Less Weight. More Strength. 90% Recycled Textiles
Description
21upcycling and Foldstar Inc. introduce a new generation of lightweight construction panels made from recycled textile materials. At the heart of the innovation is an AI-optimized folded core structure that maximizes strength while minimizing material use and weight.
The result: a lightweight board that carries more, weighs less, and consists of up to 90% recycled textile fibers - materials that would otherwise be incinerated.
Designed for sustainable interior construction and modern design, this technology turns textile waste into high-performance building materials and sets a new benchmark for circular lightweight structures.
