Enhancement of Syngas Production in Co-Pyro-Gasification of Biomass and Plastic Waste Materials: Computational Study (2022)
Preprint / Working Paper
Darkwa, J., Kwawu, C., Corner, J., Kemausuor, F., Adei, E., Agyekum, K., & Boateng, I. D. Enhancement of Syngas Production in Co-Pyro-Gasification of Biomass and Plastic Waste Materials: Computational Study

The process of co-pyro-gasification of biomass and plastics appears to have the potential for increasing syngas production for power generation and thus minimizing the impact of plastic waste on the environment. This study was based on co-pyro-gasifi... Read More about Enhancement of Syngas Production in Co-Pyro-Gasification of Biomass and Plastic Waste Materials: Computational Study.

Evaluating urban heat island mitigation strategies for a subtropical city centre (a case study in Osaka, Japan) (2022)
Journal Article
Zheng, T., Qu, K., Darkwa, J., & Calautit, J. K. (2022). Evaluating urban heat island mitigation strategies for a subtropical city centre (a case study in Osaka, Japan). Energy, 250, Article 123721. https://doi.org/10.1016/j.energy.2022.123721

Urban heat island (UHI) effects were first observed in London in the 19th century. The urban heat island is identified by developing higher temperatures in urban areas than the surrounding rural areas that directly surround them. However, there are s...
