Four years ago, Bethany Barbouti found a way to put her master’s in sustainable food systems to use by opening the Eco Flamingo, calling it the city’s first “zero-waste” general store. No plastic bags here: Shoppers bring in their own containers to help themselves to bulk-bin items ranging from coffee and spices to laundry detergents and shampoos. Elsewhere in the sunny shop, you’ll find unique kitchen goods like reusable food pouches and bamboo-and-sisal dish scrubbers and organic bath and body products like limoncello soap and lavender Earl Grey Lip Butter. The latest twist: At the new Sustainability Center two doors north, the store hosts the Eco Farm Stand on Sundays and workshops covering the likes of waste reduction, bike repair, and mending. 4750 N.
