Assessment of Biogas Production Potential of Livestock Wastes in Tokat Province by Geographic Information Systems (GIS) Technologies

The present study was conducted to determine the biogas production potential of livestock wastes of tokat province with intensive livestock facilities by the aid of gis technologies, to identify possible use of these wastes in energy production and to determine the contributions provided to economy. biogas production potential of tokat province was calculated as 301 434 m3/day with an energy equivalent of 502 390 kwh/day. since livestock facilities are common in the region and it is easy to collect livestock waste, livestock wastes among the animal wastes were taken into consideration and pilot central biogas facilities were designed for 250, 500 and 1 000 animal capacities. floor plans, cross-sections and side wives were all drawn in autocad and dimensioning, energy analyses and costing were performed for those facilities. arcmap software was used in analyses to determine the locations, numbers and capacities of biogas facilities based on animal intensities and distances between rural settlements. analyses revealed that 228 biogas facilities could be constructed for 250 animal, 171 facilities for 500 animal and 131 facilities for 1000 animal.
