Our methodology offers production of sustainable nanomaterial, nanocellulose and a 2nd generation biofuel, dimethyl furan from agricultural wastes—rice-straw and green-coconut shells. Along the value chain of products derived from agricultural waste, nanocellulose, and dimethyl furan are very demanding. Nanocellulose finds vivid applications in CO2 capture, drilling fluid, radiative cooler, pharmaceuticals, electronic devices, membranes, and others. Whereas Dimethyl Furan is potential a biofuel that can be blended with gasoline. Hence, it will enforce a circular synergy between lignocellulosic biomass and petroleum industry for achieving Net Zero emissions and bring down oil import bills. Developed process chemistry involves simultaneous production of these carbon-neutral products. It has been transferred to Chennai Petroleum Corporation Limited (CPCL) for process optimization at 100 KPD pilot plant. This joint-venture has the enough potential to address multiple issues at one time- removing the root-cause of farmer-distress through opening streams of their income, employment generation for skilled persons, strengthening the Startup India programme of our country, and getting rid of issues with crop residue burning.
