“…The method has shown favorable results in treating industrial wastewater with heavy water pollution, particularly in the pulp and paper industry [40]. Adsorption involves the use of adsorbents to adsorb pollutants in wastewater, and commonly used adsorbents include activated carbon and zeolite [23,59]. Adsorption is achieved through a chemical reaction occurring between the surface of an adsorbent and contaminants in the wastewater.…”

“…The US Environmental Protection Agency (EPA) surveyed some paper mills and found that 60% of wastewater discharged from the paper mills contained dioxin components [22]. Dioxin exhibits the characteristics of teratogenicity, carcinogenicity, and mutagenicity [23]. It not only affects the secretion of hormones that feminize males and influence the growth and development of children but can also causes multiple brain neuropathy and acute toxicity [24].…”

“…Among them, sewage treatment is the most commonly used technology at present; its purpose is to reduce pollutants in wastewater. Organic matter in sewage is primarily treated by biological treatment, whereas inorganic matter is primarily treated via chemical treatment to reduce pollutants [23]. Biological treatment is based on the microbial analysis of organic matter in wastewater.…”

The pulp and paper industry plays an important role in the global economy and is inextricably linked to human life. Due to its large scale, the production process generates a large amount of wastewater, which poses a major threat to the environment. The sustainable utilization and safe treatment of pulp and paper wastewater can effectively reduce environmental pollution, improve resource utilization efficiency, protect water resources, provide economic benefits for pulp and paper enterprises, and thus promote the green and sustainable development of the pulp and paper industry. Therefore, this study discusses the pollution components of pulp and paper wastewater and their impact on the environment and human health. In this review, we aim to explore the sustainable development of pulp and paper wastewater by summarizing the characteristics of current pulp and paper wastewater, the commonly used treatment methods for pulp and paper wastewater, the application of pulp and paper wastewater recycling, and the future development direction of pulp and paper wastewater.

“…Although this industrial sector contributes a significant role to the world’s economy, this industry in particular is known to be one of the largest producers of wastewater worldwide emanated during subsequent industrial operations ( Bui et al, 2022 ; Namdarimonfared et al, 2023 ). From the different stages of the paper-making process, wastewater from the bleaching process is probably the major problem of PPMs ( Oke et al, 2017 ; Kumar et al, 2020 ; Coimbra et al, 2021 ). It is estimated that freshwater ranging from 273 to 450 m 3 is essential to make 1 tonne of paper in PPMs and about 60–300 m 3 of bleached wastewater is generated ( Mittar et al, 1992 ).…”

Pulp-paper mills (PPMs) are known for consistently generating a wide variety of pollutants, that are often unidentified and highly resistant to environmental degradation. The current study aims to investigate the changes in the indigenous bacterial communities profile grown in the sediment co-contaminated with organic and inorganic pollutants discharged from the PPMs. The two sediment samples, designated PPS-1 and PPS-2, were collected from two different sites. Physico-chemical characterization of PPS-1 and PPS-2 revealed the presence of heavy metals (mg kg−1) like Cu (0.009–0.01), Ni (0.005–0.002), Mn (0.078–0.056), Cr (0.015–0.009), Pb (0.008–0.006), Zn (0.225–0.086), Fe (2.124–0.764), Al (3.477–22.277), and Ti (99.792–45.012) along with high content of chlorophenol, and lignin. The comparative analysis of organic pollutants in sediment samples using gas chromatography–mass spectrometry (GC–MS) revealed the presence of major highly refractory compounds, such as stigmasterol, β-sitosterol, hexadecanoic acid, octadecanoic acid; 2,4-di-tert-butylphenol; heptacosane; dimethyl phthalate; hexachlorobenzene; 1-decanol,2-hexyl; furane 2,5-dimethyl, etc in sediment samples which are reported as a potential toxic compounds. Simultaneously, high-throughput sequencing targeting the V3–V4 hypervariable region of the 16S rRNA genes, resulted in the identification of 1,249 and 1,345 operational taxonomic units (OTUs) derived from a total of 115,665 and 119,386 sequences read, in PPS-1 and PPS-2, respectively. Analysis of rarefaction curves indicated a diversity in OTU abundance between PPS-1 (1,249 OTUs) and PPS-2 (1,345 OTUs). Furthermore, taxonomic assignment of metagenomics sequence data showed that Proteobacteria (55.40%; 56.30%), Bacteoidetes (11.30%; 12.20%), and Planctomycetes (5.40%; 4.70%) were the most abundant phyla; Alphproteobacteria (20.50%; 23.50%), Betaproteobacteria (16.00%; 12.30%), and Gammaproteobacteria were the most recorded classes in PPS-1 and PPS-2, respectively. At the genus level, Thiobacillus (7.60%; 4.50%) was the most abundant genera grown in sediment samples. The results indicate significant differences in both the diversity and relative abundance of taxa in the bacterial communities associated with PPS-2 when compared to PPS-1. This study unveils key insights into contaminant characteristics and shifts in bacterial communities within contaminated environments. It highlights the potential for developing efficient bioremediation techniques to restore ecological balance in pulp-paper mill waste-polluted areas, stressing the importance of identifying a significant percentage of unclassified genera and species to explore novel genes.
