This boat design is nicknamed the "Ideonella Warden" as it uses the bacteria Ideonella Sakaiensis to break down the plastic also using the FAST-PETase enzyme to massively speed up the process. It uses a plow to ease movement through the garbage patches and absorb the plastic to be processed. All waste is collected to be processed adequately. The boat is also solar powered for minimum environmental impact.
