We have a Kimberley under bench/sink bin which we use for general waste (front bin) and recycled plastic (back bin).
While we use calico bags when shopping, we usually get the odd supermarket type plastic shopping bag which we use as a liner. The standard supermarket bags fit perfectly into the bin system we have. Occasionally the shopping bag will have a hole which means it is placed in recycled soft plastics before use and other bag sought.
As single use shopping bags have been/will be phased out in may states, it would be good if Choice did do a test on plastic bin liner bags say for small, medium and large kitchen bins. I expect the purchase of these will increase after bans are brought in.
I should also add that we generate about a bag of waste every month (we compost, work farm, recycle inc. soft plastics, and also bury bones where possible), and sometimes have to replace the bag not because it is full, but because it has an unfortunate odour coming from it.
