Pot-ale is the principal effluent co-product of the whisky industry and is produced in copious quantities with between 8.5 -10 litres of pot-ale being created for each litre of manufactured whisky. Treatment technologies have largely been restricted to applying heat to pot-ale to create a molasses type syrup or energy extraction via AD to create heat and electricity. A Zero Waste Scotland report suggested that up to 2 billion litres of pot-ale could be available for bio-refining.Laboratory research has demonstrated that a secondary fermentation process is capable of producing a valuable class of compounds known as 'volatile fatty acids'(VFAs). Chief amongst these is hexanoic acid, a C6 short-chain acid which has numerous uses across a wide range of industries, including food, pharma, cosmetics and plastics. World supplies of hexanoic acid are largely derived from palm oil which is predominantly grown in South-East Asia. The carbon footprint for world hexanoic acid production is estimated to be in excess of 37M tonnes/CO2eq. per annum.Work undertaken with the Bio-Renewables Development Centre (BDC) is currently in the process of identifying hexanoic acid producing bacteria from samples of AD digestate. The task is now to extend this research and undertake a feasibility study to determine how to best extract and store VFAs from the fermentation mixture. The results will then establish the cost profile for this element within the overall process. This is an important step in determining process optimisation and informing the financial decision to commit substantial funds to full sized plant.

Pot-ale是威士忌工业的主要废水副产品，是大量生产的，每升每升生产威士忌都会创建8.5 -10升的Pot-ale。治疗技术在很大程度上仅限于将热量施加到锅奶中，以通过AD形成糖蜜型糖浆或能量提取以产生热量和电力。零废物苏格兰的一份报告表明，可用于生物替代的多达20亿升的盆栽。实验室研究表明，次级发酵过程能够生产出称为“挥发性脂肪酸”的有价值的化合物（VFAS）（VFAS）。其中主要是C6短链酸己酸，它在包括食品，制药，化妆品和塑料在内的各种行业中都有多种用途。六酸的世界供应主要来自东南亚主要种植的棕榈油。据估计，世界己酸的碳足迹估计超过37m吨/二氧化碳。目前，使用Bio-Renewables开发中心（BDC）进行的每年进行的工作正在鉴定从AD Digestate样品中鉴定出产生己酸的细菌。现在的任务是扩展这项研究并进行可行性研究，以确定如何最好地从发酵混合物中提取和存储VFA。然后，结果将在整个过程中建立此元素的成本概况。这是确定流程优化并告知财务决定将大量资金投入到全尺寸工厂的重要步骤。
