Electric toothbrushes may first sound like a better and "more sustainable" alternative to buying and replacing cheaper disposable toothbrushes. But popular electric toothbrushes like the Philips Sonicare have a greater impact on our environment, considering the life cycle of packaging and parts that go into building and completing one single Philips Sonicare electric toothbrush.
What can we change to create an electric toothbrush that's more efficient from its' manufacturing point to end-of-life phase?
