The total investment is expected to be $16m, and the plant is scheduled to be in operation later this year.
The plant which was acquired in late 2011 will undergo extensive upgrades.
As the facility will be equipped to sort waste materials, contractors and developers will no longer have to separate at source, and this will result in increased recovery rates.
The C&D facility will support local and provincial government efforts to divert these materials from landfill.
The new C&D facility will allow WM to mine these materials for their valuable recyclable content.
The semi-automated single stream recycling plant will process an estimated 87,000 tonnes of C&D material in its first full year.
