About Nymphe

Nymphe is a four years European project dedicated to tackling environmental pollution by developing innovative bioremediation solutions.

The ambition is to remove multiple pollutants (such as microplastics and pesticides in the agricultural soil, and chlorinated solvents and petroleum hydrocarbon in groundwater and sediments in the industrial area) from different contaminated sites in Europe. Nymphe’s actions will improve the ecological quality and health of soils and waters. Our nature-based, low-energy and low-chemical solutions to eliminate pollutants will contribute to the expected outcomes of the EU Zero Pollution Action Plan.

The Nymphe Story

In Greek mythology, nymphs were spirits linked to springs, mountains, and forests: personifications of nature's vital forces and the balance of ecosystems. In biology, we speak of nymphs to describe insects in an immature stage before they transform into fully functional adults through metamorphosis. 

Nymphe project (New system-driven bioremediation of polluted habitats and environment) combines both meanings. It aims to develop biotechnological approaches that push natural ecosystems to transform and revitalize themselves, becoming capable of repairing the damage inflicted by human activity. Nymphe will contribute to the expected results of the European Union's Zero Pollution Action Plan staying in line with the European Green Deal.

Why bioremediation? 

Bioremediation is a more sustainable alternative to standard remediation options like burying polluted soils in landfills or chemical remediation that increases the health risk for workers. Unlike these conventional physicochemical remediation processes, which can be disruptive, bioremediation is less intrusive and can facilitate the remediation of environmental impacts without damaging delicate ecosystems.

What are our goals?

ikona 1.png

To develop bioremediation systems consisting of multiple enzymes,  micro- and macroorganisms.

ikona 2.png

To assess the strategies from technical, environmental, economic, and societal perspectives for the revitalization of polluted environments.

ikona 3.png

To introduce them at four pilot sites

The pilot sites

To prove the bioremediation efficiency, Nymphe will reimplement the assembled systems of biologics in four deeply contaminated sites and one site used as facility enabling tests with bioengineered biologics under confined conditions.

The pollutants that will be removed from the contaminated matrices are characteristic of each matrix, e.g., agricultural soil contaminated with microplastics and pesticides.

In addition, areas surrounding the sites (water resources, woodlands, agricultural activities) have been documented to frame the methodology for the ecological assessment in the standards of Natura 2000.

NYMPHE mapa.png
  • Industrial site - Ferrara Province, Italy

Contamination: Soil, GW, and aquifer sediments of the site are contaminated with Petroleum Hydrocarbons (PHC), chlorinated aliphatic hydrocarbons (CAH) and heavy metals (HM). 

The site is a chemical multi-company Eni Rewind S.

p. A. The company will carry out in-depth sampling, shipping samples to partners, and supervising site tests. 

  • Hyporheic zone (HZ) - Erpe river, Hoppegarten, Germany

The site in the river Erpe is composed of 60-80% of treated wastewater discharged by the municipal Wastewater Treatment Plant Münchehofe. 

Contamination: More than 100 organic pollutants (pharmaceuticals+metabolites) are routinely detected in surface water and hyporheic zone (HZ) sediments, including guanyl urea and ibuprofen. IGB will support sampling, analyses, and ex-situ and in-situ experiments in the HZ. 

  • Agricultural field - Falassarna, Western Crete, Greece

Contamination: This area was historically used to produce tomatoes and cucumbers, but now the soil is contaminated with microplastics, pesticides, and microbial-based pesticides used for organic farming. 

CHQ will work with regional cooperatives of tomato producers to identify the areas (next to an operating greenhouse) for the ex-situ bioremediation of microplastics and pesticides. Samples will also be collected, analysed for microplastics and pesticides, and distributed to partners. 

  • Facility for "confined use" of bioengineered biologics  - Leopoldov, Slovak Republic

The design of reactors for confined application of bioengineered biologics will be set according to instructions of the Slovakian Ministry of the Environment. 

The transport of the matrices between Nymphe sites and the partner's working places will be carried out following the ADR, AND, RIS, and IATA DGR regulations. 

  • Municipal WW - Alcalá, Spain

The site locates at IMDEA Water Institute, founded by the Madrid Regional Government in 2005 within the University of Alcalá campus. 

Contamination: The facilities receive untreated wastewater from the campus contaminated with municipal typical pollutantspharmaceuticals (antibiotics) and microplastics (MPs) - polyethylene terephthalate, bis(2-hydroxyethyl) and mono(2- hydroxyethyl) terephthalates, polylactic acid, polyurethane, polycaprolactone, polypropylene, polyamide, and polyethylene). 

The IMDEA facilities also provide all the analytical equipment for analysing and monitoring pollutants in wastewater. METFI will supply Nymphe partners with samples and analyses of wastewater and supervise/facilitate field tests. 

Meet The Team

Nymphe brings together 17 partner organizations from the EU (Italy, Spain, Germany, The Netherlands, Czech Republic, Denmark, Slovakia, Portugal, Poland, Romania, and Belgium) and a third part from Switzerland as an associated partner.

The consortium was established on the basis of an interdisciplinary approach, the consortium consists of 9 Universities and Research institutions, 6 small/medium entreprises, 1 large company, 2 NGOs. The interdisciplinary approach covers the entire value chain of bioremediation for market uptake:

environmental microbiology/biotechnology, analytics, ecotoxicology, bioinformatics, supramolecular engineering, additive manufacturing, environmental engineering, biological safety, and biotech legislation, companies in bioremediation, socio-economy.


The strategical development of bioremediation is made with and for economic actors of the sector:

  • bioremediation (CENV , METFI, and CHQ Technologies),

  • microbiome modeling & manipulation (BLOM),

  • ecotoxicological testing (ABI),

  • regulatory & biosafety (Perseus)

  • as well as a large end-user (ER).


ER, CHQ, IGB, METFI, and CENV have access and authorization to test bioremediation strategies at contaminated sites.
