About the Speakers
Dr Oscar K S Hui is a Lecturer at the Department
of Systems Engineering & Engineering Management
of City University of Hong Kong. He received his
BEng degree in 2002, MPhil degree in 2004 and PhD
degree in 2008 from the Department of Mechanical
Engineering of Hong Kong, University of Science and
Technology. Over the past 10 years, he has conducted
research in different areas related to energy and
environment, including Li-battery, supercapacitor,
electrodes for direct methanol hydrogen peroxide fuel cell, hydrogen production
by methanol steam reforming, solid-state lighting, desiccant cooling, and air and
water treatment. He has managed 15 research projects as Principal Investigator
with a total research grant of HKD 5.6 million. Currently, he has been collaborating
with colleagues in USA, Australia, Singapore, Japan, Korea, China, and Hong
Kong. Thus far, his research has led to one US patent application, five Korea
patent applications, 38 journal publications, and 44 conference papers.
Dr Zhi Ning (PhD in Environmental Engineering,
University of Southern California, USA) is currently
an Assistant Professor in School of Energy and
Environment at City University of Hong Kong. Before
joining CityU, he was research assistant professor
in Southern California Particle Center funded by US
Environmental Protection Agency. He has 10 years’
experience in air pollution technologies development
and aerosol related research. He has led and
participated in the R&D of miniature versatile aerosol concentration system, high
efficiency electrostatic precipitator, bipolar particle charger and high resolution
air pollutants chemistry and toxicity sampler etc.
Dr Carol S K Lin is a Visiting Assistant Professor
in the School of Energy and Environment at the City
University of Hong Kong. She graduated in Chemical
and Materials Engineering from the University of
Auckland, New Zealand with a 1st class honours
degree. Carol holds a PhD in Chemical Engineering
from the University of Manchester, England. She
worked as a postdoctoral researcher at the Centre of
Expertise — Industrial Biotechnology and Biocatalysis
(InBio.be) at Ghent University in Belgium.
Her current research interests focus on the valorization of food waste through
conversion into commercially valuable products such as bio-degradable polymer
and specialty chemicals.
Synopsis
Ozone Catalytic Oxidation (OCO) Technology for Degradation
of Dye in Water
by Dr Oscar K S Hui
Coloured industrial effluents from dyeing industries represent major
environmental problems because many dyes and their breakdown products are
toxic to aquatic life, and are carcinogenic and mutagenic to humans. Conventional
biological treatment systems are unsuitable to destroy colorants present in
these waters. In the case of physical-chemical treatments such as membrane
filtration, precipitation or adsorption, contaminants are only transferred from
one phase to another phase without solving the global environmental problem.
In this respect, OCO has become a new treatment alternative because of its
high removal efficiency and low energy consumption, enabling the removal of
colorants from complex effluents. In this presentation, the speaker will introduce
OCO technology for degradation of dye over nanoporous materials. Basic yellow
87 was selected as a target basic dye pollutant owing to its low biodegradation.
The proposed OCO technology offers three striking features: i) combination of
adsorption, ozonation and catalytic oxidation, reducing cost and enhancing
dye removal efficiency; ii) use of mesoporous material that can enhance mass
transport and diffusion and increase the degradation efficiency; iii) converting
dyes into carbon dioxide and water for less environment pollution and energy
consumption. The OCO technology could be of value to the textile industry,
providing cost effective mineralization process for the dyes in water.
Air Pollution Measurement and Control Technologies to Meet
the Environmental Challenges
by Dr Zhi Ning
With economy growth and population increase, air pollution has become one
of the most serious environmental problems in mainland China as well as Hong
Kong. In the Twelfth Five-Year Plan (2011–2015) laid out by Chinese central
government, environment protection has been listed as one of the seven strategic
industries, and protecting the environment is of paramount concern as China
attempts to restructure its economy to be less energy-intensive. With foreseeable
implementation of more stringent air quality and emission regulations, there will
be a huge market for new emission control and air pollution related technologies
such as more advanced air pollution measurement, vehicle emission inspection
and abatement, and pollution source control etc. This speech will present a few
promising air pollution technologies to meet such a challenge.
Valorisation of Coffee Grinds and Unconsumed Bakery Waste
from Starbucks Hong Kong for The Sustainable Production of
Chemical and Materials
By Dr Carol S K Lin
The School of Energy and Environment at the City University of Hong Kong has
recently started collaborating with coffee retailer giant ‘Starbucks Hong Kong’.
The partnership, which was facilitated by the NGO the Climate Group, will focus
on the valorisation of spent coffee grounds and unconsumed bakeries via bioprocessing.
The collaboration is based on a support scheme and part of the “Care
for our Planet” campaign: for every set of Care For Our Planet Cookies Charity
Set sold, Starbucks will donate HK$8 to the School of Energy and Environment of
City University of Hong Kong to support research on valorisation of food waste
for sustainable production of chemicals and materials.
The aim of the research is to valorise the disposed coffee grounds and unconsumed
bakeries to bio-plastics (poly-3-hydroxybutyrate, PHB) and succinic acid. This
can facilitate the development of biomass use in Hong Kong and reduce the
release of greenhouse gases and other air pollutants into the atmosphere. Such
a synergistic solution through the utilization of food waste for the production
of value-added products can then be adopted by the Hong Kong Government
as part of their strategy for tackling the food waste problem and for the
environmentally friendly production of alternative platform chemicals.
