EXPLANATION
OF CHANGE FROM AIR CURTAIN DESTRUCTOR TO TRASH
GRINDER FOR COMPOSTING AT FROM
Mr. Ron Weatherman presented
this information to the board. Three years ago the County began to
look at ways to reduce the wood waste at the landfill. Several
sites were visited and considered several alternatives. The
decision was made to go with the air curtain destructor at that
time, Weatherman said. The law was not specific about counting the
tonnage of the wood waste towards recycling goal, and the recycling
goal had not been set at that time. The State of North Carolina
has not said the county needs to recycle 25% of its waste stream.
The air curtain destructor was explained by Mr. Weatherman.
It was planned to take the ashes and work it into compost which
makes a good amendment to the compost, he said. In the late fall
of last year, the State said the landfill could no longer receive
yard waste as of January 1, 1993. The county was grandfathered on
this requirement until the new facility is completed.
A tub grinding operation has been considered. Most counties
have now gone to or are going to tub grinders in North Carolina.
The tub grinder, which is more expensive, will grind all the wood
waste except the treated waste, most of the stumps that are
received (stumps are not received now, but could be with the tub
grinder). Weatherman said the County is committed to making a good
compost at the landfill. He has been working with an official from
NC State College to develop a good compost which is at the top of
the priorities on what to do with waste.
Mr. Weatherman said this seemed to be the way to go rather
than an air constructor. The only thing that can be used out of
the air curtain is the ashes themselves, which will contribute
nothing toward the 25% recycling requirement. The tub grinder will
make the compost and return it to the public. It may be free or
charged for, which is a decision to be made by the county
commissioners. The amount that goes back out to the public can be
counted toward the recycling goal, Weatherman said.
In addition the tub grinder is a mobile machine that can be
taken to Mooresville to grind yard waste which can be done in
Mooresville and returned to the Mooresville citizens as compost
without having to haul it. Mr. Weatherman believes the County will
be able to dispose of all the compost materials.
Chairman Haire inquired about the difference in the price.
Mr. Weatherman said the air curtain would be about $82,000 which
was budgeted. The tub grinder will be around $160,000. Funds are
available for this that were saved when the money was borrowed on
the new loaders. They did not spend all the funds that were
available for this purchase. The savings there and the $82,000
budgeted for the air curtain will give enough money to purchase the
equipment, and Mr. Weatherman recommended that the County go with
the tub grinder.
Commissioner Stewart inquired about the maintenance and upkeep
of the tub grinder. Mr. Weatherman said the way he understands it
the hardface hammer drives have to be replaced. A replacement set
of knives is about $800. He does not know how often a replacement
will be required. It will depend upon the volume.
MOTION from Commissioner Madison to move in the direction of
a tub grinder concept.
