39.4.2 Fermentation of agri-food waste. Fermentation is a process of converting the organic material into various products using different microbes, such as bacteria and fungi. There are several different products that could be produced through fermentation, for example, fuels, chemicals, pharmaceuticals, etc.

2012/10/1/ · Fermentation yielded 670 NL biogas/kg volatile solids (VS) with the CSTR and 550 NL biogas/kg VS with the FBR. The productivities were 3.9 NL biogas/ (L*d) with the CSTR and 3.4 NL biogas/ (L*d) with the FBR. The average methane concentration was approximately 60% for both reactor systems.

2015/1/1/ · The top layer (80% butanol and 20% water) is returned to the butanol column, and the bottom layer (4% butanol and 96% water) is returned to the beer column. Approximately 35,000 lb stream is consumed for every ton of solvents produced. Fig. 24.22. Process flow sheet of butanol-acetone-ethanol fermentation.

2023/1/1/ · Abstract. Agricultural activities at farm as well in processing industries generate vast amount of waste annually. The resulting residues are rich in nutrients and compounds with potential biological applications, therefore would entail exclusion from being termed as “waste.”. Agricultural residues encompass residues like leaves, twigs
