Human Vending Machines!!

Human tea leaves?

The world is in danger. We all know that everyone has to do their part in order to ensure the survival of the human race. Countries and companies are creating new and innovative ways to protect our environment and make business more Eco-friendly. That being said, Japan is no exception.  In fact, Japan has now gone one step above everyone else in terms of recycling. Japan has become the first place to recycle humans to create vending machines.
Just kidding...or am I?
The picture above is from a vending machine in Japan that claims "they utilized recycled tea leaves which are human and environmentally friendly".  I am a bit confused. So is this machine made from human remains or is it made from tea leaves that were consumed my humans who are now deceased and being used to build these machines? Either way it is a scary thought.
Of course this is probably just another Japanglish error where someone in the advertising department was too lazy to translate some text and used an online translator instead. But I'd like to think the former because that would be awesome.
Only in Japan...
