This time, the scientists took a different approach to the material formula itself. Instead of turning the fungal biomass straight into a leather-like sheet, they first processed it into a thick, wet, pulpy mass and grew it in a nutrient-rich liquid. Then the pulp was harvested, washed, and mixed with sorbitol and cellulose. Sorbitol makes it softer and less brittle, while the cellulose strengthens it, giving the material the right balance of flexibility and durability. The mixture was then spread into a thin layer and dried.

That's paper. Fungus fiber instead of wood pulp, but still paper.

In laboratory testing, the material showed durability and strength comparable to traditional leather

More durability? Less durability? Equivalent durability?

Apparently the durability is incomparable, and unquantifiable. Perhaps it is unmeasurable.

when submerged in water, it broke down after 28 days

The material still needs to be more tear-resistant before it can move toward mass production

Because you know leather is famously water-soluble. Looking forward to wearing a jacket that disintegrates in the rain.

This is paper.

They're saying that it is similar. That's literally what comparable means.

Except that it apparently tears easily, and it breaks down when wet, so... it's neither durable nor strong, especially compared to leather.

If your interpretation of the use of "comparable" in this context is correct, meaning "similar" or "equivalent", then the statement is objectively false based on the other information presented in the article.

My interpretation of "comparable" as meaning that these things are suitable for comparison is being generous to the author, assuming that they are not intentionally making a false statement.

it broke down after fully submerged in water for a month

if you're not a scarecrow it's probably going to be a usable alternative for most people

Dude, have you ever owned anything leather? This product was submerged for 28 days. https://leatheradvice.com/leather-gets-wet/

Paper is awesome, so what if it's paper. This is great news for sustainable products.

Leather can get warped and damaged by exposure to water, but it doesn't dissolve. There are many leatherworking processes that involve soaking or steaming it and I'm not sure if this material would be quite as resistant. I think it's a fine material, but it does feel a little bit misleading to present it as such a viable alternative to leather while only vaguely hinting at its actual durability and then admitting that it dissolves in water, albeit slowly. What does short term exposure look like? A hole in your faux leather jacket instead of a stain you might be able to fix?

I’ve had a leather wallet for three past ~10 years and it’s been wet a handful of times (not submerged, but things like being in my pocket when I got caught in the rain) and it still is in great condition.

"[M]eeting the needs of the present without compromising the ability of future generations to meet their own needs.”

A PieFed commuity dedicated to promoting sustainability and sustainable development.

For discussion of environmental, climate, clean energy, social, political, and individual action. A place for news, education, questions, and discussions.

Rules:

  1. Don't be a dick.
  2. If it fits an UN Sustainable Development Goal, it's probably welcome.
  3. Links to articles should leverage the original article title. Minor edits in [square brackets] for clarity/to reduce clickbait are probably fine.
  4. We all know corporations & governments are the main problem, and collective action + legislation is the best path forward. That said, someone needs to show support for a more sustainable market - to that end, discussion of individual action is encouraged, and "whatabout big oil" comments in posts about individual action may be removed with prejudice. You're not wrong, but see rule 1.

Not really a rule per se, more of a request: if the article has "Trump" or "Musk" in the title, consider posting it in a USA/Political community to help keep this space focused on sustainability over clickbait political headlines. Political posts are allowed, but discussion should prioritize policies over personalities.
