This study investigates the chemical and biological treatment of HTL-AP to enhance its valorization. Initially, the feasibility of an advanced chemical treatment (electrolysis) on the HTL-AP to recover plant-available nutrients was tested. Later, the effects of altering operational parameters, such as adding sodium chloride and sodium bicarbonate, adjusting the recirculation rate, and optimizing the chemical breakdown of organic nitrogen into plant-available nutrients, are explored. In the final stage of the process, nitrifying bacteria are introduced to assess their ability further to convert ammonia-nitrogen into nitrate-nitrogen in the aqueous phase. The results of this study contribute to a better understanding of how combined chemical and biological treatments can be utilized to valorize HTL-AP, offering a sustainable solution for the management of HTL byproducts and the recovery of valuable resources from waste. 2025-08 Text https://hdl.handle.net/2142/130192 Copyright 2025 Barbara Camila Bogarin Cantero Engineering Administration Agricultural & Biological Engr University of Illinois Urbana-Champaign Ph.D. Dissertation
