Nova Scotia composting plant chooses fabric covered enclosures
Fabric covering resists corrosion.
Gerald Tibbo, the Chief Operating
Officer of New Era
Technologies in Nova
Scotia, acknowledges that
there is more to composting than the
view! His company processes over
25,000 tonnes annually of source separated
organic waste into manufactured
soil which is sold to landscaping companies,
golf courses, and anyone else
who wants to get more out of the land
mass they own. The company has chosen
a building system that has added
functionality and increased profitability
to their composting process: two
polyethylene fabric covered buildings
manufactured by Cover-All Building
Systems.
New Era incorporates an extensive
aeration process to create their compost
product. An in-vessel process breaks
down the initial raw product. The secondary
curing and stabilization takes
place in a large 72’ x 440’ polyethylene
fabric covered building by means of a
forced ventilation air system. The exhausted
air is then filtered through an
elaborate Bio Filter system to maintain
negative air pressure, reduce indoor fog
and to control the indoor air environment.
The composted product is then
taken into another Cover-All building,
which is 90’ x 220’, to be further inspected,
screened for sizing and residual
removal and storage.
The reason for choosing a fabric
building instead of a conventional one
was mainly for the durable long life of
the building as well as cost of maintenance.
“The corrosive elements in this
type of environment are quite devastating
on a steel building,” says Mr. Tibbo.
The polyethylene skin is not affected by
the corrosive gases so the customized protection on the steel components of
the building is far less costly.
According to Gerald Tibbo, “things
like condensation weepage have been
easy to control. We have ordered a
number of customized improvements
from the fabric manufacturing company
to eliminate past and foreseeable problems.
The building is meeting our expectations.
The clear span working
area provides plenty of room to compost
product.”
