Circular systemic solutions: the food-water-nutrient chain

Applying circular economy to a single process is useful. Applying it across an entire value chain is another level entirely. They are called Circular Systemic Solutions (CSS) and sit at the heart of the European strategy for the circular transition. 🔗

The concept works like this: rather than intervening at a single link in the chain, the entire system is analysed — from primary production to processing, distribution to waste management — engaging all stakeholders and identifying synergies across sectors. 🗺️

A concrete example comes from the region of Castilla y León in Spain, a pilot region for the EU Circular Cities and Regions Initiative. The CSS developed for the food-water-nutrient chain starts from one figure: mineral fertilisers account for over 30% of farm costs in the region (€414 million in 2020). Phosphorus, an essential component, is classified as a critical raw material with reserves heading towards depletion. 💰

The solution? Recovering residual organic matter generated along the chain — from food waste to sewage sludge — and converting it into biofertilisers, reducing dependence on mineral fertilisers. With cascade uses: biogas and biomethane from digestion, digestate as fertiliser, extraction of substances for cosmetics and nutraceutics. 🌱

The ACE-EX programme includes a dedicated module on designing circular systemic solutions.

Repair, reuse, refurbish, recycle. The so-called “R-strategies” of the circular economy are not slogans — they form a precise hierarchy of interventions to extend the life of products and materials. And in agriculture, they have very practical applications. 🔧

Take preventive maintenance of farm machinery: tractors, combine harvesters, drip irrigation systems. In a linear model, equipment is used until it breaks and then replaced. In a circular model, scheduled inspections, lubrication, filter changes and component checks extend the useful life of equipment, reduce operating costs and generate less waste. ⚙️

Agricultural cooperatives across several European countries already offer shared repair services to their members, making interventions accessible that would otherwise be too costly for an individual farmer. 🤝

In the wine sector, reusing containers and bottles is well-established practice in many cellars. In cereal production, sharing machinery between farms reduces the number of items manufactured and their associated impacts.

The logic is straightforward: the tighter the loop, the fewer resources consumed. Maintaining is better than repairing. Repairing is better than recycling. Recycling is the last resort, not the first. ♻️

One litre of olive oil. How much water did it require? How much energy? How many emissions did it generate from field to shelf? And after consumption, what happens to the bottle, the residues, the by-products? 🫒

These are the questions that Life Cycle Assessment (LCA) addresses: a standardised methodology (ISO 14040/44) that measures the environmental impact of a product, process or service across its entire life cycle. From raw material extraction through to final disposal — or, within a circular framework, re-entry into the production cycle. 🔄

The LCA course developed within ACE-EX covers 30 hours of training and addresses five dimensions: an introduction to the methodology, the phases of analysis, environmental LCA, social LCA and economic LCA.

Each lesson concludes with an assessment questionnaire. The practical element? A full case study on the life cycle assessment of wine production. 🍷

This is not an academic exercise. LCA is the tool through which agricultural businesses can identify where their impacts are concentrated, where to intervene to reduce them and how to communicate their environmental commitment credibly. 📋

Developed by AINIA (Spain), the module is available on the project platform.

Circular economy is often discussed in environmental terms. Less frequently do we look at the economic figures, which tell an equally compelling story. 📊

According to European Commission estimates, the circular economy could generate up to 700,000 new jobs across the EU by 2030. In the agri-food sector, circular models could cut costs linked to waste management and healthcare by up to €550 billion, whilst reducing CO₂ emissions by 48% over the same period. 💶

These are not merely aggregate figures. For a small winery, turning grape residues into organic fertiliser means spending less on chemical inputs. For an olive oil mill, converting pomace into biomass means generating energy and reducing dependence on external suppliers.
For a cereal farm, composting harvest waste improves soil productivity and cuts fertilisation costs. 🚜

The circular economy also creates local employment: from compost management to reverse logistics, from sustainable product design to life cycle analysis. New skills for new markets.

The module on the economic impact of the circular economy, within the ACE-EX training programme, explores each of these areas with data and concrete case studies. 📈
