Water scarcity has emerged as one of the potentially pressing global issue. India is facing its worst ever water crisis with more than half of the locations under severe water stress. The situation is too alarming which necessitates the need of new technological interventions to address this issue on priority. Atmospheric Water Generation (AWG) generating water from the humidity present in air could be viewed as a futurisitic solution to water scarcity. Currently available AWG systems are still in nascent stage and not yet emerged as a feasible solution affordable to all communities. The current research work aims to develop an off-grid hybrid AWG system suitable to rural communities as well, and support the 'Har Ghar Jal' scheme of Jal Jeevan Mission, Government of India.

Production of highly porous biomass derived activated carbon for emerging applications
Synthesis route for biomass derived activated carbon
Crop residue management in India has been problematic for decades due to the in-situ burning of crop-residues causing climate change, health issues, and soil degradation. The present work focuses on the synthesization and characterization of highly porous activated carbon (AC) using sugarcane bagasse (SB) and rice straw (RS). The effect of carbonization temperature on the biochar yield and carbon content is studied to identify the best biochar product before activation. The synthesized ACs exhibit higher BET surface area with larger distribution of micro- and meso- pores than commercial ACs. Furthermore, based on laboratory scale cost analysis and detailed characterizations, the synthesized ACs could be viewed as a sustainable alternative to commercial ACs for various applications.
