Worth thinking about. The scourers last much longer than plastic ones. I do put a kettle of boiling water through them from time to time.
Grow a loofah !
Seriously, an ordinary loofah makes three dishscrubbers. Can't get much more ecologically safer than the loofah. It works well too
I compost everything I can, and I recycle what rubbish we do create carefully, so that it goes into the right bins, etc.,
My compost bins are worm worked, slow and sure and the most beautiful soil at the end of it.
I try to avoid plastic when I can, but when I can't, I recycle properly, and hope it ends up being used again, or I use bits like the trays the mushrooms come in as seed trays in my greenhouse. Lidded pots such as the ones the humous comes in are washed out, dried and passed along to a neighbour who batch cooks and mashes her veggies for the fortnight and then freezes the portions. Big yoghurt tubs make good sized pots to start peas and sweetpeas which have long roots.
Son2's old polo shirts become four cloths for cleaning, and the rest of the cotton pieces go into a bag for recycling (charity shops make a fair bit of money from cotton waste).
A looooong time ago I did a thread on recycling a shrunken wool pullover, I'm still inclined to make something else from stuff if it's not fit to go the charity shop for someone else to use.
