RHEOMOD commented on Coffee Soul Cup

Dear Victor: Thank you for your question. A cup made o cardboard might decompose as you stated, but a regular cup used for coffee will take much longer due to the liner of polymer/wax that is in the interior of the cup. This liner makes it "resistent" to the hot beverage and thus the self-decay is never activated. In the cup concept that we propose the cardboard is replaced by a biodegradable polymer, one that will be food to bacteria. However, degradation or self decay of the cup will only be activated when you leave the cup in the presence of bacteria. Thus if you are drinking your hot beverage, finish and wash the cup, the cup will not degrade significantly. If you dump the cup in the trash and this becomes in contact with bacteria, the microorgranisms will begin feeding on the cup and it will eventually disappear. Here is a link to the polymer producer: https://danimerscientific.com/pha-the-future-of-biopolymers/pha-impact/ if you want more info.

RHEOMOD commented on Coffee Soul Cup

Dear Rafeed: Thank you for your comment. As an answer we can mention that the amount of spent coffee grounds that will be used in the cups will amount to only a fraction of the current waste that is generated during coffee brewing around the world. Thus we will provide a solution to a current problem. Coffee production will not need to be increased.
