Baltic region’s largest birch lumbermill celebrates 17 years of using UMP Technika machinery to reduce wood waste to zero.

19 March, 2020 | Dalintis:

Located near Ukmergė, Lithuania, the company employs over 120 workers and operates 80,000 square meters where it stores, saws, dries and mills birch logs into wood blanks which are sold for further processing.

With the help of UMP Technika, the company has achieved a point where no wood is wasted. The first part of the production process cuts green birch logs into planks which are then dried in kilns. Leftover cuts which are unusable get shredded using UMP Technika’s VVSG1000 into chips and fed to fuel those kilns repurposing waste into sustainable mean of facility heating. The specific UMP Technika shredder used in this configuration uses a 1000mm wide second generation “V” rotor with horizontal in-feed and belt conveyors to transport the now chipped mass to the kilns.

The second stage of the process then cuts now dried planks into wood blanks which are sorted and stacked for transport. Some of those blanks get sorted out due to their natural deformations, such as branch holes, yellowing and other spoilage. Unfit leftovers then get shredded with UMP Technika VVS-800 single shaft shredder and put through the MM-1500 hammer mill to join sawdust from the cutting process for the briquetting process.

This is where the primary cost-saving measure comes in. The company uses four BP-500 hydraulic briquette presses to create an average of 25 tonnes of briquettes every day and have been doing so for over 15 years now without any adhesives, or glue. Compared to selling sawdust “as is”, depending on the current market prices the company gains additional 20€-60€ per single tonne. The company further increased those gains in 2020 by installing an automated briquette packing system with automated size and weight controllers, as well as a brochure feeder, saving on manual packing of the bags, and improving the pack’s quality.
