New Saw Technique Increase Profit for Sawmill Industry

Published: 23 March 2015

A product that scan logs in real time and adjusts the saw-blades tilt after the log's curvature - this is the idea that will save large sums of money for the sawmill industry. Mats Ekevad, Professor at Luleå University of Technology are now looking for an industrial partner who wants to develop his idea into a product

– Todays sawmill produce large quantaties of lumber and will be able to save millions of euros with my idea. After the initial investment, the sawmill will see return on investment after approximately two years. We are already in talks with some companies to develop a product, says professor Mats Ekevad.

The idea is based on a mathematical algorithm that controls the saw blade more efficiently by tilting it after the log's curvature. According to estimates, the savings will be one euro per cubic meter stock - which would mean gains of 200 000 - 500 000 euro per year for a mid-sized sawmill.

–  You are not able to tilt blade today and it leads to big spill. With my method, you can extract the optimal effect for individual logs. Other benefits that we haven't calculated yet is that you can cut logs with greater curvature that can't be cut today, and also that the saw blades tear less, says Mats Ekevad.

The idea has been reviewed by the swedish and international Patent Office. The market research done by LTU Business AB also shows that no similar idea is competing in the current market.

– Our analysis shows that the idea has high competitiveness in the international market. The sawmill industry is global and commercialization will therefore give benefitial results. In addition to that we also see potential for further research that will increase the longevity of the product, says Lena Forsberg, business developer at LTU Business AB.
