I was saying our production processes help low-carbon footprint. Here is one part of it :
A. "For the machining of our parts, after numerous tests in half a year, grinding, which produces lots of powder pollutions, has been replaced by a new milling process .
B. "For the machining of our parts, after numerous tests in half a year, grinding that produces lots of powder pollutions, has been replaced by a new milling process .
I want to mean: after lots of tests, the milling process is developed and have replaced grinding. For the bold part I first used A, the non-restrictive attribute clase. I am wondering if B is better?
Could you please help? Thank you.
