Greater Bay Can Improve Waste Usage, Say Experts

A group of civil engineering researchers has proposed setting up a platform to collate data on the generation of construction waste and demand for it across the 11 cities in the Greater Bay Area.

The group, made up of engineers working in various universities in the city, said this can help reduce waste in Hong Kong as most of the 19 million tonnes of material generated here now end up in landfills.

The engineers said to avoid this, governments in the bay area can make arrangements under which the material can be used in cities which are in need of this waste.

Professor KW Chau, head of Hong Kong University's real estate and construction department, said that will be a win-win solution for all the cities and in the long-run, Hong Kong could make use of the waste from these cities when it undertakes large-scale reclamation projects.

He told RTHK's Candice Wong that the generation of waste and projects that need the material may not take place at the same time. So it is better to have an arrangement covering a larger area, he said.
