We need more circular factories!

As entrepreneurs in the circular economy, it is our observation that too few circular startups make it to scaleups.’ Sabine Biesheuvel (co-founder BlueCity) and Lindy Hensen (co-founder PeelPioneers & Tekkoo)


The Netherlands aim to have a circular economy by 2050: a waste-free economy that runs – as much as possible – on sustainable and renewable raw materials, in which products and raw materials are reused. This requires scaling the circular ideas we already have and building a new processing industry.


We know from experience that scaling a circular startup is complicated, especially in the phase from prototype at lab-scale towards real production in a demo plant. Circular Factory is the supporting start-to-scale-up program dedicated to this phase, offering specific knowledge and a tailor made ecosystem of partners and experienced entrepreneurs.

The program

So, what’s in it for you?! Based on our experience as and with circular entrepreneurs, we developed a program that centers on five topics, each essential to building a circular factory:


get your sourcing, logistics, quality control & legal status

from interest to contract and product certification

Plant design
preparing for a fit-for-purpose plant

building the storyline & finding the right financing mix

the right people for the right job

The program consists of the following phases:


1 Scouting & selection

3 months

In this phase, we open the call for potential Circular Factory participants. We search far and wide for startups that are ready to become a scaleup. Registration for 2023 is allready closed. If you are interested in participating next year you can send an e-mail to info@circularfactory.co.

2 Due Dilligence & matchmaking

3 months

On September 4th 2023 the second edition of Circular Factory has kicked off. On September 21th, 27th and October 5th, 12th and 18th, the selected startups will gather with BlueCity and Tekkoo, and dive into feedstock, customers, plant design, finance and team during the Due Diligence Days. Together with experts we determine your needs in terms of expertise and experience and define a roadmap to build your value proposition and business case for investment. This OKR roadmap is the guideline for the rest of the Circular Factory program. We also match you with experts that can help you with these needs in matchmaking sessions.

3 Hands on support, expert sessions & peer to peer learning


In this phase, you’ll receive support related to your roadmap. There will be six expert sessions related to Feedstock, Customer, Plant design, Financial modeling and Team, quarterly personal meetings with BlueCity and Tekkoo related to your OKR roadmap, four site visits to other circular (demo) plants, continuous matchmaking with experts and partner events for networking. All of these are unique opportunities, bringing you closer to the goal of opening your own circular factory.

Alumni – participants 2022

For the first edition in 2022, Tekkoo and BlueCity selected six startups. Bakkersgrondstof, Biophilica, BlueBlocks, Fairm, MaGieCreations and Nature’s Principles. These six startups ended their participation of the program in 2023, after working towards their ultimate goal: building their own circular factory.


The past year, the startups started working on all the themes with which they remove the greatest risk for financiers: recording contracts from suppliers (feedstock) and customers, a professional plant design with an underlying financial model and finding a location and the right safety measures. The companies are now investor-ready and we desperately need them in the Netherlands to ensure that we use our raw materials in a smarter way. The demo factories to be built cover a wide range of products; from lactic acid to seaweed materials and ingredients based on brewer’s grains and residual bread.



Outlander Materials, Hollands Wol Collectief, Cano-ela, NoPalm Ingredients, Pakt Packaging and Pectcof; the six start-ups in the second edition of Circular Factory

The second edition of Circular Factory has started with six new startups that want to be prepared for building a demo factory. All six startups have real potential to provide circular alternatives on industrial scale and this is desperately needed. The coming nine months the Circular Factory programme guides the six startups through the challenging scaling phase from pilot to demo plant.

Circular Factory supporter Invest-NL about the future of circular startups in the manufacturing industry: “How can we use circular strategies to create a just and liveable society for all?”

Invest-NL is one of the supporters of the Circular Factory program. In this interview, Maud Hartstra and Guy de Sévaux discuss the importance of scaling up circular startups. “All kinds of developments are underway, which means that many more circular start-ups will be founded in the coming years. Circular Factory is designed for circular startups in the manufacturing industry that want to scale their production by building their first factory; and help them to make this factory circular. In addition to these startups, we also see on a larger scale a new focus of moving production closer to home. More and more manufacturing companies previously located in Asia and Eastern Europe are returning to Western Europe. With the Circular Factory program we want to point out to the entire value chain that making things circular and sustainable requires a different approach and mindset, but also changes in business models and new ways of financing. As far as Invest-NL is concerned, Circular Factory is coming at the right time.”
