(2013) earlier proposed that much of the equipment used in the pulp and paper mill manufacturing process, e.g., wood chipping, digesting, mechanical refining, and evaporation, can be used for pretreatment operations, since they may already be present in the prospective pulp mills. Paper sludge with a high ash content has been reported to have
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

2021/8/1/ · Experimental studies are conducted with streams from three different pulp and paper mills (virgin pulp mill (VP), corrugated recycling mill (CR), tissue printed recycling
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
2024/2/9/ · Paper sludge consists mainly of wet short cellulose fibers that are lost during papermaking and of residual chemicals used in the manufacturing process that remain dissolved in the water. Each ton of paper generates about 40–50 kg of dry sludge, of which 70% is primary sludge. Paper production, which exceeded 400 million tons globally in
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
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 ...

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
2012/10/14/ · Purpose This paper presents an assessment of the production of polyhydroxyalkanoates (PHA) in biomass sourced from wastewater treatment plants (WWTPs). The purpose was to examine both the potential for more generic utilization of waste activated sludge as biomass for PHA production and the quality of the polymers produced.
2014/11/27/ · Primary sludge is a lignocellulosic residue from pulp and paper mills consisting of cellulosic fibers and ash. However, the high ash content (35%, mainly CaCO 3) and pH value affect the enzymatic hydrolysis of cellulosic fibers.Several pretreatments were used to reduce the CaCO 3 content and to adjust the pH. Enzymatic hydrolysis of primary
