I love yellow, gelbe sack that is! Gelbe sack (translate to yellow sack/bag) trash is the best & most environmentally friendly there is. It gives recyclable items you never thought about a second life. Gelbe sack should account for almost 80% of all your everyday products. From shampoo bottles, plastic egg cartons, toothpaste, to milk carton & juice carton/bags. Think of it like this, most packaged food + products materials will most likely go into gelbe sack or either paper recycle.
