Abstract: Since 2018, there has been a stable annual growth in the acreage of oilseed flax, which has led in Russia to an increase in the stem mass in the form of trusts, the primary processing of which allows to obtain an additional 417.9 thousand tons of flax fiber. Due to its inferior quality in comparison with short flax fiber, this fiber is not included in the sphere of interests of textile enterprises, but it is becoming increasingly popular in the construction industry because of its environmental friendliness. One of the options for using the same type of fiber from oilseed flax is to obtain a volumetric insulation from it. Therefore, there is a need to determine under what conditions of processing of the specified flax, the economic efficiency of the production of the same type of fiber and bulk insulation from it will be achieved. The domestic line of technological equipment produced by FGBNU FNC LC for the primary processing of oilseed flax trusts into the same type of fiber, as well as the TexInzh line for the production of volumetric insulation from it, is considered and analyzed. Calculation and analysis of technical and economic indicators of primary and deep processing of oilseed flax trusts from the Stavropol Territory and the Tyumen region were carried out. Recommendations are given to processing enterprises on acreage and operating modes. Primary processing of oilseed flax from an area of 2700 to 4000 hectares is cost-effective and may have optimal payback periods depending on the yield of the same type of fiber. Obtaining insulation from oilseed flax significantly increases the profitability of production and reduces the payback period by an average of 2 times, making them optimal.
