Synthetic organic compounds (SOCs) are reported as xenobiotics compounds contaminating the environment from various sources including waste from the pulp and paper industries: Since the demand and production of paper is growing increasingly, the release of paper and pulp industrial waste consisting of SOCs is also increasing the SOCs’ pollution in natural reservoirs to create environmental pollution. In pulp and paper industries, the SOCs viz. phenol compounds, furans, dioxins, benzene compounds etc. are produced during bleaching phase of pulp treatment and they are principal components of industrial discharge. This review gives an overview of various biotechnological interventions for paper mill waste effluent management and elimination strategies. Further, the review also gives the insight overview of various ways to restrict SOCs release in natural reservoirs, its limitations and integrated approaches for SOCs bioremediation using engineered microbial approaches. Furthermore, it gives a brief overview of the sustainable remediation of SOCs via genetically modified biological agents, including bioengineering system innovation at industry level before waste discharge.

The continual growth of pulp and paper industry has led to the generation of tremendous volumes of fly ash as byproducts of biomass combustion processes. Commonly, a major part of it is landfilled; however, updated environmental regulations have tended to restrict the landfilling of fly ash due to rising disposal costs and the scarcity of suitable land. The pulp and paper industries are therefore urgently seeking energy-efficient mechanisms and management for the beneficial use of fly ash in an ecological and economical manner. This paper offers a comprehensive review of existing knowledge on the major physicochemical and toxicological properties of pulp and paper mill fly ash to assess its suitability for various bound and unbound applications. The current state of various methods used for the valorization of pulp and paper mill fly ash into more sustainable geomaterials is briefly discussed. This paper also presents promising and innovative applications for pulp and paper mill fly ash, with particular reference to agriculture and forestry, the construction and geotechnical industries, and the immobilization of contaminants. It was identified from a literature review that modified pulp and paper mill fly ash can be environmentally and economically advantageous over commercial coal-based fly ash in various sustainable applications.

Biological systems have been employed successfully for manv years in the treatment of pulp and paper mill waste water. Previously, not very much was known about enzymes and their possibilities in pulp and paper industry wastewater treatment. There is currently a lot of research activity in the enzymology of lignin degradation. Ligninase, cellulase, peroxidase, etc. are the most important enzymes, especially peroxidase, which is used for color removal in bleaching effluents. It is also possible to mix enzymes together with special microbes, which normally do not have high enzvme activity, and remove recalcitrant and harmless compounds from wastewater. The use of novel enzymes and rDNA technology in sludge and wastewater treatment will also be discussed.

Removal Efficiencies

A wastewater from an integrated paper mill with a COD of 1200 mg/dm3 was anaerobically treated in a multi-stage reactor. The BOD7 removal efficiencies of 60-75 % were achieved at maximal loading rates of 5-6 kg COD/m3d and HRT of 4-6 hours due to the granular sludge. Industrial sulphite evaporator condensates from Ca- and Na-processes were treated in anaerobic filters containing light gravel, plastic foam and power plant slag as filter media. The BOD7 removals of 78 % on average were achieved at loading rates of 1.8-3.3 kg COD/m3d with Ca-process evaporator condensates and 80 % BOD7 removals were achieved with Na-process condensates at loading rates of 3.5-4.1 kg COD/m3d.

Pulp And Paper Industries

The pulp and paper industry is generally considered the most technologically progressive of the forest industries. A study employing Solow's method indicated a rise in the index of technological change of 50% between 1940 and 1960. This compares with a 547% increase for the chemical industry. Derivation of the capital production function for the pulp and paper industries shows that all increases in productivity, 1940–1960, were due to change in technology. There is also some indication that optimal plant size has been reached.

The City

Introduction. Analysis of literature has shown genotoxicants (mutagens and carcinogens) to be present in the atmospheric emissions of pulp and paper industry (PPI). Moreover, among PPI workers from different countries, there was identified an additional risk of cancer, which suggests its high probability among residents of the cities where the PPI is located. The recognized index of genotoxic effects is an increased level of genome instability, which is determined, in particular, in the micronucleus test. The scope of the study - the comparative analysis of the effects of genomic instability in the two tissues - blood lymphocytes cultured with Cytochalasin B, and buccal epithelial cells in the second grade school children (8-9 years old, boys and girls), whose schools were located at different distances from the pulp and paper mill. Material and methods. The study was carried out in the city of Koryazhma, the Arkhangelsk Region (42000 citizens), where the pulp and paper plant as the city-forming industry was located. For the analysis, we subdivided the territories on which the schools were located, into 3 groups according to their distance from the pulp and paper mill. The effects of genomic instability were determined by cytome analysis in the micronucleus test. Results. Cytome analysis of cultivated lymphocytes demonstrated that levels of genome instability indices (including cell frequencies with micronuclei and nucleoplasm bridges, apoptosis, as well as changes in the spectrum of cell populations) to decrease along with the rising the distance between the pulp and paper mill and schools where the children go. In buccal epithelial cells, the manifestations of genomic instability effects were less systematic, which did not allow making a definitive conclusion. At the same time, in both tests, gender differences in the results of cytome analysis were revealed (for example, the alteration of frequency of lymphocytes with genetic damage dependence on the distance between schools and the PPI was more pronounced among boys). Conclusion. According to the results of this study and taking into consideration the data of literature, we hypothesized that the discovering of gender dimorphism in the effects of genome instability may indicate the presence of toxic and/or genotoxic compounds in an environment.
