This design by Livin Studios is to grow fungi as food out of agar. They have also designed a range of cutlery specifically to eat the fungi with. It is grown on plastic waste. The spores are impregnated into the cup shaped agar, and plastic waste is put inside. The fungi then grow in the shape of the agar, colonising the agar and digesting the plastic waste. You then harvest and eat the agar/fungi shape.
