捨てても捨てても - what does this phrase mean?

Question

I came across this sentence in my JLPT mock test book:

今の暮らしにはモノが溢れ、捨てても捨てても増え続ける。

I don't understand what kind of grammar and what is the meaning of the bold phrase. It looks like an expression.

Answer 1

It's a phrase to express "despite doing it over and over". You can use it with other verbs e.g. 食べても食べてもお腹がいっぱいにならない、拭いても拭いても落ちない etc

Answer 2

Unless it's an expression that I've never heard before, it just sounds like a straight-forward, emphatically figurative translation.

In my life right now, (I'm) overflowing/inundated with things; (such that) even if I throw them away [twice for emphasis], they continue increasing.
