Technological options for safe resource recovery from fecal sludge

Abstract

Fecal sludge (FS) contains important quantities of organic matter and nutrients that are valuable for agricultural production. Several approaches have been attempted over time for recovery of these assets. Presently, resource conservation and proper use of available materials are highly valued practices. This document describes technical solutions for the recycling of FS to benefit agriculture; this is particularly important for developing countries where there is an urgent need to enhance, at low cost, soil fertility for agricultural purposes.
