| Photo-degradable Paperocks unique “rock” paper is 100% Photo-degradable, since its principal component is calcium carbonate mixed together with a small portion of NON-toxic plastic and resin. When left out in the sunlight & heat, it will naturally crack and decompose back into powder form over an 8-12 month period. In nature, egg shells are also composed primarily of calcium carbonate and the decomposition traits are virtually identical. |
