骨炭廢？作者: eliteman 時間: 2011-7-22 14:34
spent是定語，放在前面后面都可以，所以這個術語也可以寫作spent bone charcoal.
我猜，樓主是不是想把這個術語翻譯為廢骨炭？
樓主一定是在什么文獻里遇到了困惑，的確，從字面上來看，spent怎么會翻譯為“再生”呢？顯然，詞典里的翻譯是一種意譯。
我在加拿大食品檢驗局的網站上查到了他們對這種東西的一種定義：
Animal Bone Charcoal, Spent or Bone Charcoal, spent is produced by the charring and combustion of beef bones to be used in the filtration of raw sugar liqueur in the sugar refining industry. It is subsequently subjected to a repeated washing, drying, and heating process when exhausted.
It shall be labelled with guarantees for minimum percent calcium and minimum percent of phosphorus.
在美國骨炭生產企業(yè)--美國ACC公司的網站上也找到了一段有關他們生產的bone charcoal和spent bone charcoal的介紹：
Bone Charcoal:

Our standard packaging is in 50 lb. bags and in 2250 lb., metric ton bulk bags. Bone Charcoal is used for sugar decolorization, water filtration, soil remediation, soil augmentation and fertilization, air filtration, alcohol and mineral spirit filtration, as an absorbent of heavy metals and nuclear isotopes, as a digestive aid and as an animal feed additive.
ACC can also supply spent bone charcoal that has been used for decolorization in cane sugar processing. Spent bone charcoal is an excellent soil additive.
