From biogas to superfood: Sustenso’s circular breakthrough

Sustenso: Innovation in sustainability with biogas and algae cultivation

The horticulture sector in the Netherlands receives an impressive, circular boost thanks to the inspiring work of Sustenso from Alkmaar. This forward-thinking company converts green waste streams into biogas, significantly reducing dependence on fossil fuels. What truly sets Sustenso apart is their innovative solution for the CO₂ released during biogas production: it serves as nourishment for microorganisms, specifically, microalgae.

Eight years ago, Hans van der Weide, the founder of Sustenso, had a vision to produce biogas from green waste streams. In collaboration with Prof. Dr. Joost Teixeira de Mattos and Willem Bas, they developed a system where excess CO₂ is used for algae cultivation. This breakthrough directly connects the energy transition with a groundbreaking change in our food production system.

A fruitful collaboration

It all started with a meeting between Hans and Prof. Dr. Joost Teixeira de Mattos. Together, they brought the idea to life to use the excess CO2 from biogas production for algae cultivation. Willem Bas joined the team, and together they worked hard to realize a well-functioning biogas plant. Today, the produced biogas is directly pumped into the gas network, enough to supply a substantial residential area with gas.

Innovative algae cultivation

Sustenso’s algae cultivation is not just a side project. With a unique demonstration installation, they have proven that a direct link between CO₂ capture and algae cultivation is not only possible but also highly effective. The next step? A large-scale plant that makes optimal use of sunlight in a specially designed greenhouse. This forward-thinking approach promises a significant impact on sustainable food production.

Algae: The superfood of the future

Algae are rich in essential nutrients such as proteins, fatty acids, antioxidants, and vitamins, and will eventually be processed into dietary supplements. Sustenso even has a solution for any excess CO₂: it is liquefied and can be used as fertilizer in agriculture, creating a fully circular system.

A sustainable future

Sustenso continues to tirelessly pursue sustainable innovations. Their first project, the biogas plant, has now been sold to Engie, a leading energy company. This success story marks just the beginning of Sustenso’s impactful journey toward a sustainable future.

Through their pioneering work, Sustenso demonstrates how creative solutions and collaboration lead to significant strides forward in both the energy transition and food production. Their work is an inspiration to everyone committed to a more sustainable world.
