Bambooder Wins Circulair Challenge Award 2016!

This afternoon Bambooder was chosen as the most promising entrepreneur of the first edition of the Circulair Challenge, winning a grant of €50.000!

During the Circulair Challenge Award 2016 nine participants got the chance to pitch their idea for the jury, investors and the public. Almer van der Stoel of Bambooder gave a great pitch and convinced the jury of their potential.

The jury, consisting of Manon Klein of Stichting DOEN, Owen Zachariasse of Delta Development Group,  and Martijn Schneider and Peter van Heerde of Rabobank, says about Bambooder: "Bambooder has one of the strongest business cases within the Circulair Challenge. Their short-term/long-term business approach shows their experience and commercial skills. The fact that they are already selling their product proves they can manage a successful business chain."

Bambooder grows and processes bamboo fibres into bio-based composites that can compete with traditional unsustainable materials such as steel and plastics. Bamboo is a fast-growing plant with soil remediation qualities if cultivated correctly. The fibres of Bamboo are extremely strong, but difficult to extract from the plant. Bambooder has invented a technique through which the fibres can be very carefully withdrawn from the stalk. This technique can soon be mechanically applied, so that Bambooder will be able to scale-up. 

Next to Bambooder, other participants showed great potential. GrowX for example found a financer for a building in which they want to develop their vertical farming constructions and Delta Development Group has showed interest in Adaptavate, Hubbel, Skytree and Bambooder. We can therefore conclude that the first edition of the Circulair Challenge was a great succes! 



Circulair Challenge Award 2016

Meet the circular entrepreneurs of tomorrow,

join the Circulair Challenge Award 2016 on May 13th!


The linear ‘take-make-dispose’ economy exhausts the world’s finite resources and pollutes its air, soil and water. In the circular alternative, resources continually re-enter production cycles, bypassing disposal into the biosphere and further depletion. CIRCULAIR CHALLENGE gives nine participating sustainable enterprises the opportunity to scale up their product, thereby facilitating the essential transition from a linear towards a circular economy.

On the 13th of May, the nine participants of the Circulair Challenge will pitch their product for investors. A jury will thereafter award a €50.000,- grant to the most scalable participating company.

Meet our participants, connect with our dynamic network of experts, investors and sustainability frontrunners, and get involved with the newest trends in circular economy thinking!


Location: Circular Expo in Hoofddorp—Rijnlanderweg 916, 2132MN

Time:    May 13th, 14:00-18:00 — This includes a closing with drinks

The Circulair Challenge is an initiative by Enginn, organised in cooperation with Delta Development Group and Stichting DOEN.

Co-innovation: the importance of creating an eco-system

A Blogpost written by Geanne van Arkel

As a startup it is important to create a net-work around you that helps you with challenges you are facing and addressing opportunities that you see. In nature we would call this an eco-system. Working in an eco-system makes you more resilient, since you are not out there on your own. The most important lesson you can learn is that your eco-system should be divers. So how cool the investor is and how big the potential of a client can be, it is not smart to be dependent on only one, since circumstances can change. To quote Charles Darwin: “It is not the strongest of the species that survives, or the most intelligent, but the one most responsive to change."

The science of biomimicry - learning from nature -, has been successfully applied in products and processes. It is really inspirational to see what lessons can be learned when looking at the site But when it comes to circular economy there is more to learn about system-thinking and ways to organize our companies and industries. The word industrial ecologies is used to describe the way companies can cooperate in an eco-system often based on out-put and waste streams. You can learn from nature in not only selling your product, but also create feedback loops in order to be able to deliver product-service systems including take-back systems. Don’t try to do everything on your own. For delivering those services it is smart to partner up since you will have a larger reach. With these services you will be able to build a relationship with your clients, because you are better answering to their needs and you stay close.

The whole idea of working in an ecosystem is that there is diversity in the system and in your network, so you can work on achieving goals together. For a startup this may be even more important. And by creating this network, you create ambassadors that can help you in promoting your company. Therefore I feel the most important dimension of this Circulair Challenge is that you actually meet individuals and organizations that can be part of this eco-system and are potential customers or investors. And sure there are lessons to be shared, both best practices and ‘successful failures’.

Upscaling a Circular Product in a Lineair World

A blogpost written by Hubbel

A blogpost written by Hubbel


The world is (still) linearly organized, and uses fuel and materials as if there is no limit. 

With our circular product Hubbel we offer an alternative to start the transition in the building industry and use of workspace. We need all the help we can get to proof it is possible to disruptively change the system. Therefore we are proud that Enginn, Stichting DOEN, the Delta Development Group and the other founding fathers have selected us and are helping to achieve our goals. 

By participating in the Challenge we could convince our main supplier to get a C2C certificate for our ground-, wall- and ceiling panels that cover 90% of the Hubbel parts. And now other suppliers we invited are also willing to do so. Hubbel parts are re-usable for over more than 50 years. Because of the grant, we were able to test not only mounting the smart parts but also re-mounting them. 

The Economical Board of Amsterdam believes in the Hubbel system as a change-maker, and they invited us at the circular hotspot in Hoofddorp to show our proposition where we will also show our Hubbel to the international trading mission by demonstrating our re-mounted building system outside the exposition centre (next to the building system of C2C founder William McDonough).

Our business model is renewed for the circular economy, where not only the invention, but also the market proposition is developed, and shows how it is possible to make money in a sustainable world. We have also put effort into better communication through an app, a new site and on social media.

Without the help of the Circulair Challenge and their great Enginn team none of this would have been possible. Anna, Thijs, Dirk, Renske, and all the others, thanks! We are looking forward to the completion of this challenge and we hope to accomplish upscaling our product and making it work with values that are grounded in the circular economy.


