In 2019, their AI algorithm was tested on material identification in complex settings in transfer stations. It successfully  helped improving the operations of the facility. By 2020, it became the core focus of the company as it had the potential to change how we value and pay for waste as a service forever.

Indeed, Wastack enables facilities to understand what is in the waste stream with an accuracy never reached before and it helps the facilities financially leverage this data into new revenue streams.
