Coffee grounds, tea bags and leaves go in the green bin

Coffee grounds contain a good amount of the essential nutrient nitrogen as well as some potassium and phosphorus, plus other micronutrients. The quantity and proportions of these nutrients varies, but coffee grounds can be used as a slow-release fertilizer.

Coffee grounds are high in potassium and nitrogen. The high carbon content helps feed the soil. Coffee grounds on their own are too acidic to be used straight on the garden but, once mixed with other organic matter such as manures or organic garden waste, they can make a fantastic compost mix for use in the garden.

Tea leaves are also full of nutrients and tannins that help plants grow. Loose leaf tea and paper tea bags are great for composting. However, some tea bags have plastic in them. This is usually evident by the glossy sheen and slippery feel. Plastic tea bags cause contamination issues so should be kept out of the green bin. 

Always remove any staples or label from your tea bags before placing them in the green bin.

As organic matter, both tea leaves and coffee grinds improve the soils drainage and aeration.

Which Bin? 

Coffee grounds, tea bags and loose tea leaves can go in the green bin, or your home compost bin. It’s best to remove the tea bag label and any staples, before placing in your green bin or your compost.
