Beyond The Norm: Energy Recovery to the “MAX”

This paper discusses energy requirements and recovery effectiveness of two biosolids treatment systems:Anaerobic digestion and thermal drying for solids reduction and energy recoveryAnaerobic digestion followed by thermal conversion for energy recoveryThe analysis included for each alternative an energy balance and the life-cycle costs. Renewable energy credits, grants or incentives that may apply to each of these scenarios are also included.This information enables a comparison of two large-plant technology pairings, considering the current regulatory situation, government incentives, and the emerging environmental commodities market.
