Dunkin Donuts has been around for some time now and while we have seen them diminish in numbers of outlets, there are some that are still up and about. There is one outlet that has been put up in St. Petersburg, Florida, and it has been touted o be eco-friendly. In what way? Worms.
No they are not using the worms as part of their classic donuts. Rather, they are stored in a solar-powered composter.
All food and beverage waste is converted to fertilizer by a worm-filled, solar-powered composter behind the donut shop.
The worms eat the scraps and the resulting fertilizer is then provided to local farmers.
