【EN】Expert’s talk: The big decryption of waste bottles being reproduced into eco-friendly clothing

天氣愈來愈熱,在環保意識抬頭的今日,自備水瓶裝飲用水、減少垃圾是最好的示範,但若一時忘記攜帶環保容器,臺灣人總是習慣在便利超商買罐寶特瓶裝的礦泉水或飲料解渴,喝完後,即丟進資源回收桶中,讓使用完的寶特瓶(PET瓶)進入新的回收循環中。

The weather is getting hotter and hotter. In the rising awareness of environmental protection today, it is a good demonstration to bring one’s own water bottle with them to reduce garbage. But if one temporarily forgets to carry their eco-friendly containers, Taiwanese are always used to buying mineral water in PET bottles or beverage to quench thirst from the convenience stores. After finishing, it is thrown into the recycling bin, letting the used PET bottle enter into a new recycling cycle.

根據行政院環保署統計,臺灣每年會回收10萬公噸廢寶特瓶容器、將近45億支寶特瓶,即便在回收率達95%的臺灣,這個數字也非常驚人。

According to the statistics of the Environmental Protection Administration of the Executive Yuan, Taiwan will recycle 100,000 tons of waste PET containers, nearly 4.5 billion PET bottles every year. Even in Taiwan, where the recycling rate is up to 95%, this figure is still very astonishing.

在全球都掀起減塑風潮的當下,「寶特瓶」仍是飲料產品的主要使用包材,而我們能做到的,除了減量以外,還必須更進一步理解「如何讓廢寶特瓶不再只是一次性使用的容器」而寶特瓶回收之後,究竟還可以做些什麼新的產品,讓資源能夠有效被利用呢?

In the global trend of plastics reduction, " PET bottles " are still the main packaging material for beverage products. The thing that we can do in addition to reducing the amount is to further understand, “how to make the waste bottle no longer only being a one-time used container.” And after the bottle is recycled, what new products can it make to let the resources be effectively utilized?

8支寶特瓶,就能變身成你身上的球衣!

It only takes 8 bottles to transform into the jersey on you!

根據遠東新世紀所提供的數據顯示,市場對於環保紗的需求逐年成長。在2018年,廢棄寶特瓶碎片使用量已經達到13萬噸。

廢棄寶特瓶從收集運至回收場開始就正式進入回收循環,先依據顏色與清潔狀況做初步分類後,再經由機器壓製成近400公斤的瓶磚,瓶磚會經過解包、洗滌、脫標籤、依照瓶身分色分類、粉碎、清洗、去除雜質、脫水,處理成乾淨的PET碎片

寶特瓶之所以需要這麼多重步驟,才能夠成為再利用的PET碎片,原因在於寶特瓶身顏色各異,再回收過程中又會歷經不同污染,唯有分類、清洗後才能進行後續作業。

According to the data provided by the Far Eastern New Century Corporation, the market demand for eco-friendly yarns are growing year by year. In 2018, the amount of discarded PET chips has reached 130,000 tons.

The waste bottle officially enters into a recycling cycle once they are collected and transported to the recycling site. It will first be classified according to its color and

cleaning condition, then be pressed into bottle bricks of nearly 400 kg by the machine. The bottle bricks will be unpacked, washed and the label will be taken off. It will be classified according to the color of the bottle, crushed, cleaned, remove the impurities, dehydrated, to become clean plastic chips.

The reason why it takes so many steps for the bottle to become recycled PET chips is because the bottles are different in color, and they will undergo different pollutions during the recycling process. Only by classification and cleaning can the subsequent operation be carried out.

以環保紗為例,環保紗是利用寶特瓶的原色製成,透明寶特瓶就會抽出白紗、綠色寶特瓶則會抽出綠紗,環保紗的製作需要高潔淨等級,紗線比頭髮還細,因此在抽絲過程中的不純物將會影響抽絲的效率以及環保紗的品質。

整體環保紗的製程相較於傳統的染製,雖然無法擁有更多色彩上的變化,但有助於節省水量與降低水污染,達到環保的目的。

Take the eco-friendly yarn for example, the eco-friendly yarn is made from the original color of the PET bottle. The transparent PET bottle will spin out white yarn whereas the green PET bottle will spin out green yarn.

The production of eco-friendly yarns requires a high level of cleanliness, yarns are thinner than the human hair, so the impurities in the spinning process will affect the efficiency of the spinning and the quality of the eco-friendly yarn.

Overall, although the process of making eco-friendly yarn is unable to have more color changes compared to traditional dyeing, it helps to save water, reduce water pollution to achieve environmental protection.

