Energy efficiency

HKScan’s active approach to ensuring efficient use of energy is aimed at reducing the company’s environmental footprint and improving cost-effectiveness over the long term. Improving energy efficiency is also an important part of our commitment to reducing greenhouse gas emissions.

The energy-efficiency project fell short of the target

In 2015, HKScan launched an energy-efficiency project with the aim to reduce energy consumption relative to net sales by 10 per cent over the period 2014–2017. Over the course of the energy-efficiency project, energy consumption in relation to net sales turned out to be -0,29 per cent. The reason for not reaching the target is due to the reduced sales during the period. Total energy consumption measured in GWh decreased by 3 per cent from 2014 to 2017. In 2016, total energy consumption fell by 5 per cent compared to 2014.

Although the energy efficiency target was not reached we have worked actively. In fact over the course of the project, energy efficiency was improved in production facilities through measures aimed at streamlining and rationalising operations. Total energy consumption decreased in HKScan’s operations in Sweden, Denmark and Estonia relative to the 2014 baseline. Total energy consumption in Finland increased, affected by some investments that have been made. In 2016, HKScan acquired the Forssa business operations of Pakastamo Oy, and the Rauma poultry production plant, opened in 2017, is operating concurrently with the Eura plant. Production in Rauma will replace the production operations at the Eura plant, which will be shut down in 2018.

A lot of valuable research and reporting have been accomplished and several production facilities developed detailed plans on the basis of this work in 2017. The implementation of the plans will continue in 2018, and the results will be visible over the coming years. These measures will also improve energy efficiency.

Energy reviews continued

HKScan continues to systematically carry out energy reviews to find targets for energy-saving measures, and to meet the European Union’s Energy Efficiency Directive. The reviews were carried out at HKScan’s production facilities in Sweden, Poland and Denmark during 2015 and 2016, and in the Baltic countries and Finland the process has been ongoing in 2017. HKScan’s production facilities in Sweden are also certified in accordance with the ISO 50001 standard. Both energy audits and certification processes have helped HKScan to identify several development areas. Development activities have resulted in improving energy efficiency, and further improvements will also be made through future investments.

One aim of projects to improve energy efficiency is to measure energy and water consumption at each specific production plant to identify new savings potential. Meters have been installed in the production plants to transmit the consumption data for energy and water use directly to an electronic system. The system was introduced in 2017. HKScan will increase the number of these meters throughout 2018, enabling more accurate consumption rates and more sophisticated consumption tracking. 

Employees participate in improving energy efficiency

Each HKScan employee can affect energy consumption in the company. HKScan is committed to the continuous improvement of energy efficiency, and good examples of this are the energy efficiency development teams that operate in production facilities. Ideas and suggestions from employees are collected and assessed, after which the development proposals are selected for implementation. The implementation is monitored and the results are reported to the development teams. In addition, HKScan runs annual energy efficiency training courses for personnel at certified production plants. The courses are based on the ISO 50001 standard.

Examples

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.
