The laws of physics make this declaration impossible, e.g. Entropy; burning; oxidation. The alternative is replenishment (e.g. growth) and minimisation. Prohibitive costs create practical impossibilities.
“No material should be processed in ways where recovery or replenishment of its original substance is practically impossible; this type of destructive processing must be prevented in all its forms.”
Not impossible, just challenging. We live in a world with finite resources. We must either find solutions how to return materials to their original natural state or we must use other materials to begin with.
