Description
Coal waste, including fines and fly ash, can be safely and effectively incorporated into asphalt mixes without compromising mechanical or environmental performance. Asphalt containing coal waste demonstrates comparable or improved strength, durability, and resistance to moisture damage, while delivering cost and sustainability benefits. This approach supports circular economy principles by reducing waste, lowering reliance on natural aggregates, and improving material efficiency in road construction.

Ecological integrity of a Mpumalanga wetland affected by coal mining was assessed before and after rehabilitation, using water quality, bacterial consortium, freshwater algae and vegetation indicators. The work sits within a wider programme to give the coal sector and regulators practical ways of limiting and mitigating mining impacts on wetlands.
