< span style="font-size:14px">Present study deals with the situation and phenomenon of biogas plants being under working and non –working conditions in Chhattisgarh state, India. The characteristic of working and non –working biogas plants is a continuous birth and death like process which is dynamic in nature. The non –working plants are rare in large domain of biogas plants established. The dynamic characteristics of working and non –working biogas plants follow some rule of path or probability distribution. Therefore, an attempt has been made in the study to estimate loss of biogas energy because of non –working biogas plants and unused dung in the given domain of Chhattisgarh state. The data of working and non –working biogas plants was collected by using appropriate sampling technique and biogas loss is estimated. Biogas loss due to non –working biogas plants was estimated to be 10491 m3/ day. Biogas loss due to unused dung was estimated as 2570835 m3 /day. Rank correlation coefficient between dung availability and established biogas plants is found to be 0.05057. It indicates that the dung availability is not associated with establishment of biogas plants but some other reason such as environmental awareness, education and technological knowhow are responsible for establishment of biogas plants.
