Talk:Stone paper

Comparison with standard paper
There is a curious mixture of metric and non-metric units in this section and it does not fully agree with the reference. Biscuittin (talk) 20:34, 16 March 2013 (UTC)

There is also no actual comparison in the Comparison. From the preceding section, we know it contains no wood pulp, as it is made from calcium carbonate and HDPE. Still, those materials do not magically spring into existence ready to use. How many BTUs does it take to make a ton of stone paper? What solid, liquid and gaseous waste results from the manufacture of the raw materials (one of which is a petroleum product)? Without at least some facts on both sides of the scale, this section smacks of hand-waving. UglyMood (talk) 20:45, 16 May 2013 (UTC)

I have acted on this discussion. Not only was it not a comparison, and it can be argued whether a comparison to wood paper is at all relevant due to the quality differences, but should a comparison of emissions be made it should be made on a basis of equal densities, i.e. 1.6 kg stone paper to 1 kg wood paper.

For Wikipedia to treat this product more fairly, the issue suggested below should be handled. In terms of recycling and decomposition "stone papers" compare badly with "wood papers" because they are part "stone" powder and plastic. When this 'paper' reaches end-of-life, it will either be recycled or discarded. If recycled, the user may inadvertently place this plastic paper in with paper pulp products, thereby contaminating the recycling stream. If this paper is placed by the user in with plastics, when the plastics are sorted on a trommel with human assistance, they will likely end up in the paper recycling stream. Also, the high stone content and low plastic content means that this "paper" will contaminate the plastics recycling stream, too. The manufacturer of these papers claims that they will break down and degrade under UV light. The HDPE does degrade, but only into smaller pieces of HDPE. There is no "bio"degradation of plastic. If buried in a landfill, away from UV light, this "paper" will stay intact indefinitely. Even when considering all of the energy and emissions that go into making regular paper, stone paper's persistence is enough to cause worry - there is simply no good way to get rid of this product once it is made. Stone paper is not a new idea - the Japanese tried this idea many decades ago. It never caught on because it was a bad idea. This time, stone paper is coming to you because it greatly reduces manufacturing costs for the Chinese companies that produce it.

No mention of HDPE being plastic
The sustainability section seems promotional, since it skips over the fact that this material is made of plastic. Craig Butz (talk) 14:17, 9 July 2024 (UTC)
