Catifa Carta's shell is crafted entirely from PaperShell, a groundbreaking material derived from paper. Comprising 29 sheets of paper bonded with a natural resin binder, Catifa Carta significantly reduces the chair's environmental footprint by retaining carbon dioxide originally captured by trees. Paper used to produce PaperShell is sourced responsibly, utilizing residues from Swedish wood production such as sawdust, chips, and branches.

At the end of its lifecycle, Catifa Carta can undergo pyrolysis, a burning process that happens in absence of oxygen and prevents CO2 release. Through pyrolysis PaperShell is converted into biochar. Biochar is a form of charcoal produced from plant matter made up of up to 90% of carbon, which locks CO2 effectively, avoiding its release into the atmosphere. Biochar is best used as soil enhancement, helping to restore the soil to its natural richness and hence supporting biodiversity, the key for a healthier and more balanced environment.
