Abstract:
Biomass from crop residue remains an underutilized and inexpensive energy resource around the world.Inadequate supply chain management forces farmers to resort tofield burning of crop residue, resultingin environmental, health, and economic issues. In this study, we conceptualize a novel approach forbiomass utilization which jointly addresses the common and often concurrent issues of energy, envi-ronment, and water. We propose to use the thermal energy from the combustion of the producer gasobtained from biomass gasification to power an off-the-grid refrigeration system which can condensemoisture from air. We conduct a detailed thermodynamic analysis of vapor-adsorption cycle-based at-mospheric water harvesting (AWH) system to develop an integrated modeling framework. We use theambient weather data to report that the biomass-powered AWH can condense 800e1200 L of water per1000 kg of biomass. Based on the local population and biomass availability, this can meet up to 10e12% ofthe potable water requirements in certain states of India. We also discuss the immediate challengesunderlying this waste-to-value concept. Finally, we discuss that the proposition to jointly address energy,water, and the environment issues may motivate key paradigm shifts in policies required for practicalimplementation of this technology.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
