What it is: A toilet paper-to-office paper machine
Year of invention: 2010; average cost: $100,000*
Like many other Japanese inventions, the White Goat Paper Recycler is at the forefront of green energy. Toilet paper is created from used office paper by this recycler. At roughly $100,000, the machine is not inexpensive—it costs about the same as a 2016 Tesla Model S.

By converting used cellulose sheets into usable toilet paper, the recycler helps preserve up to sixty cedar trees annually. Simply insert the office paper on one side, then watch for the completed product to come out of the other. Although it takes some time, the advantages for the environment are worthwhile.
