For example, it costs FPG NT $ 6,000 per ton to have mercury waste buried in landfills in Taiwan, but it was only charged NT $ 3,000 per ton to have it disposed of in Cambodia. If both options were legal, why wouldn't companies choose the cheaper one?
以台塑為例，這批汞汙泥在台灣掩埋，一噸要花六千元，到柬埔寨只要三千元，若是兩個方法都合法，業者為何不選擇便宜的做法？
