During their summer school KIC InnoEnergy Benelux and the masters programme ‘Energy for Smart Cities’ handed out a master thesis price. With the goal to stimulate innovation and entrepreneurship among future game changers, an award for best master thesis on innovation and entrepreneurship was handed out. In order to apply, the students had to send in a video summarising the topic and outcome of their master thesis.
‘Energy for Smart Cities’-student Rafael Salcedo won the first price with his thesis about optimising the waste collection system in Stockholm. After analysing the waste system, Rafael made two observations: 1) because of different kinds of vehicles and companies handling the waste, the current system causes traffic ingested streets; 2) as a result of this, air pollution is getting worse and worse. So just how efficient is this system? During his research, Rafael optimised the routes of waste collecting companies. “These routes were obtained after processing big data from the city and using open source heuristic software.” says Rafael. Tracing them in a more distance and time efficient way, he calculated the savings using the updated system. “Reorganising the waste collection system in Stockholm, you could potentially achieve 50% savings in the system in terms of distance and time travelled. This is reflected directly into costs and CO2 emissions.” concludes Rafael.
