How hard is it to understand general waste and recycling?

I don't have bins because my dog gets into them so I use the bags for life for recycling and smaller bin liners for general waste.

Every single time my mum comes to put rubbish away she will throw general into recycling and I have to keep telling her.

Now when I was a work we had 3 bins general recycling and food waste.
Yet some person would still get them mixed up.

We even had a presentation to make it clear!
