At the moment the biological processes of organic waste treatment (anaerobic digestion) that take place in waste treatment plants occur spontaneously, with minimal technological control and no biotechnological control. This generates multiple unknowns.

One of the main enigmas to be solved and on which the optimization and improvement of these processes is based on the control and knowledge of the populations of microorganisms involved in the process. In this sense, given their heterogeneity and spontaneity, as well as their relationship and dependence on operational factors, it is necessary to carry out research under the most controlled conditions as possible, so that the results and methodologies developed can allow extrapolating conclusions and future operating strategies.

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.

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.
