The data on textile waste is stark – and it points squarely at sorting and recycling technology as the missing link.
Textile waste is one of the fastest-growing waste streams in the world, and the statistics behind it are sobering. A single garment can contain multiple fibre types woven or knitted together, plus zippers, buttons, elastic, linings and printed designs – each potentially made from a different material. Unlike a glass bottle or an aluminium can, which are made from a single, easily identified material, a garment is often a composite product disguised as a simple object – and that complexity is reflected directly in how little of it ever gets recycled.
Every year, tens of millions of tonnes of clothing and household textiles are discarded worldwide, and the overwhelming majority of it ends up in landfill or incineration rather than back in the production cycle. Despite growing awareness of the problem, collection rates for used textiles remain low in most regions, and even among textiles that are collected separately, only a fraction are suitable for direct reuse as clothing.
The environmental cost of this waste is significant. Textile production is resource-intensive – growing cotton requires large amounts of water and pesticides, while synthetic fibres such as polyester are derived from petroleum. When discarded textiles end up in landfill, all of the resources invested in producing them are lost, and synthetic fibres can take decades to break down, while natural fibres in landfill conditions can release methane as they decompose.
For the textiles that do get recycled, the next stage depends on fibre composition. Cotton and other natural fibres can go through mechanical recycling, where garments are shredded and pulled apart into individual fibres for use in coarser yarns or non-woven applications such as insulation, padding and industrial wipes. Polyester and other synthetic fibres can, in principle, be recycled through chemical processes that break the polymer down to its monomer building blocks for repolymerisation into virgin-quality fibre – though these processes depend heavily on receiving feedstock with known, consistent fibre composition.
This is the gap that PICVISA's ECOSORT TEXTIL system is designed to close, using near-infrared sensors to scan and classify textiles by fibre type at industrial speed – identifying cotton, polyester, wool and various blends, and sorting accordingly. By providing recyclers with consistently sorted, well-characterised input streams, automated optical sorting helps turn the textile waste statistics around, supporting the growth of both mechanical and chemical recycling routes for the millions of tonnes of textile waste generated each year.
