Dr. Chew Kit Wayne Publishes 2 SCI Q1 Articles on Sustainability


Research Management Center congratulates Dr. Chew Kit Wayne from School of Energy and Chemical Engineering, Xiamen University Malaysia on publishing two research articles in Environmental Pollution and Chemosphere, as the first and corresponding author.

Entitled “Abatement of hazardous materials and biomass waste via pyrolysis and co-pyrolysis for environmental sustainability and circular economy” and “Algae utilization and its role in the development of green cities”, the two articles were co-authored respectively by Assoc. Prof. Dr. Ong Wee Jun and Assoc. Prof. Dr. Rashmi Walvekar.

The first article provides a comprehensive review of the pyrolysis and co-pyrolysis of biomass and harmful wastes, introducing innovative techniques to combat the global crisis of waste generation. The processes use hazardous waste materials and biomass as feedstock to produce gas, char and pyrolysis oil, stabilizing heavy metals in wastes and solve the energy and waste management problems. Several techniques were studied including products of pyrolysis and co-pyrolysis, pyrolysis reactors and reaction principle. Its useful product, pyrolysis oil, has been evaluated for its upgradation, through hydrogenoxygenation, emulsification, esterification, ultrasonic cavitation and plasma catalysis. It is noteworthy that hazardous materials, such as biomass, plastics (polymers), medical wastes and waste tires, can be used as feedstock in pyrolysis and co-pyrolysis. This can contribute greatly to pollution mitigation through thermochemical management and waste utilization.

In the second article, the authors argue that with the rapid urbanisation happening around the world and a massive demand for clean energy resources, green cities play a pivotal role in building a sustainable future for the people. The continuing depletion of natural resources has led to the development of renewable energy with algae as one of the promising sources. With a high growth rate and strong bio-fixation ability, algae and microalgae can gather energy from sunlight and carbon dioxide and transform the nutrients into biomass and oxygen. Thus, it is possible to create green cities through algae cultivation, which will act as a carbon sink to reduce global warming and produce valuable compounds. The challenges of using algae and the future prospect of Sustainable Development Goals and the economy are also addressed in the study.
