Paper mill sludge (PMS) is a solid by-product of the pulping and paper-making process, produced in large quantities of about 300– 350 million tons every year (Ioelovich, 2014).
2012/10/14/ · Purpose This paper presents an assessment of the production of polyhydroxyalkanoates (PHA) in biomass sourced from wastewater treatment plants (WWTPs). The purpose was to examine both the potential for more generic utilization of waste activated sludge as biomass for PHA production and the quality of the polymers produced.
2020/4/1/ · A new process for the production of bioethanol from paper mill sludge (PMS) is described in this work. PMS biomass feedstock was processed via the simultaneous saccharification and fermentation
2010/1/23/ · Paper mill sludge is a solid waste material composed of pulp residues and ash generated from pulping and paper making processes. The carbohydrate portion of the sludge has chemical and physical characteristics similar to pulp. Because of its high carbohydrate content and well-dispersed structure, the sludges can be biologically
Co-composting dewatered paper mill sludge (PMS) and hardwood sawdust, two readily available materials in Canada, was investigated using uncontrolled and controlled In tank processes. The composted materials were characterized for total C and N, water-soluble, acid-hydrolyzable, and non-hydrolyzable N, extractable lipids, and by Fourier
2021/6/15/ · Introduction. Paper mill sludge (PMS) is the rejected material generated from digester and paper machines in pulp and paper manufacturing. It is reported that one metric ton paper production gives rise to 40–50 kg dry sludge, and as much as 18.25 and 4–5 million tons of PMS are generated per year worldwide and in the U.S., respectively (de
This study utilized pulp and paper mill sludge as a carbon source to produce activated biochar adsorbents. The response surface methodology (RSM) application for predicting and optimizing the activated biochar preparation conditions was investigated. Biochars were prepared based on a Box–Behnken design (BBD) approach with three independent factors
2011/9/29/ · Background Ethanol production from paper sludge (PS) by simultaneous saccharification and fermentation (SSF) is considered to be the most appropriate way to process PS, as it contains negligible lignin. In this study, SSF was conducted using a cellulase produced from PS by the hypercellulase producer, Acremonium cellulolyticus C-1 for PS
2015/1/6/ · Paper mill sludge is a solid waste material composed of pulp residues and ash generated from pulping and paper making process. The carbohydrate portion of the sludges from Kraft/Recycle paper mill has chemical and physical characteristics similar to those of commercial wood pulp. Because of its high carbohydrate content and well-dispersed
2022/4/27/ · Paper Mill Sludge (PMS) is the organic residual obtained from different stages of the paper production process, including the selection, squeezing, screening, deinking, washing, refining, releasing color and bleaching processes and this sludge contains water, fiber, different organic compounds, several inorganic minerals and mineral fillers
Paper mill sludge (PS), a solid waste from pulp and paper industry, was investigated as a feedstock for acetone-butanol-ethanol (ABE) production by simultaneous saccharification and fermentation (SSF). ABE fermentation of paper sludge by Clostridium acetobutylicum required partial removal of ash in PS to enhance its enzymatic digestibility.

2020/9/15/ · Pulp and paper mill sludge is a waste generated from the pulp and paper industry and is generally characterised as aggregated losses from chemical and mechanical pulping, which is suspended in wastewater and has a fibrous texture (van Ewijk et al., 2018).Fig. 1 displays an abbreviated outline of the pulp and paper manufacturing process
2013/8/28/ · One advantage of using paper mill sludge is that it requires no pretreatment, so it can be directly subjected to enzymatic hydrolysis and/or fermentation (Kang et al. 2010;Shi et al. 2015), and a
