What is it: A toilet paper machine that turns office paper into toilet tissue
Invented: 2010

Like many other Japanese inventions, the White Goat Paper Recycler is a leader in green energy. This Recycler converts discarded office papers into toilet paper. The machine costs about $100,000, which is the same as a Tesla Model S for 2016.

Recycler turns used sheets of cellulose to toilet paper, saving up to sixty cedars per year. The office paper is placed on one side, and the final product appears from the opposite side. The eco-friendly benefits make it worth the time.
