Uncovering algae biomass potentials : from wastewater to biostimulants

Cepec, Eva (author), Griessler Bulc, Tjaša (author), Istenič, Darja (author)

The need to minimize human impact on the environment encourages alternative methods and solutions which could provide new steps towards green transition. Population is growing and climate is changing which is causing distress in food production and to recycle resources is getting ever more important. It is already known that municipal wastewater is a nutrient-rich medium, furthermore there is great potential to implement new technologies for nutrient recovery. We must provide sustainable wastewater treatment and at the same time we must try to maximize utilization of all available resources found in wastewater. Wastewater is suitable for growing algal biomass which can later be used as biostimulants in crop production which is in line with the goals of circular economy. This article provides a short overview of several studies on algal wastewater treatment and types of biostimulants produced from algae biomass. Further research on algal biostimulants production using municipal wastewater need to be focused to pilot experiments and real wastewater since the majority of reviewed studies are done on the lab scale with synthetic wastewater.
