Sustainable brewing and distilling - energy

Distilling - energy


Electricity costs


Costs of pumping water depend on water volume and pressure drop supplied


Audit Water usage


Do you have cold radiators in a tank room?


Compressed air may take up as much as 10% of a distillery's electricity usage.


Audit regularly for leaks


Ultrasonic air leak detection is available


Consider air flow meters on large compressed air users



Case study: Grolsch optimise ventilation and lighting

SABMiller's Grolsch brewery in The Netherlands recognised that savings were possible in their electricity use for ventilation and lighting. These are the highest uses of energy outside of the brewing process at the brewery. By changing the schedule of ventilation and lighting to run only when brewing operations were carried out, rather than during fixed times during the day, massive savings could be made. This has been implemented since January 2009 and as a result, the brewery has reported saving more than 100,000 kWh a month without significant capital investment.

Case study: Improving plant refrigeration system

A new refrigeration design using half the energy compared to the previous one was installed in Bank's brewery in the UK. The new system used reciprocating ammonia compressors, air cooled condensers and calcium chloride brine for secondary heat transfer. Variable speed drives ensured minimal energy use at all times.

Case study: Red Stripe saving on electricity costs with lighting and variable speed drives

1). Installation of energy saving lighting and motion sensors in offices estimated savings of J$ 22 000 000 (£ 160 000) per year. 2). Installation of variable speed drives on pumps at the chillwater plant, filtration and deaerated liqour plant resulting in savings of J$ 16 000 000 ((£ 138 000) per year.
