Cork is displacing plastics and creating a billion-dollar industry

I once commented that HN is the most wonderfully diverse ecosystem and here&#x27;s my chance to prove myself right! I&#x27;m a cork &#x27;farmer&#x27; in Coruche, right where this article is situated. I wasn&#x27;t expecting to read a puff piece about it today. I just did my novennial harvest last year. For anyone not in the know, cork is the cork trees&#x27; bark, and it&#x27;s stripped from the tree without harming it every nine years. Undressing the tree is properly medieval work and you need to be very skilled with a hatchet to do it. Do a poor job and you&#x27;ll ruin the cork and scar the tree for decades.<p>The harvest is tough work but it&#x27;s the only well-paid trade left in agriculture. I doubt it has much future beyond fodder for high peasant magazine articles. Trees are dying left and right from multiple climate-related problems no one has a handle on. Divestment from the traditional montado like mine into intensive production units with better water management and automated extraction is the likely future. The billion-dollar outfits have started experiments with high-density groves, inspired by the olive oil industry&#x27;s success. It&#x27;s a finicky tree though, so conclusive results are taking a few decades more than you&#x27;d expect to materialise. They&#x27;re stuck having to buy cork from thousands of traditionalist family farms for now.<p>But that&#x27;s assuming the industry even grows enough to justify the investment into better plantations. Legitimate uses for the stuff apart from wine corks are scarce. We&#x27;re all hoping that our phenomenal ecological footprint will see us grow as an industry into everything from insulation and roofing to shopping bags and umbrellas (hence said puff piece I imagine). We&#x27;ll see, it really is a phenomenal material and the carbon math makes sense at the source. You can almost see the tree sucking out stuff from the air and soil to build thicker layers of bark. I joke that we&#x27;ve been doing regenerative farming for generations, we just didn&#x27;t know it until someone told us.<p>If anyone on HN is ever in Portugal and wants to visit a montado, happy to take y&#x27;all on the most boring tour of your life. But we can have a nice picnic! It&#x27;s lovely country.

Does anyone else remember there being stories in past about increased cork production being unsustainable as in not enough availability and quality was getting lower? Or am I remembering wrong.

The article is heavy on cork production, light on use cases.<p>&gt;“Compared with materials like polyurethane foam [used for thermal insulation], products made with cork require less energy and produce less CO2 emissions.”<p>Polyurethane foam is used for thermal insulation in a few places. But fiberglass is still the champion of that sector, and it&#x27;s older than plastic and more durable and abundant than cork. More often, polyurethane is used for couch cushions, cheap mattresses, and shoes, which are difficult use-cases for cork — Birkenstocks have a cult following but poor water resistance.<p>&gt;used to shield fuel tanks on NASA spacecraft and electric car batteries.<p>And this about wraps it up.<p>There are probably some good use cases for cork, but the major advantage of plastic is the ability to do so much with so little. An LDPE bag of the sort now banned in California weighs about six grams. I can&#x27;t think of many things you could do with six grams of cork that don&#x27;t involve grapes.

Now cork is experiencing a revival as more industries look for sustainable alternatives to plastic and other materials derived from fossil fuels. ... The cork oak’s thick bark adapted to defend the tree from fire, making it a powerful insulating material that’s been used to shield fuel tanks on NASA spacecraft and electric car batteries. ... Several studies found that cork is carbon negative, meaning it can store more carbon than what is required to produce it.

Weirdly I was talking to a building surveyor recently about how there are new building insulation products coming out made out of cork[1] and some made out of mycelium (fungus)[2]. So instead of insulating your walls using something like polystyrene which is pretty gross to work with (produces a lot of nasty polystyrene dust when you sand it down etc) you can have a lovely natural product that is sustainable and also has similar thermal and (istr better) flame-retardant properties.<p>[1] <a href="https:&#x2F;&#x2F;www.corkstore24.co.uk&#x2F;shop&#x2F;11-thermal-and-sound-insulation-expanded-cork-boards&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.corkstore24.co.uk&#x2F;shop&#x2F;11-thermal-and-sound-insu...</a> is the sort of thing I guess he was talking about<p>[2] <a href="https:&#x2F;&#x2F;ukgbc.org&#x2F;resources&#x2F;mycelium-insulation&#x2F;" rel="nofollow">https:&#x2F;&#x2F;ukgbc.org&#x2F;resources&#x2F;mycelium-insulation&#x2F;</a> website seems to lean into the idea that this is basically mushrooms which seems a bit weird but whatever

The global plastic market was $609B in 2022 and only growing.<p><a href="https:&#x2F;&#x2F;www.grandviewresearch.com&#x2F;industry-analysis&#x2F;global-plastics-market" rel="nofollow">https:&#x2F;&#x2F;www.grandviewresearch.com&#x2F;industry-analysis&#x2F;global-p...</a><p>Gotta start somewhere I guess.

Do Birkenstocks get credit for this? Cork makes such comfortable and durable shoes.

There are always niche alternatives to anything, here and there. But unless we&#x27;re talking about a new technology or some other fundamental change in circumstances, they are alternatives rather than the primary choice for a reason.<p>Cork has a little overlap with a few plastic use-cases, but only slightly. It requires far more effort to produce than a plastic equivalent, and is simply not suited to most use cases.<p>I do look forward to some cork alternatives to plastic where it makes sense. But I hardly expect it to make any meaningful difference to overall plastic use.

Stupid question : trees are effectively corals, pumping sugar from air with light and getting water + trace minerals from the ground. Wood&#x2F;cork is basically the dead mmtisdue extruded by the living outer layer.<p>What would it take to &quot;unfold&quot; something like a tree into a continously harvest able square with leaves and hydroponic roots still attached?

I was wondering how frequently cork can be harvested from a tree: 9 years<p>Also, it sounds like the CO2 extraction is increased in order to regrow the bark.<p><a href="https:&#x2F;&#x2F;corkhouse.com&#x2F;blogs&#x2F;blog&#x2F;the-cork-bark-lifecycle" rel="nofollow">https:&#x2F;&#x2F;corkhouse.com&#x2F;blogs&#x2F;blog&#x2F;the-cork-bark-lifecycle</a>

So another way to do deforestation! Can&#x27;t there be something made by recycling or leafs?

Curious if rubber trees have faced a similar arc of farming challenges.
