5 Tips for recycling used coffee grounds

Other than making beautiful body scrubs and soaps (like porze), there are many great uses for used coffee grounds.  Here are 5:

In the garden

Pest repellent

Sprinkle used coffee grounds around your plants to protect them against destructive garden pests like ants, snails, and slugs.  


If you grow acid-loving plants (like azaleas, hydrangeas, rhododendrons, camellias, roses) used coffee is the fertiliser for you!  Mix your old grounds with dead grass clippings, brown leaves, or dry straw to neutralize some of the acidity, the spread them around your plants.  Used coffee grounds add nitrogen and potassium to the soil as well as a boost of magnesium which all plants need to stay healthy.

Note: Just remember that this fertilizer lacks phosphorus and calcium so it isn’t ideal for encouraging blooms and fruiting.  For this, you'll need to add lime or wood ash to the mix.


If you don’t have an immediate use for the coffee grounds, throw them on the compost heap , they consititute 'green' matter..  Just limit the amount of grounds that you add to your pile so that you don’t throw off the ratio of 'green' to 'brown' matter.

Around the house

To absorb Food Odours

Used coffee grounds can be used much like baking soda for absorbing food odors in the refrigerator and freezer.  Just place a small open container of grounds at the back of the fridge, then forget about it for a few days.  After you remove the old grounds from the refrigerator or freezer, you can throw them on the compost pile or use them for fertilizer.

As a Natural Abrasive

Sprinkle coffee grounds onto an old cleaning cloth and use them to scrub away stuck-on food from counters or dishes.  While used grounds are abrasive, they aren’t so harsh that they will damage the surfaces in your kitchen.  (Just make sure you don't accidentally scrub grounds into any cracks where they might leave behind stains.

Use porze coffee ground soap on stained, grubby or greasy hands to both scrub off the grease AND absorb any greasy, grubby odours.
