Is flour mill pollution free industry?

No, flour mills cause substantial damage to the surrounding area. For example, in Minneapolis, MN where the flour mill industry emerged and dominated for most of the 19th century, St. Anthony Falls, upon which the industry was founded and powered by the water source there was significantly damaged. The river was transformed to supply the mills with energy and thus much of the natural landscape was destroyed or permanently altered. In addition, the flour mills dumped much of their waste products such as the explosive flour dust into the river which, when mixed with the water would create a paste like substance. This waste piled up and killed many of the ecosystems in the river, including many species of fish. It also created a disgusting smell that was unpleasant to residents living south of the river.
