This document outlines the strategy, role, and industry impact of the South African Coal Ash Association (SACAA), with a focus on coal ash utilisation in South Africa. It highlights how organisations like Eskom and SACAA are working to transform coal ash from a waste product into a valuable resource for construction, infrastructure, and environmental applications. The report also explores different types of ash, their applications, and the regulatory landscape governing their use. With increasing pressure on sustainability and waste management, coal ash utilisation plays a key role in reducing environmental impact, lowering costs, and supporting economic development.
