Circular economy in urban services
The main objective of this project is to design and develop a new anaerobic digester, on a small scale, to identify and analyze the populations of microorganisms involved, and to model the microbial processes that occur in each of the biomethanization stages.
In this way, we achieve a biotechnological control that did not exist until now. All this, with the purpose of increasing the biogas production flow and its quality, reducing the amount of rejection destined to landfill and reducing its biological and chemical reactivity, making it more inert.
With this project, we promote the circular economy in urban services by having at the end the best use of waste for the reduction of waste that ends up in landfills.
