Power of Circular economy Waste Reuse
Here’s how we make anaerobic digestion more sustainable and efficient.




The problem
Modern problems require modern solutions
Those investing in biodigesters for renewable energy production soon encounter a major challenge: digestate, the byproduct of the process, accumulates in large quantities. Its high nitrogen content makes disposal costly and complex, with strict regulations to comply with.
Who we are
01
Nitrogen recovery
The digestate is treated through an innovative stripping system that efficiently separates nitrogen.
02
Conversion into microbial biomass
The recovered nitrogen is transformed into protein-rich microbial biomass (Single Cell Protein) through an aerobic conversion process.
03
Production of sustainable fertilizers
The resulting microbial biomass is used to produce high-quality microbial fertilizers and biostimulants.
04
Cost reduction and lower environmental impact
This process eliminates digestate disposal costs and enhances byproducts while complying with regulatory standards.
What is digestate?
Digestate is the organic residue resulting from the anaerobic digestion process, often characterized by high concentrations of ammoniacal nitrogen.
What are the benefits of your technology?
Our solution reduces digestate management costs by converting its nitrogen content into high-value fertilizers and biostimulants, promoting sustainability and complying with environmental regulations.
Is the process compatible with all biodigesters?
Yes, our technology is designed to be easily implemented in existing biodigesters without structural modifications.
