Sustainable food Green Hackathon

- September 1, 2014 in Events, Featured

14884688968_112d5cc4b0_kAugust 23rd we organized a Green Hackathon in Stockholm, back at the reactor hall where the first Green Hackathon was hosted. The focus of the hackathon was sustainable food. We invited developers, researchers, designers, retailers, food producers, to get together and prototype solutions for a more sustainable food system. This time the event was organized as a preconference activity to ICT4S, an international conference on the use of ICT for sustainability, and it was organized by the Centre for Sustainable Communications at KTH, as part of the project From Data to Sustainable Practices, in collaboration with COOP Sverige and supported by OKFN Sweden & Open Sustainability WG. Me and Jack Townsend from the sustainability working group participated.

The starting point of the event was that food production and consumption have become a major driver behind environmental degradation, such as climate change, biodiversity loss and degradation of land and freshwater. Agriculture must be transformed to be sustainable and must deliver sufficient amounts of food for the growing population (both through increased efficiency and dietary changes) and also cut greenhouse gas emissions; counteract biodiversity loss; reduce water use and phase out pollution from agricultural chemicals.

14884640070_2714428b33_kThe participants of the hackathon were a mix of researchers, designers, programmer, problem owners and innovators. The keynote was followed by a time for team building and networking time, with “speed dating” to get the participants to know each other and their respective field of expertise and to generate ideas. After some ideas crystallised into groups, the hackathon started and the groups had around seven hours to build their concepts and prototypes.

The Green Hackathon was located at R1, the dismantled underground nuclear reactor hall under KTH campus in Stockholm.

The Green Hackathon had two winners looking at how to reduce the amount of food waste:

Eat Exchange

Eat Exchange is a mobile application, which allows local community to share food that would have been wasted. The application would enable individuals to advertise the food that they wouldn’t be able to consume. Then the supply of spare food would be collected by the members of the community who would otherwise need to buy it.

Last Minute Food
