Drinking bottles are often made out of plastic. That creates a lot of waste and uses a lot of resources. And if they find themselves in the wrong place, they will stay in nature for a very long time.
By having drinking bottles made out of compostable Biodolomer® biomaterial you reduce both waste and CO2 emissions. While still having exactly the same function. And if they accidentally find themselves in nature, they will soon biodegrade, leaving no microplastics.
