Stonepaper - material & recycling

How stonepaper is made

The process of making stonepaper displayed.notebooks, diary The stonepaper 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 stonepaper 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 stonepaper.

 

The stones used for the production of stonepaper 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.

Why stonepaper is more sustainable then pulp paper

In this chart, you can see the difference in resource usage in production for both stonepaper and virgin- as well as recycled pulp paper.

Why did stonepaper receive a cradle to cradle certificate?

The stonepaper we use for our Rockbooks, is cradle to cradle certified by the official cradle to cradle Institute. The paper has a silver cradle to cradle label. On the right you can see what valuation was given to different aspects of the paper production.

Cradle to cradle literally means there is no ‘grave’ for the product after it has been used. The material does not need to leave any waste behind after usage, but can be properly recycled.

How to recycle stonepaper/Rockbook

Our Rockbooks are made from original stonepaper and can thus be recycled easily.

In theory, stonepaper is infinitely recyclable. If there were a stonepaper recycling stream, we would be able to fully re-use all stonepaper. However, in practice this still works a bit different, mainly due to a lack of sufficient volume for an own recycling stream.

We advise you to throw away your Rockbook (if you really want to), with plastic recycling (stream 2). This way, the paper can be fully incorporated in an existing recycling stream. The Calcium Carbonate (the stone that is used) is already a common additive to some plastic products and will thus be properly recycled.

What happens if a Rockbook/stonepaper enters the paper recycling stream?

Stonepaper will be recognized as a non-pulppaper product in most recycling streams that we know of. It will thus be filtered out with other products that are not recyclable in a paper recycling stream. Then, it will be processed according to the facilities rules. Sometimes this means that it will be burned, or that it will be sorted and used in proper plastic recycling. The stonepaper will in fact be recognized as a plastic-type product.

Just to make sure – we recommend you recycle our Rockbooks with plastic recycling.

Will the HDPE in stonepaper be replaced by bioplastic?

A lot of research and development is done to continuously improve the sustainability of the stonepaper and its production process.

Test are being done with bioplastic replacing the HDPE component of the stonepaper. This will most likely be a bioplastic variety that is not made from a food resource, but for example from non-consumable weeds.

At this moment, the HDPE component is made from partly recycled plastic.

Rockbooks

Where are the Rockbooks produced?

The Rockbooks are produced in the Netherlands. For us, it is very important that we know the ins and outs of the production process. This way, we want to keep it as sustainable as possible. We partnered with a Dutch production firm that operates as ecofriendly as possible and also holds an ‘ecoprinted’ certificate.
The paper we use for the Rockbooks at this moment comes from Taiwan, where the paper was invented. The paper is shipped in bulk to Europe. In the near future this paper production will also start to take place in Europe.

What is the CO2 footprint of a Rockbook?

For the On The Rocks B Corp certification, we were required to calculate the CO2 footprint of our Rockbooks. We are very happy to have this first initial figure – and will continue to reduce this footprint as much as possible.

Hardcover Rockbook: 0,36 kg

Softcover Rockbook: 0,28 kg

What new editions will On The Rocks release (blank, squared, A4)?

Our Classic collection currently features ruled Rockbooks, and three blank softcover Rockbooks.

We always plan to add further editions to our collection. Via our social media channels and our newsletter we will update you on the newest releases.

In the near future (late 2017) we will release a diary for 2018 and a bullet journal.

What happens to damaged Rockbooks?

In printing and production, you will almost always find defected or damaged Rockbooks, unfortunately. We choose not to throw these Rockbooks away. Instead, once or twice a year, we donate these books to educational projects. During Christmas of 2016, we donated the damaged books to a center for language education for refugees in the Netherlands.

Does the production of Rockbooks use renewable energy?

In printing and production, as much renewable energy as possible is used.

Currently the production of stonepaper runs on energy provided by solar panels.

The production of the Rockbooks makes use of 85% renewable energy.

On The Rocks - Organisation

When & where was On The Rocks founded?

On The Rocks was officially founded in september 2015 by Anne Pleun van Eijsden. The company is located in the Utrecht area, the Netherlands.

What is On The Rocks' mission?

Our mission is broader than just introducing a revolutionary material into the market.

The age of information and globalisation is leading to an age of distrust. Where we should be caring for ourselves and the environment, we risk losing faith in others and our capability to do so.

We flee in a digital world. In a world where we don’t know where our food comes from anymore. Where we don’t see the sources of pollution. We’re turning towards an age of individualism. An age of distrust.

But in essence, we are all social animals, dependent on the environment around us. We can easily reclaim time offline, outside of the safe space that is our home. Meeting and talking to other people. But also reclaiming privacy and the space for mystery. We can once again re-volutionize how we live together. We’ve done it before.

 

Let’s build the age of trust.
Where we live in a clean and safe environment, and care for each other.

How does On The Rocks support reforestation?

We donate 5% of our profits to a reforestation project in South Africa, the South African Reforestation Trust.

Previously we wrote a blogpost about this cooperation.
