Abstract
The problem of waste processing at oil processing plants and the urgent task of finding alternative sources of raw materials for the pulp and paper industry became the impetus for the development of methods for obtaining fibrous semi-finished products from sunflower husk. The method of alkaline-peroxide low-temperature treatment with subsequent grinding was used to obtain a fibrous semi-finished product of high yield (yield 82-86%), the method of alkaline-sulfite cooking was used to obtain cellulose of high yield (yield 56-68%). The study of the morphological characteristics of the fibrous semi-finished products obtained from sunflower husks showed that the mass of medium-fiber and long-fiber fractions suitable for paper production is about 50% in high-yield cellulose, and up to 70% in the fibrous semi-finished product of high yield. This allows us to consider these semi-finished products as potential raw materials in the production of paper and cardboard, taking into account modern achievements in paper technology, with the use of various chemical additives and methods for preparing paper pulp.
