Mechanosyntesized products with voids inside that are lighter than water and thus when escaped from recycling may swim on the oceans like plastic long enough to be ingested by animals, will be quickly dissolved by gastric acid.

			== Misc ==

			Since magnesium is stronly electropositive (stronger than common transition element metals like iron)
			it wins out in thermite reactions (getting the oxygen) and conversley
			magnesium oxide is less prone to dissolution in molten transition metals (or metal rich silicate melts aka lavas / magmas).
