Pulp and paper mill by-products as soil amendments and plant nutrient sources

Pulp and paper mill sludges are produced from primary and secondary treatment of wastes derived from virgin wood fiber sources, recycled paper products, and non-wood fibers. Sludges and sludge composts may be utilized in agriculture to increase soil organic matter, improve soil physical properties, provide nutrients, and increase soil pH. Positive effects of primary, deinking, and low-nutrient combined sludges on soil quality are primarily due to increased soil organic matter, aggregation, water holding capacity, infiltration rate, and cation exchange capacity. Nitrogen and P immobilization are often induced by primary and deinking sludges, but can be overcome by delayed planting, adding N and P, planting of legumes, or composting. Improved crop production obtained with secondary treatment sludges is most often attributable to enhanced nutrient availability, particularly N, but improved soil physical properties are implicated in some studies. Pulp and paper mill sludges and sludge composts are useful soil amendments and plant nutrient sources.

Standard Value

One of the method to use pulp and paper mill sludge was convert it become a compost. This research result showed that time variation of compost have different physical and organic matter properties. In physical properties, 3 months of compost had 12.57% moisture content, while organic matter contain 10.56% carbon, 1.07% nitrogen, and 9.87 C/N ratio. For 4 months compost had 6.79% moisture content, 11.88% carbon, 0.91% nitrogen, and 13.05 C/N ratio. Nutrients content from both composts appropriate with the standard value of National Standarisation Body.

Bacterial community compositions from 10 pulp- and paper-mill treatment systems were compared using both traditional and molecular techniques. 16S-RFLP (Random Fragment Length Polymorphisms) analysis was used to examine the genotypic profiles of the whole bacterial community of each treatment system. Although all the communities shared approximately 60% of their DNA band pattern, as determined by computer-assisted cluster analysis, each community displayed a unique profile that was stable over time under normal operating parameters. Reverse Sample Genome Probing (RSGP) and 16S-RFLP were used to compare the culturable bacterial communities of several geographically separated pulp-mill biotreatment system communities. There was little overlap in the composition of the culturable community between mills at the genus level. Furthermore, RSGP variation was almost as high within a mill as between mills. Partial sequences of the 16S rRNA genes from culturable isolates identified Bacillus spp., Pseudomonas spp., and Xanthobacter as some of the dominant species. Finally, several 16S rRNA genes from two whole community 16S RNA gene libraries were partially sequenced and identified as similar to unknown α-, β-, and γ-Proteobacteria, Ralstonia, Alcaligenes, Nitrospira, Firmicutes, and clones representing the new Holophaga/Acidobacterium phylum. These findings suggest that although these pulp- and paper-mill biotreatment communities perform similar functions, they are populated by unique mixtures of species.Key words: biodiversity, 16S-RFLP, secondary treatment, pulp mills.

Hydrophobic Acids

Meeting the regulatory discharge standards for pulp and paper mill wastewater has become ever more difficult because of its recalcitrant and colored dissolved organic matter (DOM). In this study, the variation of DOM from the secondary effluent of pulp and paper mill wastewater before and after coagulation was investigated based on hydrophobicity/hydrophilicity, apparent molecular weight (MW) and fluorescence. DOM fractions of the secondary effluent were all with the apparent MW <20 kDa. Particularly, the hydrophobic acids (HOA) fraction, mainly composed of humic-like materials, was the major component, and it also had the highest color and SUVA254 (UV254 to dissolved organic carbon ratio). Hydrophilic bases (HIB) and hydrophilic neutrals (HIN) fractions were the other important parts besides HOA. Coagulation can remove all DOM fractions to different extent, and it was more effective for organic compounds with MW > 5 kDa. The removal efficiencies of humic-like, fulvic-like and soluble microbial by-product-like constituents in HOA and HIB fractions were much higher than in other fractions. Even so, the coagulation effluent still contained large amounts of contaminants with complicated fluorophores and apparent MW <5 kDa, and HOA and HIN fractions were also the major parts in the coagulation effluent.
