Global attention has focused on improving waste circulation recently. Our lab is actively research on Waste-to-Energy, waste recycling, and development of adsorbents, landfill cover materials, and soil conditioners. Specifically, we focus on developing eco-friendly technologies aimed at mitigating environmental hazards, including proper waste management with the remediation of the contaminated heavy metals in soils, with particular emphasis on hydrothermal treatment (HT) technology.
