Subscale mapping of animal waste-based biogas potential and its equivalent energies using GIS: Canakkale, Türkiye

Abstract

The study presents the first attempt of determination and mapping of recent biogas potentials (BP) at different scales from province to village level in Çanakkale using Geographic Information Systems (GIS). The BP of different scales was calculated based on animal waste amounts from bovine, ovine and poultry farming. The study area covers the ten districts of Çanakkale province with the exception of Imbros and Tenedos Islands. The inventory records of different animal types were obtained from of Republic of Turkey Ministry of Agriculture and Forestry Çanakkale Directorate of Provincial Agriculture and Forestry. GIS procedures are conducted in ArcGIS (10.3) software. Findings revealed that the annual biogas production potential of the whole province is almost 6.4×107 m3. Biga district seemed to include 39 % of overall BP whereas Eceabat district presented a slight percentage of the potential production with the value of approximately 1 %. Moreover, the highest and lowest subscale-level potentials have found in Yukarıdemirci (Biga) and Bahçedere (Ayvacık), with approximately 154×104 m3 and 137 m3 BP, respectively. The overall BP of the province have concluded to be promising, and present study believed to serve as a baseline for future studies related to determination of new biogas plant suitable lands.
