Paper mill sludge (PMS) solids are predominantly comprised of cellulosic fibers and fillers rejected during the pulping or paper making process. Most sludges are dewatered and discharged into landfills or land spread at a cost to the mill; creating large economic and environmental burdens. This lignocellulosic residual stream can be used as a ...

 — In fact, the spreading of paper mill sludge to land has been recorded since the 1950s and has, for example, been considered a common practice for more than 30 years in the UK (CPI, 2015; Norrie and Fierro, 1998). Although transport costs must be taken into account, similar transport costs are incurred by any offsite movement (e.g. for ...

Pulp and paper mill sludge presents a significant waste management challenge, but opportunities in land applying this nutrient-rich source of organic matter look promising, with many potential benefits. FEECO has helped hundreds of companies to transform their waste material into a value-added product – paper sludge included. We use our state ...

 — The high moisture and viscosity characteristics of oily cold rolling mill (CRM) sludge led to limitations in its recycling. In this paper, the results of using quicklime as a conditioning agent to improve the dewaterability of the oily CRM sludge cake were reported. Quicklime was selected as the best conditioning agent through conditioning ...

 — In this study, lime sludge from recovery section of the paper mill is used in mortar in its as-received condition and in calcined condition to partially substitute cement. Calcination of lime sludge is performed at the relatively lower temperature of 650–750 °C, which takes less energy input than the industrial process of calcination.

 — Pulp and paper mill sludge is composed of cellulosic waste and clay and is rich in microorganisms that can benefit horticulture. However, its application in horticulture has received less research attention. Field and greenhouse studies were carried out to determine if sludge from a case study industry can replace the typical cellulosic additive …

sludge solids are generated annually by paper and pulp mills.17 To manage those large quantities, incineration of the sludge is often used. Nevertheless, the high water content in the sludge makes sludge management costly and can stand for up to 65% of the total operating costs at paper mills.19 Paper mill sludges

 — The wastewater that can be treated in an MDC comes from different sources such as petroleum refinement processes, sewage sludge, wetland and paper mill sludge [106, 107]. This water would have ...

 — This study evaluated the impact of soil modifiers on seed germination and soil quality. Mixtures of paper mill sludge (PMS) with camellia oilseed cake (CO) and peat moss (P), as well as with oilseed cake of toothache tree (TO) and peat moss (P), showed promising results as biostimulants for seed germination. The addition of PMS increased …

Porous carbon material from paper mill sludge has previously been examined as a supercapacitor electrode material.32 The carbon material showed remarkable electro-chemical performance in organic and ionic liquid electrolytes. However, because organic and ionic liquid electrolytes are costly, the potential of paper sludge-derived carbon …

 — This paper evaluates the environmental impacts of different alternatives for handling of sludge from paper and pulp mills in Sweden, using Life Cycle Assessment (LCA). The common practice of incineration of biosludge with energy recovery followed by landfilling of ash (System A) was compared with the alternative of digesting sludge …

 — The article describes the compositions with red clay, as principal component, for utilization of paper production sludge and scrap glass to fabricate red ceramics at sintering temperatures of 700 ...

 — In this study, the primary paper-mill sludge characterized as containing 51% glucan was used to optimize the enzymatic saccharification process for the production of bioethanol using a Box–Behnken design (BBD). Polyethylene glycol 4000 (PEG-4000) surfactant-assisted enzymatic saccharification of dried primary sludge (DPS) showed a …

 — Pulp and paper mill sludge (PPMS) is an organic residual generated from the wastewater treatments. PPMS management involves economic, environmental and …

The wastes from pulp and paper mills are both of organic and inorganic types. Most of the biomass generated from pulp and paper mills is organic residues. Black liquor consists of organic polymers (lignin, polysaccharides, and resinous compounds of a low molar mass) and inorganic compounds mainly soluble salt io…

 — 1. Introduction. The oily cold rolling mill (CRM) sludge is a solid waste generated from the cold rolling steel process comprising a dense slurry of iron fines in lubricating oil and water with other impurities including heavy metal. 1 The oil in CRM sludge is derived from lubricants and equipment used in the cold rolling process of steel …

 — The scientific case for persuading farmers to accept mill sludge on their land probably needs to be based on the potential improvements to soil con- dition, rather than on the sludge's nutrient content: in this there is a contrast with sewage sludge. Pro- vided that land which has received mill sludge at rates no higher than 20 t DM/ha.year is ...

 — In Mindanao, Philippines, there is a potentially good Ca-rich waste material locally available called sugar-mill lime sludge, an industrial by-product in the manufacture and refining of sugar from sugarcane, which may contain up to 80% of Ca in the form of lime (Opiso et al., 2017).

 — The electrode material performance of the activated biocarbon from paper sludge clearly shows its potential for electrochemical energy storage. The reported results present an exciting potential …

 — The valorization of a South African paper mill waste sludge into an activated biocarbon electrode material for energy storage application is reported. The valorization method is a two-step synthesis that comprises hydrothermal carbonization and NaOH activation of paper mill waste at 700 °C to produce activated biocarbon.

 — About 40–50 kg of sludge (dry) is generated in the production of 1 tonne of paper at a paper mill and of that approximately 70 % is primary sludge and 30 % secondary sludge.

 — Paper mill sludge is a mixture of primary and secondary sludge in the treatment of papermaking wastewater. The primary sludge is mainly composed of fiber materials (such as cellulose fibers), inorganic fillers (such as CaCO 3, kaolin and titanium dioxide) ( Zhang et al., 2020c ) and solids from different treatment processes, like pulp …
