Five potholes — two at Mote Park and three at Penenden Heath — have been repaired with an experimental low-carbon material made from recycled textile waste, in a trial run by Maidstone Borough Council and sustainable materials company RECOOL.

The pilot is small in scale but specific in scope. It covers council-owned land only: parks, open spaces and car parks across the borough, which Maidstone Borough Council maintains. Public roads sit outside the trial entirely, since Kent County Council holds highway maintenance responsibility there. That jurisdictional split matters for anyone assessing whether this material can scale — the council's own estate is the testbed, not the road network where the tonnage potential actually lies.

The product works in two layers. Recycled textile waste fills most of the pothole, and a specialist surfacing layer goes on top. RECOOL developed the material; the council supplied the sites and the defects. Neither party has published tonnage figures for the textile feedstock consumed in the five repairs, nor a carbon comparison against conventional asphalt patching. Those numbers will decide whether this moves beyond demonstration status.

The waste stream behind the trial is substantial. Councillor Rachel Rodwell, Cabinet Member for Climate Transition and Nature Recovery, framed the pilot against the volume of discarded clothing in the UK. "While second-hand selling sites have helped extend the life of many clothes, fast fashion means huge amounts of textiles are still being thrown away every year," she said.

"This pilot is about turning that problem into an opportunity. By testing whether waste textiles can be repurposed as part of a pothole repair material, we're exploring a practical solution that could reduce waste, cut carbon emissions and support the circular economy."

Her point lands on a real policy pressure point. Separate collection of textiles will become mandatory for councils under the Simpler Recycling reforms in England, and collections for household textiles are already scheduled under the Resources and Waste Strategy commitments. Local authorities will need cost-effective outlets for the captured material. Construction and infrastructure applications — aggregate substitutes, fill materials, surfacing components — are among the few markets with the volume absorption to take significant tonnage, provided performance and cost benchmarks hold.

That is precisely what the trial is designed to test. Maidstone Borough Council will monitor the five repairs over the coming months to assess durability under normal park use and weather exposure. The council says it wants to establish whether the material offers a durable, more sustainable alternative to traditional repair methods — a claim that currently rests on five patches and one season of observation.

The distinction between built capability and proven performance is worth holding onto. RECOOL has a product. Maidstone has five installed trial sections and a monitoring programme. Nothing in the pilot yet constitutes procurement commitment, framework adoption, or a specified rollout across the council's wider estate of car parks and open spaces.

What happens next depends on the monitoring results and on whether the council converts them into a purchasing decision. If the textile-filled patches survive a British winter and a summer of park traffic, the follow-on questions are unit cost versus conventional materials, feedstock supply from textile collectors and sorting operators, and whether Kent County Council would entertain trials on the public highway. Each is a measurable milestone.

For now, the industry marker to watch is Maidstone's performance assessment at the end of the monitoring period. That report — durable or not, costed or not — determines whether recycled textile moves from parkland novelty to a specified infrastructure material.
