 Used coffee grounds are particularly noted as a soil amendment.Gardeners have reported the use of used coffee grounds as a slug and snail repellent, 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, and community sponsored initiatives exist, such as "Ground to Ground"  or the 'Green Coffee Shop Scheme' in Cambridgeshire, UK.
