2016/1/1/ · Simultaneous saccharification and fermentation (SSF) of de-ashed paper mill sludge, Avicel and alkali-pretreated switchgrass. SSF of paper mill sludge was performed at 36 °C and 150 rpm in a 125 mL serum bottle containing 50 mL of P2 medium with 3.8–7.4% of PS7. Anaerobic condition was developed by sparging nitrogen gas into the

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
2015/6/3/ · 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 ).
2022/4/1/ · Pulp and paper mills generate large quantities of waste in the form of cellulose-rich paper mill sludge (PMS), which is commonly disposed of in landfills or by incineration. The utilization of this waste is commonly inundated with low product yields due to high ash content, which results in decreased enzymatic hydrolysis ( Tawalbeh et al., 2021 ).
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
2024/5/2/ · A pioneering solution has been developed to convert cellulose fibre-rich waste from pulp and paper mill operations into ethanol using a specialised fermentation process. Ethanol is a versatile starting material that finds diverse application in the production of industrial chemicals, bio-based plastics and sustainable aviation fuel. The solution by 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
2014/11/20/ · 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
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.
2024/4/19/ · Paper sludge (PS) from paper mills has a significant potential for bioethanol production. In this study, waste-paper-containing PS is used as the raw material for bioethanol production because the annual waste paper utilization rate has increased globally. Although PS does not require delignification, the antiseptics and deinking agents in waste
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
2021/5/20/ · 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
2023/12/1/ · Two different types of paper mill sludges, primary sludge and recycle sludge, were evaluated as a feedstock for bioconversion to ethanol and the ash was partially neutralized by the acids produced from the SSCF and SSF and acted as a buffer to stabilize the pH during fermentation. Solid-State Fermentation Systems—An Overview. C.
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 …
