Reuse: Coffee Grounds for smells and the garden
February 8, 2012 Written By: Ken Lets face it - we drink a lot of coffee. Those coffee grounds can be put to good use and great minds are working on it."In research to develop a novel, eco-friendly filter to remove toxic gases from the air, scientists at The City College of New York (CCNY) found that a material made from used coffee grounds can sop up hydrogen sulfide gas, the chemical that makes raw sewage stinky." Dr. Teresa Bandosz, CCNY professor of chemistry and chemical engineering has been testing and developing air filters using "activated carbon" to use in industrial applications. Current materials like wood, fruit pits and peat work but don't contain caffine (which contains nitrogen) which boosts not only you in the morning, but the ability to clean sulfer from the air. Read the article on Physorg.com (a blog for science, physics, teach, nano and news). The good profesor also uses the grounds in her garden (they make great compost) especially for plants that like acidic soil. (Naked Binder would have to agree with her - we've been doing this for years!)
