Bamboo mugs are so bad for people and the environment

As the garbage cans in the streets overflowed, many citizens decided to switch to the thermos and bamboo cups. The latter are ideal for traveling. They are light, sturdy, can be filled anywhere and are good for the environment. But as Stiftung Warentest discovered, the colorful bamboo mugs are by no means an eco-friendly alternative because there are too many pollutants to contain, incorrectly stated they are and also plastici.e. plastic, in the material.

This is really in the cups

The mugs are advertised as a purely natural product, which is made from environmentally friendly materials and can also be completely degraded. In reality this is not the case: Bamboo coffee mugs are made not only of the fine powder of ground bamboo, but also of an adhesive and melamine resin. This resin is a plastic composed of formaldehyde and melamine. Under the right manufacturing conditions and certain usage behaviors, melamine is not harmful and is also used for children’s tableware. Up to a temperature of 70 ° C the substance does not release significant quantities of pollutants.

Possibly harmful to health

At temperatures above 70 ° C melamine is suspected Diseases of the bladder and kidney systems to cause. can of formaldehyde irritation on the skin, respiratory tract and eyes and increases the risk of inhalation Cancer in the nasopharynx. This is one of the reasons why it is not recommended to put the bamboo cup in the microwave.

This is how Stiftung Warentest looked at the cups

To test the amount of pollutants released by the bamboo cups, the cups were filled with 3% acetic acid and kept warm at 70 ° C for two hours. The vinegar should simulate a slightly acidic liquid such as coffee. The cups were filled a total of seven times. On the third and seventh fillings, the levels of melamine and formaldehyde in the liquid were measured.

The result

Stiftung Warentest found very high melamine content in four out of twelve cups after the third filling and in three more cups after the seventh. Formaldehyde was also included high quantities found. With each further use of the cups, more formaldehyde accumulated in the drink.

Mugs harmful to the environment?

Since bamboo cups contain plastic, they are far from biodegradable. Stiftung Warentest criticizes the insufficient declaration of the glasses, after all the recycling symbol (the triangle of three arrows) has no place on the glasses. The components of the cups can no longer be separated during recycling. Energy recycling follows: incineration, which makes no sense for environmentally conscious buyers.

Which cups can I still use?

For bamboo cups, look at the structure of the material. Unlike bamboo cups with plastic, this can be seen in pure bamboo products. Alternatively, you can also upgrade to a thermo mug. Metal lasts for many years!
