Greatwaves stops cleantech product to focus on core strength

At the end of the BeStart programme in 2019-2020, Wouter Zijlstra from Greatwaves concluded that his WiFi transmitters with integrated sensors to make buildings more sustainable didn’t fit to the market. How come? And what does this mean for his company? Let’s find out…

Pyrolyze converts waste plastic and waste motor oil on site to new raw materials

As a child he wanted to be an astronaut, but that was not a profession according to his teacher. Business consultant it became to be! Peter Klaren founded the company Pyrolyze together with his partner Raymundo Hooten. Together they want to solve environmental problems in a decentralized way. Not by transporting waste, but converting it on site into useful new products.

Last month they launched a mobile pyrolysis machine, with which they can convert waste motor oil into diesel, naphtha, gas and carbon black. Also they will soon be launching a machine for converting waste plastics into direct usable resources. How will this device change the world? An interview with Peter.

What is pyrolysis?

“Pyrolysis is a technology in which you convert carbonaceous materials into new raw materials at a high temperature, without adding oxygen. At Pyrolyze we do this with two mobile machines: one for waste motor oil and one for waste plastics. The waste engine oil machine can process 350 liters per day and is ready for production. The machine for waste plastics is ready in design and will soon process 150 kilos of waste plastic per hour. Both devices convert their waste stream for 100% into new products: 50% clean diesel for use in vehicles, 30% naphtha as raw material for raw plastics, 10% gas for energy supply of the device and 10% carbon black for the pressing of floor tiles.”

Afvalplastic omzetten

What environmental problem do you solve with this?

“The problem of inefficient and incomplete waste processing. If you look at the Netherlands alone, only about half of all plastic waste that is collected can be recycled. The rest serves as fuel for incinerators and comes with enormous transportation costs. The energy value of incineration is relatively small and the pollution relatively high. With our pyrolysis system we convert the entire waste plastic locally into new products of value without any emissions. In this way we make the residual flows completely circular and we save tons of CO2 because little transport is required.

Our waste engine oil pyrolysis machine is especially interesting for developing countries. There is no one there to collect the waste oil from garages, so the stuff just runs into the ground. That is not only a shame, but it also causes enormous pollution. A little bit of waste motor oil can pollute a whole stream. ”

Completely circular! How is it possible that your machine did not yet exist?

“The technology of pyrolysis is complex and works at extremely high temperatures. If you want to implement this in large reactors on a central scale, the reactor technology is almost impossible to control. As a result, many major initiatives in this area have already been killed. The sweet spot of our machines is that we carry out the process in a small decentralized scale. You can literally walk around the machine and replace parts directly if necessary. This allows us to continuously optimize and guarantee the quality of the output. ”

Isn’t this decentralized approach also a disadvantage in the centrally regulated waste industry?

“Not necessarily. Our product offers major advantages for waste management companies. Because the machine is so easy to move, you can place it wherever you want: even in the middle of your waste separation station. Where you normally pay a gate fee to have the waste plastics removed, you can now get paid for the resources you produce with our machine.

But waste management companies are not our only potential customers. We are in discussion with governments, the food industry, companies in packaging materials, chemical groups, etc. We can easily move the machines on a trailer or ship worldwide. So installing it on a polluted beach in Bali is also possible. On our website we receive daily questions from all over the world. That gives us confidence that the concept is going to work.”

What can BeStart do for your company?

“During the first coaching session, we were mainly challenged whether we had thought of everything. The conclusion was: you have the company well underway. The product, the vision, the strategy and the ROI are correct. We have 5 potential customers for our waste oil machine and an R&D project is coming up. At the same time, with Pyrolyze we enter a process of which we do not know the course and outcome. Of course it is nice to use the knowledge and experience of people who have played the game more often. In addition, we hope to gain many useful contacts via the BeStart network. ”

How can the BeStart network help you?

“We are looking for potential customers who have a waste problem and who see a business case in solving it. We use a three-stage rocket:

  1. Testing the waste materials of our potential clients on a lab scale. Which waste oils and waste plastics do you have?
  2. Run a pilot project with a smaller installation at the customer’s location. Tests run with their waste material on a batch level.
  3. Purchase and instruction of the large installation for continuous processing of waste flows.

For people who are interested: on our website we explain the machine and the pyrolysis process completely and you can even purchase the waste engine oil installation. The installation for waste motor oil will soon be available for viewing by appointment in Amersfoort. There the machine will be set up next to an innovative new-build home from Heilijgers, which largely consists of styrofoam. At the end of the life cycle, the house can be recycled by our installation and so the circle is complete again.

BeStart results since 2016

These numbers really make us proud. Since 2016 our startups have a 83% success rate. At this point there are 39 companies from the BeStart programme that work on a cleaner, more sustainable world 🍃.

So to everybody from our beautiful network, members from the board, people who have coached or taught our startups: THANK YOU. We are proceeding full force with 9 new clean tech heroes in the 2020-2021 accelerator.

This is the 2020-2021 line-up

A healthy breakfast on the go. This is Eatcup!

Product developer Jelte Steur quit his job at Pezy to focus on a product he really believes in: Eatcup. But what is Eatcup anyway and how did this idea come to life? You can read all about it in this interview with Jelte.

What is Eatcup?

‘Eatcup helps people enjoy their own breakfast on the go, for when they don’t have time at home, for example in the morning. It is a cup you can eat from because the food is pushed up to the top where you can take a bite. It is just as easy as sipping coffee, but then with your own homemade muesli or granola. In a video on my new website I show how it works.’

