No trees are wasted in producing Repap, though about 20% of the mass is made up of polyethylene resins. The rest is taken from stone quarries and recovered from waste materials in the building industry. Limestone, for example, is made entirely of various calcium carbonates and is sometimes used in construction.
Unlike paper, Repap notebooks are waterproof and can be erased and reused. They are also biodegradable and according to Ogami a notebook will decay in 14 to 18 months if left out in the sun.
Hmm. Doesn't that make you wonder of Repap was originally developed by a very patient Mission: Impossible agent?
The notebooks are readily available online, and they retail for $13 to $20 each, depending on the size. I bought a couple, and so far they have lived up to the description. The pages have a much smoother texture than regular paper. They are water-resistant and more difficult to tear.
But now that I have them I'm not sure what I will do with them other than show them off. I don't exactly need a more durable, water-proof notebook.
