Cardboard milk bottle
Invented by Martin Myerscough, and manufactured by Greenbottle Ltd, these milk bottle concepts are made from recycled cardboard, with an inner sleeve of compostable plastic made from corn starch. They are produced on similar machines to those which make egg cartons. "The biodegradable bag acts a barrier for the milk, and when you are finished with the carton you tear the bag out and put it in the general rubbish. The cardboard can go in with paper collections, in with garden waste or ideally it can be home composted."† The cardboard bottles are made with 'size', a special material that makes the product waterproof for forty eight hours. The inner sleeve of the Greenbottles take six weeks to biodegrade in landfill.† The bottles retail at £1.20, the same price as the plastic alternative for the same brand of Marybell Milk.
During the one-week trial, customers at the Lowestoft branch of Asda are being asked to provide their comments to manufacturer Greenbottle.† Part way through the week they had already received 40 positive comments from consumers.
If successful other applications include packaging for smoothies and fruit shakes. However, if used for these products, the inner plastic film would have to be adapted, since it would not be suitable for containing the more acidic fruit products.†
Mr Myerscough said: "The plastic part could be composted, but it is a very thin bag. The cardboard could go in a paper or green waste collection and then people who donít recycle can put it all into the general waste as it will biodegrade."
