生物濾化技術
With more than 1.4 billion cars in the world today, the effects on the environment are significant.
全球現今有超過14億台車，這對環境有著很大的影響。
effect(n.)效果;影響significant(adj.)重要的;顯著的
Electric vehicles (EVs) are a possible solution, but producing the batteries requires metals like lithium, cobalt and nickel, which are hard to come by.
電動車（EVs）的開發或許是解決之道，但製造電池需要鋰、鈷與鎳等這類不易取得的金屬。
solution(n.)解決方案produce(v.)製造;生產be hard to come by=難以取得
To compete with traditional vehicles, researchers are looking for ways to obtain these metals while keeping costs low.
為了與傳統汽車競爭，研究人員設法獲取這些金屬，同時維持低成本。
compete(v.)競爭obtain(v.)獲取;得到
EV manufacturers have mostly been focusing on mining the metals.
電動車製造商一向只專注於開採金屬，
focus on sth.=專注於某事mine(n.)礦井(v.)開採
Meanwhile, waste electronics containing these metals are piling up in landfills, and only 5% of lithium-ion batteries are being recycled in places like the EU.
含有這些金屬的電子廢棄物在垃圾掩埋場推積如山，以歐盟國家為例，只有5%的鋰電池被廠商回收。
contain(v.)含有;包含pile up=堆積起來
Furthermore, recycling batteries is expensive and produces lots of carbon emissions and other toxic waste.
而且回收電池的成本很高，過程中還會排出大量的碳與有毒廢棄物。
emission(n.)(液體;氣體的)排放emit(v.)排放waste(n.)廢棄物
The Bioleaching Research Group at Coventry University is working on a new way to recycle batteries.
考文垂大學生生物濾化技術研究團隊致力研究回收電池的新方法。
leach(v.)漂洗;過濾
The process, called “bioleaching,” uses bacteria to recover materials from electronic waste without toxic chemicals and emissions.
生物濾化技術利用細菌將電子零件中的金屬提取出來，過程中不會釋放有毒化學物質與氣體。
recover(v.)恢復;復原;失而復得;重新獲得
Unlike the current method, bioleaching can recycle all of the metals in EV batteries indefinitely.
不同於現行技術，生物濾化技術可無限重複提取電動車電池中的金屬。
indefinitely(adv.)無限地
Research has shown that bioleaching is the better option, but industries cannot always afford to make big changes.
儘管研究表明生物濾化技術是更好的選擇，但各大產業並非總能負擔得起創新的成本，
afford to RV=負擔得起…
Ultimately, it’s up to the governments to make new policies and invest in cleaner technologies.
最終只能交由政府制訂新政策與投資環保技術。
be up to sb.=由某人來決定policy(n.)政策invest(v.)投資;投入
