Description of Facility and Services

From the last century, more precisely from its 30’s, the fiberboards production process in the Lesonit Ilirska Bistrica plant has featured constant growth and development, meeting in the same time the overall technology demands in the sphere of final products production especially in furniture, civil construction and transport means production industry. The fiberboards production was originally carried out by a wet-based technological process which required, due to its harmful impact on the environment, a waste water treatment, a demanding technological procedure causing additional operating costs.

Following the above said and also due to the fiberboards production development trend after 1965, in the Lesonit Plant a decision was taken to construct a new production plant; For ecological reasons, the plant was converted to dry-process high-density fiberboard with firm and smooth surface on both sides, thickness from 3.00 to 6.00 mm, or to semi-hard fiberboard in the thickness range from 7.00 to 12.00 mm, which featured significant advantages over fiberboards produced by a wet-based process or over chipboards.

In the drying process, the fibers pass from the defibering plants directly into a drier where they are dried down by combustion flue gases to 5-10% of moisture content. The boards’ formation is carried out by air while their final compression is performed in the hot pressing phase.

The new dry-process fiberboards production plant located in the area of wood and chemical industry of the Lesonit Plant in Ilirska Bistrica occupies the surface of 35,000 m2, wherefrom there are 15,680 m2 of constructed area. Yearly production of 2100 X 5200 mm fiberboards, thickness 16 mm, amounts to 52,000 tons, or 16,240 m2 respectively.

Within the overall construction project IBE has taken the role of the main Design Engineer and author of complete design documentation, with additional performance of consulting engineering services and complete professional supervision.
