Abstract
Abstract The idea of growing microalgae in wastewaters emerges from the idea of resource conservation and the recovery of nutrients. In fact, microalgae are able to take up nitrogen, phosphorus and carbon from wastewaters, even adsorb metals, and in many cases, can be co‐cultivated with various bacteria that are prevailing in municipal wastewater treatment plants. The cultivation of microalgae in municipal wastewater has been known for about half a century and investigated accordingly. Despite this long history, there are still many questions to answer before this technology will be ready for implementation in large‐scale projects. In this review, recent developments are presented. One crucial point in developing a viable process out of wastewater grown algae is the downstream processing of the accumulated algal biomass. The authors decided to focus on hydrothermal carbonization (HTC) as a processing strategy. HTC uses wet biomass and relatively mild process conditions to produce an energy‐rich biochar and a liquid fraction that can be further processed to higher‐value substances. The latest findings in the carbonization of microalgae are highlighted in the second part of this article.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
