The City of Hamilton and Infrastructure Canada announce the substantial completion of the Biosolid Management Project, offering a long-term, sustainable solution to biosolid management at the Woodward Wastewater Treatment Plant.
For the next thirty years, the newly installed thermal drying system will use a thermal drying system which takes the nutrient-rich organic materials that result from the wastewater treatment process and turn them into pellets to be sold for fertilizer or fuel.
The public-private-partnership was supported through funding from Infrastructure Canada under the P3 Canada Fund, and the construction and continued maintenance of the new facility will be led by Harbour City Solutions.
• In 2005, the City of Hamilton undertook a Biosolids Master Plan to address the challenges associated with the existing practice of biosolid management at the Woodward Wastewater Treatment Plant.
• Biosolids are nutrient-rich organic materials resulting from the treatment of sewage in a wastewater treatment plant.
• The City of Hamilton produces about 43,000 wet tonnes of biosolids per year.
• When treated and processed, biosolids can be recycled and used as fertilizer to maintain or improve soil conditions and promote plant growth.
• The new facility will use the biosolids to produce a product, which will be sold as a slow release organic fertilizer, or to coal burning industrial facilities as a renewable fuel replacement.
• The new technology involves heating the biosolids in a large dryer drum and selling the resulting dried product.
• The project allows the City to transfer risk in processing and marketing of biosolids in the most efficient manner, providing fixed known cost over a 30-year period that was validated through a predetermined affordability threshold
