Design the seam to come apart.
A garment can be easy to sew and difficult to take apart. Resortecs changes the thread so a later, controlled heating process can release components before recycling.
BE BelgiumIn practice. Resortecs offers sewing threads and a disassembly process designed to work together. Suitability depends on garment construction and the downstream recovery route.
What to keep in view
Company speed and recovery claims do not establish whole-system economics, energy use or fibre-to-fibre outcomes at continuous commercial volume.
Put the release mechanism into the seam
Resortecs pairs heat-dissolvable SmartStitch sewing threads with thermal disassembly equipment. The threads are selected during manufacture and can be used with conventional sewing machinery. At the other end of the product’s use, a controlled heating process releases the seams so different parts can be separated.
The company describes a range of threads for different applications. A release temperature has to suit the product’s use and care, as well as its eventual disassembly. A seam designed to come apart must still perform while the garment is being worn, washed and repaired.
The company publicly demonstrated its first thermal disassembly prototype in Brussels in December 2021. Its launch account described a low-oxygen chamber using heat and mechanical force, distinguishing the demonstration from the wider recovery network it hoped to build.
Prepare the material for the next process
Zips, labels, linings and other components can complicate textile recovery. Opening a garment helps separate those components before the material reaches a recycler. Thermal disassembly is therefore a preparation step; it does not itself turn mixed fibres back into new fibre.
Our reading: the important decision occurs long before the waste arrives. A manufacturer must specify a compatible construction, and a recovery system must collect it and recognise how to process it. Energy use, sorting, material compatibility and the quality of the recovered output still matter. A more separable seam creates an opportunity for circular production, but the rest of that route has to exist.
