You can recycle clean aluminum foil.
Check with your local provider for specifics but in Austin, Texas clean aluminum foil can be balled up 2 inches or larger and go in the curbside recycling carts. You can also recycle aluminum baking pans.
Word of caution: Sometimes people think they’re hosting a zero waste event by having breakfast tacos. If your tacos are going to have cheese and bean, etc. all over the aluminum foil, that aluminum cannot be recycled at the event. Someone’s going to need to clean all that food off that aluminum foil before it can be dried and balled up to recycle.
Tacos are possible as a zero waste food option at an event, but keep in mind there might be some cleaning that needs to happen. Trays of taco components to assemble would be a better choice than prewrapped tacos. The event hosts can easily rinse off the metal trays after the event and recycle them. Recycling should not have food contaminant on it. That food residue contaminates the recycling stream, causing either decreased revenue from a dirtier product, and/or causing fines to the city from the recycler.
