“Bumax’s improvement is fantastic and it’s so rewarding to see that our support and our methods have become so useful to companies,” says Ida Johansson, doctoral student in energy systems at the University of Gävle.

Ida Johansson has participated in the energy mapping at Bumax, one of the largest export companies in Gävleborg. Bumax is a world-leading manufacturer of premium stainless-steel fasteners for submarines, oil rigs, cancer care, space research and much more.
“They described their entire flow with operation times and machine use, and we calculated the energy balance and provided suggestions regarding effective measures,” Ida Johansson says.
To Ida, it important to support small and middle-sized companies. More often than not, these are both very interested in and see the benefits of energy efficiency, but find it difficult to engage in this process on their own as they need to prioritise production at all times.
At the present time, Ida is evaluating their project and she is communicating their results to other European regions in an EU project.
“As researchers, we learn a great deal from working out in the companies, since they are expert on their own activities and theories do not always work in practice,” Ida Johansson explains.
Bumax is a world-leading manufacturer of premium stainless-steel fasteners and one of the largest export companies in Gästrikland. They deliver stainless steel fasteners for submarines, oil rigs, cancer care, space research and much more.
The plant with its head office in Åshammar in Gästrikland has managed to halve their energy and electricity consumption.
“This is a major achievement for a manufacturing company with a large factory, and it’s good both for the environment and for our competitiveness,” says Managing Director Patrik Lundström Törnquist.
For this project, the University of Gävle gathered around 50 small and middle-sized companies from Gävleborg; for three years these were given access to researchers and experienced energy experts from the University. The first step was to carry out energy mapping to calculate the current energy consumption and then to suggest cost-efficient measures.
“We have disseminated knowledge and the result is that the energy consumption in the companies has been reduced by 16 percent on average. We are very grateful for having been able to take this journey, which has given us new knowledge as well,” says Patrik Thollander, professor in energy systems at the University of Gävle
Patrik Thollander tells us that they are continuing with a project in which the companies practice making their value streams more efficient and that another project focuses on securing energy supply. Patrik welcomes more companies to participate in these projects.
“There is a huge interest for our project in other European regions. They want to hear what we have done,” Patrik Thollander says.
