Lanvin for H&M : The waste collection

Hi. Did you know what H&M do with the waste from Lanvin x H&M collection? They recycled!
I love the idea altough that I don't like some pieces from this (new?) collection. It'll be few pieces but sincerely I'm not too interested, but I think that it's a really good idea. And you? What you think about this?
