Can Coffee Grounds Go Down The Sink?

While many of us love coffee, we don’t always love the grounds that are left after brewing.

We aren’t always sure what to do with the leftovers, and some of us may feel badly about tossing them into the trash.

Others may wonder whether or not coffee grounds can go down the sink.

Let’s look into this matter and find out!

Not Everyone Wants To Throw Coffee Grounds Away

Can Coffee Grounds Go Down The Sink

What many may not know is that there are actually a number of things you can do with coffee grounds aside from throwing them away or sending them down the drain.

It’s worth taking a look at your other options to see how you can get those grounds to keep working for you!

At the very least, you can get more use out of them before throwing them away!

What Can You Do With Coffee Grounds?

You have plenty of options when it comes to coffee grounds that you may not have realized before.

They are actually quite useful, in a variety of ways!

The following options are just the tip of the iceberg!

Keep Them In The Fridge

Coffee grounds can do a great job of keeping food odors at bay.

Consequently, you can easily keep an open container of them in the fridge and they’ll work to absorb the odors.

This is much like keeping a box of baking soda in your fridge, but you’re recycling your used grounds! It’s also important to use an open container, not an airtight coffee container like you would use on your counter.

It’s an easy way to get a little more use out of them after brewing.

Also, related and important, if you were wondering “can you could freeze coffee beans” for the same purpose it’s not something widely recommended.

Give Them To Plants

Coffee grounds can work in two ways for plants.

You can either add them to the compost pile for a garden or other outdoor plants, or you can simply add the used grounds to the soil of indoor plants.

Not only will grounds help to keep away unwanted pest bugs, but also have a lot of nutrients to offer!

This is a fantastic method for keeping plants healthy and avoiding the waste of throwing away coffee grounds.

Clean Your Hair!

Often, the products we use for styling our hair can leave a buildup of residue.

Because of this, it can be a good idea to get that residue cleaned out from time to time.

Believe it or not, coffee grounds can be a great way to do this.

All you have to do is take about a handful of the grounds and run them through your hair, making sure to allow them to exfoliate the scalp a bit.

Then, rinse them out well, the same as you would with shampoo.


Coffee grounds can also be used to exfoliate your skin.

By mixing a small amount of the grounds with some milk, cocoa powder and honey, you can get a great facial treatment at a low cost.

It’s a fantastic way to re-use your grounds and help yourself to get clearer, healthier skin.

For those who are big on skin care, it’s worth trying out!

What About The Sink?

If you’re planning on re-using your grounds, or spent k-cup grounds then it might be worth checking out how organic coffee beans might compare to standard varieties.

If your Keurig won’t brew and you clean your needle out in the sink the grounds can do damage on your pipes.

Options that are organic and high-quality like Fair Trade and Rainforest Alliance are not only safer on the environment, but may be a little better for your body.

When it comes to the sink, most plumbing companies recommend that you avoid sending grounds down the sink regardless if it’s from spent drip coffee from a drip machine, french press, or especially dried grounds.

This is because they are one of the products that can clog drains rather easily.

Do k cups expire and make it worse on your plumbing, not really any different than the fresh stuff.

Because of that, it’s a good idea to either throw out the used grounds, or use them for one of the purposes above.

That way, you won’t have to worry about clogs, and the grounds might still get some good use before they are gone completely!
