Nutrient Recyclates for Organic Farming (nurec4org)

Examination of phosphorus-containing recyclates in terms of their acceptance and approval

The aim of organic farming is to minimise the consumption of finite resources and to concentrate on “Circular Economy”. Closing regional nutrient cycles is therefore one of the corner stones to ensure sustainable agriculture.

Nutrients recovered from bio-based materials and wastes offer the opportunity to promote the transformation towards sustainable agriculture and circular economy. So far, nutrient cycles are not sufficiently closed, be it in conventional or organic agriculture. This accounts in particular for the case of phosphorus. The only allowed mineral source to compensate phosphorus losses from organic farming systems is fossil based phosphate rock with its arguable fertilising efficiency and potential contamination with the toxic elements Cadmium and Uranium.

The project “nurec4org” (Nutrient recyclates for organic farming) examines to what extent phosphorus-containing products, which can be obtained through currently available recovery and recycling methods, will be acceptable and approved for organic farming. The aim is to introduce the scientific findings to the corresponding German and European approval bodies and to finally transfer them to the regulations for organic farming (EC/889/2008). Important stakeholders like farmers, trading companies and scientific institutions are involved in the investigations.

Activities

  1. Intensive and interactive stakeholder dialogue to define criteria for acceptance
  2. Assessment of the market potential P recyclates in organic farming
  3. Characterisation of quality of suitable recyclate
  4. Application of organic farming assessment methods adapted to specific organic farming requirements for both, products and processes (LCA, risk assessment)

It is possible to recover fertilizers during wastewater and sewage sludge treatment. Amongst other things,  the production of clean, low-emission and plant available struvite is possible. For this nutrient recyclate, the use in organic farming is intended.
The video was supported by the German Federal Environmental Foundation (DBU) as part of the “nurec4org” project.

The Project is finished. Download of report (in German only)  here.

  • Dünger in Kläranlagen statt in Bergwerken gewinnen

    Eine Stiftung erkennt in Struvit aus Abwasser die Phosphorversorgung der Zukunft. Ein Öko-Bauer sieht in dem Material nur eine Zwischenlösung.
  • Studie zur Phosphat-Versorgung im Ökolandbau erschienen

    Gute Aussichten für den Ökolandbau und für Kläranlagenbetreiber: Das Düngen mit Struvit, einem aus Abwasser zurückgewonnenen phosphathaltigen Mineral, stößt im Ökosektor auf Akzeptanz.
  • Endlich Phosphor aus Abwasser recyceln!

    Klärschlamm auf Biofeldern? Für viele ist das immer noch undenkbar. Dabei düngen einige Nährstoffrezyklate besser und sind weniger schadstoffbelastet als das bisher verwendete Rohphosphat.
  • Projetkstudie ergibt: Für den Ökolandbau ist Struvit im Vergleich zu verschiedenen möglichen Phosphat-Produkten aus Abwasser oder Klärschlammasche die bestmögliche recycelte Düngealternative zu Rohphosphat.
  • Phosphatversorgung im Ökolandbau langfristig sicherstellen

    Gute Aussichten für den Ökolandbau und für Kläranlagenbetreiber: Das Düngen mit Struvit, einem aus Abwasser zurückgewonnenen phosphathaltigen Mineral, stößt im Ökosektor auf Akzeptanz.
  • Phosphorus recycling: Next Generation Fertilisers

  • EU Fertilizer Regulation is intended to create fair conditions for recycled P-recyclates.
