An interesting application might be the grow media for hydroponic farms. While visiting an aquaponics farm it seemed the grow media was styrofoam based which didn't seem quite right. An organic based solution that's also biodegradable would seem much better/safer.

As for the safe part, the concentration of plastics in the nutrient solution might be a tad higher, but the plant will only pick up a small fraction or none of it so there aren't any big health concerns on that front.

- belval 5y agoNot really no, more in the sense that plants growing in a field with more lead (not lead contaminated, just above-average) might pickup a bit more lead from the soil and still be good for human consumption.
