DoubleBio – Bio-based and biodegradable textiles

The DoubleBio project intends to develop a textile fiber that is both bio-based and biodegradable, in sea and land. The fiber is expected to be particularly useful in disposable textiles such as agricultural textiles, packaging, wet wipes, diapers, and face masks.

These products are usually based on non-degradable fossil-based polymers such as polypropylene and polyester. In Sweden, much is recycled through energy recovery. In many European countries landfill is more common, some of these products end up in drains, nature, and the sea.

A biodegradable textile would contribute to a better environment by avoiding littering, microplastics and enable composting. In this project, the textile fibers will be produced by melt spinning, which is the most common fiber spinning method in the textile industry. The newly developed material is intended to replace fossil-based polymer, especially polypropylene, and thereby produce effects such as reduced net emissions of carbon dioxide and reduced occurrence of microplastics in nature.
