We're not the first ones to process cellulose.

So they're spinning these tiny nano fibers of pure cellulose.

The mushrooms then are harvested, but very importantly, the mycelium has converted the cellulose into fungal sugars.

Generating ethanol from cellulose using mycelium as an intermediary and you gain all the benefits that I've described to you already.

What I'm not suggesting is that microbial cellulose is going to be a replacement for cotton, leather or other textile materials.

And because of the super absorbency of this kind of cellulose, it just takes one, and a really short one at that.

Bacterial cellulose is actually already being used for wound healing, and possibly in the future for biocompatible blood vessels, possibly even replacement bone tissue.

But to go from cellulose to ethanol is ecologically unintelligent, and I think that we need to be econologically intelligent about the generation of fuels.

I'm essentially using a kombucha recipe, which is a symbiotic mix of bacteria, yeasts and other micro organisms, which spin cellulose in a fermentation process.

Finally, I came to know it is a special cellulose derived from a pinewood, but even after that, you need a multimillion dollar plant like this to process that material. Again, a stop up.

Now, spray foam is an excellent insulator it fills in all the cracks but it is pretty high embodied energy, and, sprayed in cellulose or blue jeans is a much lower energy alternative to that.

Another promising development is bioplastics, which have begun to compete with petroleum based products in certain short lifespan applications such as packaging and agriculture over the last two decades. Given that bioplastics are produced from renewable or bio based sources (cellulose, starch, and glucose) and, in some cases, through microbial fermentation they have a lower carbon footprint, contribute less to global warming, and biodegrade to small molecules.
