How can one write "Please Recycle" in the context of an office paper room? I have tried: 请回收利用 but my friend says this is only for recycling batteries.
I think 請回收利用/请回收利用 can apply to lots of stuff as well, for example, plastic bottles, tins, cans, glass and so on.
If you really want to be specific about recycling paper, you can try
請回收廢紙/请回收废纸 = Please recycle used/unwanted paper
請回收紙張/请回收纸张 = Please recycle paper
Note that the above Chinese examples are written in Traditional/Simplified.
请回收利用 usually means waste recovery. You can try to write:
In the streets and lanes of China, recyclers often collect waste products, which are usually paper and some of them are electrical appliances，there are also some daily necessities.
But there（废品）is no doubt that it is absolutely useless to people.
- 請回收 / 請回收再造 - Please recycle
- 請回收廢紙 / 請回收紙張 - Please recycle waste paper / Please recycle paper
(in Traditional Chinese)
There are Three R's.
- Reduce （減少使用）
- Reuse （廢物重用 / 重複利用）
- Recycle （循環再造）
And an additional R sometimes.
- Replace （替代使用）
