Background: Chrome shavings, a bioactive material, are generated from tannery as waste material. These chrome shavings can be used for the preparation of many value-added products.

Objective: One such attempt is made to use these chrome shaving wastes as a composite biobattery to produce DC voltage, an alternative green energy source and cleaner technology.

Methods: Chrome shavings were hydrolyzed to make collagen paste and mixed with the ferrous nanoparticles of Moringa oleifera leaves and carbon nanoparticles of onion peels to form electrolyte paste as the base. Then, the electrolyte base was added to the aluminum paste and conducting gel, and mixed well to form a composite material for bio-battery.

Results: The composite material of bio-battery has been characterized using Scanning Electron Microscopy (SEM), Fourier-Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC) and Thermo Gravimetric Analysis (TGA). Series and parallel circuit testing were done using copper and zinc electrodes or carbon and zinc electrodes as the battery terminals in the electrolyte paste. The surface area of these electrodes needed standardization from bench to pilot scale. The power generated, for an AA battery size, using a single bio-battery cell produced a DC voltage of 1.5 V; current of 900 mA. Circuit testing on 1 ml of 80 well-cells connected in series produced DC output of 18 V and 1100 mA, whereas 48 V and 1500 mA were obtained from a series-parallel connection.

Conclusion: The glass transition temperature (Tg) of electrolyte of the bio-battery at 53°C indicated that at this temperature, all the substances present in the bio-battery were well spread and consistently contributed to the electrolyte activity where Fe-C-nano-particles were able to form strong chemical bonds on the flanking hydroxyl group sites of the collagen leading to reduced mobility of polymers and increased Tg. The results instigate promising trends for commercial exploitation of this composite for bio-battery production.
