Is the attempt to make environmentally friendly roadways doomed to wind up in the toilet? Actually, it may be the other way around. To earn a green certification, the Meador Kansas Ellis Trail in Bellingham, Washington, included 400 recycled commodes in the concrete.
建造環保道路一定要拆除沿途的廁所嗎？事實上，我們可以采取正好相反的措施。為了拿到綠色證明，美國華盛頓州貝靈翰姆的米德-堪薩斯-艾利斯小道在水泥路上安裝了400個可再生廁所。
Greenroads is a new rating system, developed at the University of Washington, which judges the sustainability of roads and road construction projects. Under the system, projects must incorporate 11 specific features, such as dealing with waste from the construction process, as well as some optional practices, which in the case of the Meador Kansas Ellis Trail included recycling.
在華盛頓大學創立的“綠色道路”是一項新的評級系統。它能評估道路和道路建設工程的可持續性。這項系統對工程的評估有11條具體標準，如處理建設過程中產生的廢物的能力和其他的一些措施。米德-堪薩斯-艾利斯小道采取的就是循環法。
The toilet interment helped the project win the first official Greenroads nod, earning a silver certification. About 30 percent of the pavement consists of recycled concrete and, yes, crushed-up toilets, nicknamed “poticrete.”
廁所葬禮幫助這個項目贏得了綠色道路的第一次官方肯定，并得到了銀牌認證。米德-堪薩斯-艾利斯小道大概有三分之一的部
分由可再生混凝土和粉碎的廁所（俗稱“poticrete”）組成。
But this project's sustainability relies on more than old thrones. The Trail's porous concrete prevents excessive run-off; it's illuminated with low-energy lighting; and its mere presence encourages bicycle and foot traffic. These green features mean that sustainable roadways can be more than a pipe dream.
但是這個項目的可持續性不僅源于廁所本身。道路的多孔混凝土可以防止水的過度流失；節能燈可以給道路照明；窄小的面積可以鼓勵人們騎自行車或步行。這些綠色特征表明可持續道路不會只是個白日夢。
