China Achieves Comprehensive Clean Utilization of Coal Wastes

The project – in Gaoping, a county-level city in Shanxi’s southeast – is producing 1,000 tonnes per day of building and industrial materials, including sand and gravel aggregates used in construction, according to the local government.

In an article published in mid-May, the provincial authorities said the materials were derived from the main solid waste generated during mining and washing, called coal gangue.

By cracking the tough bone of coal gangue, China has almost achieved the comprehensive clean utilisation of coal wastes – from contaminated water through exhaust gases and now solids.
