"In contrast," Wu states, "the fluorosilicate that we use is not explosive, so it is very safe. Moreover, the second great thing about it is that it is reclaimed from waste." Every year mainland China's phosphate fertilizer industry produces about 3 million metric tons of wastewater. Only about 20 tons are recycled; the rest is dumped into rivers.
「我們採用的氟化物除了在化學過程中不具燃燒性，十分安全外，第二個特色是廢物利用，」吳以舜表示，中國大陸每年從磷肥工業產生的廢水約 300 萬噸，只有 20 噸回收，其餘都排入河川造成污染。
