Development of resource-saving technologies of recycling of domestic non-woody plant material in cellulose containing production

The resource-saving and ecologically cleaner technologies of obtaining pulp from the stems of agricultural plants were developed. Chemical composition and microscopic structure of representatives of Ukrainian plants were identified. Influence of basic technological parameters of obtained pulp by different methods of delignification on their indexes of quality. New methodology of efficiency comparison of domestic non-woody plant materials delignification processes is offered. It was identified, that investigated methods of delignification can be disposed in the following sequence by efficiency increasing of obtaining pulp from the stems of non-woody plant materials: soda – neutral sulphite - organosolv. Properties of bleached and unbleached pulp and possibility of their application were identified in composition of the paper-cardboard packing. Influence of basic technological factors of grinding, pre-hydrolysis, bleaching and hydrolysis processes on the indexes of pulp quality were studied.
