Ouagadougou: Student Rasmata Simporé, from the Doctoral School of Computer Science Applied to Climate Change at Joseph KI-ZERBO University, a research program actively supported by WASCAL, presented an innovative technological solution called 'Trash App,' designed to modernize urban waste management and contribute to the sanitation of Burkina Faso's cities, particularly in the fight against diseases.According to Burkina Information Agency, the integrated system developed by Simporé consists of a mobile application called 'Trash App', a web application, and a smart sensor that sends the location and fill level of the bins to the central level, enabling collectors to efficiently gather waste. Simporé emphasized that waste management remains a major concern in the cities of Burkina Faso, which motivated her to propose a solution beneficial for her city and the country as a whole.The tool is designed to facilitate interaction between various stakeholders in waste collection, from production to recovery, allow ing collectors to plan their rounds based on real needs. The innovation will also enable citizens to express their opinions, report violations, request services, and identify structures responsible for waste collection. Furthermore, the application will provide decision-makers with critical statistics and information on waste management.The jury, impressed by the technical quality and practical utility of the solution, awarded Simporé a score of 18/20, recognizing the innovative and promising approach. Her thesis director, Dr. Belko Abdoul Aziz Diallo, highlighted the initiative as a "true ecosystem of smart solutions," capable of significantly improving waste collection regularity and reducing unsanitary conditions in neighborhoods. The platform is expected to optimize waste collection and enhance community participation in environmental preservation.Mr. SIENOU Adama, head of the waste collection and sorting service at the Ouagadougou city hall, praised the initiative and revealed that the municipality i s considering a pilot project to test the solution in a targeted area of the city, with potential for expansion based on its effectiveness. This innovation represents a step towards modernizing urban services and combating diseases associated with unsanitary conditions.Simopré completed her master's degree at Joseph KI-Zerbo University's Doctoral School of Computer Science Applied to Climate Change with funding from WASCAL, under the theme of integrating information and communication technologies and the Internet of Things for waste collection management and citizen engagement in Ouagadougou. The jury overseeing her project included Pr Alfa Oumar DISSA, Dr Belko Abdoul Aziz DIALLO, Dr Kisito KABORE, and Dr Didier BASSOLE.
