Preliminary study on withered flowers as substrate for biogas production has been carried out using anaerobic digestion. Three experimental sets have been conducted by varying the substrate to inoculum concentration such as 2: 1, 1: 1 and 1: 2. Digester has been designed with an outer and inner cylinder of 500 and 300 liters capacity respectively. Substrate concentrations were also varied as 5, 7, 9, 10, 11 and 12% to analyze the amount o biogas produced per kg of substrate. Results showed that 7% of substrate concentration to be optimum for biogas production. The yield of biogas was also found to be higher with less digestion time period. Flowers which are available in plenty which was thrown in garbage after a few days can be used efficiently as a source for energy production. This concept can also be seen as waste to energy to enhance the sustainability of the environment.
