Under Sustainable Cities, we tackle the problem of pollution and waste prevention in water by leveraging technology to create more deliver greater effectiveness in waste management operations in water. BluePhin is a smart robot that can collect floating aquatic waste in commercial water bodies (e.g. marinas, canals, lakes, lagoons, rivers..). It runs on a combination of a battery and solar power. We've also utilized artificial intelligence to make streamline our operations. By doing so, we can prevent waste from drifting into the ocean, we prevent plastic from breaking down and emitting carbon during the process to preserve our marine ecosystem. This reduces the city's environmental impact on climate change.
