【煥發生機】Patagonia如何破解潛水服回收利用難題

從明年開始,巴塔哥尼亞公司(Patagonia)的潛水服不僅可以回收再利用,還能重新煥發生機。

這間公司的「潛水服工廠」維修和設計中心位於加州文圖拉(Ventura),距離海灘只有幾個街區,工廠的桌子上擺放著一件前所未有的潛水服。這件潛水服的外觀和手感與其他潛水服沒什麼兩樣,但是使用的部分材料來自降解為分子的Patagonia二手潛水服。這件潛水服也將在使用壽命結束後被熔化,重新製成一件新的低碳潛水服。

Patagonia有一項持續多年的倡議,致力於消除衝浪者購買新潛水服產生的大量浪費,而這件潛水服正是該倡議的成果。儘管這間戶外服裝零售商保證為破損衣物提供終身維修服務,但終有一天,在文圖拉等待修補的大量舊潛水服將無法再縫合起來。有些衣服被回收利用,做成瑜珈墊或手提袋,但不可避免的是,最終它們都會被丟進垃圾堆填區。

究竟有多少廢棄的Patagonia潛水服,最終會轉化為售價500美元的再生潛水服,取決於該公司收集的廢棄潛水服數量。但這個策略會引入循環利用的過程,最終將產生終極永續的潛水服。

Patagonia材料開發人員沃納(Mackenzie Warner)說:「從本質上講,潛水服可以無限重複使用。」

價值20億美元的潛水服市場處於快時尚的對立面,這些廉價的一次性服裝在很大程度上造成了服裝業不斷增長的碳足跡。衝浪者往往不會成為時尚的奴隸,至少在潛水服方面是這樣,他們通常只在舊潛水服穿壞後才買一件昂貴的新潛水服。潛水服每年的銷售量約為700萬件,預計到2033年,全球市場規模將成長到35億美元。

𝗡𝗘𝗪 𝗪𝗢𝗥𝗟𝗗 𝗥𝗘𝗖𝗢𝗥𝗗 𝗜𝗡 𝗖𝗪𝗧 (𝗠𝗔𝗟𝗘)

On August 21st, at the 𝗖𝗠𝗔𝗦 𝟳𝘁𝗵 𝗙𝗿𝗲𝗲𝗱𝗶𝘃𝗶𝗻𝗴 𝗗𝗲𝗽𝘁𝗵 𝗪𝗼𝗿𝗹𝗱 𝗖𝗵𝗮𝗺𝗽𝗶𝗼𝗻𝘀𝗵𝗶𝗽 𝟮𝟬𝟮𝟯 in the Caribbean Sea, Roatan, Honduras, a long-awaited day finally arrived after 11 years. 𝗔𝗻𝗱𝗿𝗲𝘆 𝗠𝗮𝘁𝘃𝗲𝗲𝗻𝗸𝗼 (𝗜𝗡𝗧) made a bold monofin dive to a depth of 𝟭𝟯𝟰𝗺 (𝟰𝟰𝟬𝗳𝘁), establishing a new absolute World Record in CWT. This achievement is extraordinary because, for the past 11 years, 𝗔𝗹𝗲𝘅𝗲𝘆 𝗠𝗼𝗹𝗰𝗵𝗮𝗻𝗼𝘃 (𝗜𝗡𝗧) solely held the title of World Record Holder in CWT, with no challengers stepping forward.

Congratulations, Andrey, on your courageous and magnificent dive, as well as on achieving your first World Record!

𝗔𝗻𝗱𝗿𝗲𝘆’𝘀 𝗙𝗿𝗲𝗲𝗱𝗶𝘃𝗶𝗻𝗴 𝗖𝗮𝗿𝗲𝗲𝗿

Andrey, originally from Kamchatka, discovered his passion for spearfishing when he moved to the Black Sea coast. However, during the following winter season, he found himself drawn to freediving and began training in a pool. In 2010, he participated in his first freediving competition, where he won an overall bronze medal. This success led Andrey to shift his focus from spearfishing to freediving, both as a competitor and an instructor.

