FAQ

Is stone paper completely degradable?

Stone paper consists of the following components only: Calcium carbonate and high density polyethylene. If it is no longer needed, there are various disposal options. Stone paper begins to dissolve under constant sunlight after a few months. After about a year it will be dissolved in dust completely – similar to eggshells. Stone paper can also be burnt without creating toxic gases. For this reason, it is particularly suitable for the typical consumer product carrier bags.

What is stone paper made of?

80% limestone powder and 20% HD polyethylene. Limestone, one of the most abundant raw materials, comes as a waste product from quarries. The plastic, which serves as a binding agent, can be obtained from old plastic bottles, from maize or sugar cane waste.

Can stone paper be printed just like paper?

Rock Paper can be printed just as easily as conventional cellulose paper. There is even less ink required. Offset, Digital and UV printing are the ideal technologies for printing stone paper. Laser printers are rather unsuitable because they often develop strong heat. Stone paper starts to deform at 65 degrees Celsius.

Is stone paper more environmentally friendly than plastic?

Yes, stone paper is more environmentally friendly than plastic. If plastics are not recycled they practically do not rot – unlike the paper substitute stone-paper. After several hundred years, plastic products will still be found in forests and oceans. Stone Paper contains only 20% of the plastic HD-PE (high density polyethylene). It consists of carbon and hydrogen atoms and burns completely to CO2 and water.

Can stone paper be printed just like plastic?

Rock paper can be printed just like plastic. There might be other printing methods used, nevertheless the result is just as good. Offset, Digital and UV printing are ideally used to print Stone Paper. Laser printers are not suitable as they often generate high heat. Stone paper can only withstand temperatures up to 65 degrees Celsius.

How long does stone paper last?

A big advantage of Stone Paper is that it does not become yellow. Even without the use of bleach, it is beautifully white and remains so. Moisture cannot harm the material. That is why the “paper” can in principle last forever. Unless it is exposed to permanent sunlight, because under prolonged sunlight, stone paper will decompose after a few months.

Is the production of stone paper environmental-friendly and sustainable?

Is stone paper more sustainable than recycled paper?

Yes, stone paper is more environmental-friendly and sustainable than recycled paper. Hardly any fresh fibres are needed to recycle paper, but a lot of drinking water, bleach and other chemicals. There is still a lot of waste, more than in the production of virgin fibre paper. Moreover, because of its appearance, eco-paper is not suitable for all applications.

Where can you buy stone paper?

Nowadays, you can buy it everywhere, because it is sold worldwide. Horizonte VP offers the classic stone-paper bag as an ecological advertising medium. In addition, we also offer numerous other products made of this miracle material.Stone paper is produced in Taiwan, China and Sweden.

Is Rock Paper more expensive than traditional paper?

Yes, Rock Paper is more expensive than the well-known cellulose paper of the same weight. However, buying Stone Paper products as an alternative to paper or plastic products can make a major contribution to environmental protection. In addition, stone paper has many positive properties that conventional paper does not have: it is water-repellent and tear-resistant.

Can Stone Paper be written on?

Of course Stone Paper can be written on. It is even a completely new writing sensation, as the pen – regardless of whether it is a ballpoint pen or a pencil – floats over the paper. The reason for this is the velvety, smooth surface. Compared to conventional paper, stone paper is fibre-free.

Is stone paper suitable for outdoor use?

Stone paper is suited better for outdoor use than any other paper product. It is water-repellent and can therefore also be used in rain. It is flame-retardant and can withstand temperatures of up to 65 degrees Celsius and -40 degrees Celsius. This means that it is also suitable for the polar expedition.

Is stone paper completely free of trees?

A clear yes! In the production process of stone paper, not a single tree is cut down. The paper replacement product contains no cellulose and is 100 percent Tree Free! Stone Paper is not really a real paper. However, due to its paper alike look such as its sphere of application, the product is called stone paper. And because no tree is cut down, it is more environmental-friendly than cellulose paper.

Could the worldwide demand for paper be covered by stone paper?

Not with the current technology, because the proportion of the supplied plastic is too high. Worldwide paper production is around 400 million tons. One fifth of this (this is the proportion of plastic supplied) corresponds to an additional 80 million tonnes of plastic required. Both conventional plastics and bio-plastics cannot cover this demand.

Is Rock Paper toxic?

No, Rock Paper is not poisonous at all. It is even certified for food. No bleaching agents, alkalis or other chemicals are used in the production process. It contains no plasticizers like many plastics. The only constituents of stone paper are limestone and environmental-friendly HD polyethylene. The latter is produced by the polymerization of ethene – a gas which is released from various types of fruit.

What does cradle to cradle mean and what does Stone Paper have to do with it?

Stone paper is Cradle to Cradle certified. The Cradle to Cradle principle does not exhibit waste. In other words, products are made out of materials that are already available. Stone paper is produced from limestone powder, which is a secondary product of quarries and is recycled here. The second basis for the eco-paper is HD-polyethylene (high density polyethylene). This can be obtained from organic waste such as sugar beet.

What other applications for stone paper are there?

In addition to the classic stone paper bag, there are many other applications for this innovative material, especially in the field of advertising materials. Almost everything that can be made from traditional paper can be replaced by stone paper. In addition, a kind of stone plastic can be produced by slightly changing the recipe. For example, a Swedish company produces milk bags and other ecological plastic packaging from 40% lime flour and 60% HD polyethylene.
