Dear Ruediger,

I surely am not an expert, but found these references by googling.

I hope this will be of help.

Best regards and thanks for your endorsements

Tom

Dear Tom,

Thank you for your afford. Nice to hear from you again and I highly appreciate your input across the faculties.

A few of these articles I already knew before. Other are quite novel to me. Basically, I look for a real practical approach and advise how to handle large amounts of such reeds in a state-of-the-art industrial facility. Practical articles describing experience with real plants, as it was typical for German Technical Notes about 20 years ago, are now very rare.

kind regards

Hi Ruediger,

it depends on which metals your are dealing with Copper and Zinc may not be too much of a problem, and finished product can be used as a supplement in soils that are deficient in these metals. Other metals are less easy to dispose of. If you get a good compost mixture it should end up alkaline around pH 8-8.5 which will immobilise metals and depending on residual concentration might make intermediate cover for land fill etc.

Hope this helps

Cheers,

Richard

Dear Richard,

thank you. I know that most transition metals (except members of the zinc group) are commonly capable to form more or less water insoluble metal hydroxides, which reduces considerably the leach-ability.

Thank you and kind regards

Rüdiger

I needed a reed source with a bio-fertilizer
