No, compost is made from 100% yard waste.

Up until 2011, the City used to mix biosolids (wastewater sludge) with yard waste on half of the Cinnamon Ridge site. The biosolids compost met all strict health guidelines mandated by the Organic Matter Recycling Regulation and was certified as Class A Compost (compost that can be sold to the general public). 

Even with meeting the highest standards, the City chose not to make the biosolids compost available to the general public and was used internally by various City departments.

The City no longer uses biosolids at Cinnamon Ridge.
