Trailblazers: It’s the concerted effort to search for alternatives as well as
the improvement and creation of recycling methods
that makes SOEX such a unique player in the industry.

Pioneer thinking: SOEX developing and implementing recycling methods for extracting secondary raw materials with the goal of upholding our ‘zero waste’ philosophy to the greatest extent possible.

That’s why SOEX works together with partners in the textile industry and elsewhere towards creating a future in which resources are no longer wasted and raw material extraction, production and recycling are sustainably and economically intertwined.

Footwear recycling

More than 20 billion pairs of shoes were produced worldwide in 2015. However, according to the most recent data, no more than 5% of all used shoes around the world are collected and recycled (source: Recycling International).

SOEX therefore worked with various partners to develop a footwear recycling facility. The plant processes all types of footwear and separates these into various components. Some of these secondary raw materials can then be reused in the manufacture of other products.

Feel free to contact us if you have any questions about the use of individual secondary raw materials, would like to know the technical specifications or if you would like to request samples!


SOEX led the RESYNTEX project (2015-2019), a €9 million research endeavour for the EU with the goal of chemically treating old textiles to convert them to secondary raw materials. Our task was to implement a method of automatically separating second-hand clothes of the same material, which is a necessary step towards industrial chemical recycling. In May 2019 occurred the installment of a pilot semi-automatic separator system for used textiles, located in the SOEX plant in Wolfen, Germany.


RESYNTEX is a cooperative project consisting of 20 partners from ten different EU member states. The partners include industrial associations, companies, SMEs and research institutes. The group is working together to develop an effective model for the entire value chain.
