The talk will give an overview of the major environmental challenges facing Hong Kong and the opportunities such challenges open up.  It will also cover the newly established Environmental Academy in the Environmental Protection Department and how this may contribute to advancing environment

The need to reduce dependence on fossil fuels and minimize greenhouse gas emissions has led to increasing research on sustainable renewable energy source, including bioenergy. However, commercial scale of bioenergy production is severely constrained by investment risk and uncertainty.

Nanotechnology has contributed to all levels of scientific and technological development. It enabled many of the current state-of-the art materials technologies for energy storage, conversion, conservation and energy efficiency.

Food cooking contributes a major fraction of urban particulate matter. In particular, the organic emissions from food cooking are complex and poorly understood. In this work we characterize the intermediate and semi-volatile organic emissions from heated cooking oil.

Pollutant concentrations within deep urban canopies are affected by regional and local sources. Little is known, however, about how the balance between them changes with height.

Water-soluble organic matter accounted for an important part of the atmospheric fine particles and might have great potential impact on the formation of haze.

Despite much research in past decades, uncertainties in both climate impacts and health effects of atmospheric aerosols remain large.

Already in the ‘40s and ‘60s of the past century several microorganisms were discovered to be producers of biological detergents.

We live in a society with an increasing appetite for consumer goods but in a world that has limited resources. Our current linear economic model is based on the extraction of resources from the earth, processing to make articles and then use followed by disposal.
