About the Book Managing biosolids for reuse and not for disposal is the focus of this book. The emphasis is placed on environmental compliance where the goal is the processing of treated biosolids to the production of a waste product (biosolids ash) that has been discarded in the past and to demonstrate that this particular waste byproduct has some value. When biosolids ash is managed for reuse and is not disposed of in the traditional manner, all sides win, including the environment.
