How is the glass recycled?

Eco block

It is invented by HK Polytechnic University and has been manufacturing at a local eco construction material factory. The major constituents are recycled aggregates from construction and demolition waste, recycled waste glass and fly ash from power plants. The Eco-block is used for pavements. It has undergone three generations of development and the latest generation contains an air cleaning agent, titanium dioxide (TiO2), in block production. Titanium dioxide helps remove nitrogen oxides from atmosphere. When used it, the level of nitrogen oxides can be reduced by an average of 20%. Nitrogen oxides contain nitrous oxide, which is the third largest greenhouse gas contributor to overall global warming, behind carbon dioxide and methane.
