Stay away from bamboo coffee cups, German consumer group warnsPosted on September 4, 2019 by DrRossH in Plastic Waste News
Stiftung Warentest also slammed the manufacturers for not properly warning about the dangers of placing the bamboo cups in the microwave. When heated to high temperatures, the cup’s material will begin to decompose: as the cup’s surface is destroyed, it will release even more melamine and formaldehyde. One cup’s packaging simply stated that it should be kept out of the microwave to prolong its life.
Many of the cups also suggested that they were “biodegradable” or “recyclable”. Stiftung Warentest maintains that this is a barefaced lie. Of course, natural bamboo fibres will biodegrade over time, but the cups will not rot, even if you give them years. Neither can they be recycled via standard methods – the only option is to burn them.
