Shortcutting the Nitrogen Cycle

We seem to have a love-hate relationship with organic nitrogen: much needed as a macronutrient for crop growth in agriculture, when present in natural areas at too high concentrations it can lead to loss of biodiversity. The production of ammonia based fertilizers from inert nitrogen gas (N2) is responsible for about 1 to 2% of the worldwide energy consumption. The degradation of organic nitrogen in wastewater treatment facilities contributes heavily to the overall central wastewater treatment plant (WWTP) costs. Shortcutting this human-driven part of the nitrogen cycle therefore provides an enticing perspective, and that’s what the N.E.W.B.I.E.S. project is all about!

As part of the project finalization, the results obtained over the complete project duration have been summarized in non-expert readable form. Click here to download the Laymens report
PP#9: Preliminary results on leachate

PP#9: Preliminary results on leachate

The first analytical results have been analysed for the leachate scenario and are presented in the attached report. As expected the high conductivity of the wastewater and relatively large sodium content caused inefficiencies that we hope to solve in the second and last pilot leg.
PP#8: Last testing site: pilot commissioning on Landfill Leachate

PP#8: Last testing site: pilot commissioning on Landfill Leachate

Time has come for the pilot to move to it's last test site within the NEWBIES project: the Landfill facility of Indaver in Nieuwdorp, Zeeland. Here it will treat the leachate that percolates through the landfills. A challenging wastewater, that compared to previous sites contains elevated salt concentrations and humics. Commissioning of the pilot went smoother than ever though!
PP#7: Second results on treatment of urine

PP#7: Second results on treatment of urine

The full experimental scheme of process characterization conditions on urine has been finished and preliminary results are reported, with some analytical data not available yet. Based on the obtained results, a most favorable combination of current density, operational mode, feed control method and CIP parameters is defined. We're looking forward how these conditions will turn out to perform on the longer run!


Responsible for the design, construction and operation of the pilot installation, W&F Technologies enables the market uptake of the N.E.W.B.I.E.S. technology.

Based in Girona, Spain, the Catalan Institute for Water Research provides scientific excellence of the integrated water cycle. Within the N.E.W.B.I.E.S. project, ICRA hosts the testing of the technology on digestate reject water

Evides Water provides drinking water to 2.5 million people in the southern provinces of the Netherlands. Moreover they provide industrial water services to a variety of large industrial companies in the Netherlands, Belgium and Germany. Evides partners with N.E.W.B.I.E.S. to explore its ability to remove nitrogen from landfill leachate.
