| #D010 | Biosolids | Biosolids are the nutrient-rich, organic materials resulting from the treatment of sewage in a wastewater treatment facility (i.e. treated sewage sludge). They are a beneficial resource, containing essential plant nutrients, organic matter and are recycled as a fertilizer and soil amendment. Biosolids are the solids that have come through the final stage of wastewater treatment, Solids Processing. | high | |
| #D011 | Land application | Land application (also called “recycling”) returns nutrients to soil that are removed when we harvest and consume food. | high | |
| #D012 | Pelletization | Biosolids are heated to evaporate water content, producing a finished material that is 90% solids or greater. | high | |
| #D013 | Chemical stabilization | Chemical stabilization does the opposite of composting because it decreases rather than accelerates bacterial activity. | high | |
| #D014 | Alkaline Stabilization | The most common form of chemical treatment consists of mixing biosolids with lime. This process, called Alkaline Stabilization, controls pathogen levels by increasing temperature and pH. | high | |
| #D015 | Pellets | dust-free, low-odour pellets 2 to 4 mm in size that can be stored for long periods of time. | high |
