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
2016/3/1/ · Pulp and paper production requires large amounts of water, ranging between 15 and 100 m 3 Mg −1 dry pulp, used as reaction media and wash water (Ackermann et al., 1999, IPPC, 2001, CANMET, 2005, Ashrafi et al., 2015), which effluent needs to be treated before being released to the environment.PPMS is the organic residual material remaining

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
2022/4/1/ · 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 ...
This study utilized pulp and paper mill sludge as a carbon source to produce activated biochar adsorbents. The response surface methodology (RSM) application for predicting and optimizing the activated biochar preparation conditions was investigated. Biochars were prepared based on a Box–Behnken design (BBD) approach with three independent factors
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.
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.
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
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
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
2019/4/1/ · The best fermentation conditions were fermentation time of 5.72 days, initial material liquid ratio of 1:4.58, initial pH of 6.32 and fermentation temperature of 28.8 ℃, with a filter paper
Paper sludge (PS) produced from the paper industry has mainly cellulosic fibres, with calcium carbonate and some ink generated during the pulping mechanism 展开
2021/8/11/ · Pulp and paper mill sludge (PPMS) represents a large part of the industrial waste and contains a high portion of the organic matter (Elliott and Mahmood, 2012a).Sludge waste is produced from both virgin and recycled paper production processes (Simão et al. 2018).However, this substrate is usually undesirable and needs to be treated or disposed of
