科學家們找到了利用塑料垃圾發(fā)電的方法
Scientists may have discovered an environmentally friendly way to turn plastic waste into renewable energy.
科學家們可能已經(jīng)發(fā)現(xiàn)了一種將塑料垃圾轉(zhuǎn)化為可再生能源的環(huán)保方法。
In a series of lab experiments, researchers in Singapore successfully converted plastic into formic acid — a chemical that can be used to generate electricity in power plants and electric cars.
在一系列的實驗室實驗中,新加坡的研究人員成功地將塑料轉(zhuǎn)化成甲酸——一種可用于發(fā)電廠和電動車發(fā)電的化學物質(zhì)。
“We are able to turn plastics, which are of course polluting the oceans, into useful chemicals,” Soo Han Sen, head of the two-year research project at Nanyang Technological University, told AFP.
南洋理工大學這項為期兩年的研究項目的負責人Soo Han Sen對法新社表示:“我們能夠?qū)⑽廴竞Q蟮乃芰限D(zhuǎn)化為有用的化學物質(zhì)。”
“We’re hoping to turn this into a fully renewable process that’s carbon neutral.”
“我們希望把它變成一個完全可再生的過程,是碳中性的。”
To develop the process, the research team created a catalyst from vanadium — a cheap metal often used in steel alloys for vehicles that doesn’t damage the environment.
為了開發(fā)這一工藝,研究小組用釩制造了一種催化劑。釩是一種廉價的金屬,通常用于制造汽車合金,不會破壞環(huán)境。
The catalyst is then dissolved in a solution containing the plastic and exposed to artificial sunlight, breaking down the carbon-carbon bonds inside the plastic and turning the once non-biodegradable material into formic acid.
然后,催化劑被溶解在含有塑料的溶液中,暴露在人工陽光下,分解塑料內(nèi)部的碳-碳鍵,把曾經(jīng)不可降解的材料變成甲酸。
The findings were published in Advanced Science.
研究結(jié)果發(fā)表在《先進科學》雜志上。
“This new chemical treatment is the first reported process that can completely break down a non-biodegradable plastic such as polyethylene using visible light and a catalyst that does not contain heavy metals,” Sen said in a press release.
森在一份新聞稿中說:“這種新的化學處理方法,是首次報道的利用可見光和不含重金屬的催化劑,完全降解聚乙烯等不可生物降解塑料的方法。”
Sen and his team have only been able to convert tiny amounts of plastic into formic acid so far, adding that there will be challenges to replicating the process on a bigger scale.
森和他的團隊到目前為止只能將少量的塑料轉(zhuǎn)化成甲酸,并補充說,在更大的范圍內(nèi)復制這一過程將會面臨挑戰(zhàn)。
