Stylish, practical, sustainable - that is the FILL ME bottle. But there is much more behind the drinking bottle. It was not developed because the world needs another drinking bottle. It is part of a comprehensive concept and the result of various sustainable projects. It started with considerations about sustainability and drinking water supply, which Andreas Batliner, developer of the FILL ME bottle, has made. How do you bring about a change in thinking in the Swiss population: away from bottled water in disposable PET bottles and towards sustainable drinking behaviour? And how do you simultaneously help those who are less fortunate and have no access to clean drinking water.
