Unique landfill options spurred by employing mill solid wastes

Paper and pulp mills can solve their waste management problems by taking into account physical characteristics of waste materials when building landfills. The mills need to evaluate the waste's subsurface hydrologic and geotechnical conditions, consider specialized construction techniques for unstable surfaces, and use wastes as construction materials when building solid waste landfills. An impermeable cap built over landfills can prevent migration of waste materials and diminish pollution hazards.
LARGE EARTHEN IMPOUNDMENTS, ASH ponds, and landfills are common at most pulp and paper mills. As production levels and regulatory requirements have changed, many mills have encountered difficulties with these [...]
