Abstract
The study was undertaken to investigate the generation of biogas from medicinal plant processing waste. In order to know biogas production and methane content, medicinal
plant processing waste samples were kept anaerobically for two-months in lab-condition.
Carica papaya leaf and Azadirachta indica yields about 11320 ml and 10610 ml of biogas
with 62.98 and 74.12 per cent of methane content which were observed highest. Garcinia gummi-gutta and Cinnamomum verum were the lowest biogas yielders. An investigation was conducted to know the performance evaluation of 500 m3 biogas power plant located in Prakruti Products Pvt. Ltd, Ankola. An average biogas Generated about 560.37 m3 per day in the temperature range between 20 to 30°C. CO2 and H2S was removed by water scrubbing method and methane content was measured. It was found that, the methane content after purification was increased up to 22 per cent than before purification. The collected pressurized biogas from the digester was transferred to the generator and produces the electricity of about 645.24 kWh and utilized for various operations in the plant. As per the data assessed from the biogas power plant it summarised that, biogas power plant has economically viable and environmentally sustainable. It was concluded that, instead of dumping or burning of medicinal plant processing waste and causing different types of pollution in the environment, this is the best method of utilization of waste to convert energy in a good manner.
