Our journey began in 2005 with our first biodiesel refinery and manufacturing plant in the Netherlands.

Soon after, we built similar factories in Spain and Canada, where we designed and constructed plants for the production of industrial green fuels. Our equipment was sold and installed worldwide.

We realized complex technical processes and found practical solutions for thermal challenges. For us, it has always been about performance, reliability, and scalability.

Three decades of expertise. Three continents. Complete biofuel refineries and commercial algae installations – delivered to clients around the globe

We produced complete biodiesel installations – skid-mounted and containerized

No planned obsolescence. Only decades of reliability.

Where We Are Now

Today, our team works from multiple locations across Europe. We are engineers. We build what works. And we stand behind what we build.

Our engineering expertise has solved complex thermal challenges for years. Today, we apply the same precision, the same integrity – to a new mission: portable, low-tech KonTiki kilns that turn sargassum, farm waste, and forestry slash into valuable biochar. No smoke, no power, no expensive plasma. Just a simple, trailer-mounted flame‑cap kiln that works anywhere.

Robust. Simple. Honest.

That is not just our philosophy.
That is our guarantee.

Ready to put our engineering to work for you?

We bring decades of industrial experience to deliver reliable, efficient, and affordable biochar solutions – for coastal communities, farms, and waste managers who need results, not hype.

Same leadership. Same engineers. Same drive.
