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.
2008/2/1/ · Such an aerobic FF regime has been applied to treat organic waste residuals and wastewaters (e.g., olive oil mill wastewaters, primary and secondary sludges, paper mill effluents, molasses, food
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
2023/8/21/ · Polyaluminum chloride (PAC) is used widely and increasingly in wastewater treatment plants, resulting in its inevitably high production in sludge. Previous studies have indicated that the production of short-chain fatty acids (SCFAs) is inhibited by the existence of PAC in sludge anaerobic fermentation, so it is necessary to study how to promote sludge
2020/3/15/ · The influences of flow patterns (mixed-flow and plug-flow) and fermentation pretreatment on aerobic granular sludge (AGS) formation with various substrate availability levels were investigated by running four identical laboratory-scale sequencing batch reactors (R1-R4), comparing two anaerobic feeding strategies and three
2007/4/1/ · bic/aerobic treatment system effluent, 5–10 mg/L, compared to 50–85 mg/L in the AST system only. Similar. improvement was observed in terms of the organic matter removal: 220–250 mg/L vs. 80
2023/11/1/ · The objective of this study was to investigate the influence of aerobic sludge types and SRTs on the enrichment of MMCs rich in PHA-synthesizing bacteria treating LA fermentation broth. Two types of aerobic sludge (pig farm sludge and municipal sludge) and two different SRTs (2 and 8 days) were used in the experiments. The effect on PHA

2014/2/4/ · The Swedish Energy Agency, Linköping University and participating pulp and paper mills are funding the continuation of this research with SEK 14.8 m over a two-year period.
2024/4/30/ · The relevant studies will provide new sights into sludge fermentation and guidance for sludge disposal. We are inviting research papers and reviews about novel insights on sludge fermentation. The aim of this Special Issue is to provide an insight into the latest findings of sludge fermentation, including the biologically volatile fatty acids
2022/5/1/ · With regard to nutrient supply, paper sludge is considered a suitable co-substrate for fermentation in anaerobic digestion MBTs. The higher heating values (HHV)
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
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
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 dewatered and discharged into landfills or land spread at a cost to the mill; creating large
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
