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 by 96.6% compared to conventional farming, and consequently contribute towards the alleviation of water shortage.
