Beamline is running an introductory series about startups in their current Deeptech Batch. This time they deep-dived into the heart and soul of Sutu.

Here is the original Q&A session:


Tell us a bit about your startup and the problem it aims to solve. What inspired you to start this company?

Sutu’s mission is quite clear - we help to save the planet. We were first inspired by the environmental impact of single-use plastics & the EU's push to ban them. "As a nature lover and material scientist, I saw an opportunity to create a truly sustainable alternative," says Ailet Õis-Saar (CEO & co-founder of Sutu). Our dream is to replace harmful fossil-based plastics in everyday products with this eco-friendly option.


How does your technology contribute to environmental sustainability?

Sutu material is from reed, a plant that grows worldwide in coastal areas and needs to be harvested yearly anyway. So, from one side we’re doing the coastal areas a favor and from the other side, we’re providing an opportunity to produce bio-plastic products with a 13 times smaller carbon footprint compared with traditional fossil plastic.


How does your solution differ from existing alternatives in the market?

1️⃣ Unique Reed-Based Material: Our foundation is reed, a remarkable resource that we like to refer to as "Nordic bamboo." Reed grows abundantly without the need for additional land or cultivation. Unlike some bioplastics, it doesn't compete with food sources, making it a truly sustainable choice.

2️⃣ Versatility and Performance: Sutu material is biodegradable, so it won't clog up landfills or pollute our oceans as fossil plastic does. Plus, it's incredibly versatile - we can use Sutu material to make everything from cards to food containers, from cutlery to 3D filament

3️⃣ Local Sourcing and Production: Sutu's key ingredient, reed, is a globally abundant resource.


Gratitude to mentors & supporters!

Ailet Õis-Saar (CEO of Sutu) gives huge thanks for support, help, and guidance:

Aneth Tinnus, Yoad Mick, Merilyn Kesküla, Hannah Swabey, Jana Budkovskaja & Anton Ossipovski. In Ailet's words: "Your experiences and advice are invaluable."

Ailet Õis-Saar highlighted that being part of the Beamline Accelerator has been very valuable: "The dedicated people behind Beamline have opened doors for us towards new cooperation opportunities & partners. This has fueled our growth and highlighted the importance of a dedicated team and the need to maintain focus."

Goooo Sutu - we are rooting for you & your game-changer reed material! 🌿
