I cleaned out the big freezer yesterday and it is amazing what you find in that basket at the bottom I found three partial cans of assorted brands of ground coffee. We bought an espresso maker a few years ago and all these types were bought to use in it. That fad died down and the coffee was forgotten until now. I know that coffee grounds are okay to put in the compost bin but what about unbrewed ground coffee? I can't find any info about those. I have a total of about 2 and a half pounds and am pretty sure I shouldn't just dump the whole lot in there at once.
