Study confirms benefits of sludge re-use

Abstract

Wastewater management The study, undertaken by Frost & Sullivan, focused on the potential impact of the Guidelines for the Utilisation and Disposal of Wastewater Sludge. The first two volumes of this fivevolume set of guidelines have already been published while the remaining three are awaiting final government approval. The latest project was aimed at quantifying the potential impact of the guidelines on South African society by analysing current examples of wastewater sludge best practice that are aligned with the new sludge guidelines. From waste to resource The management of sludge (the solid, semi-solid or liquid residue generated during the treatment of domestic sewage in a treatment works) is the responsibility of local authorities. Wastewater sludge management in South Africa has been governed through a series of wastewater sludge guidelines over the past three decades. Each of these guidelines has aimed to assist stakeholders with management aspects of wastewater sludge handling.
