Phosphorus a Limited Resource - Closing the Loop

Join us in making more efficient use of the world’s limited and non-renewable phosphorus resources!

Better use of phosphorus as a resource is necessary because phosphorus is a critical and limited resource for the production of our food. This is also an important component in developing the circular economy with positive impacts on consumption, climate change and eutrophication of our waters.

Phosphorus is essential for agriculture and food production. At the same time phosphorus is a non-renewable resource and has no substitutes. About 90% of the global phosphorus mining production is used as fertilizer in food production and as global demand for food increases the need for phosphorus continues to grow. At the present increasing demand for phosphate rock we will deplete the world’s cheap and high quality reserves within 50-100 years leaving more expensive and lower quality reserves for the next generation. Phosphate rock reserves are located in only a very few countries in China and the US and mainly in Morocco/West Sahara (75% of the global reserves).

About 80% of the mined phosphorus is lost by the stage it is in the form of consumable food and this has major impacts on the amounts of P consumed in fertilizer and food production and the losses to the environment. Phosphorus is the principle cause for eutrophication of freshwater and the deterioration of surface water quality in rivers, lakes and coastal zones in much of Europe and around the world.

Phosphorus can be recovered and reused from both solid and liquid waste systems within certain economic and technical limits. In the Nordic countries we can contribute know how in using phosphorus more efficiently while also applying a circular economy perspective promoting P recovery within the EU and on the international agenda. The Nordic countries have a strong historical foundation in reuse and recycling when it comes to strategic focus, experience and cooperation including technology development and successful implementation. Through the Nordic Council of Ministers, this conference will explore and demonstrate the possibilities of more efficient and optimal use of the phosphorus resources.

With this conference we will create a meeting space for exchange of knowledge, best-practices and experience plus focus political attention to the local, national, regional and international levels.

10.00-10.20: The Magical Factory
By Ketil Stoknes, Lindum, Norway
The biogas plant is the central component of a "magic" ecosystem which makes possible real climate action and circular economy in the region. The "magic" project optimizes the use of nutrients through integrating a closed greenhouse system. The pathways of nitrogen and phosphorus will be illustrated.
