Absorbable Organic Halide (AOX) Reduction in Elemental Chlorine-Free (ECF) Bleaching of Bagasse Pulp from the Addition of Sodium Sulphide

BioResources, 2015
A laboratory investigation was developed to confirm and to quantify the reductions in absorbable organic halide (AOX) discharge when sodium sulphide was added during elemental chlorine-free (ECF) bleaching of sugarcane bagasse pulp.

Aerobic degradation of 2,4,6-TCP content in ECF bleached effluent

Environment International, 2003
Elemental chlorine-free (ECF) bleach effluents from kraft mill are characterised by: a chemical organic demand/biological organic demand (COD/BOD(5)) ratio of 4, chlorophenol content with low chlorine substitution, and toxicity. The effect of increasing the concentration of 2,4,6-trichlorophenol (2,4,6-TCP) content in ECF bleaching sequence effluent on

An ER–microtubule bridge: Reticulon 17 links microtubules with ER network organisation in plants

The Plant Journal, Volume 127, Issue 1, July 2026.
Significance Statement Endoplasmic reticulum (ER) organisation underpins key processes in plant growth, secretion, and stress responses, yet how the ER connects to the cytoskeleton remains unclear. We identify Arabidopsis Reticulon 17 (RTN17) as an atypical reticulon that links the ER to microtubules and recruits the ER fusogen RHD3 to curved ER ...

Preparation and characterization of fluff from bamboo as source of fibre for the production of hygiene products

Advances in Bamboo Science
This work explores the utilization of the bamboo Dendrocalamus strictus in place of softwood for the production of fluff. Unbleached kraft bamboo pulp was prepared using Kraft pulping.

Color and COD Removal From ECF Effluent by Airlift Reactor With Immobilized Lentinus edodes

Chemical Engineering &Technology, Volume 49, Issue 5, May 2026.
Airlift bioreactor treating ECF bleaching effluent with Lentinus edodes immobilized on polystyrene fibers achieved up to 48% color and 41% COD removal. Under optimized aeration (300 mL/min) and HRT (78 h) without glucose, COD removal remained stable for 15 days, supporting a low‐input, enzyme‐driven strategy for pulp‐and‐paper wastewater. ABSTRACT This

The link between kraft cooking and bleaching : influence on ECF bleachabiblity and bleaching effluent parameters [PDF]

, 2004
The link between kraft cooking and bleaching was investigated, with the focus on how cooking kappa number, cooking conditions and pre-bleaching stages influence ECF bleachability and environmental parameters in the bleaching effluent.

The Experience of ECF Bleaching Plant Operation

JAPAN TAPPI JOURNAL, 2000
Hokuetsu Paper Niigata Mill started up in June 1998 its third coated paper machine (PM8) with a capacity of 240, 000tpy. For the purpose of not having to purchase as much market pulp for this machine and other upgraded machines, the increase of pulp production capacity and the modernization of the plant were planned are carried out before the machine's

Ultrafast and Coherent Dynamics in a Solvent Switchable “Pink Box” Perylene Diimide Dimer

Angewandte Chemie, Volume 136, Issue 39, September 23, 2024.
Ultrafast coherent multidimensional spectroscopy probes photoinduced dynamics in a covalent perylene diimide (PDI) dimer exhibiting solvent‐controlled on/off excitonic coupling. Excitonic coupling leads to ultrafast excimer formation. The coupling dependent population and vibrationally coherent dynamics in the two cases are measured and discussed in ...
