It's not that used plastic bags, wraps and film can't be recycled into new materials – they simply require a different collection system and processing equipment than many curbside recycling programs provide. So please don't put plastic bags/wraps/film in your bin if your recycling program says NO.
How clean does my recycling have to be?
Scrape all the solid food scraps out of jars and cans and then put them in the recycling bin. If you're concerned about having left over food in the bin you can lightly rinse out your jars and cans. Using left over washing up or rinsing water is best as there's no point wasting good water just to wash recycling.
Do you need to take labels off to recycle?
If you can remove labels and lids from glass jars and bottles, that's great, but don't worry too much because, in the recycling process, the items are re-washed. After crushing, any non-glass objects are removed. Removing the caps and lids from plastic containers is more important.
