From biosolids to Class A compost: repurposing City of Kamloops solid waste

Sep 9, 2020 | 4:45 PM

KAMLOOPS — A build-up of city biosolids has been given a second chance, with the processed material now being used as a soil enhancer around Kamloops.

The City of Kamloops has partnered with Arrow Transportation Systems to take biosolid material to Arrow’s Ingerbelle compost facility in Princeton. Director of Civic Operations Jen Fretz says the biosolids are then processed into a Class A compost.

“Which means that it meets such high regulatory requirements that there are no limitations on use,” she explains. “In other words it can be used anywhere. It’s a soil amendment that is high in nutrients, and as you can see from the flower beds around the city, it’s a great growing medium.”

Last year, the City was trying to determine how to remove and re-use the biosolid material. A plan to have it taken to Turtle Valley was nixed and eventually the compost re-purposing option became available. The soil enhancer has proven useful so far and Fretz says the new arrangement is a good fit for the City.

“We had a bunch of material that we didn’t have a place to take for a while so it did build up at the sewage treatment centre. We’re happy to say that is almost gone, so we’re basically just back to daily production is all the material that needs to be disposed of,” says Fretz. “So $3.2 million dollars in 2020 (for costs), and about $1.2 million dollars in ongoing operational costs.”

The City adds that the Class A compost material is pathogen-free and odour-free and meets all organic matter recycling regulations.

While Ingerbelle compost is permitted for retail sale like Nature’s Gold or OgoGrow products, it is not currently available in stores.
