It looks like one of the many solanum, reminds me of aubergine but not sure

Possibly Physalis, looks like a plant given to me earlier this year

If it was in your home made compost, it must be something you grew last year,  have a look back, it may come to you.

Not necessarily; if your food waste goes into the compost bin, it could be a seedling of anything you bought to eat which had seeds in.  I agree with those who've said it looks like the solanum family, though not potato or tomato.  So aubergine is a possibility, if you eat them.  Why not plant it in a pot and see what comes of it?

I agree it looks a lot like aubergine. I potted on a pumpkin plant from my compost this year. But then I read the cautionary poisonous courgette thread. As I had thrown both eating squashes and ornamental pumpkins onto the heap I both didn't want to risk myself misidentifying the type and the thought of my bees taking toxic pollen to everybody in the neighbourhood (only a prob if they gather seed for next year) meant I hurredly dispsed of it before the first bud opened. I had no idea!.

Could be physalis. Are the leaves soft and slightly sticky? I am still growing physalis from plants which popped up in the garden after using my home made compost. I think the temperature was never great enough to kill seeds in the compost.
