The goal of the following research is to demonstrate that Carlton & United Breweries (CUB) reduced energy and water consumption will not only protect their environment, but also earn and save them extra income. Brewing used to require about 25 litres of water per litre of beer, nowadays it requires only 4 to 5 litres , on the other hand, compressed air accounts about 10 % of electricity consumption in the industry . CUB needs to use cutting edge technologies, more preventive maintenance programs and very simple ways in which the procedure can become cleaner in order to reach and overcome these requirements. And lets not forget that every litre of water and watt of energy saved will be reflected as a profit. Water Issue CUB has taken the water issue in consideration, reducing its consumption by 7 - 9 %, only by installing a recycling system which is capable of distributing re-used water for the cooling towers of the engine room, boiler house, floor wash-down and pasteurization . However, there is a lot that can be done in order to reduce even more this percentage; cisterns on the roof collect rainwater that can be used for the toilets and landscape irrigation, saving 3. 9 million litres of potable water a year , and also, can be purified and used as the re-used water if necessary .
Cascade Brewery, also from Australia, is saving an average of 5, 812 KL per month , some of their main water reduction actions are: replacement of heat exchange equipment with more efficient units, steam condensate return to the boilers, The installation of a 32 KL tank at to collect water from the carbon dioxide and air compressors for use as boiler feed water, among others . Compressed Air Issue Not much has been done in order to make a significative reduction in the compressed air issue. Actually, it has reduced 1 %, only by applying air knives instead of compressed air in order to dry the bottles before labelling and a leak identification program. There is wide range of possibilities CUB could work on in order to reduce its compressed air consumption, which its translated into less energy consumption from the air compressors and blowers.
Switch to state of the art air compressors, these can really mean a huge difference regarding energy consumption . Variable Speed compressors (VS), can match the air demand by adjusting the motors RPMs and energy consumption, however, VS are most efficient at low to mid capacity ranges (20 - 60 % full load), and are designed only to intermittent operation at 100 % capacity . To cover the mid to upper capacity ranges, CUB could relay in turn valve compressors, which find their most efficient range from 60 % to 100 % of their capacity . By using these technologies, the plant itself will determine, by the air demand, which machine to use. Machines are complementary, not competitive, these two compressors, working together can handle the entire range effectively . Even though air knives reduced compressed air consumption, CUB could try using a blower instead, which works more economical, and they dont affect air compressors performance by lowering their flow and pressure .
CUB can reduce even more its air compressors energy costs by 1 % for every 3 degrees reduction in the air compressors inlet temperature . Wrap-Up - There is a lot that can be done to reduce water and energy consumption. - Taking care of the environment can give CUB an extra income. - Reduce water consumption with: o Rainwater o Recycling o Reusing - Reduce compressed air consumption by: o Turn Valve and Variable Speed Compressors. o Use more economical ways of drying, like blowers. o Reduce the air compressors inlet temperature. Effective measures have been taken by CUB in order to reduce energy and water consumption; however there is a wide range of opportunities to gain extra profits from.
The faster these considerations take place, the faster CUB will start helping the environment and start saving on energy and water bills. Also, long term planning will help reduce resources consumption even more, which will translate in further savings, for the environment and for the company.
