The 10th annual GPPN Conference, hosted by the Sciences Po School of Public Affairs, featured students' solution oriented ideas and prototypes to address public policy challenges identified by the UN Sustainable Development Goals (SDGs). To participate, each GPPN member school carefully selected up to five student teams to present their projects and compete for the GPPN prize. The result: 32 teams from around the world met in Paris to showcase their ideas on how to solve some of the most pressing global challenges of today.
Our proposal is four-pronged. First, we recommend local governments to charge food waste collection by making households purchase designated rubbish bags for different categories of waste, including food waste and general combustible waste. To provide incentives for households to separate their food waste from general waste properly, bags for food waste are cheaper than the ones for general combustible waste. The separated food waste is to be disposed of at smart bins that we call “eco-bins”. Similarly to what is in place in certain districts in Seoul, households will need to scan their waste ID cards to open the bins to deposit their food waste. The “eco-bins” will then measure the weight and/or volume of each bag, and this data is stored. Second, this data will be linked with each household waste ID card. Third, we suggest local governments to implement a point system to incentivize households to separate and recycle their food waste. Last but not least, the food waste collected from the “eco-bins” is recycled into fertilizers, bio-gas, electricity and/or animal feed, depending on local conditions and demands.
