Up to €20 Million for Circular Bioeconomy Consortia: How to Win a CBE JU 2025 Grant

If you work in Europe’s bioeconomy and you’re not looking at Circular Bio-based Europe Joint Undertaking (CBE JU) calls, you’re leaving serious money on the table.

We’re talking project budgets up to €20 million, funded under Horizon Europe, for large-scale biorefineries, urban bio-waste valorisation, bio-based packaging, alternative proteins, sustainable textiles, macroalgae systems, forest biomass valorisation, and much more. This is where research ideas grow legs, walk into factories, and (ideally) outcompete fossil-based incumbents.

Yes, the 2025 call (HORIZON-JU-CBE-2025) has a single deadline and a serious budget: €172 million across multiple topics and funding types. It’s competitive, bureaucratic, and unapologetically demanding. It’s also one of the few places where “We need €14–20 million to scale this” is a reasonable ask.

If you’re part of a serious consortium—industry, research, SMEs, maybe a city or two—and you’re aiming to turn bio-based innovation into something that can survive a board meeting, CBE JU is your arena.

Let’s unpack it so you can decide whether to go all in, and if you do, how not to crash halfway through the portal submission.

CBE JU 2025 Grants at a Glance

What This Opportunity Actually Offers (Beyond the Headline Millions)

The headline is impressive—up to €20 million per flagship project—but the real value is how CBE JU structures these projects.

First, CBE JU doesn’t fund random “bio is nice” projects. Their mission is to build a competitive, sustainable bio-based economy across Europe. That means integrated value chains, serious industry participation, and a credible shot at market uptake.

Three main types of funded action

CBE JU follows Horizon Europe’s structure:

• Research and Innovation Actions (RIAs) – These are the “new knowledge, new tech” projects. Think development and early validation of processes, materials or products. TRL 3–5 territory: lab, pilots, simulated environments. Funding here is ideal for consortia that still need to iron out fundamental science or engineering before thinking about market deployment. Budgets sit around €7 million for topics like:

  • Valorisation of untapped forest biomass
  • Biodegradable delivery systems that reduce microplastics from fertilising products
  • Alternative biomanufacturing routes for natural and synthetic rubber

• Innovation Actions (IAs) – This is where you scale. The expectation is that there’s already promising proof of concept, and now you’re pushing towards demo, validation in real settings, and preparing for market replication. Budgets are around €14 million per project for topics like:

  • Sustainable macroalgae systems
  • Safe and Sustainable by Design (SSbD) products for textiles
  • Scaling up nutritional proteins from alternative sources
  • Continuous biotech processes
  • SSbD bio-based polymers/copolymers for new market applications

• Innovation Actions – Flagship (IA-Flagship) – This is the heavyweight category. Here we’re talking first-of-a-kind biorefineries and industrial deployments at genuine commercial scale. Budgets go up to €20 million per project with topics like:

  • Urban-industrial symbiosis for bio-waste valorisation
  • Bio-based drop-in / smart drop-in platform chemicals
  • Circular-by-design fibre-based packaging
  • Retrofitting existing (bio)refineries for higher-value products

• Coordination and Support Actions (CSAs) – Smaller money, big influence. Around €1 million to structure communities, design curricula, develop skills, share knowledge, and support uptake of research results. The 2025 call includes, for example:

  • New curricula and knowledge-exchange practices for bio-based systems

Why this call is worth the pain of Horizon paperwork

• Scale – You can build real infrastructure, not just a nice PDF and a pilot line in someone’s basement.
• Credibility with industry and investors – “This project is funded under Horizon Europe via CBE JU” opens doors.
• System thinking baked in – CBE JU expects you to think across feedstock, processing, products and sustainability, not just one small step in isolation.
• Longer time horizons – Multi-year projects mean you can actually implement, test and refine instead of sprinting for 12 months and then losing the team when the grant ends.

If your ambition is to publish a few papers, plenty of smaller grants exist. If you want to change how an entire value chain works—from waste streams or biomass feedstock to end products and markets—this is the territory you want.

Who Should Apply (And Who Probably Shouldn’t)

CBE JU isn’t designed for lone wolves. It’s for consortia that look and behave like serious alliances.

The basic eligibility conditions

To be in the game, you need:

• A consortium that meets Horizon Europe / CBE JU rules (multi-partner, cross-country set-up).
• At least one legal entity established in an EU Member State.
• A project that clearly addresses one of CBE JU’s 2025 call topics and fits its bio-based innovation priorities: feedstock, processing, products, communication, and environmental sustainability.
• Compliance with Horizon Europe rules on funding, ethics, and participation.

