Cigarette butts are responsible for the most devastating litter problems – over 4.5 trillion cadmium, lead, and arsenic-filled butts are discarded yearly, and 1.7 billion pounds of them are flushed into our waterways. Normal filters take up to 15 years to break down naturally, and two or three ingested by a small animal such as a cat, squirrel, or rabbit is enough to kill them. This problem isn’t going away either, as there’s little to no way to keep people from simply flicking away their cigarette butts and walking away. Greenbutts hopes to promote their organic cotton hemp and wheat flour product with no chemicals – a “green butt”. Coming in early 2014. These filters biodegrade in a matter of weeks, and while not preventing litter, they will make the litter much safer for the planet.
