In a unique project, universities and companies collaborate to better utilize industrial byproducts and replace finite resources with renewable ones. The goal is to further develop a new fertilizer that closes the loop within the forest ecosystem, creating value for both the market and the environment.
The majority of fertilizers used in the forestry industry consist of finite resources and result in significant carbon dioxide emissions. The RE:Source project “Forest Resources in Circular Systems” is currently working on developing a new circular fertilizer product. They utilize sludge from pulp mills, transforming it into a valuable resource. Leading industry players are behind this initiative, ready to develop, test, and commercialize this innovative type of fertilizer.
The nutrient-rich biochar developed by participating stakeholders is based on byproducts from the paper and pulp industry. Nutrients and minerals absorbed by trees during their growth accumulate in the sludge and ash at the pulp mills. Previous research projects at Karlstad University have demonstrated that these byproducts can serve as the foundation for an effective and natural fertilizer for growing forests.
