Get the most out of your expensive coffee by saving the used grounds to use as mulch or to build an eco-friendly garbage compost. Use the grounds to add nutrients to the soil as well as naturally repel garden pests such as slugs and snails. You can also hang a handmade sachet featuring dried used grounds in a closet to absorb odors. Get creative by looking for other ways to put used coffee grounds to work around your home. If you have a lot of used grounds, store them properly until they're needed.
Place the used coffee grounds in an air-tight plastic or metal container, such as an empty coffee can or small plastic storage bin.
Store the used grounds in a refrigerator. Avoid storing the grounds at room temperature as they may get moldy.
Freeze the used coffee grounds in the air-tight metal or plastic container if you have a lot and don't plan on using them right away.
