Disposable Packaging And Table Mat Made Of Stone Paper Waterproof Moistureproof Oil Resistant Mud Proof Wood Pulp Free
Stone paper is made using calcium carbonate, a compound found in rocks, and bio-resin. The two materials are combined to form a non-toxic and recyclable material that has the texture and look of regular paper. The production process involves crushing the calcium carbonate into powder, melting the resin, combining the two ingredients together and then cooling them. Once cooled, the mixture is extruded through rollers which form sheets of stone paper. The sheets are then cut into desired sizes for use as stationery items such as notebooks or cards.

Stone Paper has a direct influence on the environment. Replacing regular paper by Stone Paper results in a significant decrease in environmental impact. CO2 exhaustion is dramatically lower and above all, the production process is very clean. No water is used, no bleach or chemical solutions and of course not a single tree is felled.
We compared the sustainability of Stone Paper vs regular paper
Cradle-to-gate: we took in account all CO₂-exhaustion as a result of: attaining, processing and transporting of raw materials; producing the paper; transport from the factory, and intermediate storage, to the client. Stone Paper produces 474 kg CO2 per ton compared to 1.431 kg CO2 per ton for pulp paper.
Raw materials and their impact on the environment
Stone Paper: Calciumcarbonate (80%), originating from waste material from stone quarries, completely recyclable, recycle-percentage 58%. Recycled HDPE (20%), completely recyclable, recycle-percentage 27% Pulp paper: wood pulp is produced from wood, for this 18 trees are required, wood pulp can be recycled up to 8 times max, recycle-percentage 69%, 92% of forests for pulp-production has a certificate for sustainable forestation.
Comparison: Stone Paper is produced entirely from recycled waste material and has a minimal impact on the environment, all the while 18 trees are required to be chopped down to produce 1.000 kg of pulp paper, which can only be replaced after slowly growing them back. Pulp paper has a higher recycling percentage than Stone Paper, but can only be recycled up to 8 times.
Water consumption during production
Stone Paper: the production process is free from water consumption: 0 liter water per 1.000 kg Pulp paper: during production 35.000 liter of water is used, of this 2.770 liter per 1.000 kg pulp paper is consumed and the rest is re-used later.
Comparison: By choosing for 1.000 kg of Stone Paper over 1.000 kg of pulp paper the consumption of 2.770 liter of water is prevented. This is equal to the drink water consumption (coffee, tea, glass of water, etc.) of an average person over the course of more than 50 months.
Waste that is not re-used during the production process
Stone Paper: no waste during the production process: 0 kg waste per 1.000 kg Pulp paper: almost no waste during the production process: 15 kg waste per 1.000 kg.
Comparison: Both types of paper have a very low waste percentage. Stone Paper scores slightly better on this area than pulp paper.
Recycle Ways of Stone Paper
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.
