YITHackathon

The primary mission of the innovation competition is to discover an eco-friendly and economically viable circular economy solution or product to replace or supplement the currently used road salt. 

Road salt has been used in Finland since the 1970s for de-icing, but its environmental impact is significant, causing structural damage and contaminating groundwater. Traditional road salt has several drawbacks, including environmental damage and high costs. Alternatives like potassium or sodium formates are used in critical groundwater areas but are significantly more expensive. Other methods, such as calcium chloride and calcium magnesium acetate, have their own limitations.

YIT, the leading construction company in Finland, is looking for alternative solutions that can be mechanical and/or chemical. The ideal solution has the potential to large scale distribution, economic viability and to meet the circumstances of the Arctic regions.

With the development of operations and equipment, the current chemical solutions for road salting are now primarily intended to prevent the formation of slipperiness on the road surface rather than combat already existing slipperiness. Traditional road salt is harmful for many reasons. It damages vehicles, infrastructure, and can potentially impact groundwater.  In some delicate cases, road salt has been replaced with potassium or sodium formates, but their use has been hindered by their tenfold cost compared to traditional road salt. In addition to the above, calcium chloride, commonly used in dust control, is also used to some extent in anti-skid treatment as a ready-made solution but the use of chloride is a problem. There are some existing solutions in North America that are based on calcium magnesium acetate (CMA). This ingredient is effective in aviation settings; however, its application on Nordic roads presents challenges due to its appeal to animals and its unpleasant odor. YIT is primarily seeking for a chemical solution suitable for the Nordic environment, capable of large-scale application, and economically feasible. The need for new solutions is vast. Just in Finland, there are nearly 10 000 kilometers or roads, utilizing road salt for de-icing (Traffic Customer Service 2025). In 2022, the estimated volume of used road salt was 120 thousand tons (YLE 2022).

If there is no suitable chemical solution, mechanical solutions replacing or reinforcing sand and gravel are welcomed. With the mechanical solutions, YIT is looking to see circular economy solutions that will preserve nature (gravel ridges and rock formations). Mechanically, solutions like blast furnace slag or woodchips exist, but none are safe for vehicles. 

YIT is a leading construction and development company, with over 110 years of experience in sustainable living environments. More than four thousand people are working in YIT, in Finland, Sweden, Estonia, Latvia, Lithuania, the Czech Republic, Slovakia and Poland. In 2023, YIT’s revenue was 2.2 billion euros, and it came from three business segments: housing, infrastructure, and business premises.

YIT’s Infrastructure segment focuses on building railroads, bridges, tunnels, structures, and facilities in demanding environments. YIT Road is in charge of the maintenance of roads, streets and areas as a year-round service which ensures the functionality and the preservation of value of the daily living environment. YIT Road offers a full-service solution for road maintenance as well as networks all around Finland and an operating model and service level suitable for the needs of a municipality. Additionally, it offers life-cycle models for road maintenance. A top priority for the company is that the level of road maintenance meets the agreed standards of the customer, as well as climate requirements.

YIT Road offers technical competence and smooth subcontractor culture to its customers, with decades of experience. Its’ finalized, advanced operating systems used in the planning, implementation, monitoring, and reporting of the contract are especially important, as part of the reliability and cost-efficiency in road maintenance. In the future, YIT is focusing its investments on sustainable infrastructure, which supports society as a whole.
