Use of wastewater-recovered struvite as a phosphorus fertiliser

IWN Webinar Series – 31 October 2024

Phosphorus is an essential element for all living beings including plants, yet over the last 60 years, the large-scale input of phosphorus from human activities and agricultural intensification has significantly contributed to eutrophication and the depletion of non-renewable phosphate rock reserves. However, recycling and recovering phosphorus from wastewater and reusing it as a fertiliser is a promising strategy to mitigate eutrophication and reduce reliance on phosphate rock reserves.

Struvite is recovered from municipal wastewater through controlled precipitation and presents a promising long-term solution as a sustainable and renewable P source. Struvite contains about 12% P, 6% N, 10% Mg and small amounts of micronutrients, making it a promising alternative P fertiliser.

In this seminar, Manish will present the findings from his PhD research project titled “the evaluation of wastewater-recovered struvite as an alternative phosphorus fertiliser for chickpea and wheat growth and yield”. This project is a component of Biosolids Training Centre’s 2B project – produce a range of high value tailored fertilisers from waste streams.

About the speaker

Manish Sharma has recently submitted his PhD thesis and now working as a research associate at The University of Western Australia. His postdoctoral research will investigate furthermore about the use of struvite blended with other waste products as a phosphorus fertiliser in other crop species.
