When Hong Kong intercepted yet another huge shipment of illegal African ivory in early October, it added to a growing headache for authorities: What exactly do you do with one of the world's biggest stockpiles of elephant tusks?
Government warehouses in the former British colony are holding more than 30 metric tons of ivory seized since 2008, as customs agents intercept a surging amount of endangered animal products being smuggled to mainland China to meet demand from the country's newly wealthy.
The latest shipment, 189 tusks worth $1.5 million hidden in soybean sacks in a shipping container, was one of four major busts this year.
Ivory is known as "white gold" because of the rich prices it commands on the black market. Hong Kong has put values of between $1,000 and $2,000 a kilogram on ivory it seized this year. A 2011 report by the International Fund for Animal Welfare said buyers in China were paying up to $2,400 a kilogram.
