Solid waste disposal is increasingly becoming a huge challenge to tanners due to paucity of landfill sites and strict environmental legislations worldwide. Hence, finding a holistic solution to the tannery solid waste disposal problem is a challenge for researchers. Protein based solid wastes acquire much attention due to its high value. In this work, proteinous matter recovered from chrome shaving through chemical process was feed to the anaerobic digester to generate biogas. Two different modes of alkaline chromed shaving dust hydrolysis i.e. using lime and KOH followed by neutralization with HCl and H3PO4 subsequently. The Full scale investigations conducted to evaluate the performance of anaerobic digestion of collagen hydrolysate. The feed and overflow of both digesters were monitored for various parameters such as total solids %, ash content %, volatile fatty acids and chemical oxygen demand (COD). COD reduction efficiency 34-46 % and 45-54% was observed in lime-HCl and KOH-H3PO4 digesters respectively. Gas generation is increased 30% in KOH-H3PO4 digester as compared to Lime-HCl and CO2 % in KOH-H3PO4 digester was in the range of 19-20% as compared to Lime-HCl were it was 30-40%. Hence, it shows that CO2 produced by the acidogens is effectively utilized by the methanogens in producing methane gas and potassium and phosphates are the macronutrients to the microorganisms.
