The European Union (EU) by Rapid Alert System for Food and Feed (RASFF), 37 cases since 2019 have been related to the release of excessive formaldehyde and melamine from bamboo-related food contact products. Melamine can cause disorders of the bladder and renal system, and formaldehyde can even cause cancer.
Products such as bamboo melamine coffee cups and tableware are often promoted as environmentally friendly, biodegradable or made from renewable raw materials. But if it is added to a melamine resin, it becomes a plastic product as a whole and is not biodegradable despite of that bamboo fiber itself is biodegradable.
TUV Rheinland recommends that consumers avoid using products such as bamboo melamine coffee cups and tableware for high-temperature beverages or foods.
