When balloons are deflated or punctured, they should be disposed of responsibly. Mylar and MicroFoil balloons can be recycled. Latex balloons can be discarded in a trash bin - Balloon Boutique uses only biodegradable latex materials. Please do not release balloons into the air. MicroFoil balloons in particular transmit electricity and therefore can cause fires (or worse) if released near power lines. NOTE: Helium gas should never be inhaled as it can cause serious and even deadly health complications including asphyxiation or air embolisms in the lungs.
