The addition of PMS increased …
— 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 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 …
This study aimed to investigate the beneficial reuse of paper mill sludge as landfill cover and bottom liner material in municipal solid waste landfills. For this purpose, two-dimensional finite element analyses of a typical landfill geometry were carried out using PLAXIS finite element program. The results of the analyses were evaluated in terms of displacement …
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 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.
Herein, we prepared carbon quantum dots (CQDs) by one-step oil-thermal method using paper mill sludge (PMS) as precursor, and developed a ratiometric fluorescence method for the determination of COP. The structural and optical properties of PMS-CQDs were evaluated through HRTEM, FT-IR, XPS, XRD, UV-vis, fluorescence, zeta potential and ...
Keywords: Finite element analysis; Hydraulic barrier; Landfill cover; Paper mill sludge 1. Introduction The pulp and paper industry produces millions of tons of paper per year. This production leads to the generation and accumulation of significant amounts of waste sludge called the paper mill sludge that should be disposed of [1].
— 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 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 ...
