Biodegradable air filters from cotton waste
Billions of air filters are discarded every year – most made of non-recyclable synthetic materials.
The fashion industry generates vast amounts of cotton waste that ends up in landfills. Cotton production is resource intense.
We are working on a formula that has shown the capacity of converting cotton textile waste into nanocellulose-based air filters that are fully biodegradable and meet high filtration standards.
Our filters will be compostable after use, helping reduce landfill loads and support circular material flows.
In collaboration with the Slovak Academy of Science, we use a patent-pending technology to extract and process cotton fibers into high-efficiency filtration sheets.
We follow the vision of creating efficient, performance-tested filters that can safely return to nature.
