It would be a waste to throw away coffee grounds as they are!

Happy Ethical Action!

How to make the most of it
What do you do with coffee grounds after brewing coffee?
Many of you might be throwing them away. But when you are trying to live as eco-friendly a life as possible, you might be wondering whether you should throw them away as waste or not. So, instead of discarding them, here are some ‘positive and easy ways to utilise them’.

  • Putting in compost

  • If you are using Kiero or LFC compost, you can also compost coffee grounds. Put it in with vegetables, fruit peel and bran, stir it in and cover with sand and bran to allow bacteria to decompose it.

  • As a herbicide. 

  • Coffee grounds contain a substance that inhibits the growth of whole plants and therefore prevents the growth of weeds. The members of Kamakura Ethical Lab actually carry it out at their own homes. Because weeding can be done with a natural substance, there is no reason not to use it. However, in order to prevent the residence of fungus and insects, please make sure to spread it after drying.

  •  

  • As fertiliser or compost

  • As mentioned above, it has a property of inhibiting growth, but when fermented for several months, it can be used as a fertiliser. Members of the Kamakura Ethical Lab say that weeds, avocados and potatoes grow well after autofermentation. The fermentation of coffee grounds definitely improves the environment of the soil.

  • For deodorisers and deodorisers
    After roasting, the coffee beans have many small pores on the surface, the same porous structure as activated carbon in household deodorisers. By grinding the coffee, the surface area is expanded and the deodorising and deodorising effects are further improved. There are several ways to do this, but the easiest way is to warm the coffee in a microwave oven for a few minutes without wrapping it in plastic wrap. Stir the mixture during the process and dry it thoroughly and evenly. Place in a cotton bag and place in odour sensitive areas such as toilets, fridges, shoe boxes, car interiors, etc. The effect lasts for more than one month.

  • Use in cooking 
    Studies have shown that coffee grounds are surprisingly rich in nutrients such as calcium, phosphorus, potassium, magnesium and antioxidants, which can be added to baked goods to improve their nutritional value and extend their shelf life. The smell of coffee also has a relaxing and concentration-boosting effect.
