Land reclamation is one of the most effective solutions to address the severe problem of land shortage. By 2023, the total reclaimed area in Hong Kong is nearly equivalent to the whole area of Hong Kong Island. In Lantau Tomorrow Vision, there will be over 1700 hectares of new reclaimed land in the next 20-30 years, in which, the shortage of fill material will be a great challenge. In this talk, different ways of recycling waste (including mechanically using rubber, chemically using ashes and biologically stabilized dredged marine deposits) to improve ground and serve as backfill materials will be discussed. These green technologies could reduce carbon emissions, contributing to carbon neutrality, and promoting green and sustainable reclamation.

Clean water and clean air are vital for public health. This project focuses on developing high-efficiency and environmentally sustainable filters for removing harmful air/water pollutants. The team has developed novel architectures and functionalities for the filters to achieve high permeance, high removal efficiency, and excellent reusability.
