Most of our clothing contains polyethylene terephthalate (PET) fibers, a common form of plastic. Recouping PET fibers from discarded clothing, however, can be costly and toxic, often releasing forever chemicals found in the fabric. But researchers have developed a sustainable way to upcycle textile waste by directly incorporating clothing scraps into a synthesis for metal-organic-frameworks (MOFs). • The PET-to-MOF pipeline is not a new area of study, but a typical MOF synthesis can require very high heat, very high pressure and harsh solvents. This new synthetic pathway can be done at room temperature with eco-friendly solvents. It also turns the MOF superhydrophobic. This well-known MOF, UiO-66, is typically a brittle, hydrophilic substance. But spandex fibers in the fabric functionalize UiO-66 to be completely water resistant. This results in a waterproof coating that can adhere to textiles. Since most waterproofing methods rely on fluorinated chemicals, which are harmful to both the environment and humans, this work provides a sustainable way to create MOF-based, waterproof coatings and to give old clothing a new life. • Read the paper: https://doi.org/10.1021/acsami.4c10459 • (Corresponding author: Juan P.
