Toronto secures site for biosolids|
| || ||
Effective today, biosolids produced at Toronto's Ashbridges Bay Sewage
Treatment Plant will be trucked by Azurix North America to the City's
contracted landfill site in Michigan.
Azurix, a land applications business, is under contract to the City of Toronto
to store approximately 12,500 tonnes of Toronto's biosolids in Halton Region
during the winter. The material is distributed to Ontario farmers during the
spring and summer. A wetter growing season than usual last year, however,
restricted the beneficial application of biosolids by farmers, causing a
shortage of storage space.
Since January 6, the City has not been hauling the biosolids out of the
Ashbridges Bay Sewage Treatment Plant. The incinerators at the plant have
continued to handle the same amount of biosolids and the portion that was
hauled has been stored in the plant.
Azurix has now arranged for the haulage of Toronto's biosolids to the Republic
site in Michigan, at no additional cost to the City. The Republic Landfill site
in Michigan is licensed to accept biosolids and currently receives such
shipments from Windsor, Detroit and other cities. No facility closer to Toronto
was available to receive the biosolids.
Since amalgamation, the City has launched projects valued at more than $80
million to end incineration and move to a combination of land application of
biosolids and pelletization. The City has been working with US Filter to build
a heat pelletization plant at the Ashbridges Bay Treatment Plant. The
pellitization plant uses a drying process that produces pellets that can be
used as fertilizer. Pelletization opens up markets beyond land applications of
biosolids in agricultural areas.
