Coffee grounds

[Dgl]

I am wondering if it's OK to add coffee grounds to my bin. I believe they are quite acidic. any advice welcome?

You can add coffee grounds into your HOTBIN, yes. They are best if they are added to the HOTBIN when they've dried out a little.

If you are adding a mixture of different waste types into your HOTBIN regularly, with a range of different pH levels, your resulting compost should be close to pH neutral.

Would it be ok for stale unused coffee grounds too?
