnel if there is no cap on it. The bottom half gets used to keep pencils neat and I roll my tights putting one pair in each bottom half so they can stay reasonably neat in the drawer. Being square the pots sit together well.
Large circular plastic dishes make great microwave covers. I rarely need to use clingfilm as these are much easier to use. Smaller dishes are great plant pots and also get used for growing seeds which can then get potted on into yoghurt or cream pots.
Anybody got more ideas as to how more plastics can be reused?
