From waste water to soil improvement

Published 16 July 2012 | By Alectia

Türk Tuborg had problems with their waste water system and contacted ALECTIA. The brewery is located in Izmir on the Aegean Sea and produces approximately 1.8 million hl of beer per year. The brewery includes a malt house, which processes approximately 300 tonnes of barley per day. The waste water from the brewery and the malt house is collected and cleaned in the brewery’s waste water treatment plant.

case study

ALECTIA has provided consultancy for Türk Tuborg regarding the handling and reuse of waste water on the basis of our expertise in waste water management combined with our experiences in brewery processes. This has generated significant savings for Türk Tuborg, and the following goals have been achieved:

  • Annual savings of approximately EUR 500,000 for sludge removal (deposits) due to a reduction of almost 80% of the amount of sludge.
  • Annual energy savings of 1 million kWh, corresponding to approximately EUR 70,000-80,000.
  • A one-time saving of EUR 2 million, as investing in separate sludge stabilisation was proved unnecessary.

Our consultancy services covered both technical as well as legal aspects from a national and international point of view. In this connection, we assisted Türk Tuborg to document the successful operation of the waster water treatment plant with the authorities and receive the final approval for the present plant configuration.

The ultimate goal was to use the waste water sludge for agricultural fertilizers, which is the most economical and environment-friendly solution. This form of recycling is expected to provide annual savings of approximately EUR 100,000-200,000.
