Hydrogen Production by the Thermophilic Dry Anaerobic Co-Fermentation of Food Waste Utilizing Garden Waste or Kitchen Waste as Co-Substrate

Waste Management by Anaerobic Digestion of Kitchen Waste- A Review

Kitchen waste (food waste) collected from hostels and canteen has high calorific and rich nutritive value to microbes due to which efficiency of methane production can be enhanced. Biogas (Green energy) as an energy source is cost effective and generates a high-quality renewable fuel. Biogas contains around 55-65% of methane, 3040% of carbon dioxide. Methane has a calorific value of 10 kWh/Nm 3...

Process Evolution of Dry Anaerobic Co-digestion of Cattle Manure with Kitchen Waste

Manure residues have been identified as a major source of environmental pollution. Traditionally, the waste has been disposed directly or after composting, as soil amendments in the agricultural industry. Since this practice has resulted in the degradation of air, soil, and water resources, new regulations for protecting the environment have been promulgated to control land application of anima...

Inhibition of Thermophilic Anaerobic Digestion of Waste Food by Long Chain Fatty Acids and Propionate

Boosting dark fermentation with co-cultures of extreme thermophiles for biohythane production from garden waste.

Proof of principle of biohythane and potential energy production from garden waste (GW) is demonstrated in this study in a two-step process coupling dark fermentation and anaerobic digestion. The synergistic effect of using co-cultures of extreme thermophiles to intensify biohydrogen dark fermentation is demonstrated using xylose, cellobiose and GW. Co-culture of Caldicellulosiruptor saccharoly...
