Design of a pre-treatment integrated anaerobic digestion treatment facility for decarbonising whiskey industry: A circular economy perspective.

ABSTRACT: This paper outlines the sustainable management of the whiskey distillery by-products, known as draff and pot ale, through anaerobic digestion (AD). The substrates were pre-treated using 0.6M NaOH and high shear homogenizer for 24 h. Substrate pre-treatment helped improve the digestabilility of lignocellulosic materials towards AD. In addition, the complex cellulose, hemicellulose and lignin contents are disintegrated. A continuous stirred tank reactor with a volume of 1766 m³ and organic loading rate of 4.04 kg COD/m³/day operating under mesophilic conditions for 30 days was designed to facilitate the complete digestion of the substrates. Compared with the conventional digesters, the proposed novel pre-treatment method achieved a 20% increase in methane yield. The ene
