Not sure if they were the first, or whatever, but this really seems like a breakthrough technology / methodology. How many cardboard boxes do we use a day? The mind boggles.

Totally cool stuff.

This seems more like a replacement for Styrofoam rather than cardboard boxes, though it could certainly be used in places we already use cardboard inserts. But probably still need a cardboard box on the outside. Thankfully we can grow those too!!

Dell have been using mycelium packaging for a while now - 2014 maybe? created in the US. Very interested to see this space go.

I don't think this is better for the environment than cardboard (if anything it is probably worse as a direct replacement for cardboard because cardboard already has a robust recycling supplychain). Rather, it is a replacement for plastic foam.

Under Features, it lists polystyrene products as what it replaces, not cardboard.

Cardboard is mostly renewable, it's the applications where we combine it with plastic where alternatives are needed.

This isn't different from cardboard. This is made from mushrooms, cardboard is made from trees. The real problem is plastics.
