Strategy for the Management of Pulp and Paper Industry’sWaste Containing Lignosulfonates

The pulp and paper industry’s multi-tonnage liquid waste is spent cooking liquor containing lignosulfonates, which disposal and processing remains one of the most complex environmental and technological problems, which should be solved. Lignosulfonates have unique colloidal-chemical properties, which determines their high resource potential. However, lignosulfonates’ composition instability often does not provide the properties and indicators set by the consumer. Changing market conditions require constant waste monitoring and modification, that prevents the widespread lignosulfonates use in industrial practice. In this paper, the causes for the formation of lignin-containing waste and its impact on the environment are considered. A strategy for lignosulfonates utilization has been developed, as well as promising methods for these wastes processing and disposal, which will expand the use of lignosulfonates and reduce the pulp and paper industry negative impact on the environment.

Solid Form

The pulp and paper industry produces liquid waste in its production process. Liquid waste in solid form of sludge can be utilized as compost fertilizer. Research conducted at PT. Indah Kiat Pulp and PT Arara Abadi Rasau Kuning District, Riau Province. The aim of this research is to know the effect of compost fertilizer from pulp and paper industry waste on Eucalyptus pellita growth and to determine the most appropriate dose of compost for growth of Eucalyptus pellita. The research method was done by applying compost in 3-month Eucalyptus pellita with dosage of o gram, 750 gram, 1000 gram and 1250 gram. Parameters measured over 3 months were plant height, plant diameter and number of leaves. Provisi on of compost fertilizer from pulp and paper industry waste has no significant effect on Eucalyptus pellita growth. Visually, the most appropriate dose of compost for the growth of Eucalyptus pellita is a dose of 1000 grams.

Pulp And Paper Mill

The article analyzed the technogenic load of a pulp and paper mill as a source of waste generation. Based on the analysis, the waste groups of the pulp and paper industry with the excess of education standards were identified, and among these groups suitable for recycling and reuse. Among such wastes, osprey was isolated - waste from the processing of sewage sludge from the pulp and paper industry. The stages of the technological process of manufacturing pulp and paper products from recycled materials were also considered. An analysis of scientific and technical information was carried out, within the framework of which the features of the main technical solutions in the field of processing and disposal of osprey were investigated. An electro-osmotic plant was developed, the essence of which is to achieve maximum energy efficiency in the process of dewatering sewage sludge from the pulp and paper industry. According to the results of the experiments, a correlation assessment was made of the parameters of electroosmotic dehydration: reduction of the residual mass of the osprey and current strength on the plant plates during electroosmosis, from which it follows that the values of the cross-correlation coefficient are significantly affected by the electric field strength of the electroosmosis.

Cooking Liquor

The work is devoted to increase in complexity of use of wood raw materials – one of the most important directions in solution to complying with the modern requirements of rational environmental management and environmental protection.Features of impregnation by bisulfite sulfite cooking acid and regularities of bisulfite delignification of young and ripe fir-tree and birch wood have been investigated. It is shown that young thin wood of both breeds becomes impregnated by bisulfite sulfite cooking acid much quicker, than ripe. The nature of delignification processes for young and ripe wood are identical, however intensity of processes is much lower for young wood.It has been established that cellulose derived from young wood is ground easier and has higher mechanical strength rates than from ripe. However cellulose from young wood is dehydrated slightly more difficultly and has the increased water-retaining what is connected with differences in sizes and properties of fibers of young and ripe wood.Cellulose yields of young and ripe wood differ insignificantly. Cellulose from young birch wood characterized by a somehow lowered owing due to the higher content of knots of this wood.Young wood is dignified by bisulfite cooking liquor without difficulties, but slightly more slowly in comparison with the corresponding ripe wood breed. The research results showed that the young (thin) fir-tree and birch wood of which is formed at cleaning cutting is the considerable reserve stock of wood raw materials which can be successfully utilized fibrous semi-finished products production, in particular in bisulfite cellulose.

The World

The peculiarities of the development of the world pulp and paper industry have been considered in this study. The types of products are described and the traditional type of production process within the industry has been characterized. The main exporters of pulp and paper products in the world have been identified. The dynamics of production indicators for printing paper, pulp, chemical wood pulp, cardboard, coated paper in the world market has been analyzed. A review of the pulp and paper industry of Ukraine was carried out on the basis of indicators of export and import of pulp from wood or other fibrous materials, export-import balance, sales of pulp, paper and cardboard in domestic and foreign markets. The current trend in the dynamics of export-import balance in the bulk trade of wood or other fibrous pulp for the period 2016-2020 indicates a significant predominance of imports over exports, which can be attributed to the lack of positive developments in the segment of deep wood processing in the forest sector. The key factors of modern transformations of the world market of pulp and paper products are stated: the growing demand for viscose pulp products used in the manufacture of new types of plastics; growing demand for recycled paper in the context of environmental friendliness of the material; growth in demand for sanitary and hygienic types of paper, which is associated with the growth of income and population on a global scale; growing demand for packaging paper and cardboard as an ecological type of packaging material; falling demand for all types of sulfite cellulose due to the negative impact on the environment; falling demand for all types of writing paper due to the technological revolution and changes in the format of data storage as a result of digitalization processes. The global pandemic COVID-2019, the processes of digitalization and human development on the basis of the concept of sustainable development have been considered as the main drivers of transformation processes in the industry. The main priorities of development of enterprises of pulp and paper products in the conditions of modern transformations for the purpose of increase of the international competitiveness of industrial centers on the world arena have been specified.

Agricultural residues and energy crops are promising resources that can be utilized in the pulp and paper industry. This study examines the potential of co-cooking nonwood materials with hardwoods as means to incorporate nonwood material into a paper furnish. Specifically, miscanthus, switchgrass, and corn stover were substituted for poplar hardwood chips in the amounts of 10 wt %, 20 wt %, and 30 wt %, and the blends were subjected to kraft pulping experiments. The pulps were then bleached with an OD(EP)D sequence and then refined and formed into handsheets to characterize their physical properties. Surprisingly, all three co-cooked pulps showed improved strength properties (up to 35%). Sugar measurement of the pulps by high-performance liquid chromatography suggested that the strength increase correlated with enriched xylan content.
