Data for: Cotreatment-assisted anaerobic digestion of poultry manure and switchgrass, United States, 2021-2022

Author(s): Thomas McVey, Daniel Ciolkosz

Abstract:

This dataset documents experimental results from a study of cotreatment-assisted anaerobic digestion of poultry manure-switchgrass mixtures conducted at laboratory scale. The research evaluated how feedstock composition, milling-based cotreatment, and retention time influence biogas production, methane yield, solids destruction, alkalinity, and nitrogen dynamics in anaerobic digesters. Semi-continuous stirred tank reactors (S-CSTRs) were operated under mesophilic conditions using two manure-to-switchgrass ratios, followed by batch digestion experiments in OxiTop® reactors using milled and unmilled effluent material at multiple post-treatment retention times. Measurements include biogas volume and composition, methane production normalized to volatile solids fed, total and volatile solids destruction, pH, alkalinity, total ammonia nitrogen, free ammonia nitrogen, and supporting calibration data. Together, these data support assessment of cotreatment as a strategy for modestly enhancing biogas production from nitrogen-rich, lignocellulosic poultry litter and provide an empirical basis for process modeling and technoeconomic evaluation of anaerobic digestion systems handling poultry litter feedstocks.
