The Bio Gro Division of Wheelabrator Water Technologies Inc. has traditionally been involved in recycling biosolids from domestic wastewater treatment plants. The biosolids, or primarily organic residuals that result from the treatment of wastewater, have long been used in agriculture as a soil conditioner, fertilizer, organic lime material and also for other soil fertility practices. It has long been known that residuals from certain industrial wastewater processes are very high in nutrients and organic matter which can also be successfully used in agricultural activities. One of these industrial biosolids with well-documented agricultural value is the organic residual from the treatment of wastewater from pulp and paper mills. Most pulp and paper producers in the US recognize the value of pulp and paper biosolids as a material that can fertilize their own tree stands or can be used in normal agricultural practices. In 1995, Bio Gro entered into a contract with a two large pulp and paper mills in Maine for the management of its pulp and paper biosolids. Bio Gro was responsible for implementing the beneficial use options for a mixture of primary and secondary biosolids from the wastewater treatment process which was combined with combustion ash from the facility`s power generation facilities. The contract included the layout of spreading areas, mixing of the residuals and spreading the material on the sites. This paper will explain the process that Bio Gro employed to manage the pulp and paper biosolids generated at the mill.
