Myriam Esteban's doctoral thesis analyses the combination of experimental techniques and mathematical tools for the optimal management of this type of waste.
Myriam Esteban's doctoral thesis for the Department of Environmental Engineering, titled "Anaerobic co-digestion of sludge in WWTPs with different types of organic waste: the combination of experimental techniques and mathematical tools", is a substantive analysis of co-digestion as an alternative treatment for some types of organic waste. Currently, the management of such waste is not optimal from a technical and environmental point of view, according to the guidelines set by current legislation.
Its full-scale application could result in significant improvements in the management of wastewater treatment plants, both in economic and sustainability terms. In addition, it would contribute to the recovery of energy from waste that is currently sent to landfill.
The thesis also presents an experimental analysis carried out at pilot scale to determine the viability of dry anaerobic digestion. This technology has the potential to be exploited in real plants and it has well-known advantages over conventional wet digestion systems.
The most innovative aspect of the study lies in the combination of experimental studies and mathematical tools in order to broaden the applicability of existing mathematical models.
Dr. Esteban has developed a methodology that will ultimately promote the application of simulation as a tool to help with the operation of real reactors.
