Waste bin in a symbol

Hi all 
Just wondering if anyone has any ingenious suggestions for a waste bin In my 2013 symbol

Cheers 
Al

I would be interested in a solution but after 4 years I haven’t found one!

2 pictures, the first of which my girlfriend insists on putting up when we are away. The second picture is when I’m away on my own like now in the New Forest with just my bike for company

I'm thinking the second one's good, cheap too 

A self adhesive hook (command strips so it is easy removed) stuck somewhere with a carrier bag on it.

Thank you Dave 
That is a good idea 

Waste bin outside not good idea as accessible by wild life, would suggest you keep it in van. In which case in a plastic bag to keep in any smells. See if you can sell the idea from that angle.!!!!

Definitely not outside here in the New Forest with the horses/cattle roaming free.
Last year I watched a family (who obviously hadn’t camped here before) set up a lovely breakfast spread on their outside table. A couple of ponies soon took advantage including a whole loaf of bread!

I use this bin in the WXL, I have secured the frame to the plastic bin to make it more stable and I have the glovebox open which has a cup holder fitted and this just clips over the edge of the glove box

I just have a loose bin liner on the floor at the back of the van next to the fridge. I don’t use the back doors, so it’s not in the way.

Some great replys, thanks 
I've knocked up a cardboard one out of a couple of small boxes and reinforced it with parcel tape and wedged it down beside the loo

I have just bought 2 black mini dust bins soft water  proof material which folds up for storage small but reviews says adequate for in the cab.put in bin liners small ones and then just through away at the end of a journey, also handy on site.
