Decades of Engineering. Proven Hardware.

We scaled it to commercial production. We sold the company. Then we scaled further into biodiesel factories in the Netherlands, Spain, and Canada. We built them. We ran them. We exited successfully.

We did not build software. We built hardware. And we proved it works.

StikstofAlgen beursstand met 1,2 meter algenbuizen, HDPE U-bochten en 316 RVS flenzen voor stikstofreductie uit mest.

But we did not stop there.

We scaled algae into industrial biodiesel. Factories in three countries. Proven track record.

Now, we point that exact same hardware at the Dutch manure crisis. The tubes are still 1.2 meters. The 316 stainless flanges are still the same. The CO₂ injection, the degassing nipples, the automated sponge cleaning—all still the same.

Only the feedstock changes. From biodiesel to manure. From fuel to feed.

1,2 meter diameter algenbuis van StikstofAlgen - de universiteiten zeiden 20 cm, Hans bouwde 120 cm en bewees dat het werkt.

The Universities Said 20 cm. I Built 120 cm.

Remember 25 years ago? The experts said 1.2-meter algae tubes were impossible. Light penetration, they claimed. Turbulence, they said.

I built it anyway.

One year later, I was on the cover of Biodiesel Magazine. Two years later, CNN was filming my factory. Three years later, I sold the company successfully.

The experts were wrong. I was right. Now I am 75, and I am doing it one more time.

We Have Proven It. Now We Build It for the Dutch Farmer.

I have started companies from scratch and exited successfully—multiple times, across multiple industries. But I am not a consultant. I am an engineer who builds things that work.

We have built and sold:

Algae Biodiesel (2005): The first 1,2-ø diameter algenbuizen systeem. Against all academic advice. Sold successfully.
Biofuel Factories (2005): Manufactured in the Netherlands, Spain, and Canada. Multi-million exit.
Cover of Biodiesel Magazine. CNN. Canadian TV. Dutch TV, and many others. The proof is in the footage.

It is on the news every single night. I am building it one last time—not for a stock market exit, but to SAVE THE DUTCH FARMER from the forced buyout.

The Next Boom Is Not a Bubble. It Is the Nitrogen Crisis.

While others chased crypto and cannabis, I built industrial bioreactors.

The manure crisis is not going away. Importing meat and soy from Brazil is not a solution. Exporting the problem is not a solution.

The solution is 1.2 meters of flowing algae, powered by the farm's own biogas, cleaning the manure on-site, and turning it into high-protein feed and clean water.
