The production of pulp and paper is a major industry in Wisconsin with many mills located along the Wisconsin River valley in north central Wisconsin. One of the leaders in this industry is Stora Enso North America (formerly Consolidated Papers, Inc.) with their state headquarters in Wisconsin Rapids. As a consequence of producing a variety of finished paper products, a significant amount of byproduct material is generated. Prior to the mid-1980’s most of this byproduct material was land-filled. Consolidated Papers Inc., began a research program in the 1970’s to look at various land spreading options, largely focusing on the sandy textured soils which are predominant in the area. The development of a land spreading program has the dual benefit of reducing the need for costly landfill space and recycle valuable nutrients and organic matter into local agricultural fields. This will have a positive economic and environmental impact on the industry, their clients and the community.
