Introduction to Recycled Pulp

What is/are Recycled Pulp?

Recycled Pulp - In this work, we engineered CNF sheets from refined and homogenized industrial virgin pulp (BEK), industrial recycled pulp (DIP) and lab-scale recycled pulp (LRC). ^[1] 5, and 10 wt% of recycled pulp composite, respectively. ^[2] Mineral/MFC composites made with recycled pulp feedstocks were shown to offer at least equivalent strength aid performance to composites made using virgin fibers. ^[3] Discussion and Conclusion: In general, leaves and branches residue of Conocarpus compared to other lignocellulosic materials such as wheat straw and bagasse, which is widely used in the pulp and paper industry, due to qualitative properties reasons are not suitable in pure form for use in pulp and paper industries but are recommended to evaluation as the mixing with the recycled pulp. ^[4] For the sample with the higher hardwood share an increase in strength properties with increasing steam treatment severities could be observed and it was possible to produce test sheets with comparable compression strength to recycled pulp for industrial corrugated paperboard. ^[5] Eight contaminants were used to perform a surrogate contamination test to evaluate safety of the process for producing recycled pulp for adult paper diapers. ^[6] In comparison to the other pretreated CNF, due to is lower viscosity, applying periodate-oxidized CNF as size press significantly increased the mechanical properties of the papers fabricated from the recycled pulps. ^[7] Bleached chemi-thermomechanial pulp (BCTMP) and recycled pulps (R-NPM and R-CBB) both showed non-cellulosic molecules and rougher surfaces. ^[8] The present research aims to shed light on the effect of activated sludge (from a paper mill) and nanochitosan on the physical and strength properties of recycled pulp. ^[9] Anaerobic co-digestion of sludge from recycled pulp and paper industry (RPPS) with vinasse effluent from alcohol distilleries (VW) was performed under mesophilic conditions (37 °C) at laboratory scale, using one-liter continuous stirred tank reactors (CSTRs). ^[10] The recycled pulp was activated using aqueous sodium hydroxide and then followed by acid neutralization, prior to the direct dissolution in lithium chloride/N,N-dimethylacetamide (LiCl/DMAc) at 3 wt. ^[11] The aims of this study were to perform the anaerobic digestion of recycled pulp and paper sludge (RPPS) at laboratory scale, using a continuously stirred tank reactor (CSTR) digester, to determine the methane yield of this type of waste, and to control the physico-chemical parameters to maintain its stability during the experiment. ^[12] This work focused on the performance of a continuous pilot subsurface flow (SSF) system of constructed wetlands in removing chemical oxygen demand (COD) representing organic carbon, colour and suspended solids from recycled pulp and paper mill under 5-day hydraulic retention time (HRT) for 95 days. ^[13] The present study was conducted to modify kaolin clay by coating cationic starches, maize and tapioca, aimed at effective incorporation into recycled pulp fibers. ^[14] This study deals with production of pulp and paper from waste banana pseudo stem and comparison with recycled pulp used for paper making. ^[15] Anaerobic treatment of wastewater from recycled pulp and paper industry in Morocco was tested using a laboratory-scale anaerobic biofilm digester that operated under mesophilic conditions over a 70-day. ^[16] The anaerobic digestion (AD) experiment for recycled pulp and paper sludge (RPPS) was carried out by a CSTR digester “Continious Stirred Tank Reactor” under mesophilic conditions (37 °C) at laboratory scale. ^[17] This laboratory handsheet and Fourdrinier pilot paper machine study examine the suitability of willow as a commercial hardwood pulp replacement including utilizing recycled pulp for paper production. ^[18] Handsheets were prepared with disintegrated recycled pulp and different amounts of CNF using a conventional three-component retention system. ^[19]
