Sugar industry is an agro-based industry which impart significant contribution in the socio-economic development of the nations to fulfil one of the necessities of human survival.
India’s sugar industry produces vast amounts of by-products such as molasses, press-mud, bagasse etc. To support the economic viability, predominant by-products of the sugar industry - molasses is utilized by distilleries and generate revenue from alcohol, where this process generates 10 -15 m3 distillery wastewater/m3 alcohol produced, and press-mud approximate 3-4% of the weight of the cane crushed [1]. Conversion of these by-products/ waste into valuable Biogas to Compressed Biogas (CBG) through bio-methanation and Fermented Organic manure (FOM) & Liquid Fermented Organic manure (LFOM) from press-mud digestate. Sugar and Distillery Industries can generate a significant additional income stream, improve waste management practices and contribute to a greener future. This not only stabilizes their financial health but also contributes to environmental sustainability.
This invention enables utilisation of indigenous greener fuel & potassic resource while addressing critical environmental concern to enhance the zero-waste economy for a sustainable future.
