My questions are more along the lines of: What has happened to the feedstock used that has been produced into a product whilst fine tuning production? Week on week , month on month the plant is running and trying to achieve the optimal product. What happens to the reject product? There is obviously buckets of it.Can it not be reprocessed? Whilst not re-run at 100% you would think they could feed in 5 or 10% with the virgin mix and not compromise the end product. Do they just throw it away? Maybe they sold it to SimsMetal as scrap but on the market it would surely be worth more than they are saying they recieved.
