I put drain screen and catch all of them. Of course I put them in the trash.... I always drink my coffee with French press so that is what I do always...
I throw mine in the garden. It's good for the plants. A few years ago I saw this cool invention. It was a silicon piece that sat at the bottom of a press. It had magnets on the top lip. When you pushed your plunger down it locked in the spent grounds. You then pull the plunger up and the "cup" comes with it. You then go to the bin and turn it inside out...grounds come out easily. This was a prototype that I saw at a convention...anyone know if he made a go of it?
