Sodapop sustainability

More than 7 billion tonnes of plastic waste end up in our oceans every year. Since the inception of Sodapop, we have been committed to responsible stewardship of nature. For instance, just one CO2 carbonation refill can save up to 40 large (1.5 litre) PET bottles from becoming waste. Sodapop now also supports the global movement "4Ocean". This movement is dedicated to the sustainable cleaning of the oceans, including through the sale of bracelets made from recycled plastic, the proceeds of which fund further cleaning efforts.

waterdrop: the most refreshing change for your water. Fruit meets water – iced tea without sugar.

Now new at Austrian Post branches: waterdrop - small microdrinks that refine your water with natural fruit and plant extracts. Simply add a waterdrop to your drink and enjoy! Whether you crave a refreshing, invigorating, or relaxing taste – our range of flavours offers the perfect aroma for every moment. waterdrop is sugar-free, vegan, and without artificial additives.
