Recycle symbol
 

Hi!
Do you know the recycling symbol composed of a triangle made of arrows?
The Japanese version has written in it the word プラ... do you know what does it mean? I've looked for it in some dictionaries, but I haven't find it...

It was easier than I thought :)
Thank you!

I might add this so there would be no misunderstanding about プラ.

We actually never shorten プラスチック to プラ in either spoken or written Japanese. We always use the former. In these recycling symbols, however, プラ is used probably because プラスチック is too long to blend into a simple design.

If you use プラ in any kind of conversation, we will have absolutely no idea of what you are referring to.

But for プラスチックモデル　you can shorten it to プラモ　right?
