2021/4/29/ · A wide variety of biomass is available all around the world. Most of the biomass exists as a by-product from manufacturing industries. Pulp and paper mills contribute to a higher amount of these biomasses mostly discarded in the landfills creating an environmental burden. Biomasses from other sources have been used to produce different
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. Fermentation was carried out in a shaking water bath at a temperature of 37.5 °C and 80 rpm until gas production ceased. Optimal C/N ratios of 50, 30, and 50 were ...
2021/6/15/ · 1. Introduction. Paper mill sludge (PMS) is the rejected material generated from digester and paper machines in pulp and paper manufacturing. It is reported that one metric ton paper production gives rise to 40–50 kg dry sludge, and as much as 18.25 and 4–5 million tons of PMS are generated per year worldwide and in the U.S., respectively (de
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
2016/3/1/ · The pulp and paper industry produces large quantities of paper waste sludge (PWS), typically 100 to 500 kg PWS per ton of paper, usually disposed of by landfill. This material has a high organic
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
2018/4/1/ · The pulp and paper making process produces about 300–350 million tons of paper mill sludge (PMS) every year which is a huge volume of industrial waste. This waste stream is an economic burden and also an environmental concern since the majority of the PMS is disposed of by landfill (Negi and Suthar, 2013, Gurram et al., 2015). PMS contains up
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
(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.
2014/10/27/ · With Chamber press, possible achievable DSC varies between 30 and 50 %. Voith Paper has developed Thune which is a new design of screw press used for dewatering pulp and paper mill sludge (Norli and Smedsrud 2006). The trial was conducted at the new Adolf Jass Schwarza mill at Rudolstadt Germany in 2005. The new screw press achieves
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
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
2024/1/26/ · 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 …
