Modelado de la biodegradación en biorreactores de lodos de hidrocarburos totales del petróleo intemperizados en suelos y sedimentos (Biodegradation modeling of sludge bioreactors of total petroleum hydrocarbons weathering in soil and sediments)

Anaerobic digestion of agro-industrial waste: Anaerobic lagoons in Latin America

“…Anaerobic digestion waste-to-energy (WtE-AD) processes are suitable for treating AW (Monroy-Oropeza et al, 2020) In developed countries such as Italy, Germany, the United Kingdom, France, and The United States, energy from these technologies accounts for considerable contributions of their national electricity consumption matrix: 7.9 (Benato & Macor, 2019), 7 (FMFA, 2019), 5.5 (Raugei et al, 2020) 4.5 (IEA, 2018) and 4%, respectively; corresponding to the management of 81 (Benato & Macor, 2019), 90 (Achinas et al, 2017), 80 (EA, 2001), 73 (Business France, 2017, and 53% of the total AW generated (mainly from livestock and agriculture). These processes are characterized by operating in a co-digestion regime through AW and energy crops, reaching high yields of 400 to 700 L CH 4 kg VS −1 .…”

Effects of different nitrogen sources on methane production, free ammonium and hydrogen sulfide in anaerobic digestion of cheese whey with cow manure

“…The high consumption of fossil fuels to meet the demand for energy and the growing scarcity of resources is causing civil and international conflicts, and negative effects on the environment such as global climate change (Ahmad and Zhang, 2020). The process of anaerobic digestion is a technology that has been given much attention since this process allows the biological conversion of organic wastes into biofuels such as biogas which is a mixture of mainly methane and carbon dioxide (Zhao et al, 2020;Monroy et al, 2020;Hernández et al, 2021).…”
