What they are used for
Stone Sludge & GME New Eco-Technology
When natural stones are processed to cut or grind, there are environmental pollution issues such as sludge formation, dust, and noise pollution.
Especially, the treatment of sludge from stone working mostly relies on the landfill method, leading to groundwater contamination.
Less developed water works area could be at greater risk of drinking water contamination.
Meanwhile, the fine-powdered stone sludge lacks the physical quality to mix well cement, making it difficult to recycle.
But applying special chemical compositions and using the technology from the ceramic industry, GME’s New Eco- Technology produces various kinds of low-cost and high-quality construction materials. The technology is regarded as being highly environmentally friendly and economical.
