summary.jpgIn the context of the circular economy, the wastewater treatment field is shifting to consider wastewater as a valuable resource rather than a hazardous waste. In particular, during the last two decades there has been a growing interest in microalgae-based wastewater treatment systems, specifically in the potential valorization of the microalgae biomass to obtain valuable bioproducts such as bioenergy, biofertilizers or bioplastics. Recent studies indicated that microalgae and cyanobacteria can have biostimulants and biofertilizers assets, generating multiple benefits to the agricultural sector. Indeed, agriculture today is facing several issues that jeopardize environmental sustainability. The overuse of synthetic agrochemicals has resulted in massive ecological degradation throughout the world. In a context of growing global population and change in consumption patterns, there is a need for cost-effective and sustainable solutions to increase crop yields, and biostimulants and biofertilizer can play a significant role.

The CYRCLE project aims at investigating and evaluating the sustainable and cost-efficient production of biostimulants from cyanobacteria biomass cultivated in wastewater. The project promotes resource recovering from waste streams within in the framework of a circular bioeconomy.
