Purdue researchers covert aquaculture sludge into biofuel using AD
In Indiana, converting aquaculture sludge with a natural microbial process into a viable renewable biofuel presents a mind-numbing chess match of biochemical variables. This process — anaerobic digestion — involves microbes operating in a no-oxygen environment.
Researchers from Purdue University are steadily developing new strategies for controlling the complex variables of anaerobic digestion, a naturally occurring process. They have contributed three publications on anaerobic digestion to scientific journals in the last year alone.
Two of the publications from their previous work explore the optimal mixing ratio for anaerobic codigestion of aquaculture sludge with corn residue and with dairy manure. The third publication assessed the status and future direction of a new research trend: applying biochar and nanomaterials to anaerobic digestion.
The three papers begin to fill significant gaps that the team identified in the anaerobic digestion research literature. In their new Biomass and Bioenergy paper, they noted that no systematic evaluation of anaerobic codigestion of aquaculture sludge and corn residue had appeared as of May 2025.
