Alongside steel producer SSAB, FB Kedjor recently developed a completely new and ground-breaking solution for district heating supplier Söderenergi. District heating plants are extremely demanding environments, in which materials often corrode quickly. Some equipment has to be replaced after only a year or so. With a special sustainable steel from SSAB, however, Söderenergi developed a product with a service life thirty times longer than for earlier materials, and also offering environmental benefits in the form of greener electricity and heating for end customers, as well as reduced carbon dioxide emissions.
John Karlsson, Managing Director of FB Kedjor, tells us about the project:
“For the customer, the challenge lay in the plate at the bottom of the conveyor’s tipper trough breaking apart, destroying the actual supporting structure. At FB Kedjor, we took the initiative to bring together Söderenergi with specialists from SSAB, a company with which we were very familiar. Under our direction, a team was assembled to develop and assess a special steel for bottom plates that could withstand the extremely demanding conditions in the long term.”
Long term was the appropriate term: The special steel that was tested proved to have a service life of about 80 years. After about five years of analysis, development work, production and review, the team confirmed that everything had worked out perfectly.
“The change of material entails a number of positive and measurable environmental consequences. According to SSAB’s calculations, carbon dioxide emissions will decrease by about 1120 tonnes during the lifetime of the plant,” explains John Karlsson.
FB Kedjor has achieved similar sustainable solutions for other customers, in which it has also developed the materials used in the chain itself to achieve quantifiable positive effects.
“Our approach, which we call FB EcoUpgrade, begins with sitting down with customers and discussing their problems and what they want to achieve. Quite often, customers want us to help them manage their active environmental efforts, developing sustainable solutions, while generating economic benefits. In this way, we can support customers in assuming global responsibility and making a real difference,” says John Karlsson.
In his view, today’s customers have a growing understanding of the area of sustainability and they want to improve in this. Although price, reliability of delivery and quality, for example, remain important, many companies want to make a difference and are happy to make use of FB Kedjor’s sustainability skills.
“And that involves more than just the environmental aspects. The human aspect, including work-related injuries, stress and the working environment, is also important. FB Kedjor does more than deliver products, we are on a mission to help our customers advance their sustainability work. Put simply, we think long-term, for the sake of future generations,” says John Karlsson.
