Used coffee grounds
Used coffee grounds are the waste product from brewing coffee.
In gardens, coffee grounds may be used for composting or as a mulch.[1] They are especially appreciated by worms and acid-loving plants such as blueberries.[2] Gardeners have reported the use of used coffee grounds as a slug and snail repellent,[1][3] but this has not yet been scientifically tested. Some commercial coffee shops run initiatives to prevent the grounds from going to waste, including Starbucks' "Grounds for your Garden" project,[4] and community sponsored initiatives exist, such as "Ground to Ground".[5]
Used coffee grounds have other homemade uses in wood staining, air fresheners, and body soap scrubs.[1] They may also be used industrially in biogas production or to treat wastewater.[6]
