As part of this validation and following continuous process improvements after each of the first 3 Phase-one batch tests, the Pilot Plant achieved a key objective:\n \n the production and collection of substantial quantities of white powder material—potentially fumed silica—in the dedicated product recovery unit, commonly known as the \"baghouse.\"\n \n\n\n\n\n Image 1) Sample of material produced during the test\n \n\n\n In its May 13th, 2025, press release, PyroGenesis emphasized the importance of this development:\n \n\n\n\n “...producing and then collecting fumed silica from the product recovery unit, known as the ‘baghouse,’ confirms most of the underlying assumptions that the process can make, as expected, fumed silica at commercial scale. This is what makes this milestone probably one of the most, if not the most, important milestones in the entire process. Having overcome all the challenges to get to this point, then the remaining balance of challenges should be very manageable.”\n \n\n\n This achievement is another step in validating the potential of HSPI’s proprietary process to produce commercial-scale fumed silica, effectively positioning the Company’s next phase of development and eventual commercialization....
