想問 無污染英文係 NON-POLLUTION 定 NON-POLLUTED? TKS!?

Pollution free, non-polluting or simply green.

Examples:
1. XXX is a pollution free technology at low cost for portable computer battery.
2. It uses non-polluting manufacturing processes for the entire life cycle.
3. It is the greenest high tech product you can find in the market.

NO POLLUTION

無污染＝No Contamination

There is no pollutants in the air.

Non-pollution/non-polluted 係chinglish(中式英文)，並冇呢個字。
無污染嘅英文係：taintless/pollution-free/contamination free

另外，pollution 同 polluted 嘅分別如下：
Pollution 係名詞
E.g. Pollution is serious in this city.
Polluted 係形容詞
E.g. The air is polluted.

希望幫到你(^o^)

NO-POLLUTION

pristine

Un-polluted 沒有被污染的...
Non-polluting 不會造成污染的...

pollution這名詞是指已成破壞的污染，所以不會以加non作反義詞。因為non作反義是指"不作某行動的主動性"，一般意思是non-action：(non-disclosure, non-irritate, non-conform, non-transferrable, non-stop)或表達一些"不是"的東西：(non-metal, non-conductor)。
假如是指物品或工序本身是"無污染，因此只會寫Without causing pollution或pollution-free。
