Project Summary

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 artificial fertilisers, for which the EU is heavily dependent on imports. Moreover, the production of artificial 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 artificial 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.

French producers of RDF's share their experience

Posted on

In the process of reducing the use of limited natural resources, such as phosphorus of mineral origin, recycling-derived fertilisers (RDF) are an interesting alternative to artificial fertilisers. In the below video, Laurent Varvoux, co-leader of the Nitrogen and Sulphur group at COMIFER, and 3 French producers shed light on what RDF are and the opportunities they can offer in terms of fertilisation and sustainability.

ReNuMaps tool and full report now available online – insights in recycling-derived fertiliser demand

Posted on

ReNu2Farm aims to increase recycling rates of the main plant nutrients, N, P and K, by focusing on the demand of farmers. A study carried out within ReNu2Farm in 2019 under the lead of researchers from NMI (NL) and CIT Cork (IRE) is now published online and in full length. The work was previously presented at several meetings and conferences (e.g. ManuResource 2019 and recently at the International Fertiliser Society Webinar) where it received great interest from stakeholders, in particular policy makers and producers of recycling-derived fertilisers.

ReNu2Farm agronomic trial protocols for evaluation of recycling-derived fertilisers now online

Posted on

Within the ReNu2Farm project several project partners, have carried out trials to derive reliable information on agronomic value, nutriënt content and safety of recycling-derived fertilisers. Protocols taking into consideration the specific nature and properties have been developed for all trials. To facilitate future research and practical consulting of farmers on the fertilising value of these novel products, the ReNu2Farm consortium decided to publish all used protocols so that they can serve as a reference in the future.

Farmers Attitudes to RDF Sources Discussed at the Civil Engineering Research in Ireland Conference (CERI2020)

Posted on

The Civil Engineering Research in Ireland Conference (CERI2020) was held virtually on 27th-28th August 2020. Although originally intended to be held in CIT, due to the Coronavirus restrictions it moved entirely on-line. This national conference focused on promoting civil engineering research and practices in Ireland. The conference was available to academics, researchers and professional practitioners with over 130 papers presented in total. Read More

RAMIRAN “Recycling of Agricultural, Municipal and Industrial Residues in Agriculture Network” is a research and expertise network set up over 25 years ago to improve nutrient utilisation and minimise the environmental impact from livestock manure and other organic material use in agricultural systems. This conference was last held in 2017 and attracts up to 250 delegates from across Europe and further afield. RAMIRAN 2020 will be organised by ADAS, Rothamsted Research and Bangor University and held at the University of Cambridge in Eastern England, UK.

Biobased solutions for climate change The 16th edition of the International Conference on Renewable Resources & Biorefineries will take place in Ghent, Belgium from Wednesday 3 June until Friday 5 June, 2020. Based on the previous RRB conferences, this conference is expected to welcome about 350 international participants from over 30 countries. Delegates from university, industry, governmental and non-governmental organizations and venture capital providers will present their views on industrial biotechnology, sustainable (green) chemistry and agricultural policy related to the use of renewable raw materials for non-food applications and energy supply. The conference further aims at providing an overview of the scientific, technical, economic, environmental and social issues of renewable resources and biorefineries in order to give an impetus to the biobased economy and to present new developments in this area. The conference will provide a forum for leading political, corporate, academic and financial people to discuss recent developments and set up collaborations. The three day international conference will consist of plenary lectures, oral presentations, poster sessions and an exhibition. Companies and research organizations are offered the opportunity to organize a satellite symposium.

ReNu2Farm Seminar in the Learning Network of BSc and BSc (Hons) Sustainable Farm Management and Agribusiness in the Wexford Campus of the Institute of Technology Carlow

, The Wexford Campus of the Institute of Technology Carlow

In the ReNu2Farm project partners are very much interested in developing, testing and evaluating recycling-derived fertilisers (RDF) and demonstrating their suitability to replace their conventional traded equivalents. In addition to those, they are also interested in communication of project work to relevant audiences. Such target groups also include the so called “learning networks” which are groups of people training in relevant areas. One such expedition for outreach was undertaken on Tuesday 28 January 2020 by the ReNu2Farm Institute of Technology Carlow project manager, Dr Thomaé Kakouli-Duarte.
