easat-3020	Martins, Ramiro J. E. 	Ultrasound-driven anaerobic digestion to improve energy production from crude glycerol	2024	10	.pdf	application/pdf	3964	219	52	References [1] Z. Pirzadi, F. Meshkani, From glycerol production to its value-added uses: A critical review, Fuel, vol. 329, pp. 1-48, 2022. However, for feed with glycerol concentrations of 3.2% and 1.7%, methane production was considerably low, indicating that ultrasound pre-treatment's impact was insignificant.	cache/easat-3020.pdf	txt/easat-3020.txt
