We now collect our used coffee grounds and work it into the soil. Worms love it, they multiply and grow fat. Worms are very healthy for the soil.
I even empty the k-cups into the grounds collection container before throwing out the cups. I hope a day comes when they will make the cups environmentally friendly so I can recycle those too. Until then, I've included a few links with ideas to repurpose k cups!
Below are several links to give you some ideas on what to do with your used coffee grounds. Maybe you will find a use that works for you.
