Biosolids, the nutrient-rich organic materials resulting from the treatment of domestic and industrial sewage, have steadily becoming more accepted in the city of Sioux Falls in South Dakota. Since 1995, the city has been turning a sludge into a valuable resource that is beneficial to farmers. These are given at no cost to farmers who […]

With renewable energy gaining more traction in the race to replace fossil fuels, one alternative source comes from biogas. What makes biogas a viable option is that it can be processed from biosolids, however, some challenges remain. Biosolids alone are not enough to provide the higher yield rates needed to make biogas production more commercially […]

One of the unfortunate consequences of mining is that the land that is left after all the minerals have been extracted is usually no longer fit for vegetative growth. For decades mining companies have tried to find ways to rehabilitate these tailings or mine dumps and regreen them. One possible solution came in the form […]

Biosolids, a sewage treatment by-product, have long been used as fertilizer for agricultural lands because of its rich nutrient content. However, with the increasing waste that comes with a growing population, alternative uses for biosolids have been explored by the city of Vancouver. In 2015, the region’s five wastewater treatment plants produced 51,967 tonnes of […]

Wastewater is generated by households, commercial businesses, and the industrial sector. It must undergo treatment before it is deemed safe to be discharged into water systems. Biosolids are a by-product of this process. They are primarily organic materials that can be recycled into fertilizers or used as soil amendment. Although biosolids regulations in different Canadian […]

Wastewater from household and industrial facilities yield primarily organic by-products known as biosolids. Biosolids possess many beneficial qualities that render them as useful for agriculture and alternative energy production. They contain nutrients that improve the soil quality and also have fuel properties that can be used to generate energy. Biosolids are analyzed and regulated to […]

A sound biosolids management program is necessary to ensure a healthy citizenry and a safe environment. The local government must work with the community in developing strategies for the collection, disposal and recycling of domestic waste. Municipal wastewater, when properly processed and treated in a treatment facility, can be recycled into biosolids and applied to […]

Biosolids can play a key role in providing cheap organic fertilizer for agriculture, yet a significant portion of municipal sludge that is not reused as biosolids are disposed of in landfills. Failure to recognize the advantages of biosolids as a natural soil enhancer not only translates to wasted resources but has resulted in the filling […]

The use of biosolids on agricultural land has many proven benefits. However, strict guidelines must be followed in order to protect human health and the environment. In Canada, The Ministry of Environment (MOE) sets the criteria before biosolids are considered suitable for farming. The exact location where the biosolids will be spread must also be […]

Fecal matter found in sludge and biosolids have been used as fertilizer for agriculture for many years. But before it is applied, it must pass strict regulatory guidelines to limit the number of coliform organisms or pathogens in sludge. This is important because if these biosolids are not treated properly, it could contaminate crops and […]
