1. In Finland, HKScan renewed its commitment to the food industry’s Energy Efficiency Agreements (EEA) for the period 2017–2025. By being part of the Energy Efficiency Agreements in its field, HKScan takes responsibility for meeting the national energy efficiency target. Energy Efficiency Agreements are part of the national energy and climate strategy, and are an important way of promoting energy efficiency voluntarily, without the need for legislation.
2. At HKScan’s production facilities in Finland, a number of efforts have been made towards meeting the energy efficiency targets. The energy reviews in Forssa and Vantaa brought to light several areas for improvement. Several investments were made in 2017 to improve energy efficiency, such as investments in new equipment and energy recovery systems. Design and testing of new and more efficient technologies was initiated in partnership with partners. Efforts were also made at the production plants to find new opportunities for improvement by analysing everyday work practices. In 2017, HKScan opened a new production facility for poultry meat in Rauma, and the winding down of operations at the Eura production facility began. The Eura production facility will operate in parallel with the Rauma facility until April 2018 at the earliest. The new production plant in Rauma is highly energy-efficient, owing to the new equipment and the use of the best available technology.
3. All production plants in Sweden are certified according to the ISO 50001 standard. Several measures were taken in 2017 to improve energy efficiency in the facilities in Sweden, for example by overhauling ventilation systems and installing LED lights. The energy consumption rate at the production plant in Linköping fell by about 500 MWh over the course of 2017, continuing a trend that has been ongoing for the past five years.
4. At the Skara production plant in Sweden, the energy-efficiency review conducted in accordance with the ISO 50001 standard gave rise to six energy efficiency projects. The first of these was completed in autumn 2017, and the second will be completed in spring 2018.
5. An energy efficiency review was carried out at the Rakvere production plant in Estonia, and this has led to several proposals for saving energy. In 2016, energy efficiency was improved at the Rakvere plant by installing a heat pump to recover and store energy from the wastewater treatment process. The benefits of this investment became evident in 2017, when the consumption of natural gas for that year was 10 per cent lower than in the previous year. In addition, a new frequency converter was installed on the 500 kW ammonia compressor, which resulted in a five per cent reduction in total energy consumption at the Rakvere plant. Reverse osmosis equipment was installed in the water boiler, bringing a reduction of three per cent in natural gas consumption. At the Tabasalu facility, a reduction of six per cent in natural gas consumption was achieved through the adoption of air compressors that use recovered heat to heat water.
6. In Denmark HKScan is now using more energy-efficient air compressors and ventilation units.
7. In Poland and Latvia, energy consumption in 2017 was reduced by switching to LED lighting. In Poland, energy efficiency was also improved by cleaning the waste heat recovery exchangers in the hot-smoking tunnels more regularly.
8. Energy consumption could be further reduced in several production plants by testing compressed air and vacuum systems for leakages.
9. In Finland, the Forssa production plant achieved a notable reduction in energy consumption when the usage times of a number of large vacuum pumps were changed on the initiative of a maintenance worker.
10. At the Rakvere pork farm, energy efficiency is improved by adopting a completely new ventilation system. This will come into operation in 2020. HKScan is investing is a cooling system for sludge, with the aim of using the heat recovered by this system for heating. In addition, air quality is improved by removing ammonia from it. The investments are expected to create energy savings of 70 per cent from 2011 levels.
