The food industry consumes vast amounts of energy, water, and heat due to demanding technological processes such as pasteurization, cooling, and steam generation. Reducing these operational costs not only yields measurable savings but also positively impacts the environment by lowering pollutant emissions.
Energy Audit as a Starting Point
The foundation for energy-saving initiatives is an energy audit. This process provides a detailed understanding of where and how much energy is consumed within an enterprise. Identifying key areas of energy loss enables the planning of changes that will most effectively improve the facility’s operations.
Modernizing Installations
Many companies achieve success by upgrading their production systems. For example, modernizing boilers or cooling systems can bring significant benefits. A noteworthy case is OSM Włoszczowa, where improvements in the steam boiler room and cooling systems reduced particulate emissions and increased energy efficiency by 20%.
Utilizing Renewable Energy
An increasing number of companies are adopting renewable energy sources. Technologies like biogas, biomass, or solar power not only lower carbon dioxide emissions but also reduce operating costs. At the Dairy Crest factory in the UK, a biomass combustion system was implemented, allowing 90% of steam production to come from renewable sources and reducing energy costs by 42%.
Cogeneration as a Comprehensive Solution
Cogeneration units enable the simultaneous production of electricity and heat using the same fuel. Nestle’s factory in Portugal implemented such a solution, reducing energy production costs and cutting CO2 emissions by 5,000 tons annually.
Optimizing Water Usage
Water is an essential element in food production, used in technological processes, cooling, and cleaning. Water and heat recovery systems help reduce water consumption and lower costs, representing another area where companies can achieve substantial savings.
Why Invest in Energy Efficiency
Improving energy efficiency is not only a way to reduce operating costs but also a means to enhance the reliability of technological processes and decrease pollutant emissions. In the long run, these investments benefit both businesses and the environment, making them a priority for industrial companies.
