Eco-Block Reduces Waste, Curbs Carbon Emissions and Turns Waste into Resources

About 180 tonnes of glass waste are disposed of in landfills every day in Hong Kong, accounting for 1.7% of municipal solid waste. The glass waste recycling rate is less than 20% here, lower than that in other East Asian territories such as Korea and Taiwan, and lagging far behind Mainland China where the recovery rate exceeds 50%. The problem is that it costs nothing to dispose of glass as Hong Kong has yet to implement its municipal solid waste charging scheme and there is a lack of a major glass recycling business.

The Pioneer of Solar Energy Application – Building Integrated Photovoltaics

In Hong Kong, buildings account for over 90% of electricity usage, creating over 60% of the city's carbon emissions. One of the critical measures to achieve the carbon neutrality target is to reduce coal-fired and natural gas-fired electricity generation, while increasing the proportion of electricity production from renewable energy. As a pioneer in renewable energy research, PolyU spares no effort in developing relevant technologies with applications and testing on the campus. A good example is the installation of solar photovoltaic systems at the Lee Shau Kee Building (Y-Block).
