Landfills are a source of methane, a powerful greenhouse gas. Biosolids are used to create a special topsoil to cover decommissioned landfills. This topsoil contains microorganisms that convert methane into carbon dioxide, a much less potent greenhouse gas. This can reduce greenhouse gas emissions from landfills by as much as 95%.
Thompson-Nicola Regional District landfills
Metro Vancouver worked with the Thompson-Nicola Regional District to use Nutrifor™ in several of their landfill closures. Nutrifor™ was mixed with woodchips and sawdust to make a compost-like material. When placed on the landfills, this material converted methane emissions from the landfill into carbon dioxide. This reduced methane emissions by 90%.
