Recycled Rubber
Ground tyre and offcut rubber reused in soles, mats and surfacing.
What it is
End-of-life tyres and factory offcuts are shredded into crumb rubber and rebonded into flooring, mats, playground surfacing and shoe outsoles.
Why it matters
Roughly a billion tyres reach end of life each year; recycling them displaces virgin rubber and avoids stockpiles and burning. The open question is what the original rubber contained — tyre crumb carries zinc, PAHs and 6PPD residues.
Upsides
- Diverts a huge, hard-to-dispose waste stream
- Very durable in flooring and outsole applications
- Displaces virgin synthetic rubber production
- Widely available and low cost
Trade-offs
- Tyre crumb can carry PAHs, zinc and 6PPD residues
- Not suitable for food contact or infant products
- Can off-gas odour indoors when new
What to look for on the label
Third-party emissions testing for indoor use, non-tyre (offcut) sources for sensitive applications, and stated recycled percentage.
Better or comparable alternatives
Compare recycled rubber in a finished product
Material choice is only part of the decision. The same material can appear in very different products: compare composition, expected use and end-of-life options before treating it as a better replacement.
- Composition and sourcing
- Use the label guidance above to check the actual percentage of recycled rubber, any blends, coatings or adhesives, and which component a certificate covers. A claim about one input does not describe the whole product.
- Use and maintenance
- Weigh the listed upsides and trade-offs against the job you need it to do. Check care instructions, repair options and whether a comparable item you already own could serve the same purpose.
- Disposal in your area
- Ask your local collection service about the finished item, not just its main material. Blends, coatings and attachments may change how it can be collected. Do not assume a recyclable or compostable claim applies to your household system.
Frequently asked
Is recycled tyre rubber safe for playgrounds?+
It is widely used and studies mostly find low exposure risk, but several regions are moving away from crumb infill. Cork or wood-fibre surfacing avoids the question.
Can recycled rubber be recycled again?+
Bonded crumb products are difficult to reprocess. They extend the life of the material rather than closing the loop.
