The stone paper is made of plastic and inorganic mineral powder, therefore the recycling way is the second type of recycling. What’s more, recycled stone paper can be broken into grain which can be added for producing plastic products. The environmental labeling is: Cradle-to-cradle design (also referred to as Cradle to Cradle, C2C, cradle 2 cradle, or regenerative design) is a biomimetic approach to the design of products and systems that models human industry on nature's processes viewing materials as nutrients circulating in healthy, safe metabolisms. The term itself is a play on the popular corporate phrase "Cradle to Grave," implying that the C2C model is sustainable and considerate of life and future generations (i.e. from the birth, or "cradle," of one generation to the next versus from birth to death, or "grave," within the same generation.) (1) Recycling to wood pulp paper recycling plant, Put it into dissolving pulp pool then fish up as disposal.

(2) Light degradation can still be conducted for stone paper without crimson solution agent during the production. And the reasons are as follows: on the one hand, micron-sized stone powder easily absords heat and gets temperature raised under the sunshine, which damages adhesives (plastic cement ) by generating steam and carbon dioxide. On the other hand, the ultraviolet light breaks the molecular bonds and then leads to the structure fracture of adhesives(plastic cement ). Our company put the 200μm stone paper under the sun for 6 months, and the final result was that the stone paper was broken naturally like a eggshell. Besides, we arranged solar simulator ultraviolet irradiation tests with 200μm stone paper, and the test result was also similar to actual sun exposure experiment.
