Abstract

Biogas, which is the end product of anaerobic digestion of biowastes can successfully increase the cooking fuels in the educational institutions where the bio resources are available in plenty. This paper assesses the biogas potential and economic analysis from the biowaste generated in an educational institution situated in the southern part of Tamil Nadu, India. Theoretical study using a matlab toolbox named Anaerobic Digestion Model 1 (ADM1) was estimated and validated with experimental analysis using anaerobic digesters for different volumes. This has been conducted with biowastes generated in the institution for predicting the quality of biogas. Based on the obtained biogas production data, the techno economic evaluation was performed replacing Liquefied Petroleum Gas (LPG) which is used for cooking in the institution. The study shows that the biogas production during academic and nonacademic periods is between 58% and 52.28%. The result reveals that the biogas production is economically viable with a payback period (PBP) of 1.65 to 0.61 years for cow dung (CD) and 1.47 to 0.38 years for kitchen waste (KW) based biogas plants respectively. The sensitivity analysis proves that the maximum influence of uncertainty in input parameters on the cost of cow dung, income from biowaste and the cost of digester influence the output parameters of the payback period for cow dung and kitchen waste.
