Resolute Forest Products found a solution to divert waste from its operations through the spread of agricultural land. Some waste products that would otherwise be disposed of in landfills will be used to fertilize the soil on agricultural land, due to the richness of nutrients in organic waste such as dehydrated sludge and wood ash, which contain phosphorus and nitrogen, nutrients that help plant growth.
In 2020, 28% of the waste from Resolute’s pulp, paper and tissue mill was used beneficially for the land, such as paper production sludge that can be dehydrated, pressed and supplied to local farmers to apply to their land. crops.
The pulp and paper mill in Thunder Bay (Ontario) has distributed nearly 3,000 metric tons of wood ash produced by the biomass boiler to area farmers and continues to work with Lakehead University, developing datasets to demonstrate beneficial use of applications of mud and ash for agricultural fields. In the US, the Menominee recycled pulp mill (Michigan) and the Grenada (Mississippi) newsprint mill have been reusing bark boiler mud and ash, respectively, for spreading on land for several years.
By identifying alternative uses for the by-products, the company ends up minimizing waste and adding value to communities, contributing to the circular economy. Each factory worked with local contractors to supply nearby farms, testing and approving the soil.
