Sustainability assessment of technologies for nutrients concentration/recovery from wastewater.


Abdulhamid's research is aimed at assessing the sustainability of the nutrients recovery technologies from domestic wastewater with a particular focus on urine where most of the nutrients are located (80% N, 50% P, and 60% K). Due to the dilution of these nutrients in urine, it is very difficult to transport and distribute large volumes. It is therefore imperative to develop technologies that enable the recovery and the conversion of these nutrients into a more concentrated urine-based fertiliser that is easier to apply and use. This results in a reduction of reliance on synthetic fertilizers, and thus of environmental burdens (e.g. eutrophication and algae blooms) associated with the release of 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 possibly QMRA (quantitative microbial risk assessment).
