Producing biofertilizers using waste from agriculture and livestock in a circular bioeconomy

Using microalgae for agriculture farms and livestocks and further biofertilizers production and application within circular economy
The use of livestock and poultry manures as fertilizers is regarded as an important action in the development of circular agriculture. However, long-term fertilization with manure is accompanied with heavy metals accumulation, pathogens contamination, and ammonia toxicity, which may cause the decline of soil quality and crop productivity.
To address the aforementioned problems, in this project, we will propose a technical route
drainage water
microalgae are employed as a carrier transporting nutrients in manures and drainage water to soil and crops.
