Addressing Global Challenges

  • Water Recycling

    Collection and Reuse of Transpiration Using Air Conditioning

    Due to population growth and industrial development, water consumption is projected to increase into the year 2050. As a result, more than 5 billion people are estimated to have challenges in accessing fresh water. Our technology allows for the reduction of water usage necessary to cultivate 1kg of lettuce to approximately one percent of conventional farming, and consequently contribute towards the alleviation of water shortage.

    High Yield and High Standards of Hygiene

    Our lettuce boasts a very high yield rate, compared to the 50~60% yield rate of conventional farming, leading to great reduction in food loss. Furthermore, our high hygiene standards ensure extended freshness of our products, contributing to reduction of food waste as well.

Towards a Sustainable Future

  • Vertical Farm Educational Tours

    Vertical Farm Educational Tours

    We provide educational factory tours for schools and educational institutions. During these tours, children and students not only have a possibility to observe firsthand our vertical farm operations but are also exposed to and given an opportunity to think about global food and agricultural issues.
