Crunch Gear

Tokyo-based Nakabayashi offers everything from bookbinding services, child car seats and office products. But the newest (and certainly coolest) product of the 2,000-man company is an in-office machine , which turns used copier paper into toilet rolls, right there in the office. Brillant. The toilet paper machine is able to produce two rolls per hour from around 1,800 sheets (or 7.2kg) of used A4-sized paper, which would have usually been just thrown away. At 600kg, it seems to be a dangerously massive piece of hardware. Distribution in Japan begin in August and Nakabayashi wants to sell 60 units in the first year. Good luck with that, as each machine comes with a price tag of $95,000. Unfortunately, there is no information on operating costs yet, but I can’t imagine these being in proportion.
