International Paper's Androscoggin Mill Waste Minimization Program, 1992 Environmental Conference Proceedings
International Paper’s Androscoggin Mill has adopted a five-step hierarchy in their attempt to minimize waste to the on-site landfill: Reduce the amount of waste generated in the mill; reuse what can be used in-house; recycle material to sources outside the mill; incinerate combustibles; and use the landfill as a last resort.
In keeping with that hierarchy, the mill has addressed sludge, knots and screenings, flume grit, lime mud, and general paper mill trash. Through reduction, reuse, recycling, and incineration, the mill has reduced solid waste to the landfill by 92% in the past several years.
