Rezero develops material solutions by recovering pre-consumer cigarette filters made of cellulose acetate, giving them a second life. The company has developed an innovative strategy to value a material that would otherwise be incinerated, achieving mechanical performance and aesthetic qualities for product design comparable to those made of virgin acetate. Depending on the targeted material output, the transformation process follows two distinct pathways, resulting either in Re-fil® fibers or in pellets obtained through filter shredding followed by compounding with plasticizers and pigments. The facility also offers a sheet format, in which the fibers are isolated and subsequently converted into sheets. The material can be applied across different sectors. The fibers, for example, can be used as-is for sound absorption panels, padding/wadding, filtration. The pellets are versatile for injection molding, enabling the creation of fashion items such as small parts and hardware components. Finally, the sheets are ideal for crafting eyewear frames, accessories, and custom-cut designs.
