Disposable Waterproof Paper Bag Stone Paper 80gsm Grease Proofing Tear Resistant Printed For Food Wrapping

Stone paper is still in its formative years as a commercial material, but as people begin to hear about its properties it may soon become very common. In the last few years,what is stone paper?

Stone paper is a completely non-toxic, biodegradable alternative to paper. It is suited for many types of printing including offset lithography and screenprint. True to the name, Stone paper consists mostly of calcium carbonate, a substance found in rocks and is completely tree-free. The paper will degrade safely, without the exhaustion of harmful gasses, and be completely gone in 9 to 12 months if left in nature. It can also be easily burned without the release of harmful gasses.

The Environmental Impact

The most obvious difference between stone paper and traditional paper is the amount of raw material that is needed to produce the last. For producing stone paper no trees are cut and no water is used, it has low carbon emissions and it requires no acid, base or bleach during production.

Stone paper is recyclable; it needs to be recycled with Type 2 plastics because of HDPE. Beyond being recyclable, stone paper is photodegradable with 14-18 months of sunlight exposure. It’s not clear, however, what happens to the HDPE component after that process occurs.

 

Our mission
Stone Paper commits to the reduction of, among others, paper packaging to unburden our forests and fragile nature. We strive to a progressive awareness of doing business business with the collective wish to protect our environment for the future generation. We believe that everyone can make a difference, that everyone is responsible and should be an example.

With today’s knowledge about our environment no one can deny that, on corporate or personal level, action must be taken. As more companies use Stone Paper, we increase our contribution to protect the environment. By raising awareness, providing an alternative and encouraging action with Stone Paper we give companies the choice to:

Take responsibility
Preserve the environment
Lower CO2 exhaustion
Communicate their values
Connect to their clients
Create a win-win situation for all those involved

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. Also it takes consumption of 2.770 liter of water to create 1.000 kg of tree pulp paper and with stone paper any water consumption is prevented.

Energy use and carbon emissions

We take carbon emissions seriously. So seriously that we’re neutral.
It takes a lot of energy to process timber trees into the pages of a notebook. In fact, in order to produce a metric tonne of traditional paper, almost 6 times more energy is required than stone paper.
We use solar energy to power the development of our paper. Karst’s stone paper has a 60% smaller carbon footprint than regular paper.
But making our carbon footprint smaller is not enough— we need to neutralise it altogether. We invest in carbon offsets to make sure nothing we do is at the expense of the planet. This is done with a partnership with Carbon Neutral.

Waste production & recyclability

When making traditional paper, it’s not possible to convert absolutely 100% of a tree into paper. Even when making traditional paper from recycled material, solid waste is produced. To make one metric tonne of traditional paper, over 150 kilograms of solid waste is produced. When making traditional paper from recycled materials, there is even more solid waste (190 kg), as recycled paper contains more impurities. While it is possible to recycle paper multiple times, there is a finite limit— it can only be recycled a maximum of 5 to 7 times.
When making stone paper, the waste and scraps that are produced come from end cuts from rounding out the corners of pages or test batches. Much like the closed-circuit water system, stone paper produces no solid waste as the scraps can be recycled into more stone paper in the next batch. Unlike traditional paper, stone paper can be recycled indefinitely.
While the cellulose in plant fibres becomes compromised when processed multiple times, calcium carbonate remains intact, meaning it can be recycled over and over again.

Water consumption

stone paper saves significant amounts of water!
stone paper uses significantly less water to produce than regular paper. Each metric tonne of stone paper requires 27 gallons of water, which is circulated in a closed system and reused.
In comparison, those 27 gallons of water would make only 9 A4 sheets of traditional printer paper. About 15.5 thousand gallons of water are necessary to make 1 metric tonne of traditional paper. For 1 metric tonne of paper made with recycled pulp paper, about 5.8 thousand gallons are required. This is significantly less than making virgin paper, but remember that recycled material is dependent upon virgin the existence of virgin materials.
