Biosolids Management: An Environmentally Sound Approach
for Managing Sewage Treatment Plant Sludge

An Introductory Guide To Decision-Makers

Treated sludge, known as biosolids, is widely produced in many countries. Once treated properly, sludge has important economic and environmental value due to its high concentration of organic nutrients, which make it valuable for use as fertiliser in agriculture or other practices. This booklet gives a general overview of the wastewater treatment process, as well as of the production of biosolids and their utilisation in agriculture. It should help decision-makers who are considering this environmentally sound technological approach to solving the problem of sludge disposal.
