Retein’s mission.

Retein’s mission is to accelerate the transition towards a material-optimized world with the use of nature-inspired technologies.

Our mission is to bring together technology, innovation, and collaboration in service of a sustainable future for all. Using cutting-edge research and development, we recover valuable materials for various industries by reusing waterborne resources. We are committed to reducing industrial carbon footprint and protecting the environment through efficient materials usage. We harness valuable resources from water in a sustainable manner, making available a consistent supply of clean water and valuable nutrients, metals, and other components in order to support humans, animals, plants, and industries in any given location.

Retein’s vision.

As a company, we are committed to leading the way in creating a future where humanity is a net-positive to nature. Where our nature-inspired solutions serve the needs of humans, animals, plants, and industries.

We recognize the responsibility we hold towards future generations, and we are determined to meet their needs in a responsible and sustainable manner. With our innovative approach and collaborative mindset, we aim to not only be effective but also environmentally friendly and economically viable. As a leader of this change, we will leave a positive impact on the planet and ensure a better future for all.

Our values.

Rooted in our academic background with our hearts and DNA, we prioritize academic rigor and accountability, placing a strong emphasis on thorough research.

Trust through transparency.

As transparent as water is, pollution may be lurking beneath the surface. Dare to be vulnerable and surface pollution as soon as you sense it. The trust we build through transparency lifts us all higher than we could rise alone.


Curiosity is in our DNA. We’re not afraid to try, because we are confident that our failures will make us better. We’re curious in others and welcome diverse perspectives.


We prioritize sustainability in every aspect of our operations, from promoting sustainable work conditions to fostering positive relationships with our stakeholders, and conducting sustainability-driven business.

Making a difference:

Our underlying driving force is a passion for improving our planet and the lives of people.

Celebrating the outcome:

We promote outcome-based working to be productive not only in the short term. World-leading performance in a sustainable fashion. 

Have fun. Seriously!

The average person will spend over 90,000 hours of their life at work. Terrifying? Not at all. If those hours are filled with meaning and fun. We believe that making the world a better place should be lots of fun!

    Our name.

    A journey of meanings.

    Our company name is a compelling story in itself. “Retein” is derived
    from the merge of the verb “retain” and the noun “protein” and it is a
    singular linguistic unit that encapsulates both connotations. “Retein” is
    still pronounced similar to “Retain”.
    “Retain” expresses our commitment towards a holistically sustainable
    future, which begins at the molecular scale. We effectively recover
    valuable building blocks from water, via deployment of specific proteins
    that perform nature’s finest separation. Our technology helps preserve
    and retain the treasured elements that reside in water, which in itself is
    one of our planet’s most valuable resources. Therefore, we could not
    conclude with a more fitting name for our company.
    Proteins are a group of biomolecules that perform versatile tasks, which
    in many cases are essential for life. The magnitude of their importance is
    perhaps expressed by the word “protein” itself, coined by the Swedish
    chemist Jöns Jacob Berzelius in the summer of 1838.

    It is derived from the Greek word πρωτείος which means ‘primary’ or ‘of the highest
    importance’. By adding a different ending, Berzelius shaped the word
    protein which means ‘the most important building block in a thin thread’.
    Our company leverages the building blocks of life to sustainably retain
    key building blocks for a thriving planet, where humanity is a net-positive
    to nature.
