2016/1/1/ · 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 sludge (PS) from the paper and pulp industry consists primarily of cellulose and ash and has significant potential for ethanol production. Thirty-seven PS samples from 11 South African paper and pulp mills exhibited large variation in chemical composition and resulting ethanol production. Simu
2020/2/1/ · The waste produced from pulp and paper industry is categorized in rejects such as pulping, bleaching, washing, primary sludge, and secondary sludge. These waste materials are potential pollutants of air, soil, and water ( Petra and Lindholm-Lehto, 2015 ).
2021/2/1/ · The rejects waste stream used in this study was obtained from a paper mill located in the Gauteng province of South Africa, utilising recycled fibre as feedstock. Rejects are primarily produced as a sludge from the various processing activities (pulping, screening, etc.) that occur before the paper machine and contain significant amounts of
2012/5/1/ · This work examined the simultaneous saccharification and fermentation (SSF) process for the biological conversion of pulp & paper sludge (PPS) and monosodium glutamate waste liquor (MGWL) into
2024/2/14/ · Managing industrial waste as recycled resources can save on raw feedstock costs, reduce reliance on primary resources, and reduce positive environmental impacts.
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
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
2014/8/28/ · Paper sludge is an attractive biomass source for the conversion to ethanol due to its low cost and the lack of severe pretreatment required. Four sludges from pulp and paper operations including both virgin kraft (VK) and recycled and deinking (RD) paper mills were analyzed. A fractionation process using a laboratory screen was utilized to produce a
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 (SSF) with and without accelerants. The enzymatic hydrolysis and fermentation were first evaluated, and the energy demand was 2.2 MJ/L of produced ethanol.
2021/6/15/ · High concentrations of cellulosic ethanol achieved by fed batch semi simultaneous saccharification and fermentation of waste-paper. Effect of pulp and paper mill sludge on the development of 17-year-old loblolly pine (Pinus taeda L.) trees in Southern Brazil. Forest Ecology and Management, Volume 422, 2018, pp. 179-189 ...
The wastes from pulp and paper mills are both of organic and inorganic types. Most of the biomass generated from pulp and paper mills is organic residues. Black liquor consists of 展开
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
2024/5/3/ · 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. The solution was announced
