China turns coal waste into construction materials in major recycling push

In the southeastern county of Gaoping, located deep within China's premier coal province of Shanxi, a massive new recycling facility has quietly begun operations. It transforms the waste into high-value industrial and building materials.

Reportedly, its daily output sounds like a standard quarry operation: 1000 tonnes of sand, gravel, and unburnt bricks. The raw material was extracted from coal gangue - the ultra-hard, toxic rock waste left after mining and washing coal.

China's coal gangue is expected to be around 7 billion tonnes. Left unmanaged, coal waste routinely triggers water contamination, airborne dust pollution, and spontaneous fires. Less than 60 per cent of this mountain of rock was ever reused.
