Speech Title: Green chemistry: A case for sustainable production of biofuels from non-food substrates

Abstract: As the reality of the finite nature of fossil derived feedstock chemicals and fuels sets in, coupled with the need to reduce greenhouse gas emissions to help slow down global warming, green chemistry, also known as sustainable chemistry, is gaining the attention of scientists, engineers, and policy makers as an area of study that holds promise in our quest for sustainable production of biobased feedstock chemicals and fuels. Successful application of green chemistry to sustainable production of feedstock chemicals and fuels is expected to provide global community energy security and help mitigate excessive greenhouse gas emissions into the environment. Biobased fuels and feedstock chemicals include but are not limited to ethanol, butanol, propanol, isopropanol, pentanol, hexanol, 2,3-butanediol, 1,3-propanediol, succinic acid, lactic acid, H2, and CH4. For this talk, however, the focus is on sustainable bioproduction of butanol. Meanwhile, food crops such as sugarcane, corn and other starchy crops are the major renewable substrates that are currently used, in enormous quantities, to produce biobased feedstock chemicals and fuels. These substrates also serve as feed for livestock and food for humans and other consumer products, which create competition and potentially drives up cost. From economic and environmental view, non-food substrates such as lignocellulosic biomass (LB) or agricultural residues, and food rejects, that are generally considered as waste with some disposal issues are considered better choices than food crops. Consequently, this talk will elaborate on rationale and significance of sustainable butanol production from non-food substrates, technologies of production, bottlenecks associated with butanol production, and strategies to advance commercial production of biobutanol.

Prof. Jia-Qian Jiang

Glasgow Caledonian University

Biography Sketch: Professor Jiang has been active in water and environmental science and engineering research more than three decades. His main interest and expertise include the development and use of water treatment chemicals (adsorbent, coagulant, disinfectant, and oxidant), design and optimization of water treatment unit processes (e.g., coagulation, filtration), nutrients recovery from wastewater (e.g., phosphorus recovery), and degradation of emerging micro-pollutants in aquatic environment. 

He is a member of UK EPSRC Peer Review College; a research assessor of The Carnegie Trust for Scottish Universities; a member of expert committee of EU Research for Innovation; an external PhD examiner at various universities; and an invited international research proposal assessor. As a principal investigator and a PhD supervisor, he leads and manages his research team to initiate, conduct and successfully complete various research projects. His research has resulted in a number of granted international/UK patents and journal articles and has transferred the knowledge to industries aiming at resolving their practical issues. In addition to this, his research outputs have wide impact on the academic communities (ORCID ID: https://orcid.org/0000-0003-3607-8910).

Speech Title: Safe and Clean Water for All 

Abstract: Water resources are essential the core of achieving United Nations Sustainable Development Goals (UN SDGs), as they are indivisibly linked to agriculture, food security, health, etc., and ensure economic development. However, water pollution, urbanization, population growth, and climate change have placed considerable pressure on water resources. About 748 million people still do not have access to an improved source of drinking water, and water demand for industrialization is expected to increase by 400% between 2000 and 2050. This talk aims to assess the opportunities and challenges we are facing and the efforts we can make to achieve the UN SDG 6 through the technology development, global financial investment and establishing legal framework to ensure sustainable water management and enhancing and improving access to safe water supply, sanitation, and hygiene services.

Speech Title: Using permeable pavements to harvest stormwater for non-potable water uses in buildings

Abstract: The increase of impermeable surfaces has caused an increase in the frequency of flooding in urban centres. Such fact shows that traditional urban drainage systems are becoming outdated. Also, global warming may lead to an increase in short-term floods since there is a strong correlation between peak rainfall intensity and high temperatures. As the number of floods has been increasing, it is necessary to use new urban drainage systems, capable of restoring the natural hydrological cycle in urban centres. Permeable pavements are examples of systems that fulfil this function, by treating water locally and reducing the possibility of overloading stormwater distribution networks. The objective of the speech is to discuss and present some case studies to evaluate the use of permeable pavements to harvest stormwater for non-potable water uses in buildings.

Speech Title: Next Era in Recycling Concrete

Abstract: Construction and demolition waste is one of the largest contributors to landfills. Unfortunately, the utilisation of construction and demolition waste as recycled aggregate in concrete is not common. CO2 Concrete is invented by injecting CO2 into recycled aggregate for concrete applications. The overall performance of CO2 Concrete has matching performance as virgin concrete. The enhancement of CO2 Concrete alongside the consistency that the material can display provides a great deal of future value
