Inside a laundromat in Brooklyn, N.Y., it’s now possible to buy standard cleaning products like Pine-Sol without having to buy a whole new container. Instead, customers bring old containers back and refill them. Not only is Algramo, the business behind this idea, reducing single-use plastics, it is eliminating “the poverty tax” phenomenon, where consumers buying the smallest version of a product pay much more per unit than customers who buy in bulk. This works like a gas station, where the consumer can buy as little or as much of the product as they want at the same price per unit. It's is intentionally designed to attract cost-conscious consumers who might otherwise be late-adopters for this service.
