ABOUT US

A team from Western Sydney University has developed a new process that injects carbon dioxide into recycled aggregate to improve its bonding, and thus performance of recycled concrete. This benefits the environment in two ways:

  • Using carbon dioxide which would otherwise be released into the atmosphere, worsening global warming and climate change issues; and

  • Reducing landfill space by turning construction waste into construction material, i.e. recycled concrete whose performance is similar to virgin concrete.

 

This process can bring direct benefits to concrete batching plants as recycled concrete can be effectively used. Many leading concrete suppliers have researched this capability but none have been successful.

Associate Professor Khoa N. Le

The co-inventor of CO2 Concrete.

Khoa received his Ph.D. in October 2002 on wireless communication from the Department of Electrical and Computer System Engineering, Monash University, Melbourne, Australia. His research interests are in wireless communications with applications to structural problems, image processing and wavelet theory.

Khoa is currently working as a Associate Professor at School of Computing, Engineering and Mathematics, Western Sydney University, Australia, and Honorary Professor at Posts and Telecommunications Institute of Technology, Ho Chi Minh City, Vietnam.

Professor 

Vivian W.Y. Tam

The co-inventor of CO2 Concrete.

Vivian received her Ph.D. on recycled concrete from the Department of Building and Construction at City University of Hong Kong in 2005. Her research interests are in the areas of sustainable construction, focusing on recycled concrete, environmental management in construction, green buildings and life-cycle assessment.

Vivian is currently working as the Associate Dean (International) at School of Computing, Engineering and Mathematics, Western Sydney University, Australia and Honorary Professor at College of Civil Engineering, Shenzhen University, China.

Ms Weiqi Xing received her MSc on sustainable construction from the Department of Built Environment, Xi’an-Jiaotong Liverpool University, Suzhou, China in April 2020. Her research interests are in the fields of sustainable construction on lean construction management, life-cycle assessment and Building Information Modelling. Weiqi is currently doing her Ph.D. research project at School of Engineering, Design and Built Environment, Western Sydney University, aiming to evaluate the sustainable performance of recycled concrete by using life-cycle assessment method.

 

Ms Mingxue Ma received her MSc on construction and demolition waste management from the School of Built Environment, Western Sydney University, Sydney, Australia in July 2020. Her research interests are in the fields of construction and demolition waste management and price of recycled concrete. Mingxue is currently doing her Ph.D. research project at School of Engineering, Design and Built Environment, Western Sydney University, aiming to evaluate dynamics impacts of possible factors on the price of recycled concrete.

Dr. Anthony Butera received his Ph.D in September 2020 on CO2 Concrete from the School of Built Environment at Western Sydney University located in Sydney Australia. His research focus is on the generation of practical, environmentally friendly, and sustainable concrete. Anthony is currently working as an associate lecturer in the School of Engineering, Design and Built Environment at Western Sydney University.
