利用舊T恤和樹​​木製造出布料

想像你穿在身上的T恤的原料很可能是用馬鈴薯皮、小麥秸稈、樹木、甚至是用過的舊T恤製成的。在芬蘭，一家初創公司開發了一項新的布料製造技術，可以將纖維轉化為紡織工業的紗線，讓時尚服飾不再成為環境的負擔。

總部設於芬蘭Jyväskylä的新創公司Spinnova，在2018年底打造了一個試驗工廠。這個試驗工廠內的專利機器可以將木漿或其他農業回收廢料研磨成細小的纖維，再進一步抽出紗線，然後紡成布料和製作衣服。這種生產方法將更優於棉花，棉花需要耗費大量的水資源才能生長，並且還需要使用大量的農藥。

Spinnova的執行長兼聯合創辦人Janne Poranen說道「我們的用水量極少！」，Janne Poranen是Fast Company 2019年實驗類世界變革思想獎的得獎者(2019 World Changing Ideas Award)。該新創公司計算出這種生產方式耗費的水資源遠要比棉花少99％以上，主要是因為它使用的樹木在生長時不需特別灌溉。該過程也不需使用有害化學物質。

與其他一些可以用樹木製成的材料（如嫘縈等）不同，這種生產方式不需要使用額外的化學品來分解堅韌的纖維。

「我們能夠生產出全天然的長纖維紗線」Poranen接著說：「這種獨一無二的材料還避免了像聚酯纖維這樣的人工合成纖維織物的問題，這些織物通常由石油製成，當微小的纖維從洗衣機的衣服上脫落並流入排水溝時就容易導致海洋中的汙染。

This tech can make fabric from old clothing, agricultural waste–and even trees

Your future T-shirts might be made from potato peels, wheat straw, trees, or even former T-shirts instead of virgin cotton. In Finland, a startup has developed new technology that can transform cellulosic fiber into fiber for the textile industry–without the environmental challenges of older materials.

Spinnova, based in Jyväskylä, Finland, finished building a pilot factory in late 2018. Inside, patented machines grind up wood pulp and agricultural waste into tiny fibers that can be spun into wool and then made into fabric for clothing. The process has advantages over cotton, which requires large amounts of water to grow–often in water-stressed regions–and also uses large amounts of pesticides.

“Our water usage is minimal,” says Janne Poranen, CEO and cofounder of Spinnova, the winner of Fast Company’s 2019 World Changing Ideas Award in the Experimental category. The startup has calculated that it uses more than 99% less water than cotton, largely because it’s using trees that don’t need irrigation as they grow. The process also doesn’t use harmful chemicals. Unlike some other materials that can be made from trees, such as viscose, it doesn’t use chemicals to break down tough fibers. The process is mechanical. “We’re able to produce continuous filament, which is basically all-natural,” says Poranen. “That is unique.” The material also avoids the problems of synthetic fabrics like polyester, which are typically made from fossil fuels and can contribute to plastic waste in the ocean when tiny fibers break off of clothing in washing machines and flow down drains into waterways.
