“…Glass recycling is far less straightforward than it appears [ 1 , 2 ]. The use of a cullet as a feedstock for the fabrication of original articles by remelting cannot always be applied [ 3 , 4 ]. Some glasses, in fact, are ‘unrecyclable’ for several reasons, including the risks of degradation of their properties or the loss of chemical purity [ 5 ].…”

Additive manufacturing (AM) technologies enable the fabrication of objects with complex geometries in much simpler ways than conventional shaping methods. With the fabrication of recyclable filters for contaminated waters, the present work aims at exploiting such features as an opportunity to reuse glass from discarded pharmaceutical containers. Masked stereolithography-printed scaffolds were first heat-treated at relatively low temperatures (680 and 730 °C for 1 h) and then functionalized by alkali activation, with the formation of zeolite and sodium carbonate phases, which worked as additional adsorbing centers. As-sintered and activated scaffolds were characterized in terms of the efficiency of filtration and removal of methylene blue, used as a reference dye. The adsorption efficiency of activated printed glass was 81%. The 3D-printed adsorbent can be easily separated from the solution for reuse.
