The document discusses a GrowSmarter project that aims to implement integrated waste collection infrastructure in European cities. Specifically, it presents on smart waste collection technology that transports waste through underground pipes to a central location, turning the waste into energy. The technology was tested in a residential area with 300 households in Stockholm, reducing waste truck traffic by 90% and CO2 emissions by 70%. Results and plans for replicating the system in other cities are also summarized.
