I use the old filters when potting plants. I put them in the bottom of the pot to prevent dirt from falling out. I use the old coffee grounds around plants.

Guess I am a wasteful person, but with the coffee I make, there is a lot of oil floating on top from the grounds. I put in a melitta, then put the gold filter in and put the coffee in there. This helps catch a lot more of the oil. I am on a septic, which you aren't supposed to put the grounds down. I still get a tiny amount down , as it is impossible to get them all out before washing unless you would let it dry first and then brush before. I hadn't known you could compost the brown melitta. Now I will. I did compost my grounds for years, along with my peelings.

Why would you not compost it? It is a waste to use water to clean them. And paper that has come in contact with food should be composted. If you don't have a place to compost and the there is no place that accepts it. Check with public gardens that might be in the path of your job. Partner with schools to start a local garden and a place for composting.

I use a percolator type of coffee maker for my espresso...no filter needed
