2013/1/18/ · This review describes the utilization of paper sludge (PS), which is waste from the pulp and paper industry. Its advantages make PS the cellulosic biomass with the most potential for bio-refinery research and applicable for industrial scale. Some of the grain based biofuels and chemicals have already been in commercial operation, including fuel
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
2020/9/13/ · Paper mill sludge, a solid by-product of the paper industry, is considered as a promising feedstock for bioethanol production, which helps in replacing fossil fuels and mitigating greenhouse gases. India is one among the fastest growing paper and pulp market in the world with over 10% growth rate in a year in per capita consumption, which is
2014/11/15/ · Conclusions. Anaerobic digestion of pulp and paper mill waste at full-scale is currently confined to the treatment of a few selected types of effluent, and the resulting biogas is commonly burned to produce steam and electricity. Full-scale digesters for mill-derived sludges (biosolids) are almost non-existent.
2020/4/1/ · 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
2024/4/26/ · 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.
2017/8/1/ · The use of [Cho][OAc] IL supplemented with dilute HCl will certainly achieve dual benefits of high sugar yield and low fermentation inhibitors production from paper mill sludge. In addition, Liu et al. [32] stated that combination of IL and diluted acid is acceptable from environmental point of view where the remaining portions of residual
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 (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).
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
USA Sludge matches the feed-rate to the demand. This is best understood from the point-of-view of “Value-to Value”. In other words, we strive to seed a proper amount of Revive complex into the fermenting tank, and after a 24-hour period, begin releasing the solution into the waste stream, attempting to match the demand.
2017/8/1/ · Paper mill sludge is promising primitive materials for production of biofuels. However, its structure is resistant to enzymatic saccharification as well as fermentation process. [ChO][OAc] IL/PMS ratio of 10% (w/w) catalyzed by 1% HCl (v/v) revealed robust ability for PMS dissolution and delignification.
2024/1/26/ · This waste-to-energy (WtE) technology for ethanol production is proposed as an alternative, aligning with circular economy concepts to maximize resource efficiency
Paper sludge with a high ash content has been reported to have an additional advantage for butanol fermentation, while other studies have found that kraft paper mill sludge requires a partial removal of ash to enhance its enzymatic digestibility in ABE fermentation using C. acetobutylicum (Yang et al. 2013; Gottumukkala et al. 2016; Guan et al
