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
2014/11/15/ · Conclusions. Anaerobic digestion of pulp and paper mill waste at full-scale is currently confined to the treatment of a few selected types of effluent, and the resulting biogas is commonly burned to produce steam and electricity. Full-scale digesters for mill-derived sludges (biosolids) are almost non-existent.
2021/5/15/ · 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
2010/1/23/ · In this study, two different types of paper mill sludges, primary sludge and recycle sludge, were evaluated as a feedstock for bioconversion to ethanol. The sludges
2023/8/20/ · A sustainable industrial future involves the exploitation of renewable resources to obtain a wide diversity of products and energy and the decrease of waste generation. Primary sludge (PS) from pulp and paper mills is a lignocellulosic residue mainly consisting of cellulose and hemicelluloses that can be converted to bioethanol. In the
2020/9/8/ · Paper mill sludge (PMS) solids are predominantly comprised of cellulosic fibers and fillers rejected during the pulping or paper making process. Most sludges are
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
(46.7 wt%, Table 1), and was termed high ash paper waste sludge (HAPWS), and was supplied by a recycled tissue paper mill, Kimberly Clark Enstra. The third type of PWS had a medium AC (20.5 wt%, Table 1) and was termed medium ash paper waste sludge (MAPWS), and was supplied by a recycled corrugated cardboard mill, Mpact Springs.
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
2013/11/1/ · Earlier, Lin et al. [33] obtained a hydrogen yield of 64.5 mL/g VS of hydrogen from mesophilic co-digestion of pulp and paper mill sludge and food waste, where the VS of the pulp and paper mill
The primary paper sludge (PS) was collected from the primary wastewater clarifier unit of a Boise Paper Company kraft paper mill (Jackson, AL, USA). The consistency of the sludge slurry before the clarifier was between 0.5 and 3.0%. The consistency of sludge sample after the clarifier was around 20%. The PS was washed
2021/1/22/ · 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
Characterization and fermentation of waste paper sludge for bioethanol production by Sonja Boshoff Thesis presented in partial fulfilment of the requirements for the degree of Paper sludge samples from various paper and pulp mills in South Africa were collected and characterized into categories according to chemical
2021/4/29/ · The mill sludge accounts for the main waste from pulp and recycled paper production. Pulp and paper mill sludge is an organic residual generated from wastewater
