The paper is presented results of the technical and economical evaluation of the production of cellulose for the solving the problem of utilization of agricultural residues of lignocellulosic nature. Non-wood was used in this work for pulping. Treatment was proposed to carry out with the application of peracetic acid. Such method allows to obtain cellulose, lignin, furfural and xylose. Spent peracetic solution can be used to precipitate lignin and for regeneration of acetic acid and to recover furfural and xylose. A technological scheme for the processing of plant raw materials by this method has been developed. Economic efficiency was calculated. The sale of by-products can provide additional financial benefit. Such an approach in the processing of significant volumes of agricultural waste is effective from an economic point of view, as well as from an environmental point of view, as it allows to reduce the negative impact on the environment and to ensure its protection.

The research is connected with the solving the problem of rational utilization of agricultural residues by the creation of resource-saving method for their efficient conversion into value-added products. Wheat straw was used in this work in chemical processing. Treatment was carried out with the application of formic/acetic acid mixture. Thus, cellulosic pulp was obtained. The spent solution was used to precipitate lignin. The structure of lignin was investigated. The results indicated that formic/acetic acid treatment was quite effective in isolating cellulose from wheat straw and in recovering lignin. Wheat cellulose is a promising fibrous material for the application in paper industry. Wheat lignin can be considered as a material for biosorbent preparation.
