Title: Shiraz landfill as biogas power plant
In spite of the considerable achievements in the fields of waste disposal and recycling, landfills remain the major method of waste disposal across the world. With a population of 1.4 million, Shiraz generates 950 tons of waste daily. Since 1997, 2.5 million tons of waste have been deposited in the landfill, 70% of it organic and a source of biogas. The landfill began to collect this biogas in 1999. By 2008 the rate of flow was 800 cubic meters per hour. If released into the atmosphere, the biogas will cause degradation to the environment, increase greenhouse gases and pose fire and explosion risks. Instead, a biogas-fueled power plant with a capacity of 1065 kilowatt hours was launched. This decreases greenhouse gases in line with the requirements of Kyoto Protocol and provides alternative energy.
