The good work should go on
I certainly know a good deal more about this than I did 15 minutes ago before I started reading this article! There have been a number of article improvements, and the article is going in a good direction.
1) Since I've held pelletized plastics in my hand, I know they exist. Should the article include something specific to them?
2) Some terms could use explanation: for example, "daily pay burn", "after-burn", and "fitted conditioners".
3) Most importantly, it's not clear why things such as iron are pelletized. Animal feed...that's pretty easy to figure out...it needs to be a comfortable size for animals to eat. But why are other pellets created? Phrases such as "appropriate for use in a blast furnace"...the editors know what "appropriate" is, so it would be good to include this information in the article?
