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
2024/2/1/ · Anaerobic fermentation is widely installed to recovery valuable resources and energy as CH 4 from waste activated sludge (WAS), and its implementation in developing countries is largely restricted by the slow hydrolysis, poor efficiency, and complicate inert components therein. In this study, enzyme-enhanced fermentation was conducted to
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
2017/8/1/ · In this study, hydrogen harvesting from fermentation of sugarcane bagasse (SCB) was promoted by maintaining synergism between sulfonated graphene (SGR) catalyst and paper mill sludge (PMS). The sulfonic acid (–SO 3 H) groups in the catalyst played a major role in destructing the β-1,4 glycosidic bonds of sugarcane bagasse, releasing readily
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
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
2024/1/26/ · This review explores circular economy principles in regard to ethanol production from paper-mill sludge. Environmental sustainability and renewability over fossil fuels make second generation ethanol an attractive energy source in a rapidly growing population and consumption world. Paper sludge (PS), a by-product of the pulp and paper
2016/7/1/ · Savings on paper sludge disposal cost consisted of two parts, namely land fill charges of R 705/dry ton and transport costs of R 174/dry ton (Nampak Tissue, 2011). The fermentation of paper sludge reduced disposal costs by 35.1%. The disposal cost reduction was calculated on 22 t/d unwashed paper sludge, which equates to 15 t/d washed sludge.
2004/2/1/ · Moreover earlier studies of invessel composting of paper mill sludge required long time for the composting process and varied between 121 days to 28 days (Jackson and Line, 1997;Das et al., 2001).
2013/11/1/ · However, only few studies were reported on hydrogen and methane production from more than one residue in co-fermentation, e.g. FW + pulp and paper sludge (Lin et al., 2013) and FW + waste
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
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.
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).
