Recoverable resources from pot ale & spent wash from Scotch Whisky production

Utilisation and valorisation of distillery whisky waste streams via biomass electrolysis: electrosynthesis of hydrogen

“…29 Overall, it can be concluded that the compositional parameters of draff, pot ale and spent lees examined in this research are typical of those expected in the wider whisky distillation sector in Scotland. 25,[29][30][31] Thermal digestion of whisky co-products and assessment of catalyst reduction processes that the catalyst exhibits. Fig.…”

From brew to clean fuel: harnessing distillery wastewater for electrolysis H2 generation using nano scale nickle selenide water oxidation catalysts

“…By implementing systems for recovery, treatment, and reuse, a signicant portion of the wastewater can be repurposed for activities, such as boiler feed water and cooling processes, leading to reduced disposal costs. 14,15 Depending on the composition of the brewery wastewater, the presence of sugars, alcohol, and soluble starch allow the wastewater to be utilised for biogas production. However, there is still considerable potential for utilising this wastewater in the electrolysis process due to its high biomass content.…”
