What is it about?
Struvite precipitation is a promising way to help recover phosphorous from waste sources while producing crystals known for its slow-release properties, with fertilizer application. However, the need for a Magnesium source often creates problems, either its price or processual constraints. Many sources exist, but there was not a direct comparison between them, so the best option is defined. In this article the best source from those known until that moment was defined

Why is it important?
This article provided a definite answer on how different Mg sources compare for struvite precipitation in urine. Both yield and crystal properties were analysed. The results highlight the pros and cons of each and define the best Mg source, at least from those currently known, helping further investigations have a departure point.
Perspectives
An article highlighted how important it is not to look just at one specific detail when it compromises another. A midpoint that maximizes both is often preferred, and it is important to understand what may be the consequences of that midpoint.
