Description
Coal – Related Regenerative Innovation for Concrete and Segmental Block Pavements
This research project investigated the technical feasibility of incorporating coal waste fines and bottom ash into concrete and segmental paving blocks as partial replacements for conventional fine aggregates. Laboratory results showed that optimised replacement levels can maintain or improve strength and durability while supporting circular-economy objectives through reduced aggregate consumption, waste disposal and production costs.

A digital wetland map and linked database were compiled for the Upper Olifants River Catchment from existing literature, existing wetland layers and aerial photography. Wetlands cover about 2 147 km2, some 14 per cent of the 15 158 km2 catchment. The wetland layer is about 70 per cent accurate and its attributes about 60 per cent, so it suits baseline screening rather than site assessment.

Sets out the authorisation route for leaving a pitlake as a closure landform, covering water use licensing, environmental authorisation and the wider legislative process. There is no single application that grants approval, and the route is long and partly duplicated, so several applications are required.