In 2014, Andrey achieved his first gold medal at the AIDA Team Freediving World Championship. During individual competitions, his proficiency lies in the CWT discipline. In 2019, he secured the title of Vice-Champion in CWT at the CMAS World Championship in Roatan and the AIDA World Championship in Villefranche-sur-Mer, reaching with a monofin impressive depths of 𝟭𝟭𝟱𝗺 (𝟯𝟳𝟳𝗳𝘁) and 𝟭𝟭𝟵𝗺 (𝟯𝟵𝟬𝗳𝘁), respectively.

During the 2021 World Championships, Andrey aimed to claim a medal in CWT by diving to a depth of 123m (404ft). Unfortunately, he encountered difficulties with the surface protocol and was subsequently disqualified.

𝗥𝗮𝗽𝗶𝗱 𝗣𝗿𝗼𝗴𝗿𝗲𝘀𝘀

Andrey, a strong and experienced athlete, is known for his sensitivity to nitrogen narcosis. This condition is typically more pronounced in dark and cold water. In preparation for the 2023 World Championship, Andrey trained in the challenging waters of the Black Sea, successfully reaching a depth of 𝟭𝟮𝟬𝗺 (𝟯𝟵𝟰𝗳𝘁). During his training sessions in the warm and well-lit Caribbean Sea, he further pushed his limits and achieved a depth of 𝟭𝟯𝟯𝗺 (𝟰𝟯𝟲𝗳𝘁).

On the first day of the CWT competition, Andrey made a conservative announcement for a dive to 𝟭𝟯𝟰𝗺 (𝟰𝟰𝟬𝗳𝘁) (the CMAS rules permit athletes to announce a depth 3m deeper than their personal best achieved in the last three months).

There were only a select few who could anticipate Andrey's announcement and foresee his attempt at a new world record. Nonetheless, he executed his dive flawlessly, securing his place in the history of freediving among the esteemed CWT World Record Holders. Congratulations, Andrey!

唔係愚人節,係真㗎!

#漁護快訊【4月至10月期間切勿進入深灣限制地區】

南丫島深灣嘅沙灘係本港唯一不時有綠海龜上岸產卵嘅地點,而預備產卵嘅綠海龜對人為干擾極為敏感,容易因為受驚而放棄產卵㗎~

為咗保護瀕危嘅綠海龜同佢哋嘅繁殖地,南丫島深灣沙灘同相連海灣已經被定為限制地區,每年4月1日到10月31日禁止市民同船隻進入。希望大家注意,一齊保育綠海龜!

「全球首個章魚養殖場」的提議引起科學家對動物福利的擔憂!😱西班牙跨國公司Nueva Pescanova計劃在加那利群島建立一個養殖場,每年養殖約一百萬隻章魚作為食材。
然而,科學家對提議中的冰水屠宰方法表示擔憂,認為這種方法是殘忍的。章魚從未被大規模養殖過,一些立法者、超市和動物福利組織已經反對這種做法。
您認為這是未來海鮮產業的可持續解決方案嗎?🤔🦑 #章魚養殖 #動物福利 #可持續海鮮

"World's first octopus farm proposal sparks alarm among scientists over animal welfare! 😱
A Spanish multinational company, Nueva Pescanova, is planning to build a farm that would raise about a million octopuses annually for food. However, scientists are concerned about the proposed icy water slaughtering method, which they consider cruel.
The octopuses have never been intensively farmed before, and some lawmakers, supermarkets, and animal welfare organizations are already opposing the practice.
Do you think this is a sustainable solution for the future of our seafood industry? 🤔🦑 "

SCUBA divers, listen up! 🌊🤿
New research from the European Journal of Applied Physiology suggests that the increased protein tau in your blood after diving may be related to distal arterial bubbles. 🧐
These bubbles can eventually evolve into lesions in the white matter, potentially causing impaired cognition. 😱
The study also found that repeated deep sea diving led to higher tau values, reinforcing the theory of distal arterial bubble formation. 💡
Stay safe and informed on the latest research in diving injuries.

試下派下禮物好似珊瑚普查咁😂

近年來許多研究所、實驗室都面臨了一個嚴重的問題,就是無法招收到有足夠潛水能力的學生。如果一位研究生在水下都無法照顧好自己,那要如何進行調查研究呢? - 國家地理雜誌中文網
