Introduction of composted digestates in agriculture
Municipal organic waste is increasingly recycled by aerobic composting or anaerobic digestion procedures. In 1997, 230 000 Mg organic waste were composted and used for agriculture in the region of Cologne, which is an increase by 70% compared to 1994 (Anonymous, 1999). Therefore, the effects of compost on the soil and the plants require studies on:- its nutrient contents to contribute to 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 ...
