Energy and water management in the brewery – Part 1
All over the world, manufacturers are under increasing pressure to manage natural resources in a responsible manner. This applies also to the brewing industry. Since most processes in a brewery are carried out batch-wise, energy and water recovery and reuse in a brewery is complicated though this is becoming more widespread now. In this first part of the publication, the brewhouse and cellar processes are mapped with the aim of calculating real brewery requirements for heating, cooling and fresh water usage in each step of the process. This flow sheet can then be optimised to lower overall water and energy consumption.
