New research from McGill Bioresource Engineering!
Researchers from the Department of Bioresource Engineering and the Biomass Production Lab have published new research in the Journal of Environmental Quality exploring the environmental behaviour of bio-receptive porous concrete.
The study examined how nutrients and trace metals are released when the material comes into contact with water over 12 weeks. Researchers observed an initial “first flush” of elements, followed by a rapid decline and stabilization. Trace metal concentrations remained very low after the initial phase, suggesting the material becomes increasingly chemically stable over time.
🌱 Why does this matter? Porous concrete has potential applications in stormwater management, water filtration and hydroponics. Understanding how it interacts with water is an important step in determining whether it can be safely and sustainably used in real-world applications.
Congratulations to Tangina Aktar Tamanna, Sarah MacPherson, Philip Wiredu Addo, ABM Shahed, Manish Ojha and Mark Lefsrud on this contribution to sustainable agriculture, engineering and environmental research!
