Environmentally friendly paving block that can keep the air clean



More than 300 tonnes of glass wastes and thousands of tonnes of construction material are generated daily in Hong Kong and are disposed to the landfill sites which are taking up much of HK’s precious landfill resources. Eco-block is an environmentally friendly construction material which is made by a patented technology developed by PolyU. It effectively uses recycled glass and construction waste as major constituents in the production of concrete blocks to remove air pollutants, such as nitrogen oxides (NOx). It not only reduces the disposal of waste, but also conserves the use of natural resources, such as river sand.
