Picture of Composting K-Cups
One of the significant downsides to all one-cup coffee makers is the waste they generate.

Submitted by think|haus for the Instructables Sponsorship Program.

Most often, the response to this problem is "buy the reusable filter cups" -- and that'd be great except it really doesn't help the convenience aspect. 

To solve the problem, my daughter developed her own method for reducing the cups to their components and getting the grounds and filters into the compost bin instead of the garbage. 

Unfortunately, the plastic used in the cups isn't recyclable, but at least the compostable product is not going into the bin.

Note: K-cup is a trademark of the K-cup people. I like the product, don't like the waste. This is not meant as a hinderance to their business model.

Step 1: Open the kcup

Safety first -- be sure to use a knife that is sharp (dull knives cause injuries) and work in a well lit area.

Use a knife (or other sharp implement) to cut into the foil top of the cup. Through experimentation, it has been discovered that quartering the foil is the best way to open the cup.

Remove the foil - it is probably not recyclable either - paint and plastic and such.

The aluminum foil lids look to be recyclable, if my Google search is to be believed.

I compost mine as well. I just poke my finger through the hole the machine punchs. Then dump out grounds and recycle the rest.

Man, you drink a lot of coffee!

It's aways great when folk recycle, and as far as I know the lids are recyclable, since it takes less energy to burn off the paint than it does to mine & refine more aluminum from scratch.
