Pulp & Paper Indsustry Materials
Many paper mills have developed programs to identify beneficial use of materials generated on site, resulting in conservation of landfill space. For example:
- Waste water treatment residuals can be used as soil amendments to enhance crop productivity
- Wood ash is most commonly used in land application as a liming agent, and it also can supply plant nutrients such as calcium, phosphorus and potassium
- Lime mud is also utilized in land application as a liming agent. In addition to raising soil pH, lime mud can provide plant nutrients, especially phosphorus.
