Since 2008, Viegand Maagøe has helped Arla Foods AMBA to map its manufacturing plants and to obtain subsidies for energy-efficient solutions. Some of this work focuses on energy optimization in production processes and establishing new utility systems.

Client: Arla Foods Amba

The task
Viegand Maagøe carried out energy audits at 15 of Arla’s manufacturing plants in Denmark and Sweden to identify possible ways to save energy in processing plants and to outline detailed energy balances in various operating conditions.

How we carried out the task
Energy audits included:

  • mapping the consumption of steam, electricity and water;
  • scrutinizing processes and utility systems to establish energy balances;
  • outlining composite curves and pinch analyses;
  • setting up metering programmes to determine the actual operations;
  • interviewing operators and the people responsible for processes in various focus areas;
  • challenging the process parameters and operational requirements of users;
  • holding workshops on energy management in accordance with the principles of ISO 50001; and
  • documenting the savings projects to obtain subsidies.

Energy audits establish the framework for:

  • improving the efficiency of processing equipment in the manufacturing plant, with the primary focus on recovering heat internally in the processes, such as in spray drying and regeneratives in pasteurization; and
  • establishing the framework for large heat pump systems in the energy supply system at five manufacturing plants based on hybrid heat pumps combining process cooling and process heating in a unitary circuit with both hot and cold storage.

The result
Our assistance provides a useful database for planning comprehensive investment projects that will be implemented realized in the coming years at manufacturing plants in Denmark as part of Arla Foods’ structural plan.
