107 40 Ideal waste sorting trashcan J. Hammerskov DTU Energy, Technical University of Denmark I NTRODUCTION In Denmark, we are very aware of the importance of recycling as much waste as possible. As it is now our renovation workers already collect paper separate from our household waste. There's just one big problem. We don't sort any other reusable materials in our household. We Danes have a disposal system for bottles and cans of soda, beer, water etc. It's called "Dansk Retursystem". It has the motto "It's all about responsibility". The idea is good, but in practice it's more incriminating to people to be obligated to deliver the "pant" (bottles and cans) back to the supermarket, rather than sort it themselves, and then have their own choice whether they want to bring it to the recycling center or they want the renovation workers to get it for them. This concept I'm introducing to you should with time be able to replace our current disposal system - and even be more environmentally sustainable. THE PRODUCT WHICH’S MARKING THIS CONCEPT GREAT Two different examples of "The Ideal Waste Sorting Trashcan", which everybody should have in their kitchen: Why is this concept environmentally sustainable First of all; transporting these empty bottles and cans in for example a plastic bag, destroys the plastic bag and makes it impossible to reuse. Otherwise these bags can be used for groceries transporting lots of times. Furthermore "Dansk Retursystem" emits a unnecessarily large amount of CO2, by the double transporting, necessary to get the recycling waste first from the consumer to the supermarket and then from the supermarket to the recycling center. By this concept, this transporting would be cut in half. That's a great beginning - remember; "It's all about responsibility". An even more important aspect to consider regarding this concept is; during ordinary cooking, a lot of the food comes in plastic packaging. Normally this plastic just goes to the household waste, which isn't the best solution, considering that it could be sorted and recycled. A similar issue is when you buy food, contained in metal cans, glass jars etc. this metal and glass usually just end up in the ordinary trashcan, from where they end up at the combustion. Nevertheless if you had this Ideal Waste Sorting Trashcan, the jars would immediately be thrown in the glass-garbage bag, and the cans in the metal-garbage bag - from where it could be recycled just like paper does (but separate).
