The three-year research project FER-PLAY, recently concluded in Brussels, marks a significant milestone in the development of circular fertilizers in Europe. At the same time, the European Commission introduced a new vision for agri-food policy, which will serve as the foundation for aligning environmental goals with the economic realities of agriculture over the next five years. In this context, circular fertilizers are not just an alternative — they represent the future of European agriculture.
Traditional vs. Circular Fertilizers: What’s the Difference?
Conventional mineral fertilizers are produced from finite, often imported resources using energy-intensive technologies. While they offer rapid nutrient release, they also lead to soil depletion, water pollution, and high greenhouse gas emissions.
In contrast, circular fertilizers are derived from recycled organic residues, bio-waste, or by-products such as digestate from biogas plants. Their use:
-
reduces dependency on imports;
-
lowers the risk of soil and water contamination;
-
improves soil structure and fertility;
-
cuts input costs for farmers.
FER-PLAY: 3 Years of Research Supporting the Circular Transition
Supported by the European Commission under the Horizon Europe program, the FER-PLAY project brought together 12 partners from 6 countries. Its objectives were to:
-
Identify types of circular fertilizers made from secondary raw materials;
-
Assess their effectiveness, environmental impact, and economic feasibility;
-
Provide recommendations for large-scale market implementation;
-
Facilitate dialogue with farmers, producers, and policymakers to align the vision.
The results are impressive. By 2050, circular fertilizers could replace up to 3.77 million tonnes of traditional fertilizers, leading to:
-
88% reduction in CO₂ emissions;
-
87% reduction in N₂O emissions;
-
20% reduction in fertilizer imports, equivalent to savings of up to €689 million per year.
Flexsol’s Role in Circular Agriculture
As a manufacturer of flexible tanks and covers for biogas installations, Flexsol supports farmers and biogas producers in the efficient storage and transportation of digestate — a key input for circular fertilizers. This enables:
-
Environmentally safe storage of processed organic material;
-
Nutrient-preserving application of fertilizers;
-
Advancement of sustainable closed-loop agricultural practices.
Looking Ahead
According to José Martín Soriano Disla, project coordinator at CETENMA:
“The FER-PLAY project paves the way for the most efficient use of circular fertilizers. Farmers and agricultural businesses need access to reliable information and a stable regulatory framework to make informed choices toward sustainable farming.”
This vision calls for not only support for innovative solutions but also the creation of a unified European platform to share knowledge, best practices, and research findings. The focus is on building trust in circular fertilizers and gradually transitioning from mineral-based inputs to safer, more sustainable alternatives. These efforts are essential for shaping the agriculture of the future — sustainable, resource-efficient, and environmentally responsible.
