Method of obtaining cellulose from a mixture of straw of cereal crops and wild plants

Abstract

This utility model relates to light industry, specifically to the production of cellulose, using a mixture of cereal straw and wild plant material as the starting material for the production of paper, cardboard, paper products, and packaging materials. The process involves obtaining cellulose from various types of raw materials, including plant waste, agricultural crops, and recycled materials. The use of alternative raw material sources reduces dependence on wood resources and promotes the efficient use of recycled materials, which significantly reduces the negative impact on the environment. This is achieved due to the fact that the raw materials are prepared by grinding, drying and, if necessary, soaking to open the cell walls and facilitate further processing. • Chemical treatment: At this stage, a combination of alkaline and acidic reagents in varying concentrations is used. Each type of raw material requires an individual approach: - For plant waste, higher concentrations of alkali can be used, which allows for effective destruction of fiber. - Agricultural crops can be processed using acids, which facilitates better cellulose extraction. • Temperature control: Optimizing the processing temperature and time depending on the type of raw material can significantly increase pulp yield. For example, using steam in the initial stages of processing helps open up the structure of the raw material. A key aspect of the technical solution is the use of a unique combination of chemical reagents that have not yet been used in the production of cellulose from alternative raw materials. The creation of cellulose with unique technical characteristics, suitable for various industries, allows for increased product versatility and facilitates the expansion of sales markets.
