carbon negative food-waste

    Can carbon negative technology be brought to the index of the consumers? Carbon dioxide levels has surpassed a prehistoric level of 400ppm. This project started from our need to reduce the concentration of carbon in our atmosphere through changing the way we consume in our society today. There is a lot of talk of carbon negative technology but "we", as ordinary consumers, don't see any of it. I questioned whether we could bring it closer.
    Global food waste is a major contributor to green house gas emission. As food is transported to landfill they begin to decompose and release methane which has 25 times global warming potential over carbon dioxide. The daily fuel costs for carrying this food-waste through cities adds onto the total weight of food-waste's environmental impact.

    Through an anaerobic combustion process called pyrolysis, this food-waste can be converted to char. The process allows for the methane to be combusted, thus producing a less harmful greenhouse gas. Since this process produces char, it means that a proportion of the carbon in the food remains in solid form. This can be used as soil enhancement, by taking advantage of its porous properties for microbial community growth. This enhanced growth of microbial community in turn allows for breakdown of further carbon dioxide in the air and turned into solid, allowing for more carbon to be removed from the carbon cycle. This a carbon negative technology can be brought to consumers!

  Yuki is an Innovation Designer and Technologist working on creating products and experiences that create positive futures. He is a Design Researcher at the EPFL+ECAL Lab, where he is working on Digital Innovation to bring emerging technologies from the research labs at EPFL to people who need it. Yuki is a graduate from the Royal College of Art and Imperial College London, holding an MA and MSc in Innovation Design and Engineering and an MEng in Mechanical Engineering. He is currently pursing a Masters of Advanced Studies at EPFL and ECAL in Design Research in Digital Innovation. He is passionate about using Design Thinking and Human Centred Design to create positive impact. Since his childhood he was inspired by technology and design. He is also interested in start-ups and getting new ideas to market. He is a Design London Fellow, which allowed him to attend Executive MBA lectures at Imperial Business School and to work on projects along side MBA students. With the Lines team he was fortunate to attend the European Innovation Academy and the Intel Make it Wearable Challenge to learn about patents, marketing, business and design.
