Divert Nova Scotia Considers Cement Kilns
Divert Nova Scotia, the tyre stewardship scheme in the Canadian province, is considering an application from LaFarge to use tyres as fuel at its cement kiln.
Divert Nova Scotia has to deal with a million used tyres every year and the existing processes are not enough.
“In some markets they make crumb that’s used in sports fields,” said Jeff MacCallum, the CEO of Divert Nova Scotia. “There’s also a company in Quebec that makes animal bedding mats for the dairy industry.”
Currently, used tires from passenger vehicles and tractor trailers are shredded by Halifax C&D Recycling in Goodwood, N.S. Some of the material is used in road construction and drainage pipes.
The company has had a contract with Divert Nova Scotia for the past seven years, but that could change.
Recycling officials may divide the material between three different proposals. The Lafarge Cement Plant in Brookfield is considering using tires as a fuel source. All proposals have to include “proven technology.”
Tires are used as a fuel source elsewhere in the world and in places where there are strict emission standards. MacCallum said the idea could be considered as long as it received the necessary permits.
