Can I use recycled aluminum foils?

Recycling aluminum foils is a sustainable practice, but reusing them is not recommended for food contact due to potential contamination and hygiene concerns. While recycling aluminum is energy-efficient and reduces waste, it's important to ensure that used foils are properly cleaned and processed for recycling. For food safety, it's best to use new, clean aluminum foil each time to avoid the risk of spreading bacteria or other contaminants.
