This is a very interesting concept in the context of the old saying that one
man's meat is another man's poison.
One species' meat is another species poison.
What is a nutrient? That depends on the species being fed. Common lawn
grasses have a mineral absorption profile which is 3-4 times that of some
plants.

What about marine fauna and flora? Can anyone comment?
********
The volcanic-glacial deposits of BC are often not soil because they have not
had enough time to become soil. At most they can be called soil parent
material. But all are probably MINERAL NUTRIENT deposits. I don't know of
any deposit of natural mineral dust which would be toxic to all species.

Details:
Closing the loop for nutrients in wastewaters (municipal sewage, animal
wastes, food industry, commercial and other liquid waste streams) is a
necessary, sustainable development objective, to reduce resource consumption
and greenhouse gas emissions. Chemistry, engineering and process integration
understanding are all developing quickly and new processes are already
coming online. A new "paradigm" is emerging, globally. Commercial marketing
of recovered nutrients as "green" fertilizers, or recycling of nutrients
through biomass production to new outlets such as bio-fuels, is starting to
happen.
This conference will bring together the various waste stream industries,
regulators, researchers, R/D and process engineers and commercial managers,
to develop intersectorial understanding and joint projects for phosphorus
and nitrogen recovery and reuse from waste waters.
Abstracts are solicited in particular in the following areas:
§ Phosphorus and nitrogen recovery from different wastewater sources
§ Process design and plant integration
§ Marketing and use of recovered nutrient products
§ Struvite, K- Struvite and calcium phosphate precipitation
§ Ion exchange nutrient recovery processes
§ P-recovery from biosolids incineration ashes
§ Leading-edge research and innovative technology
In addition, there will be an Open Session, devoted to "new thinking" for
this emerging paradigm, in concert with an expert panel discussion. Dr.
James L. Barnard (2007 Clarke Prize) will be the Keynote Speaker and will
address the audience during the Plenary Session, on the opening day of the
conference.
The Conference Programme will also offer visits to phosphorus recovery
installations (Ostara/UBC struvite recovery process) recently commissioned
in municipal sewage works in Edmonton, Alberta.
ABSTRACT DEADLINE: March 28th, 2008.