What a competitive consortium usually looks like

In practice, successful CBE JU consortia often include:

• Industrial partners: Large companies, technology owners, process operators, or manufacturers. They bring market access, facilities, and a path to commercialisation.
• Research organisations / universities: Handling fundamental research, modelling, validation, sustainability assessments, and tricky technical questions.
• SMEs and start-ups: Agile innovators with proprietary technologies or digital tools.
• Public authorities or cities (especially for topics like urban-industrial symbiosis or local biomass use).
• NGOs or clusters for outreach, stakeholder engagement, and wider adoption.

If your project idea only requires two small partners from one country and a small lab bench, this call is likely too big and bureaucratic for you. You might be better off starting with a national grant and circling back to CBE JU once you’ve proven your case and attracted industry.

Concrete “this is you” scenarios

You’re probably a good fit if:

• You’re a chemical company with a pilot biorefinery and want to retrofit or scale it to produce higher-value bio-based chemicals or materials.
• You’re a university research group with strong lab results on forest biomass or macroalgae and already have industrial partners asking, “When can we test this at scale?”
• You’re a city or region with large volumes of food or organic waste and a network of industrial plants that could valorise it into chemicals, materials or energy.
• You’re a consortium already active in Horizon 2020/Horizon Europe but now have a technology mature enough to attempt an IA or IA-Flagship.

If, on the other hand, you:

• Don’t have any industry interest yet,
• Can’t identify a clear product or market,
• Or can’t imagine coordinating 10–20 partners across several countries,

then you might want to join someone else’s consortium rather than trying to lead your own.

Insider Tips for a Winning CBE JU Application

This is not the sort of call you write in August for a September deadline. A strong CBE JU proposal is a project in itself.

Here’s what separates the fundable from the forgettable.

1. Design the value chain first, the work packages second

Reviewers want to see coherent value chains, not a random bag of work packages. Start with:

• Where the feedstock comes from
• How it’s transformed
• What products you’re targeting
• Who buys them and why they care
• How circularity and sustainability are measured and improved

Only after that should you carve it into work packages (WP1 feedstock, WP2 process, WP3 products, WP4 sustainability, WP5 exploitation, etc.).

2. Read the topic text like a contract

Each topic in the Annual Work Programme has mandatory and “expected” elements. Treat them like clauses in a contract. If the text says you must:

• Demonstrate at a certain technology readiness level (TRL),
• Include specific types of partners,
• Address social, economic, and environmental impacts,

then you need to clearly show where that happens in the proposal. Use tables mapping “Expected outcome” to “Where in the proposal we deliver this”. Reviewers love that kind of clarity.

3. Don’t under-scope or over-scope your ambition

For IA and especially IA-Flagship projects, CBE JU expects real industrial impact, but not science fiction. A bad proposal either promises the moon (“We’ll decarbonise the entire plastics sector in four years”) or is so modest it doesn’t justify a €14–20 million grant.

A good proposal focuses on a well-defined but transformative slice of the puzzle, such as:

• A first-of-kind plant using urban bio-waste to produce two specific high-value chemicals; or
• A new class of SSbD bio-based polymers validated in one or two concrete applications (e.g., food packaging, automotive parts).

4. Put sustainability center-stage, with numbers

This is not optional. CBE JU is obsessed (rightly) with environmental performance.

You should:

• Plan Life Cycle Assessment (LCA) from day one, not as an afterthought in month 47.
• Address microplastics, emissions, biodiversity, land use, water use, and circularity wherever relevant.
• Consider Safe and Sustainable by Design (SSbD) principles explicitly for chemicals, materials, and processes.

Get a partner who actually knows how to do LCA and SSbD assessments properly. Reviewers spot fluff instantly.

5. Make exploitation and business planning painfully concrete

For IAs and IA-Flagships, you’ll be expected to provide a business plan annex. That’s not just a formality.

You should be able to answer, convincingly:

• Who will own the foreground IP?
• What’s the expected cost structure at scale?
• What’s the realistic market share you’re aiming at within 5–10 years?
• Which customers are already interested or involved?

Generic “this will be exploited by partners” sentences are basically a funding repellent.

6. Write for mixed audiences

Your proposal will be evaluated by experts, but not all of them will be deep specialists in your prototype enzyme or obscure composite structure. Make sure:

• The abstract and excellence sections are readable by a smart person outside your exact subfield.
• The real technical depth appears in the work plan and methodology, where specialists can appreciate it.

