\"SODRA_300x200\"<\/a>S\u00f6dra has developed a bio-ash that comprises nutrients from forest raw materials and can be produced at the company\u2019s own mills. The material will be used to return nutrients to the forest in order to close the ecosystem and ensure long-term production capacity.<\/p>\n

 
\nWhen extracting raw materials from the forest, the land is also extracted of nutrients. This usually only occurs to a limited degree since nutrients are primarily found in branches and needles, which are left behind on the ground. However, when branches and treetops \u2013 which are used in the production of bioenergy \u2013 are harvested, the amount of nutrients extracted increases. It is for this reason that S\u00f6dra is now developing a service to return nutrients to the forest in the form of bio-ash after harvesting branches and treetops.<\/p>\n

 
\nProject Manager, Hedvig Johansson says, \u201cThere are currently no signs of nutrient depletion, but we must think about the long term and ensure we have a system in place that will enable nutrients to be returned to the forest for many years to come. Research suggests that \u2013 if executed effectively \u2013 returning nutrients to healthy forest land could result in increased forest growth for at least ten years after the bio-ash is spread. On fertile land, this could mean an additional 15 m\u00b3fo per hectare.\u201d<\/p>\n

 
\nAt the pulp mill in M\u00f6nster\u00e5s, S\u00f6dra has developed its own spreadable ash mix, which has been approved by the Swedish Forest Agency as a means of returning nutrients to the forest. The bio-ash is produced by mixing the ash from the pulp mill\u2019s bark boiler with nutrients extracted from wood raw material in the digester. S\u00f6dra\u2019s bio-ash contains nutrients such as magnesium and potassium as well as a high proportion of calcium, which helps to achieve a lower rate of acidification in the forest.<\/p>\n

 
\nSo far, S\u00f6dra has spread this newly developed bio-ash on 600 hectares of member forest land in the Sweden\u2019s eastern Sm\u00e5land region, achieving a positive result. The initiative is now being scaled up and the bio-ash will be spread on approximately 1,200 hectares of forest land by autumn 2017.<\/p>\n

 
\nAccording to Hedvig Johansson, S\u00f6dra has all the pieces in place to soon be able offer an effective and cost-efficient service for nutrient recycling.<\/p>\n

 
\nJohansson adds, \u201cWe have a complete chain in place \u2013 from the forest to industry and back to the forest \u2013 and a clean and effective production process. This is a true forestry ecosystem. The challenge now is to scale up the system for all of our forest owners.\u201d<\/p>\n
