Promoting pulp and paper mill material circularity: functionalised organic-inorganic cellulosic mulch films
Water scarcity, fertiliser run-off, and weeds competing for resources reduce forestry and agricultural productivity. Conventionally, fossil-fuel-based synthetic mulch films have been used to mitigate soil water loss, as a matrix for the slow-release of fertiliser, and for UV-vis light blocking to …

Biochemical Studies on Enzymatic Treatment of Pulp and Paper Mill Biosludge and Polymeric Lignin
… is just becoming popular for the treatment of pulp and paper mill effluents. However, hydrolysis of complex organic matter represents the rate-limiting step of anaerobic digestion. Hence, this project is focused on improving the anaerobic digestibility of pulp and paper mill biosludge using …

Identification and analysis of extractable organic compounds present in pulp and paper mill effluent
… present in the effluent streams of a New Zealand pulp and paper mill have been investigated. Nearly 200 compounds were detected, of which 170 were identified. Most of the compounds are released during mill operations. Some of the compounds detected in treatment system samples arise from the …

Utilization potential for pulp and paper of southern pine harvested from beetle infested forests
… the following conclusions may be drawn: (1) Pulp yield is not affected significantly by allowing the dead trees to remain on the stump for extended periods of time (three years). (2) Canadian Standard Freeness increases significantly at high beating times as wood deteriorates (up to 24 …

Characterisation and fate of bleached kraft mill effluents from a New Zealand pulp and paper mill
… discharges from the Kinleith mill, a New Zealand integrated bleached kraft pulp and paper mill, were characterised and their treatability assessed. The chlorination stage bleaching effluents from the mill’s second bleach plant [(C30D70)EoDED sequence] contained a group of novel chlorinated …

Promoting material circularity in pulp and paper mills: organic-inorganic cellulosic composites for slow-release of nutrients
The pulp and paper industry generates large quantities of waste, while the forestry sector experiences economic and environmental challenges with commercial fertilisers. Slow/controlled-release fertilisers (SCRFs) offer an opportunity to repurpose waste-stream materials and improve nutrient …

Evaluation of membrane filtration for treatment of black liquor in small-scale pulp and paper mills in India
… a strongly polluting byproduct from the kraft pulping process in pulp and paper mills, is traditionally treated by being passed through multiple effect evaporators and burned in a recovery boiler to produce energy and recover chemicals. However, the traditional treatment of black liquor is not …

Application of Ozone in Dissolved Air Flotation (DAF) for Enhanced Removal of TOC and Suspended Solids in Pulp and Paper Wastewaters
Pulp and paper mills are one of the top consumers of water related to industrial manufacturing, which ultimately leads to a large volume of heavily contaminated wastewater. This discharged effluent can have a harmful effect on the receiving aquatic environment and cause further ramifications …

An assessment of endocrine disrupting potential of a New Zealand pulp and paper mill effluent using rainbow trout Oncorhynchus mykiss and mosquitofish Gambusia affinis
… the effects of a modern mixed thermo-mechanical pulp/bleached kraft (TMP/BK) mill effluent on potential reproductive-endocrine impacts on two fish species, rainbow trout and mosquitofish using a combined approach of laboratory and on-site mesocosm exposures. Rainbow trout Oncorhynchus mykiss were …

The anti-estrogenic and liver metabolic effects of DHAA in rainbow trout (oncorhynchus mykiss)
… acid (DHAA), a resin acid present in pulp and paper mills, may have anti-estrogenic effects in fish. A chronic-exposure toxicity experiment using immature rainbow trout (Oncorhynchus mykiss) was conducted in order to assess the endocrine disrupting and liver metabolic effects of the …