How does Eatcup contribute to a cleaner world?

Eatcup prevents the use of single-use-packaging of for example granola-bars and drink-yoghurts. And because people can prepare their own healthy food, they can also choose for organic and locally grown food.

That will also save money spent at the train station. Where did you get this idea?

‘In my job as a product developer with Philips, I got an itch after a while. How much better is the world going to be with this new shaver? I looked around for relevant problems or product that I felt would make this world a better place.

One Saturday morning my wife said: “I love this muesli and it is healthy, too bad I don’t have time during the week to eat it. I always leave so early, that I end up eating a sandwich in the car.” At that moment I clicked: That is a relevant problem I would love to solve! It was on Christmas eve when I tinkered with an old pump for an air mattress, to test whether I could push muesli upwards with a plunger and easily eat from the top. And it worked! Now, a couple of years later, I have a working prototype that can be used with one hand, is easy to clean and also looks good!’

What is your ambition, and your biggest challenge of the moment?

‘I have a few working prototypes that have been tested over a long time. Technically it is possible. Now I have to investigate if I can build a business. Can it be manufactured in series? Is it economically viable? This year I want to create a pilot series and sell it to answer these questions. Next up is the strategic question with whom I can and want to scale this. The BeStart accelerator fits this development perfectly, both for my company and for myself as an entrepreneur.’

What have you experienced so far in the BeStart accelerator?

‘The intention alone to join, and the starting up of the process already has had an impact. Setting goals and sparring with coaches has sharpened what I do and how I approach it. And the real program has yet to get started! The exposure after the announcement of my selection for the programme was an additional push I needed to get my website in order. Now I finally have a place where I can explain how Eatcup works and where people can sign up for the pilot launch. So if you are thinking: a healthy and calm breakfast on the go is something for me: sign up on

Well done. What are you looking forward to in the coming months?

‘If you are talking about BeStart: actually meeting the coaches and other participants. I have looked at a few websites and it is exciting to note the diversity of the participants especially. The most important aspect is meeting each other in person and hopefully we can do that in May and June and really get started.’

More info about these startups.

The jury, consisting of Henk Split from YnBusiness, Carl Schultz from Paques, Diederik Jongema from FOM and Anne Been from Enablemi, judged the startups based on a few important criteria. For example market chances, contribution to a sustainable world and suitability for the BeStart accelerator. ‘Although the pitches were held using videoconferencing, the quality was very high,’ commented project director Ronald Wielinga at the end of an intense afternoon. ‘We were very impressed by the creativity and the enthousiasm of the companies and we have been able to select some amazing startups. The coming year, we are going to help them to make large steps!’

Why follow through in times of Corona?

The accelerator programme starts in April with online sessions, despite the Corona crisis. ‘Especially in these times, we have to help vulnerable companies like startups’ concluded Ronald Wielinga. ‘Making the right entrepeunerial choices is more important than ever. In our knowledge and coaching programme we will give these aspects extra priority. Of course we will also be available to our alumni.’

March 26th Startup selection day for 2020 – 2021

Thursday March 26th, we will select the cleantech startups that will participate in our 2020 – 2021 accelerator programme! The candidates will pitch for a diverse jury from our BeStart network. Due to the Corona virus, the pitches will take place online, using Microsoft Teams.

On Friday march 27th we will publish the final lineup on our website, Twitter and LinkedIn!

DemoDay 16 March cancelled due to Corona virus

Due to the Corona virus, we have decided to postpone next week’s DEMO day to a later date this year. The DEMO day on March 16 in the Biosintrum is therefore unfortunately canceled. 

In total almost 100 people registered to be present at this DEMO day. A fantastic number that we at BeStart are extremely proud of. But we don’t want to take any health risks and that’s why we decided to organise the afternoon at a later time. We expect this to be in June when hopefully the Corona virus has left our country. Of course we will send you an e-mail as soon as we know what the new date for the DemoDay will be.

During the DEMO day, besides the closing of BeStart 4, the selection moment for our new batch of startups was planned. We will organise this selection in a smaller committee later in March, so that the program can still start in April and we will therefore not be delayed.

Thank you for your understanding!

Kind regards

Acquaint B.V. and Foamplant are fast growing companies now, also thanks to the excellent business climate around circulair economy in the north of the Netherlands. Are you a start-up with tech that contributes to the environment, water availability or energy saving? Then it is a really good idea to listen to this podcast and register for our accelerator programme before March 1st!

BeStart worksession January 20th: demo at recycling station Omrin

Monday January 20th our startups had their worksession at Omrin in Heerenveen.

In the moring they had a peek (and sniff 😷) at the recycling station in Heerenveen. CEO John Vernooij (also our chairperson) told them his entrepeneur story with some strong advice:

‘Know what is your focus and what not. Be the best in your field. And whatever happens, there is always a plan B’

One of the startup CEO’s Linda Dijkshoorn commented it as “Best tour of the year. Companies like Omrin turn our current lifestyle to a more sustainable one by recycling and treating our waste in an incredibly innovative manner. But my Lord, we should ban single use plastics… it is scary to see how much is thrown out….”

In the afternoon Martin Tietema, who participated in our programme in 2017-2018, told our startups about the growth of his company Foamplant and the challenges he faced leading his company it to success. More about his company in this radiopodcast!

Next stop: Annemieke Mintjes and storytelling on February 10th. Looking forward to it!
