Biodegradable foam packaging, as well has food containers, disposable cutlery, etc, has also been made from corn starch for decades.
I’m curious what the advantage of mycelium packaging is over these existing materials. Presumably, it’s not cheaper to produce? Is it mainly that the mycelium degrades faster and can be recycled more easily in home composting, etc? Or is this about creating “hard” plastic-like packaging that resists crushing, water, etc?
Theoretically fungi can live off sawdust, don't need plenty of light or watering, etc, so they should be less expensive than corn.
OTOH corn is highly optimized over centuries of breeding, harvesting, and processing. Fungi, not nearly so, so by now they may be more expensive.
