Interesting, but growing fungi requires large amounts of water, yet this resource has been omitted this input from their "impact" diagram. At scale, the "manufacturing" process for this product likely will require an insane amount of fresh, clean water. With potable water already a constrained resource in many areas, how big can a single factory be scaled before running afoul of their local community?
- jmhobbs 5y agoDoes it if you're not fruiting them though? I make 5lb hardwood sawdust bags with about a quart, quart and a half of water, and that's all that is needed for the mycelium to colonize the whole thing. I suppose at scale a liter for a 12"x6"x6" block is perhaps a bit much lot.
- drewm1980 5y agoHobby gourmet mushroom grower here. For gourmet mushrooms you use about 60 percent water. For this purpose it is probably lower. Many products require many times their weight in water; this is not that bad. Mushrooms care more about competing bacteria and fungi than impurities... I imagine pasteurized groundwater or rainwater would be good enough for this. Drying and killing the mycelium could be energy intensive depending on the local climate. Maybe they recapture most of the water during the bake... It would already be sterile.
