Presentation
Abdulhamid's research aims to assess the sustainability of nutrient recovery systems from domestic wastewater, with a focus on urine, which contains the majority of nutrients (80% N, 50% P, and 60% K). Due to the dilution of these nutrients in urine, it is challenging to transport and distribute large volumes. It is, therefore, imperative to develop technologies that enable the recovery and conversion of these nutrients into a more concentrated urine-based fertilizer that is easier to apply and use. This results in a reduction of reliance on synthetic fertilizers and, thus, environmental burdens (e.g. eutrophication and algae blooms) associated with releasing these nutrients. Moreover, separating urine from the other wastewater fragments can reduce the amount of nutrients flowing to the WWTP, resulting in less treatment intensity and cleaner effluent. The assessment of these concentration technologies will be performed and carried out using a variety of tools such as; TIS (technology innovation systems), LCA (life cycle assessment), and SDM (System dynamic modeling).
