Dear
Sir
We are a
company with one of our activity is the waste management. Our
factories ( 25 )are located in the world but the oldest are located
in Germany
About 40% of the Organic Fraction from our factories will be converted into high quality biocompost which isusable in any agricultural sector.
The organic fractionprior to be sent into the digesters, is going thru a pasteurization process in
order to kill any unlike bacteriaas well any seed.
Thebio-compost is biologically inert, therefore we can call it fertiliser
Compost
- what it is and what it can do:
a)Compost
generated from the BioTech Process is a fertilizer in itself. Its
nutritional value of
one T. can replace approx. 50 $ worth in
chemical fertilisers.
The analysis for example of the last
samples ( it could change a bit) shows the composition of
fertilizing minerals as follows about:
Nitrogen
N 1,79
% of
which Ammonia 1,68
Nitrate 0,11Phosphor
P2O5 1,20
%Potassium
K2O 0,47
%Manganese MgO 2,04
%Bor B 0,0095
%
b)In
addition compost improves the physical soil
structure:
-
it reduces acidity (compost has a Ph value of 7 -
9), thus
reducing the necessity to add
lime,-
it increases the surface of the soil
particles, thus
improving aeration and water retention quality of the
soil,-
it prevents washing out and erosion of the
soil.
c)Contamination with heavy
metals
Below are the analysis data (in
mg/kg of dry compost) of the BioTech compost produced by anaerobic
fermentation concerning the contamination with
heavy metals. The
data have been evaluated by the Technical University of Munich and
by InstitutFresenius
near Frankfurt, one of the well known
independent testing and research laboratories. The
figures in brackets show the maximum quantities allowed by the
"German Compost Organisation".
Lead Pb45(150)Cadmium Cd 0,6(
1,5)
Chromium Cr21(100)Copper
Cu37(100)
Nickel Ni 14(
50)Mercury
Hg 0,14(
1,0)
Zinc Zn175(400)
d)Toxicity,
health hazards
Initially
already in the fermentation tank practically all health hazardous
bacteria will die in the anaerobic environment. In addition in the
technical process the compost will be heated for one hour to more
than 70 °C, which surely will kill any remaining bacteria and in
addition weed seeds etc...
As to the consumption of compost
this depends very much on the local situation. Basically it can be
used for all agricultural applications,
however the major
fields of use will be:
Agriculture
Approx. 10 t (dry material) or 25 m3 per
hectare and year can be brought into the fields and will be
consumed by the plants within one season.
Approx. 1/3 of the generated compost
quantity goes into agriculture.
Landscape recultivation, parks
This is
the second most field of application, when new parks, slopes,
abandoned landfill sites and areas along newly constructed
highways, have to be recultivated and
covered with new greenery.
Here about 1 (volume) part of compost with 3
parts of inert soil will be mixed and placed on the barren
soil.
Fruit, wine and vegetable
plantations
Up to 200 m³ per hectare are
possible
Private
gardens
Up to 50 m³ per hectare and year are
possible
For this consumer group, which consumes
another 1/3 of the compost quantity,
the compost may be filled in 20 or
50 liter bags and sold for approx. 4 times the
bulk price.
