再生製造不是夢：看挪威如何做

從挪威到蒙特雷：Retyre 如何用「可回收輪胎」重塑自行車產業鏈？

在美國加州舉辦的 Sea Otter Classic，是全球單車愛好者與品牌每年必朝聖的盛會。高速競賽、極限技術與高性能零組件往往主導展場氛圍，而在這片萊卡戰甲與碳纖維競技的海洋中，一家來自挪威的輪胎公司卻選擇另闢蹊徑，以一項幾乎無人關注的「環保創新」為主打，低調地吸引關鍵產業鏈的目光。

From Norway to Monterey: How Retyre Is Reinventing the Bicycle Supply Chain with Recyclable Tires

At the Sea Otter Classic in California - a mecca for global cycling enthusiasts and brands - the spotlight typically shines on high-speed races, extreme gear, and cutting-edge components. Amidst this sea of Lycra kits and carbon fiber frames, a small Norwegian tire company quietly captured attention with something far less flashy: an environmental innovation few had thought to pursue.

這家公司名為 Retyre，其核心產品是使用天然生物基彈性體製成、可回收、無毒、無石化成分的注塑成型輪胎。這種輪胎雖看似平凡，卻可能為整個中低價位的自行車與嬰童運輸設備市場，帶來一場靜悄悄卻深遠的永續革命。

That company is Retyre, and its flagship product is a recyclable, non-toxic, petroleum-free bicycle tire made from bio-based elastomers via injection molding. What may seem like an unremarkable tire could, in fact, ignite a quiet but far-reaching sustainability shift across the mid- to low-end bike market - and beyond, into children’s transport and micromobility solutions.

【一場不靠炫技的綠色突襲】

Retyre 的攤位在 Sea Otter 展場上並不顯眼，也難以吸引那些追逐極限性能的騎士，但品牌的策略明確：它要的是量，不是速度。換句話說，它的目標不是奢華碳纖公路車用戶，而是兒童腳踏車、嬰兒推車、自行車拖車與通勤型電動車的大宗 OEM 市場。

A Green Disruption Without the Hype

At Sea Otter, Retyre’s booth was modest - easy to overlook in a crowd chasing performance extremes. But that’s by design. Retyre isn't targeting high-end carbon road bikes. Its sights are set on scale: children’s bikes, strollers, bike trailers, and commuter e-bikes. In other words, the mass-market OEM segment that’s long overdue for a low-carbon overhaul.

「我們知道自己不是主打高端市場的那一群，但我們正在進入最需要規模化、可負擔與低碳製造的領域，」Retyre 北美業務經理 Jason Rico 表示。

這背後的技術關鍵，在於 注塑工藝（injection molding）——不同於傳統硫化橡膠輪胎製程，這種技術能夠以更少空間、更低資本投入建立生產線，並且可完全回收再製成新輪胎。

【輪胎也能循環再製？】

傳統自行車輪胎因為硫化處理難以回收，最多只能「升級再利用」（如做成人造木板等次級產品），但 Retyre 的材料設計從源頭開始「循環導向」，採用可自然分解與再熔化成型的生物基彈性體，不僅無毒，還具有輕量、高抓地力與高耐用性。

根據品牌估算，這樣的製造流程可較傳統輪胎生產減少 65% 至 82% 的溫室氣體排放，若在區域市場本地製造，更能減少運輸碳足跡與供應鏈風險。

“We know we’re not part of the premium racing crowd,” says Jason Rico, Retyre’s North America Sales Manager. “But we’re entering the space that most needs scalable, affordable, and climate-smart solutions.”

The key lies in injection molding, which - unlike traditional vulcanized rubber tire manufacturing - allows for smaller, lower-cost production setups and full recyclability of used tires into new ones.

Can Bicycle Tires Really Be Circular?

Traditional bike tires are notoriously hard to recycle due to vulcanization, often ending up as low-value "downcycled" materials like synthetic boards. Retyre, however, designs its tires with circularity from the start, using a bio-based elastomer that’s non-toxic, biodegradable, and re-moldable.

The result: tires that are lightweight, grippy, durable, and yet fully recyclable. Retyre estimates its process can cut greenhouse gas emissions by 65% to 82% compared to conventional tire manufacturing. Localized production offers additional benefits - reduced transport emissions and lower supply chain risk.

【小廠房，大戰略：在地生產才是終極 ESG】

值得注意的是，Retyre 預計在 2026 年於美國中西部設立首座美國工廠。這座佔地僅 1,000 平方公尺（約 300 坪）的小型廠房，理論上年產能可達 120 萬條輪胎，遠低於傳統硫化輪胎所需的高能耗、大資本投入。

「我們的核心就是『在地生產』，這不僅能更快反應客戶需求，也讓永續不只是產品本身，而是整體供應鏈設計的一部分。」Rico 強調。

Retyre 模式的潛在意涵值得深思：當許多企業還在尋找碳中和解方時，它已開始搭建一個模組化、去中心化、近地生產（nearshoring）的循環經濟製造網絡。

Small Footprint, Big Vision: ESG Through Localization

Perhaps the most strategic piece of Retyre’s plan is its commitment to onshore manufacturing. In 2026, the company plans to launch its first U.S.-based factory in the Midwest - a compact 1,000-square-meter facility (about 10,700 square feet) with an annual output capacity of 1.2 million tires.

“Local production is at the heart of our model,” says Rico. “It’s not just about greener products - it’s about designing a sustainable supply chain from the ground up.”

What Retyre offers is more than a green tire - it’s a modular, decentralized, nearshored manufacturing network that may redefine how the industry thinks about climate responsibility and production efficiency.

【下一步：從嬰兒車到電動車】

Next Stop: From Baby Strollers to EVs

Retyre is already working with brands like Thule in the trailer and outdoor equipment space, and is actively expanding into the e-bike, electric scooter, and children’s mobility markets. The next frontier? Automotive and motorcycle tires - a tougher nut to crack, but one that aligns with the company’s Nordic-inspired mantra:

目前 Retyre 已與 Thule 等拖車與戶外設備品牌合作，並持續拓展至 e-bike、電動滑板與兒童車市場。下一個目標，則是汽機車輪胎的市場切入——這或許是更艱難的關卡，但對 Retyre 來說，正好呼應了那句北歐式的慢哲學：「我們不需要最快，只要夠穩、夠綠，並且準備好了。」

“We don’t need to be the fastest. We just need to be steady, green, and ready.”

在交通轉型與永續供應鏈重新配置的浪潮中，也許下一場輪胎革命，不會從 F1 賽道開始，而會從你孩子的第一台腳踏車出發。

As transportation systems transform and sustainable supply chains are reconfigured, the next big tire revolution may not begin on an F1 track - but with your child’s very first bicycle.
