Once More was developed by Sodra and it consists of a process that is able to recycle a blend of polyester and cotton at an industrial scale. The Once More dissolving pulp consists of one part of recycled textile waste and one part of sustainably managed wood.

Problem

About 100 million tons of textiles are produced each year, but only a very limited percentage is recycled.

Solution

Once More is able to recycle white cotton (50% minimum) and polyester blends with up to 5% of viscose or lyocell traces.

Outcome

The outcome of the Once More process is a high-quality dissolving pulp that can be used for the production of new textiles. Its quality is equal to the dissolving pulp used for viscose and lyocell. The Once More technology was launched in 2019 with 3% recycled content, now is currently using 20% of recycled content, which aims to become soon 50%.