PET碎片最後經由加工廠,再以分解、重新聚合及高溫熔融,便可成為PET酯粒,這些重新回收再利用的酯粒,又稱之為回收聚酯(Recycled PET),不管是身上穿的衣服、還是再生環保瓶與再生包裝材的應用,都可以看見回收聚酯的蹤影。

PET chips finally become PET esters by decomposition, repolymerization and high temperature melting through the processing plant. These recycled and reused ester particles are also known as recycled PET. Whether it’s the clothes worn by the body or the regeneration eco-friendly bottle and the application of recycled packaging material, we can all see the trace of recycled PET.

為擺脫對石化原料的依賴,戮力發展回收聚酯材料,利用這些回收聚酯再製成的環保再生纖維,可以製成服飾用紗;每7到8支寶特瓶,就可製成一件運動T-shirt,整個製程可以減少40~85%的能源損耗、54.6%的碳排放。遠東新世紀在2018年製作的5億件環保衣便用掉了10萬噸的「環保紗」。

In order to get rid of the dependence on petrochemical raw materials, we endeavor in developing recycled polyester materials. By using the eco-friendly recycled fiber which is made out of recycled polyester materials, it can be made into apparel yarn; and every 7 to 8 bottles can be made into one sport T-shirt, the entire process can reduce energy consumption up to 40-85%, and carbon emission up to 54.6%. In 2018, the Far Eastern New Century Corporation has used 100,000 tons of "eco-friendly yarn" to produce 500 million pieces of eco-friendly clothing.

供應全球運動服飾回收寶特瓶再製環保紗的遠東新世紀,目前除供應NIKE、adidas等全球知名運動品牌製作運動衣,也同時包含美國NBA、美式足球隊的球衣。以2018年10個世足賽國家隊的每件足球衣中,都有寶特瓶再利用的蹤跡,遠東新董事長徐旭東更曾經透露,他們正在2020東京奧運部分運動項目的運動員衣服布料打樣中。

The global sportswear supplier, Far Eastern New Century Corporation, which recycles PET bottles and make them into eco-friendly yarns, currently produces sportswear for world-renowned sports brands such as NIKE and adidas, as well as jerseys from the US NBA and American football teams. In every football suit of the 10 World Football National Teams in 2018, there are traces of the reused PET bottles. Douglas Hsu, the new chairman of the Far East, has even revealed that they are working on the cloth proofing for athletes on part of some sport items held in the Tokyo Olympics in 2020.

從球衣到水果包裝盒,都可以看到回收寶特瓶的蹤跡

此外,我們也可以在再生環保瓶、再生包材應用上,看到回收聚酯的蹤跡,像是環保收納盒、塑膠棧板甚至是一般的水果包裝盒,都有可是寶特瓶回收後所製成的產品。遠東新世紀負責人表示,在利用廢棄寶特瓶碎片製作環保衣的過程中,遇到的最大困難在於前端廢寶特品的回收分類以及潔淨度不完整,這些不純物將會影響抽絲的品質與染色品質,也造成需要克服批次間品質穩定的困境。

Moreover, we can also see the traces of recycled polyester in the application of recycled eco-friendly bottles and recycled packaging materials, such as eco-friendly storage boxes, plastic pallets and even general fruit packaging boxes, could all be products made from recycled bottles. The person in charge of Far Eastern New Century Corporation has indicated that the biggest difficulty encountered in the process of making eco-friendly clothes is that the recycling classification as well as cleanliness in the front end of waste products are incomplete. These impurities will affect the quality of spinning and dyeing, which also causes the needs to overcome the dilemma of stability quality between batches.

一個寶特瓶有90%以上可回收再製成聚酯纖維、一公斤的寶特瓶,相當於0.8公斤的原油,當一般民眾都能夠記得,在享用完瓶裝飲料之後,稍微清洗一下寶特瓶、輕輕壓扁後再蓋上瓶蓋,順勢丟入回收桶中,讓這個與我們「短暫相遇」的寶特瓶,能有更長期、再生的利用價值,就是對地球環境多一分保護與珍惜。

More than 90% of a PET bottle can be recycled into polyester fiber and one kilogram of PET bottle equivalents to 0.8 kilograms of crude oil. When the general public can remember, after enjoying the bottled beverage, by simply washing it, lightly squashing it, putting the cap on, then throw it into the recycling bin at one's convenience, allowing this "short encountered" bottle to have a longer-term, a regenerative use of value, this will be a way of showing protection and cherish to the global environment.
