Determination of Biogas Potential of Agricultural Residue from Agricultural Product Having High Cultivation Rate in Turkey

Abstract

Biogas production from biodegradable residues, provide environmental solution for waste management, beside energy recovery. In this article, energy potential of agricultural residue, having high cultivation and energy capacity was estimated based on the data of Turkish Statistical Institute. Agricultural land constitutes 30.40% of Turkey's whole lands. Cereals etc. are cultivated (66.44%) in large part of agricultural land. 15.81% of land is left as fallow land, while 14.30% of land is used for fruit, beverage and spices (herbs), 3.40% for vegetables, 0.02% for ornamental plant. Wheat is cultivated in 76990818 decare, barley in 24396791 decare, corn in 11253140 decare, sunflower in 7796217 decare and cotton in 5018534 decare as reported by TSI 2017. Calculated total biogas from agricultural residue is 240673168 m3/year in Turkey. Biogas energy equivalent was determined as 5463.19 TJ/year (130460.98 TEP/year). In this study, the province where energy consumption can be met at highest rate was determined as Şanlıurfa (21,16%). This phenomeon can be explained by low electricity demand of Şanlıurfa. Following Şanlıurfa, the rates of providing electricity consumption are Konya (16.86%), Adana (13.48%), Tekirdağ (11.24%) and İzmir (3.14%), respectively. Compensation percent of energy demand is considered as a very important criteria choosing place for biogas plant. © 2022, TUBITAK. All rights reserved.
