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

An Introductory Guide To Decision-Makers


The Future

Utilisation will continue to grow as the preferred biosolids management practice because it is based on the fundamental concept of resource stewardship. Societies worldwide are recognising that there is an urgent need to change our thinking from resource consumption to ecosystem protection, and from disposal of so-called waste materials to the extraction and reuse of the valuable portion of these resources. The need for biosolids management systems in the developing world is particularly urgent. Many communities now provide water and sanitation services and they do not have a lifetime available to develop a biosolids utilisation system. Fortunately, it is possible to learn from the experiences of others, adapt these experiences to meet local needs and conditions, and accelerate the process. Most water-related associations, agencies and organizations such as the United Nations Environment Programme International Environmental Technology Centre (UNEP/IETC), the United Nations University International Network on Water Environment and Health (UNU/INWEH), the International Water Association (IWA) and the International Solid Waste Association (ISWA) can offer assistance and information.
