On the path toward the green starch factory

Lyckeby is a company owned by farmers and is therefore a company with close connection to nature and an active part of the whole value chain from potato to starch. To be able to do this, we sell potato seeds to the farmers and then Lyckeby advisory service is there to support the farmers and give them advice about how to irrigate, fertilize and other important aspects of growing potato. We met up with Alexandra Rolén, Process Engineer at Lyckeby, to find out a bit more what sustainability means for the production of the company.

Lyckeby has a focus on sustainability through the whole process and is working to find new ways to use our raw materials as smart as possible, Alexandra Rolén explains.

Especially during the campaign when the potatoes are harvested the production requires a lot of water. The campaign is on-going for approximately four months during which time 300 000 cubic meter of water is used in the factory in Kristianstad. Of this amount of water, Lyckeby needs to return at least 50% to the ground before the end of the year. However, this water can be re-used within the production multiple times before we return it, Alexandra says. 

Lyckeby is working to find even more efficient solutions on what to do with the water. The requirements for the water used are very high in this industry since the ingredient will be used in food. We are examining the options for water purification, both on incoming and outgoing water, continues Alexandra Rolén. Thanks to this, we have been able to lower the level of phosphorous in the water with 20-50%, a significant step and we hope to achieve more. 

Lyckeby is not only working with focus on the water but also on the efficiency within the production. We want to make the production even more effective by reviewing the production site to see if changes can be made that would both improve efficiency of the production as well as simplifying work tasks for our staff, Alexandra says.

Lyckeby currently focuses on efficiency when buying new machinery. The systems have to fulfill the requirements of being endurable at the same time as it have low energy or water costs. Right now, we have hopes with a newly installed equipment using less water and lower losses of starch. By focusing on efficiency gains, both costs can be reduced and the working environment can be improved.

We have a strong belief that sustainability is the future and we take small steps every day to come closer to the Green Starch factory, Alexandra Rolén concludes.
