Sustainable cost savings at dairy factory

ERIKS can measure direct and indirect costs of solutions

The ERIKS Group firmly believes that sustainability should not come at a cost. By applying a Total Cost of Ownership approach (TCO), ERIKS can measure direct and indirect costs of solutions. This means customers often see not only lower emissions, but also a lower energy bill - as did a large dairy manufacturer in the Netherlands.

Challenge 1

In the customer's dairy plant, pipes are cleaned with steam. A key component of this system are steam traps, which keep steam in the system whilst removing the condensate. However, leaking steam traps waste a lot of energy.

Solution

ERIKS measured the leakage in several plants, and based on these measurements recommended replacing traps which were leaking. The result was significant annual savings of carbon dioxide emissions, energy – and money.

Challenge 2

Sustainable cost savings can also be achieved with energy efficient electric motors. In another of the customer’s plants, a 450 kW electric motor powering an extractor had broken down and needed repair. The cost of repair was just 10% of the purchase cost of a new motor.

Solution

ERIKS’ TCO calculations revealed the payback period for a new, more efficient motor. Based on these figures, the company bought a new motor and recouped the cost within fourteen months.

Challenge 3

Lastly, we surveyed the company’s pneumatic systems in its packaging lines. The air in the systems is pressurized by a compressor driven by an electric motor. If air is leaking out, the electric motor uses far more energy. Our investigation revealed that, in one plant alone, 433,000 cubic meters of air were lost to leaks every year.

Solution

Our advice was to rectify the leaks by replacing components and refitting the pipe system. As a result of this work, energy consumption and costs fell significantly – proving once again that sustainability can save more than energy.
