The Regional District of Nanaimo is working toward an amendment to one of its garbage bylaws to ban commercial organics from the Cedar landfill. Alan Stanley, the RDN’s solid waste program coordinator, said it’s estimated about 30 per cent of the solid waste going to the rapidly filling landfill is compostable organic material.
The RDN and the Cowichan Valley Regional District recently commissioned a report thoroughly reviewing new residual waste management technologies. The report looked at a number of new approaches rather than traditional landfilling, including bio-fuels and fermentation. The RDN concluded none of these technologies have been proven and are expensive, with costs ranging from $70 to $217 per tonne.
The report, prepared by consultants at Gartner Lee Ltd., concluded that traditional diversion activities may be the preferred option at this time.
"A conventional but aggressive waste reduction program could divert up to 70 per cent of the solid waste stream through maximizing organics recovery in a source separation-based program," the report stated, "as well as enhancing material recovery and recycling activities."
A new berm being built at the south-end of the Cedar landfill could add seven to 10 years of use to the landfill.
