Effect of the solid content on biogas production from Jatropha curcas seed cake
Anaerobic conversion of Jatropha curcas seed cake was studied in a fivelitre working volume batch reactor at 30°C. Over a 60day operating period, a slurry of seed cake in water at a 1 : 20 seed caketowater ratio showed the highest methane yield of 296 litre methane/kg Chemical Oxygen Demand (COD) degraded (or 156 litre/kg of Jatropha curcas seed cake added) and achieved 52% COD removal. The ...

Optimization of the thermophilic anaerobic co-digestion of pig manure, agriculture waste and inorganic additive through specific methanogenic activity
The anaerobic co-digestion of three wastes (manure, rice straw and clay residue, an inorganic additive) at different concentration levels and their interactive effects on methanogenic activity were investigated in this work at thermophilic conditions in order to enhance hydrolytic activity and methane production. A central composite design and the response surface methodology were applied for ...

SAS CMV Biogas Agricultural Methanisation, France - Case Study
In September 2015, 4 farms located in the Southern High Marned came together to operate a collective agricultural methanisation unit in Chalancey. Together, they combined to create the company SAS CMV Biogas. Nicolas LORIMIER and its associates then successfully inaugurated their first agricultural methanisation unit, recovering more than 15,940 tonnes of waste (livestock effluents) per year. To ...

Project aims to produce fertilizer from wastes
With the highest cattle density in northeastern Wisconsin and urban sprawl sprawling, Brown County has accelerated its investigation into how to handle growing amounts of dairy manure and industrial wastes spread on a diminishing land base.Applying waste on limited crop acreage has led to groundwater contamination issues and pollution problems of lower Green Bay.The solution lies in a value-added ...

Unlocking the potential of poultry manure
The poultry industry is one of the largest and fastest-growing agro-based industries in the world. At the same time, the growth brings along a number of environmental problems. One of the major environmental problems is the accumulation of large amounts of wastes, e.g. manure. In order to mitigate these problems new economically sustainable technologies are needed. Manure has often been referred ...
