Meaning of ゴミはわけて捨てなくてはいけない


> 男: えっ、でもこれ全部ゴミなんですけれど・・・。  
>  女: ちょっと見せてね。あら・・・だめだめ、これじゃ。いい？ **ゴミはわけて捨てなくてはいけない** んです。  
>  男: わけて捨てるんですか・・・。

This is from the book 聴解が弱いあなたへ. I didn't pay much attention to it, but I have
a question about the sentence in bold.

I think this sentence means:

> You have to sort your trash before disposing.

If I translate it literally, I would get:

> As for trash, sort it and if you don't dispose it, that's bad.  
>  or: As for trash, sort it and you have to dispose it.

(I translated いけない as "bad")

I'm specifically confused about 捨てなくてはいけない, which means "must throw away".

Question: _Does 捨てる being in negative form also make わける also in negative
form? Does なく affect both of those verbs? In this case, does it literally
mean?:_

> As for trash, if you don't sort it and dispose it away, that's bad.  
>  or: As for trash, you have to sort it and dispose it away.




It's

> ｛分けて捨て(る)｝ + なくてはいけない  
>  must + {throw away separately}

rather than

> 分けて + ｛捨てなくてはいけない｝  
>  sort + {you must throw away}

わけて can mean "separately", eg 「それとこれとは **わけて** 考えなければならない」(≈別々に考えなければならない)

Similar examples:

> ｛離れて暮らさ｝なければならない  
>  must + {live separately}  
>  ｛急いで家に帰ら｝ないといけない  
>  must + {hurry home}  
>  ｛歩いて学校に行か｝なくてはいけない  
>  must + {walk to school}
