My understanding is that the temperature used to melt aluminum, steel, and other metals for recycling is so high that food waste burns off quickly and doesn't pose any contamination problems. At worst you might have some slag to skim off the top. Paper is the main thing that frequently has contamination problems, because it can't be treated with high heat during the recycling problem lest you just end up paper. Even plastic is heated pretty decently during the recycling process. |
