What is geoscience?

Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...

is HDPE actually biodégradable ? (en.m.wikipedia.org)

Hi all, not sure this is the right place to ask... mods, feel free to do what has to be done if not.

I'm interested is "stone paper" a kind of paper made out of calcium carbonate (from limestone or construction waste) and HDPE (High-density polypropylene).

It's been advertised as a more eological solution for producing paper as it doesn't requires to cut down trees and uses much less water and chemicals in the process, compared to traditional paper.

My concern in about HDPE (that represent more or less 20℅ of the final product). Most companies advertise it as a "non-toxic biodegradable" plastic. But I can not find any reliable information to back this up.

I'm then inclined to think it is just green-washing.

but still I'm wondering if anyone could bring some insight about HDPE being biodegrade ...

thanks !

Probably just biodegradable in industrial composting facilities unless you add HDPEase enzymes to it to break it down. But perhaps the filler material makes it less dense and easier to break apart, so easier to digest for bacteria, etc..