If a non-specialist partner in your own consortium can’t understand the objective and impact sections, you’re in trouble.

7. Get brutal, external feedback

Before submission, ask at least two people who haven’t been involved in drafting to review:

• One person deeply familiar with EU projects / Horizon Europe
• One person who understands the science but isn’t emotionally attached to your structure

Tell them: “I want you to find reasons not to fund this.” Then fix every legitimate concern they raise.

Application Timeline: Working Backwards from 18 September 2025

You have a single hard deadline: 18 September 2025, 17:00 CET. Miss that, and the portal doesn’t care how brilliant your idea is.

Here’s a realistic schedule.

April–May 2025: Topic analysis and partner hunting

• Read the Annual Work Programme 2025 topic texts thoroughly.
• Decide which specific topic fits you best; don’t try to twist your idea into something it clearly isn’t.
• Confirm interest with key industrial players first. If they’re lukewarm, reconsider leading.
• Start building or joining consortia via networks, clusters, and CBE JU info events.

June 2025: Build the concept and roles

• Agree on who coordinates (and make sure they actually have Horizon experience or support).
• Draft a 2–3 page concept note: objectives, value chain, partners, TRL path, impact.
• Clarify each partner’s role and responsibilities, and check internal commitment.

July 2025: First full proposal draft

• Develop the full Excellence and Impact sections.
• Outline all work packages, milestones, and deliverables.
• Start building the budget with your partners. This always takes longer than you think.

Early August 2025: Refinement and internal approvals

• Circulate the full draft internally for comments.
• Refine the work plan, risk assessment, ethics, and sustainability sections.
• Finalise main KPIs, expected results and exploitation strategy.

Late August – Early September 2025: Polish and portal work

• Finalise Part B (technical description) and annexes, including business plan for IA-Flagships and IKAA where relevant.
• Upload everything early to the Funding & Tenders portal and run validation checks.
• Make final adjustments based on formatting/page limit issues.

Absolutely latest: 16 September 2025

• Aim to submit at least 48 hours before the deadline. The portal has a sense of humour and loves crashing right when you don’t need it.
• Do a final page-by-page review: consistency, numbers, partner names, TRLs, topic ID.

Required Materials (And How to Prepare Them Well)

You’ll submit through the EU Funding & Tenders Opportunities Portal, following Horizon Europe formats. CBE JU provides specific templates.

Expect to prepare at least:

• Part A (online forms) – Partner data, budget tables, ethics and security questions. This happens directly in the portal.
• Part B (technical narrative) – Separate templates for:
  • RIA
  • IA
  • CSA
    This is where Excellence, Impact, and Implementation live. Stick to the page limits or the system will simply chop off your text.
• IKAA annex (for IA) – If your project involves in-kind contributions on additional activities, you must follow CBE JU’s IKAA guidelines and FAQ. Discuss this with your finance/legal teams early.
• Business plan annex (for IA-Flagship) – A serious document covering market analysis, revenue projections, investment needs, and exploitation strategy.
• Letters or internal confirmations – While not always separately uploaded, you’ll need informal confirmation from partners for access to facilities, sites, or testbeds. Don’t assume these things are “understood”.

Be methodical here. Assign a proposal manager whose job is to chase versions, keep templates aligned, and make sure no partner forgets their tasks.

What Makes a CBE JU Application Stand Out

Reviewers have limited time and a stack of proposals. You want them to finish yours thinking, “This one actually might work.”

They’ll be assessing roughly along these lines (aligned with Horizon Europe):

1. Excellence

• Clear, specific objectives, not vague aspirations.
• Solid command of the state of the art and how your approach moves beyond it.
• Credible methodology—identifying risks openly, not pretending everything will be smooth.

2. Impact

• Quantified, not poetic. “Reduce greenhouse gas emissions by X% compared to benchmark” beats “significant sustainability benefits”.
• Realistic exploitation and business plans, especially for IAs and IA-Flagships.
• Strong plans for dissemination, communication and uptake across sectors and regions.

3. Quality and efficiency of implementation

• A logical work plan with reasonable effort per partner and work package.
• Partners whose previous experience matches their assigned roles.
• Governance that looks like it can actually manage 10–20 partners without chaos.

What really grabs attention is when a project clearly:

• Fills a critical gap in an existing value chain;
• Has end-users already on board (as partners or strong supporters);
• Demonstrates thought-through sustainability instead of “we’ll do an LCA near the end”.

