The study concludes that it would be advisable to feed the liquid co-products to an anaerobic digester to produce methane. A power generator can use this fuel to meet the electricity demand of the distillery, the surplus could be fed to the grid. Exhaust gases from the generator can be utilised by a waste heat boiler to offset the steam requirements of the stills. This would result in an annual economic benefit of £178,450 and a payback period of 5 years.

The Sankey diagram shows electric energy in MWh, co-products in tons per year, and biomass in cubic metres. Hence, these flows must not be compared to each other. I am unsure about the red arrow from the steam boiler to the distillery, which is labelled ’18,841 MWh’ as it doesn’t seem to be to scale with the other energy flows.

Anyways. I like this one. Here’s tae us, wha’s like us? Damn few, and they’re a’ deid.

I am reproducing one below, that pretty much has the same purpose as the one I showed in a previous post for the U.S.

Check for yourself the differences…
