PhD in Chemical Engineering


Biography

Passionate about leveraging chemical engineering principles for environmental sustainability, I am an accomplished award-winning Chemical Engineer. I am currently working on my PhD in the Department of Chemical Engineering at the University of Sydney. Holding an MSc in Environmental Sustainability and Green Technology (Distinction) from Keele University, I am equipped with a strong foundation in sustainable technologies, environmental politics, and water resources. My research expertise lies in designing sustainable concrete with a focus on low carbon emissions. My expertise extends to alkali-activated materials and graphene synthesis using low-impact methods. I am honored to have been recognized as the IChemE NW Young Chemical Engineer of the year 2023.

Project description

Evaluation of Performance of Access Chamber Constructed with Specialty Cement with Repurposing Waste

In this project, I will be developing low-carbon concrete made from repurposed waste for aggressive sewer environments. This research focuses on addressing sewer corrosion induced by microbiologically influenced corrosion (MICC) by developing specialty concrete from repurposed waste to enhance the durability of sewer structures. By utilizing repurposed waste and mine tailings, the study aims to reduce carbon emissions and waste generation while combating aggressive environments in sewer infrastructure. Beyond corrosion mitigation, the research has broader implications, including the development of educational modules and the potential commercialisation of access chambers.

What led you to undertake an industry-led research project?

To gain practical experience in my desired industry and improve my skills while collaborating with industry professionals, I aim to complete an industry-led project that addresses a relevant problem.

I completed my master’s degree at Keele University in the UK, where I achieved a distinction in Environmental Sustainability and Green Technology. For my dissertation, I worked on sustainable concrete made from geopolymers, which is similar to the topic of my current PhD research.

Once you have completed your PhD, what’s next?

After completing my PhD, I would like to work in industry.

How will your research benefit Australia’s concrete ecosystem?

In my research endeavour, I am focusing on developing low-carbon concrete by using repurposed waste materials. I plan to achieve this by using alternative raw materials such as waste and mine tailings. By doing so, I aim to reduce the carbon footprint created by traditional concrete manufacturing processes. These waste materials will replace conventional aggregates and cement, which will help reduce reliance on virgin resources and minimize the environmental impact.

The low-carbon concrete formulations that I will create will be specifically designed for constructing access chambers. Repurposing waste materials for concrete production will not only promote sustainability but also help address waste management challenges by reducing the amount of waste sent to landfills.

By replacing traditional aggregates and cement with repurposed waste materials, the resulting concrete mixtures will exhibit enhanced environmental performance without compromising structural integrity or durability. This research aims to contribute to the circular economy, where waste streams such as construction debris, industrial by-products, and mine tailings can be repurposed and used efficiently.