Common Mistakes to Avoid

These are the things that quietly kill good ideas on evaluation day:

1. Ignoring the exact topic wording
   If the topic demands urban-industrial symbiosis but your project is essentially a rural biorefinery, you’re misaligned. Reviewers will notice in paragraph two.

2. Treating industry as decoration
   Having one token company that contributes 3 person-months and no real risk is not enough for an IA or IA-Flagship. Industrial involvement needs to be deep and central.

3. Overcomplicated consortia with no clear logic
   Twenty partners from fifteen countries can be impressive—or chaotic. If you can’t explain in one paragraph why each type of partner is necessary, you probably have too many.

4. Wishy-washy exploitation sections
   “Partners will explore commercial opportunities” is not a plan. Identify concrete products, services or processes and who will take them forward, how and when.

5. Budget disconnected from tasks
   If one partner has a massive budget but almost no visible responsibilities, that’s a red flag. Likewise, a pilot plant partner with peanuts in their budget looks unrealistic.

6. Last-minute drafting
   The structure of Horizon proposals rewards those who have time to iterate. Rushed proposals usually have contradictions, vague impacts, and badly thought-out risk management.

Frequently Asked Questions

Do we really need a consortium, or can a single organisation apply?

You need a consortium that complies with Horizon Europe rules. At minimum, that means several independent legal entities from different eligible countries. CBE JU is about building European value chains, not funding single-institution projects.

Can non-EU countries participate?

Horizon Europe allows participation from a wide range of associated countries and, in some cases, other international partners. However, at least one legal entity must be established in an EU Member State, and funding rules may differ for non-EU partners. Check the Funding & Tenders portal and Horizon Europe documentation for exact eligibility.

Is this only for large companies and big universities?

No, but they’re often central players. SMEs and start-ups can absolutely participate and sometimes coordinate, especially in RIA or IA projects. The key is that the consortium as a whole covers the full pathway from feedstock to market.

Do we need to have a pilot plant already in place for IA-Flagship?

You need a credible route to first-of-a-kind deployment. That usually means you already have significant pilot data, demonstration experience, or access to facilities that can be scaled or repurposed. If all you have is lab-scale proof of concept, you’re probably better suited to a RIA or smaller IA, not a flagship.

How competitive are CBE JU calls?

Very. Success rates vary, but Horizon-style calls often land in the 10–20% success range. That doesn’t mean you shouldn’t try; it means you should treat the proposal as seriously as building a major new product line.

Are overheads and funding rates the same as standard Horizon Europe?

CBE JU follows Horizon Europe rules and procedures. That means typical funding rates (e.g., up to 100% for certain research organisations; different rates for innovation activities) and standard overhead calculations. Confirm exact numbers in the call documents and with your institution’s grants office.

Where do we find the detailed topic descriptions and templates?

• The Annual Work Programme 2025 contains full topic texts and conditions.
• The EU Funding & Tenders Opportunities Portal hosts the call page, templates (Part B for RIA, IA, CSA), and the online submission system.
• The CBE JU website hosts guidelines and FAQs, including for IKAA and general applicant questions.

Can we ask CBE JU questions before we apply?

Yes. Applicants are encouraged to send questions to info[at]cbe.europa.eu. Answers are often reflected in updated FAQs so all applicants have equal access to clarifications.

How to Apply: Concrete Next Steps

If this sounds like the right scale and ambition for your project, here’s how to move from “this is interesting” to “we’re submitting”.

1. Read the official call page and topic texts carefully
   Start at the official CBE JU open calls page:
   https://www.cbe.europa.eu/open-calls-proposals
   Then follow through to the EU Funding & Tenders Opportunities Portal entry for HORIZON-JU-CBE-2025 and the Annual Work Programme 2025.

2. Confirm internal buy-in and resources
   Talk to your management, tech leads, and legal/finance people. Coordinating or even just participating in a CBE JU project is a multi-year commitment of staff time and resources.

3. Build or join the right consortium
   Use existing networks, CBE JU Info Day materials, industry associations, and brokerage events to find partners. Don’t just invite friends; invite the right capabilities.

4. Assign a proposal leader and a writing team
   Someone needs to own the process, timeline, and version control. Ideally, that person has Horizon experience or support from a project office.

5. Get familiar with the Horizon Online Manual
   The Horizon Online Manual explains the technical application steps, from registration (PIC numbers) to submission and evaluation. Read it before you’re under deadline pressure.

6. Start writing early and iterate
   Draft the Excellence and Impact sections first; they define everything else. Then refine the work plan, budgets, risks and governance.
