Due to recycling and diversion activities, the number of tons of trash buried at the Miramar Landfill decreased from a peak tonnage of over 1.57 million tons in 2005 to almost 910,000 tons in recent years.
Waste generated within the San Diego city limits is also buried in other landfills (i.e., in addition to Miramar Landfill). In 2020, the overall disposal tonnage was approximately 1.54 million tons. In comparison, over 1.99 million tons were disposed of in 2005.
