The Interreg NWE ReNu2Farm project aims at increasing the recycling rates of plant nutrients nitrogen (N), phosphorus (P) and potassium (K). P and K are limited and finite resources, and production of N fertilisers is energy intensive. Despite a number of recovery technologies been at a mature stage, the use of recycling-derived fertiliser (RDF) products by farmers has been limited to date. The aim of ReNu2Farm is to put the farming community at the heart of the research, therefore stakeholder engagement is essential to the success of this project. As part of this stakeholder engagement, the ReNu2Farm team was involved with the anaerobic digestion and digestate demonstration, which took place on March 12th in Cork, Ireland. Read More
The ReNu2Farm project is designed to increase the recycling rates for the plant nutrients nitrogen (N), phosphorus (P) and potassium (K) in the primary food production chain in Northwest Europe (NWE). Up to now, farmers have essentially been using mineral fertilisers, for which the EU is heavily dependent on imports. Moreover, the production of mineral fertiliser requires large amounts of energy. Paradoxically, however, there are several regions with a nutrient surplus in NWE. There are also technologies for recovering those nutrients, but until now they have remained little-used by farmers.
The project strives for an exchange of nutrients between the following countries: IE-UK, DE-NL and BE-FR. In each of these areas there are regions with nutrient shortages and surpluses. Nutrient-surplus regions in NWE include the Netherlands, Flanders (Belgium), Bretagne (France) and Ireland. The regions that have great potential to replace mineral fertilisers, due to their high use thereof, are located in Northern France, Wallonia (Belgium), the East of England and Ireland.
First of all, the researchers are investigating the precise current situation on nutrients and technologies in the field of nutrient recovery in NWE. They will then deploy these technologies in practice, for both the production and upcycling of products from recycled nutrients. The largest waste streams for producing these products are sewage sludge, food wastes and manure.
The scientists are considering possible market barriers. They will then adapt the products so that they more closely match the needs of users.
On the basis of desk studies and info sessions with farmers comes an assessment of the regional demand for nutrients and performances of the products. In order to determine the potential for replacement by recycled nutrients, the researchers are collecting information on current fertiliser use and the types of agriculture and crop rotations for each region. From the perspective of the legislation it is also important to know the impacts of the products on the soil and the environment.
Where there are markets for recycled nutrients, what their pricing looks like and what the attitude of farmers and the policy is with respect to them are still open questions right now. The researchers are assessing the economic market value of the products on the basis of production costs and interest amongst the stakeholders. They are identifying legal pressure points regarding conditions and requirements on fertilisation management and transport.
The collected knowledge and techniques are being fed back to the stakeholders via articles, workshops and demonstrations. This will help overcome the knowledge gap amongst farmers. By spreading information and success stories, but also by further expanding to other sectors and regions, farmers will become better able to apply larger amounts of recycled nutrients over the long term.
The long-term goal is for farmers in the involved regions to replace 2% (-108,000 tonnes N, -8,000 tonnes P, -120,000 tonnes K) of the artificial fertiliser with recycled nutrients within five years, and 6% (-324,000 tonnes N, -24,000 tonnes P, -360,000 tonnes K) after ten years.

After Soil-Concept produced the ash from pure sewage sludge last year, it will now be tested in a field trial. Already last year, tests were carried out in small trials. Read More
In March 2020 two field experiments are laid out for the third and last year within the Netherlands (see pictures). The objective of the field experiments is to explore the effects of differences in organic matter input with animal manure, household waste compost (a recycling-derived fertilizer) and/or verge grass on soil quality (e.g. organic matter content and quality, water holding capacity, etc.), crop yield and N uptake of maize and on the risk of nitrate leaching (determined with nitrate in soil profile after harvest). The field experiments are located on sandy soils in the Province of Gelderland, near Wageningen. One field experiment was located on a sandy soil with a deep groundwater table (> 5 m; no irrigation) and the other one on a sandy soil with shallow groundwater table (> 1 m; with irrigation).

In this last year of the Interreg NWE ReNu2Farm project, the bi-annual meeting between the European partners organised by Arvalis was held in France, at the Boigneville station in the Ile-de-France region. The Boigneville station on which approximately 150 employees are working, is the largest of the 27 Arvalis stations covering the French territory. Read More
After the unsuccessful pot trials with Spinacea olaracea (spinach) as part of WP T2, D2.2, the experiment was repeated with Lactuca sativa (lettuce) under controlled conditions to determine fertiliser performance at a level of plant availability and to determine the nutrient use efficiency of the recycling-derived fertilisers and their blends.

Analysis of legal regulations on direct effects for the nutrient management in Germany – impact assessment of EEGPosted on
The biogas plants currently in operation in Germany significantly contribute to the provision of renewable electricity and renewable heat. Since the amendment of the EEG (Renewable Energy Law) in 2014, the number of new biogas plants has declined sharply. Read More

Recycling-derived fertilisers (RDFs) are recycled products from different sources that can be used to replace mineral fertilisers. These RDF products have a high nutrient value, are readily available, and are safe to use. Farmers in seven countries across NW Europe were surveyed to determine their experience of using 15 different RDF products. A high number of participants took part in the survey, 1225 in total, including 250 participants in Belgium, 679 in France, 65 in Germany, 149 in Ireland, two in Luxembourg, 73 in the Netherlands and seven in the United Kingdom.

In order to obtain the highest possible exchange between different Interreg projects, Soil-Concept contacted different project partners from the agricultural sector in Luxembourg, who are or have been active in Interreg or Horizon projects. It should be an exchange between the projects and the possibility to have common goals and projects for development. Read More
