Paper Giant Integrates Biomass into Operations

Paper manufacturer Kruger was given the green light to proceed with construction of its 23 MW biomass cogeneration plant in the company’s Brompton mill, located in the Eastern Townships of Quebec. Developed in response to Hydro-Quebec-Distribution’s mid 2003 call for tenders, the plant will supply 100 MW of electricity generated from biomass.

In addition to creating a market for wood waste, the facility will consolidate almost 500 jobs. The plant has been in operation since 1903 and produces 840 tons of newsprint daily. In March 2004, Kruger established the Kruger Energy Group to achieve its growth objectives in the energy sector. This project is the company’s latest foray into renewable energy technologies that can be integrated with its paper manufacturing operation. The project will be completed in two stages. The first will entail the installation of a boiler to burn paper mill sludge, bark and other wood residues. In the second phase, a steam turbine will be installed downstream from the boiler to generate electricity and supply the steam required for mill operations. The company plans to take the necessary measures to mitigate noise, odor, steam, and visual impacts caused by daily operations for residents living nearby. “In addition to the $85-million investment,” Jacques Gauthier, Senior Vice President and Chief Operating Officer of Kruger’s Energy Group, “the biomass cogeneration project will allow the company to maintain the competitiveness of its Brompton mill through reduced production costs.” Environmental benefits include an annual reduction in greenhouse gases equivalent to removing 18,000 vehicles from the road; reduction in future landfilling of paper mill sludge, bark, and particle waste; reduction in the risk of leachate contamination as a result of reduced landfilling of bark; reduction in fossil fuel consumption; and an overall improvement in air quality.
