No beans left behind: The Circular Economy in VALPRO Path

What if the solution to our growing food crisis is hiding in a circular economy?

Each year, Europe’s food industry generates millions of tonnes of by-products, peels, pulp, spent grains, whey and oilseed cakes, that often go to waste. At the same time, the demand for sustainable, nutritious food is rising faster than the current systems can handle.

This contradiction is at the heart of a global challenge: How do we feed a growing population without exhausting the planet?

The answer may lie in circular thinking, one of the core principles of the VALPRO Path project.

By changing agricultural and food side streams into high-value and protein-rich ingredients, VALPRO Path is changing how we think about food waste. It’s not just about reducing what we throw away; it’s about building a regenerative food system.

Circularity in Practice: VALPRO Path’s Business Models

Modern food systems create a large amount of food waste, from peels, pulp and whey, to spent grains and oilseed press cakes. The materials are often thrown away or not efficiently used, despite being rich in proteins and bioactive mixtures.

VALPRO Path is working to change that. Through the project partnership with researchers, industry partners and policymakers across Europe, the project is developing innovative ways to valorise protein-rich side streams. These excesses are reused into high-quality food ingredients, reducing waste, supporting sustainability goals and strengthening local food systems..

Rather than a single solution, VALPRO Path is working on circular business models across Europe, created for different resources, technologies and market needs. These models aim to show how circular principles can be applied at every stage of food production:

1. Plant-Based Burgers: Locally grown lentils and chickpeas are transformed on-site into fresh plant-based burgers, reducing food miles, creating new income for farmers, and meeting the demand for sustainable meals.

2. Climate-Smart Variety Tool: This model uses smart tools to help farmers match crop varieties to regional conditions. The result: better crop performance, higher yields and more resilient food systems,  grounded in local data and sustainability science.

3. Intercropping for Protein Yield Optimisation: By growing peas and faba beans together, farmers can improve yield stability, soil health and reduce risks like lodging. This hybrid cultivation approach supports food and feed producers with more consistent, efficient harvests.

4. Smart Labels: Food products are equipped with smart labels that track carbon footprints and nutritional value, giving consumers transparent insights into the impact and quality of their plant-based foods, potentially reducing discarded or misused food.

5. Legume Pasta: Lentil and chickpea flours are transformed into artisan pasta with bold flavors, high protein content, and regional sourcing. By using locally sourced surplus legumes, the process prevents food waste and turns them into value-added products. The result is a consumer-ready proof of concept for circular, healthy, and locally rooted eating.

The Circular Economy Model: Closing the Loop

The traditional food production model, take-make-dispose, is no longer viable. A circular food economy is built on the ideas of reuse, recycle and repurpose, where waste is not discarded but fed back into production.

According to BCC Research, circular innovation is gaining global traction in the food sector, with companies recognising the economic value of what was once waste. VALPRO Path is part of this change, but embedded in local groups and science-driven collaboration.

A Look Beyond: Global Inspiration for Circular Protein Innovation

While VALPRO Path focuses on European food systems, its mission aligns with broader global efforts to rethink protein production.

Happy Plant Proteins – Developed by VTT in Finland, uses local crops and industrial side streams to create affordable and healthy plant-based foods. It proves that circularity, nutrition and local strength can go hand in hand.

Cross-Sector Synergies – The Good Food Institute – The Good Food Institute highlights how side streams from brewing, starch and agriculture can serve as raw materials for plant-based protein production, turning one industry’s waste into another’s source of innovation.

Whey Protein as a Circular Success – Green Queen – Whey was once a dairy by-product with limited use, but now the protein is a popular ingredient in the health and fitness industry. Its story is an example of how waste can be reevaluated through innovation.

Feeding the World Without Destroying the Planet

As National Geographic emphasises, feeding a growing global population requires strong shifts in how food is produced, distributed and consumed. Replacing meat and dairy with plant-based proteins is only one part; we must also ensure that these alternatives are produced sustainably.

VALPRO Path addresses this by making sure new food solutions are:

• Locally sourced (reducing food miles and import dependency)

• Waste-conscious (valorising what would otherwise be thrown away)

• Economically possible (through scalable, community-based business models)

This is not just innovation, it’s system redesign.

Looking Ahead

Circularity isn’t just a technical solution; it needs collaboration across sectors. Farmers, food manufacturers, researchers and policymakers must work together to normalise food recovery and reuse at all levels.

VALPRO Path demonstrates this in practice. Its cross-sectoral partnerships and pilot projects show what’s possible when waste is treated as a resource and business models are redesigned for circularity.

Conclusion

From Italy to Ireland, VALPRO Path’s business models show how circular food systems are already taking root in Europe. By transforming protein-rich side streams into food, feed or functional ingredients, the project contributes to climate resilience, economic innovation and food security.

This change from waste to food is not a dream. Through collaborative innovation and smart use of local resources, VALPRO Path is turning circular thinking into action, proving that sustainability, health and economic opportunity can go hand in hand.
