CHICAGO, IL — La Rochette Venizel, a French-based biochemical producer, has made a lignin-based product that it says has many qualities: binder, emulsifier or dispersing agent. Called Novibond, a chemical agent obtained from processing lignin, the range of lignosulphate polymers produced results from the way in which the lignin is processed. During the heat treatment of wood, the extracted lignin is sulphonated, resulting in it becoming water-soluble, and thereby creating a complex polymer, lignosulphate. Simply put, various products come about from the conversion of such salts as calcium, ammonium, sodium and magnesium and, as well, on the reduction of sugars, or polymerization. Each derivative has a particular characteristic, making it suitable for various uses. For example, as a dispersant, it retards the deposit of insolubles in aqueous solutions. This dispersing property applies to paints, refractory materials and water treatment.

Stora Enso Oyj, Europe’s top paper producer, said it will sell power plants worth two billion euros (about $3.2-billion) to help finance a drive to overtake International Paper Co. as the world’s largest forest products company.

The APE Research Council of Washington, DC, has released a new study whose central finding is that laboratory rats exposed to low doses of octylphenol (OP) suffered no adverse effects to their reproductive systems. “The study casts serious doubt on the results of some previous studies on OP and on the theory that current toxicity testing is inadequate to address affects from low doses of endocrine active chemicals,” the APE said. OP is used to make octylphenol ethoxylate (OPE) surfactants, a class of alkylphenol ethoxylate (APE) compounds.

MODERNIZATION: KRUGER INVESTS $51M ON QUEBEC MILL

MONTREAL, QC — Kruger plans to spend $51 million to update its 640-t/d newsprint mill in Bromptonville, QC. The project is financed by Investissement Qubec, a provincial government body. Among other things, the 14-month modernization project will double the capacity of the deinking facility, which dates to 1992 — to 140 000 tonnes from 70 000 tonnes. “The increase in capacity of the deinking plant will allow an increase in the percentage of recycled fibres contained in the paper manufactured at the Trois-Rivires mill and the Bromptonville mill,” the company said in a press release. Over the last decade, Kruger has invested more than $160 million in the mill. The company has also noted that the current project will create some jobs, adding to the 470 employees who work at Bromptonville.
