Case Study on Production of Bio Gas from Press Mud

Abstract:India has a key position in the worldwide sugar economy, emerging as the foremost sugar producer since 2021-22,surpassing Brazil in production. Additionally, the status of the second-largest sugar exporter globally is held by India. Overthe past five years, the sugar industry has been strengthened by the expansion of the ethanol biofuel sector, contributing tothe improved financial standing of sugar mills. Press mud, often known as filter cake or press cake, is acknowledged as avaluable resource for green energy production. Press mud is a residual byproduct of the sugar industry. Additional revenuecan be generated for Indian sugar mills by utilizing this byproduct as a feedstock for biogas production through anaerobicdigestion and subsequent purification to create compressed biogas (CBG). During the 2022-23 timeframe, among the 531operational sugar mills in India, 330 were privately owned, 190 were cooperative, and 11 were public. The fiscal year 2022-23recorded India’s sugar production at 32.74 million tonnes, along with approximately 11.4 million tonnes of press mud.Regarding regional production, Uttar Pradesh and Maharashtra contribute to approximately 65 percent of the totalsugarcane cultivation area, being the primary sugarcane-growing states. The total sugarcane production in India reachedabout 495 million tonnes in 2022-23, with key contributions from Uttar Pradesh (225.2 million tonnes), Maharashtra (123.9million tonnes), Karnataka (62.5 million tonnes), Tamil Nadu (16.9 million tonnes), and Bihar (12.1 million tonnes).
