Ok - this is a classic.
Read the 'news story' below. It is the siren song of sludge. The public is
told that drying sewage sludge into pellets will make a great 'fertilizer'
that people will buy.
Claims:
Its" treated" - um....treated how exactly? Its still chock full of toxins.
It is "nutrient rich" - What they don't say is that the drying process
causes the volatilization (escape into the air) of much of small amount of
nitrogen in the material - usually leaving an over abundance of phosphorus -
which many fields are already overloaded with.
"organic" - The public is supposed to think this fertilizer will meet the
strict standards for use on certified organic farms. These pellets don't
meet organic standards and are not allowed to be used on certified organic
farms. The industry means 'organic' as in 'organic chemistry'. It contains
'organic compounds' with a carbon ring - like gasoline, or dioxins and
furans.
Oh and they think they will sell it and make money? LOL....The US and
Canada are overun with sewage sludge pellets that are so low in nutrient and
so high in toxins that no one in their right mind would pay for them. So
there isn't much market. In Toronto they had to pay haulers to dispose of
their pellets.
And the story fails to mention the risk of fires and explosions at these
sludge pelleting facilities.
Milwaukee (yup - Milorganite), Toronto, Windsor, Bronx, and three facilities
in Quebec are just a few that have had very serious explosions and fires.
This pap is the lullabye of the sludge industry. Drowse into their arms at
your peril.

FPUD will recycle sludge into fertilizer
4/26/2007 6:47:51 PM
FALLBROOK The Fallbrook Public Utility District will soon begin recycling
its nutrient-rich, organic sludge from the wastewater treatment plant into a
safe and renewable resource: fertilizer. The equipment that will recycle the
material is currently being installed at the districts treatment plant off
Alturas Road. The machinery may be up and running by summer.
The environmentally conscious decision to turn sludge into fertilizer came
about as the cost of hauling the sludge out of the county is expected to
skyrocket in the near future. FPUD currently spends $150,000 per year to
haul its sludge to Riverside County, but that location will soon close and
the nearest site will be Kern County or out of the state. But the cost of
trucking the heavy, wet sludge to those sites would be exponentially higher,
and those costs are expected to continue rising.
By heating the sludge, killing all harmful pathogens, the end product is a
sterile fertilizer that can be safely returned to the soil. FPUD can
eliminate the transportation costs and is even looking to sell the product,
at a bulk rate, to a fertilizer packager or local grower.
Sludge is the biosolid, or organic material that remains after wastewater
has been treated. District officials and the board of directors are excited
it will be used to produce a safe, renewable resource. And odor is not an
issue. The district ascertained this fact in a two-week trial run operation
last year. Visitors who came to observe and share their opinion were
enthusiastic about the process and didnt notice an odor.
Its all about being a good neighbor to the community and especially the
homes near the treatment plant, all the while, keeping our costs down, said
General Manager Keith Lewinger. This is really a win-win situation. Its
good for the environment and its good for our wallet.
The $1.7 million sludge drier should pay for itself within seven years, or
even sooner if the district is able to market the fertilizer. Heres how the
process works: Thermal fluid heated to 480 degrees produces enough heat to
dry the sludge and kill all harmful pathogens that could be present. The hot
air produced from the heating process is then cooled and thoroughly filtered
to meet Californias strict emissions standards and prevent odor from
impacting the community.
Farmers interested in entering into a contract to purchase the fertilizer
may call Lewinger directly at (760) 728-1125, ext. 1107.
