Valorisation of organic wastes in renewable energy production has attracted a global attention in order to achieve a sustainable industrial growth. Anaerobic digestion (AD) is considered to be one of the most environmentally friendly waste management technology and also fulfils the necessity of a sustainable fuel generation. It has much less energy demand than other technologies like gasification or pyrolysis due to its low operation temperature. Whiskey distillery wastewater, pot ale, is classified as a high strength waste due its high organic content hence rendering it a suitable substrate for anaerobic digestion. Despite its waste-to-energy conversion potential, pot ale contains high lignin fraction which makes it resistant to biodegradation. Therefore introducing a pre-treatment step is required to enhance the biogas production and organic matter degradation. In this study anaerobic digestion of pot ale was assessed at lab scale batch mode reactor after implementation of 1 M NaOH and microwave pre-treatments at varying power settings. Response Surface Methodology was adopted for process modelling and optimisation in which inoculum substrate ratio, initial digestion pH and microwave power were investigated at three different levels. In addition, the mineral quality of the pot ale digestate has been analysed for its agricultural use.

为了实现可持续的工业增长，可再生能源生产中有机废物的价值吸引已引起全球关注。厌氧消化（AD）被认为是最环保的废物管理技术之一，也满足了可持续燃料生产的需求。由于其较低的工作温度，与其他技术如气化或热解相比，它的能源需求要少得多。威士忌酒废水，大罐啤酒，由于其有机物含量高而被归类为高强度废物，因此使其成为厌氧消化的合适底物。尽管淡啤酒具有废物转化为能源的潜力，但其含有较高的木质素含量，因此具有抗生物降解性。因此，需要引入预处理步骤来增强沼气的产生和有机物的降解。在这项研究中，在不同功率设置下实施1 M NaOH和微波预处理后，在实验室规模的分批模式反应器中评估了罐装啤酒的厌氧消化。采用响应面方法进行工艺建模和优化，在三个不同的水平上研究了接种底物比率，初始消化pH和微波功率。此外，还分析了大锅菜消化物的矿物质质量，将其用于农业。采用响应面方法进行工艺建模和优化，在三个不同的水平上研究了接种底物比率，初始消化pH和微波功率。此外，还分析了大锅菜消化物的矿物质质量，将其用于农业。采用响应面方法进行工艺建模和优化，在三个不同的水平上研究了接种底物比率，初始消化pH和微波功率。此外，还分析了大锅菜消化物的矿物质质量，将其用于农业。
