Aside from seeweed and for potash, has this idea ever been used for this purpose? |
yep for post industrial clean up in quite a few places.( for "ore" has been tried for a few expensive metals but im not sure how successful it was)
iirc some work has been done with algae in aquatic systems as well as soil based stuff. |
Its called phyto remediation. Some plants with their associated mychoriza are good at getting rid of organics, whilst others are especially good at taking up heavy metals; they're called metalophytes. Grow them on metal waste tips, harvest, compost, dry, incinerate, collect bottom ash as metal oxides.
Tahir- this is probably one of those things where the lethal dose of kale tops is HUGE, but prolonged eating of large (but not un-imaginable) quantities could also be lethal, or at least injureous to health. Doesn't oxalic acid cause gout? |
