PortionPac Chemical Corporation, Chicago, is an example of a future "business model." The product line is cleaning chemicals, but the company signs cleaning service contracts for buildings. The customers pay for cleanliness, not detergents.
So PortionPac uses small containers so that overuse is made difficult, and trains cleaning personnel in their use (and in how to do their work a little better). From a business view, the less cleaning agent PortionPac ships, the more money it makes on a contract.
In modified form, this kind of business model is the future. A common example is power companies helping their customers use less electricity to accomplish the same thing.
