"ReTyre's unique 'carbon-neutral' tire tech looks set to make big inroads in performance and real-world availability, thanks to a new development partnership with Vittoria and a fresh round of venture capital investment. Together, the funding and Vittoria collaboration will help ReTyre expand production of their pioneering sustainable tires. And it signals a shift from making tires for less-demanding applications like kids' bikes and strollers, stepping up to make durable, high-performance eco tires for everyday urban and commuting bikes and ebikes."
"Their patented and tightly-protected process essentially boils down to continuous manufacturing, where they injection mold a mix of recycled, reclaimed & bio materials over a strip of fabric fed through a machine to create a really long roll of tire casing. The same with the recycled & reclaimed thermoplastic elastomer that makes up the tread, continuously injection molded onto the casing. Only then, their automated machines close & bond the loop, creating the final tire in the diameter needed."
"The next piece of the eco puzzle is that ReTyre can produce the basic building blocks of their tires in bulk in one (or multiple) central locations. Then, they can use smaller and more flexible local manufacturing facilities to complete the construction of the tires, nearer where they are needed with much less waste. Ultimately, ReTyre hits their zero-carbon footprint by upcycling waste and employing carbon-negative algae captured in the restoration of damaged aquatic ecosystems."
ReTyre manufactures carbon-neutral, fully recyclable bicycle tires using a patented continuous injection-molding method that forms a long casing roll and molds recycled thermoplastic elastomer tread onto it before closing and bonding the loop to final diameter. The process uses recycled, reclaimed and bio materials plus carbon-negative algae captured during aquatic restoration to achieve a zero-carbon footprint. ReTyre centralizes bulk production of tire building blocks and then finishes tires in smaller local facilities to reduce waste and logistics. New venture capital funding and a development partnership with Vittoria enable scale-up into durable, high-performance tires for urban bikes, commuters and e-bikes.