Hubbel is a company that has developed an innovative building system based on the principles of circular economy. It is made from smart parts and designed to quickly adjust in form, functionality and appearance. The Hubbel has no impact on the environment, all parts are re-useable for more than 50 years to prevent waste.

Hubbel workspace  

We are living in an era where the mobile office knows no bounds. No personal space, no privacyand no peace of mind. Hubbel is bringing personal space (and walls) back to the mobile office. Technology has changed the way we work and now it is time for the working environment to catch up. Hubbel offers pay per use space to work and meet in your own setting on key infrastructural locations.

How to kick-off your business?

A blogpost written by Geert Hoedjes of JAN@

Enginn’s goal is to support and assist starting innovative entrepreneurs in establishing, and further expanding, their sustainable start-up. We - JAN@ Accountants & Adviseurs - recognise ourselves in the ‘starting’ entrepreneur with ambition and passion; that is why we gladly contribute to facilitating and advancing these entrepreneurs. We know a lot is coming at them which they do not think of themselves. We gladly help them with this, and we go even further. We also help entrepreneurs to achieve their objectives. Getting the best out of your business and yourself, that is what entrepreneurs want; getting busy with the things for which you have become an entrepreneur in the first place.

When beginning a business, there are many things that need to be taken care of. We, as mentor of the Circulair Challenge, offer an assistance package so as to expedite the participant’s start.

This package consists of: 1. orientation phase, 2. preparing entrepreneurship phase, and 3. the start of your business.

1. Orientation phase: preparation and brainstorm session
During the orientation phase the participant's business is scrutinised; during the brainstorm session we look at target groups, what the participant can offer these target groups, customer relationships, which channels are most effective at reaching potential customers, and the earnings model. We map the business model with the help of the Business Model Canvas, a powerful tool to make the business as clear as possible.

Experience teaches us that one or two sessions are sufficient to map the enterprise’s business model. We then have a clear view on the enterprise and the business model. Because this process bring together all information on one sheet, the connections between different components become immediately clear as well. The Canvas gives overview and insight. Moreover, it enables us to discuss the information with stakeholders without much explanation.

2. Preparing entrepreneurship phase: setting up a financial plan consisting of an investment budget, result prognoses, liquidity budget and balance projections

After mapping the business model, we expand it into a financial plan. Besides looking at the operating budget, it is crucial to get a clear view on the balance sheet, and as such the liquidity position, of the business. After all, cash is king and profit is an illusion! Especially in the case of young, fast-growing businesses, much money gets ‘trapped’ in working capital. Working capital is the amount of money that is available to make short-term payments. Working capital is needed to grease the wheels of any business’ functioning. The lower the net working capital, the less freedom one has to invest.

The net working capital consists, amongst other things, of:                   €
            Stocks                                                                                                  +/+
            Work in progress                                                                                +/+
            Debtors                                                                                                +/+
            Costs paid up front / other receivables                                          +/+
            Bank balances                                                                                     +/+
            Cash                                                                                                      +/+
            Creditors                                                                                              -/-
            Current account credit                                                                       -/-
            Net working capital

3. The start of your business: creating a holding or operating company, ensuring correct treasury application, starting administration, payroll report VPB and IB, financial statements and deposits.

Second Masterclass

Each of the participants of the Circulair Challenge has the ambition to change the current economic system by developing their product. Some participants want to bring about social change through awareness. Others want to exonerate the environment by introducing an ecological alternative for a toxic building material, or by altering the economic system by leasing a product. All of these ideals fit within a circular economy. The main question is this: how will these products accelerate the transition towards a circular economy? To make a significant difference, the participants need to upscale their production. They can achieve this only by having a viable business model. The goal of the second masterclass is therefore to brainstorm on how this business model should look like and how this business model can be integrated into the business plans of the participants.

The participants are extremely knowledgeable in their own fields of expertise and our masterclass gives them the opportunity to share this knowledge together. They have shared the challenges they encounter during their road towards a circular economy. They have advanced further into their personal inspirations and delved deeper into why they are doing what they do, together with facilitator Iris van den Berg (Freedomlab). This will help them when looking for possibilities for themselves and each other in the near future. 

The Circulair Challenge fosters relationships by connecting the participants not only to each other, but also to important people in the circular economy world. One such individual is Peter Joustra of SADC (Senior Project Manager Schiphol Area Development Company), who provided insight on the state of the art on business models in a circular economy. After the presentation, the participants discussed challenges and opportunities for circular business models during an in-depth session with experts. Among these experts were Douwe Jan Joustra, introducer of the Circular Economy concept in the Netherlands, Martin Zanders (E-mobility) and Rob Oomen (Netherlands Circular Hotspot). Backed by this panel of experts, our participants have access to advantageous circular know-how.

During the second day, Andy Hall, one of the most experienced circular economy consultants in the Netherlands, gave a presentation about sustainable value cycle solutions. He helped the participants set out their business plans, and the communication of their business plans. In the afternoon, participants had the chance to work on their business plans together with experts Martijn Schneider (Rabobank), Shyaam Ramkumar (Circular Developer at Circle Economy) and Mart van Genugten and Taco Leemans (Pot Jonker Advocaten). 

During the second masterclass, the participants learned a lot about circular business models and the role of having a good relationship with your partners. This will benefit them in their road towards success in a circular economy. The participants are now able to further refine their business models and better prepare themselves to present their ideas to all of you on the 13th of May during the third masterclass. The official invitation for this event will follow soon in a newsletter.
