- As it grows, hemp absorbs heavy metals including radioactive ones and pushes them into its leaves. If you run a harvester over the plant tops, you can collect the leaves and sequester them. You will have a large volume of material which must be dried to reduce the volume. Then it must be bagged/baled for disposal. I recommend a metal smelter for that. For this work, the hemp need not grow longer than 75 days and you might get two crops a year. Winter hemp has been done, but it is dormant in the winter. Hard freeze kills hemp.The stalks might not be very contaminated and might be suitable for animal bedding or hempcrete so you might get something to pay for the work. It must be studied to be sure.Any coal-fired power plant produces radioactive fly-ash so it may be possible to send material there. Fly-ash containment ponds are radioactive, probably no more so than your leaves.Hemp is being used in this way at Chernobyl to remove radioactive Cesium from the topsoil. Fukushima is said to be studying the method for their solution too. Notice that both of these are dealing with surface pollution, not buried pollution. The method could remove any toxins or heavy metals.Hemp roots go down 2 feet, sometimes as much as 8 feet. Below that level, I doubt the method would help. You would have to study the root depth in your cultivar and soils.Paul Stamets is a noted mycobiologist (studies mushrooms). His book, “Mycelium Running” available on Amazon describes in chapter 7 “Mycoremediation” how mushrooms do much the same thing so you might combine the two methods. Use hemp to draw it up and use mushrooms to consolidate it from the dried leaf material.Paul’s book also describes Mycofiltration in Chapter 5 where he cleaned up a stream runoff, but that was manure.It depends on how deep your material is, but you could concentrate on some water run-off from the land-fill or leachate pumped to a bed of hemp core bedding and mushrooms.I am sure some graduate student would love to do that project.The Federal Farm Bill of 2014 only allows “research farming” of hemp, but this is clearly a research project of many years’ duration. I suggest you work with your department of agriculture and its research stations. Sounds like the feds should pay for it anyway.This BTW, is a serious problem at Federal labs at Hanford, Oak Ridge and South Carolina so you might find some help there.Good luck in your efforts.
- Thank you for reaching out. You are definitely on the right path as hemp has so many benefits. Growing Industrial hemp does help purify the earth it’s grown in.
