Stonepaper – material & recycling
1. How is stone paper made?
The stone paper production process is an invention from Taiwan. Over the past 20 years, a technology was developed to produce paper with less impact on the World than traditional pulp paper. The stone paper now has a Cradle to Cradle silver certificate and the technology is spreading rapidly around the World. We would like to share the basic process of making stone paper.
The stones used for the production of stone paper are calcium carbonate, and come from mines. The color of the stones, is the color that the paper will take on. Therefore, mainly white/yellow-white stones are used.
These stones are ground to dust, then mixed with a little (partly recycled) HDPE. This component functions as ‘glue’ for the stone minerals. Due to this combination of resources, recycling of the material becomes infinite. The Calcium Carbonate minerals don’t lose their form, as opposed to pulp paper fibers that do break after recycling and end up as waste in the end.
The heated mix of HDPE and dust pellets, become a texture comparable to a balloon. This mixture can be stretched out very high, and thus as thin as wished for. At the same time the material cools down and can then be rolled up into paper rolls.
Unique characteristics
Stone Paper is a new generation of paper and an excellent alternative to traditional paper. it’s tree-free paper that consists almost entirely out of minerals.
1. 100% waterproof
Liquids such as water and oil do not affect Stone Paper.
No wood fibers
The swelling of food fibers destroys woodpulp-paper when it comes in contact with liquid. Result: deformation of the print surface and a destroyed product.
Stone Paper is 100% waterproof and liquids have no effect on the material. If it gets wet, you can simply dry it.
2. 100% Tree free. Stone Paper saves trees.
1 ton Stone Paper instead of woodpulp paper means oxygen for 40 people a year.
Completely produced from waste product.
18 trees need to be cut down for 1 ton woodpulp paper.
Stone Paper consists entirely out of waste and recycled material and therefore has a much lower impact on the environment. For a ton of woodpulp paper, 18 trees need to be cut down which are then replaced with fast growing trees that destroy the bio-diversity. Pulp paper can be recycled 7 times but each process has the same destructive effect on the environment.
3. Save 2270 liter water
1 ton Stone Paper instead of woodpulp paper means 142 days of showering.
Stone Paper: Zero water usage
35.000 liters of water is necessary for the production of woodpulp paper.
During the production of 1 ton of woodpulp paper 2.770 liter out of 35.000 is lost. So using Stone Paper saves 2.770 liter of water, the equivalent of 50 glasses of water per person per month.
4. Reduce 949kg CO2
During the production of 1 ton of Stone Paper instead of woodpulp, you save the amount of CO2 that would be expended on a journey of 4.520 km by car.
Stone Paper 482 kg CO2, Pulp papier 1.431 kg CO2.
The CO2 emission from production to end-user: the CO2 emission caused by the production process, transport and raw materials. The emission is 67% lower than woodpulp paper. Choosing for Stone Paper is comparable to preventing the CO2 emission of a trip from Amsterdam to Jerusalem by car.
5. Save 85% energy
1 ton Stone Paper instead of woodpulp paper means saving the equivalent energy usage of an average household over 1.5 years.
Stone Paper needs 3,1 Gigajoules, woodpulp paper 20,4 Gigajoules.
For 1 ton Stone Paper you only need 3,1 Gigajoule energy due the very effecient production process. So the required energy is only 15% of that of woodpulp paper.
6. No chemicals
These chemicals are necessary to bleach woodpulp fibers..
Stone Paper uses no harmful chemicals.
During the production of woodpulp paper, various harmful chemicals are used to kill the microbes and bleach the material. Stone Paper requires none of these chemicals..
Stone paper is naturally tree-free, no water and chemicals are required to make it. The production of stone paper is therefore more economical and even produces 67% less CO2 emissions compared to the production of pulp paper. Moreover, stone paper can be recycled endlessly, without having to add new raw materials.
