Show HN: Toothbrushes Made from Bamboo
- tlb 7y ago> every year 2 billion plastic toothbrushes end up in the oceans? Really? I dunno how many toothbrushes the world uses, but I'll guess 2 per person per year, so 16B/yr. So 1 in 8 used toothbrushes end up in the ocean? How does that happen? I would have expected 99.9% to make it to landfills.
- attendos 7y agoThere are 7.6 billion people on the planet. Each of us will use 300 toothbrushes during our lifetime (4 toothbrushes per year). A conventional toothbrush weighs approximately 18 grams. Each of us will throw away about 12 pounds of plastic toothbrushes in our lifetime. Plastic toothbrush waste generated during our lifetime = 80 billion pounds! I read about the 2 billion a year in an article that I can't find at the moment. I will do some more research about this and remove the quote for now. Thanks for your calculation and for pointing this out!
