Reviewer 2 Report
Thank you for the opportunity to review a paper entitled: "Enhanced phosphorus recovery as vivianite from anaerobically digested sewage sludge with magnetic biochar addition."
The paper's topic is of interest and imposrtant since the dwindling supply of phosphorous is observed in worldwide agriculture. The writing of the manuscript is proper and understandable.
Minor remarks: Line 30, abstract - remove the space between number and Celcius.
Introduction: the technical part of the introduction is adequately written. However, the first paragraph could be expanded - showcasing how large the problem with dwindling phosphorus content in soils and/or problems with introducing new emerging contaminants to soil with sewage sludge application could bring a broader spectrum of readers to the authors' paper. Some of the references are quite old, and both in the introduction as well as in the discussion section, the manuscript would benefit greatly by adding more recent papers.
The materials, methods, and results are very clear and detailed.
