Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 17 ottobre nell’aula Fassò (Edificio 4A), dalle 17:15 alle 18:30 CET.

PhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento.

La speaker Gaia Boniardi condurrà un seminario dal titolo “Why should we recover P from sewage sludge? How can we get it?”. 

Al termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento.

Sarà possibile seguire la conferenza anche online al seguente link.

Abstract 

Phosphorus is an essential element for life and its supply is expected to be critical soon. The increasing demand for fertilizers is gradually depleting the phosphate rocks, which are non-renewable resources concentrated in a few countries. On the other hand, the population growth and the rapid urbanization are putting the wastewater treatment plants under strong pressure, who are dealing with huge amounts of sewage sludge to dispose of every year. To tackle this issue, in the view of circular economy and sustainable development, phosphorus and nutrient recovery from sewage sludge is a promising option. The goal of this research is to optimize the phosphorous recovery from sewage sludge ash via wet chemical extraction. Experimental results underlined the influence of wastewater treatment layout and combustion process conditions on phosphorus extraction, while the heavy metals decontamination played a fundamental role in the production of high-quality recovered material.

Speaker’s bio

Gaia is a PhD Candidate in Environmental and Infrastructure Engineering (36° cycle) at Politecnico di Milano. In 2020 she got a Master of Science in Environmental Engineering, and she is currently working on nutrient recovery from waste, in particular phosphorus from sewage sludge ash. In her free time, she loves swimming, surfing, and traveling.
