2024/1/2/ · Paper mill sludge (PMS) mitigated inhibitory effect of furfural in black liquor (BL). • PMS improved H 2 yield from the BL by 8.3-folds and accounted for 2.1 mol/mol glucose.. e – eq transferred to H 2 was 9.3% in the PMS:BL, 7.4% in PMS, and 1.27% in BL.. Acinetobacter degrading furfural (6.1%) was abundant with PMS addition.. Bacilli (8.9%)
2020/9/15/ · Pulp and paper mill sludge is a waste generated from the pulp and paper industry and is generally characterised as aggregated losses from chemical and mechanical pulping, which is suspended in wastewater and has a fibrous texture (van Ewijk et al., 2018).Fig. 1 displays an abbreviated outline of the pulp and paper manufacturing process
1. Introduction. Paper mill sludge (PS) is a significant byproduct generated in the pulp and paper industry. With the increasing demand for paper and board products, the global annual production of PS exceeds 400 million tons (Feng et al., 2022).PS primarily consists of cellulose fibers, lignin, and inorganic fillers like CaCO 3 and Kaolin, thus it has a great potential for
2011/9/29/ · Background Ethanol production from paper sludge (PS) by simultaneous saccharification and fermentation (SSF) is considered to be the most appropriate way to process PS, as it contains negligible lignin. In this study, SSF was conducted using a cellulase produced from PS by the hypercellulase producer, Acremonium cellulolyticus C-1 for PS
2024/1/26/ · Due to the organic content, the landfilled paper mill sludge is subject to aerobic and anaerobic decay. Theoretically, when landfilling 1 ton of low-ash paper mill sludge (<30% ash), approximately 2.69 tons of CO 2 and 0.24 tons of CH 4 are released into the environment . SPS volumes are lower than those corresponding to the PS, since most of
2020/9/13/ · Paper mill sludge serves as a source of lignocellulosic biomass that can be used for bioethanol production and is classified as second-generation biofuel. Different
2022/4/27/ · Proper utilization of paper mills sludge by producing activated carbon not only reducing the volume of waste sludge to keeping our environment ecologically safe, but
2020/9/8/ · In this manuscript, we demonstrated that sludge from pulp and paper mills in the USA (a non-food feedstock) are a good source of sugars that can be successfully
ABSTRACT: This study utilized pulp and paper mill sludge as a carbon source to produce activated biochar adsorbents. The response surface methodology (RSM) application for
2024/5/10/ · Thus, with the rapid expansion of pulp and paper industry, large amount of pulp and paper mill sludge (PPMS) will be generated, as for 1 ton of paper produced, 50 to 600 kg of dry sludge will be generated (Ouadi et al., 2019). The pulp and paper processes can be divided into virgin fiber (e.g., wood, straw) pulp and paper processes and
2008/2/1/ · In the present study a three-step process for PHA production from a paper mill wastewater in activated sludge was investigated: (1) acidogenic fermentation for the conversion of organic matter to VFAs; (2) continuous flow activated sludge process for enrichment of PHA-producing organisms; and (3) batch experiments for PHA accumulation
2. Trends in paper mill sludge generation The pulp and paper industry produce over 304 m illion tons of paper per year. In 2005, soley in Europe, 99.3 million tons of paper was produced which generated 11 million tons of waste and represented 11 % residue in relationship to the total paper production. The
The paper sludge and paper crumble supplies are sourced locally from Kent paper mills and the demand for this organic fertiliser has grown significantly in recent years. Although paper waste was historically sent to landfill sites or incinerated, increased awareness of the detrimental impact on the environment has resulted in a considerable
