I am a strong supporter of anything that can give Mother Nature some help, but this might just be my limit.
A Tokyo-based company offering everything from bookbinding services, child car seats and office products has a new (and certainly coolest) product, which turns used copier paper into toilet rolls, right in the office.
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 usually just be thrown away. At over 1,300 pounds (600kg). this is some serious hardware for very soft spot.
