Waste-to-energy technologies have been being research for the past few years. WTE processes capture the energy release from municipal solid waste and use it to generate heat and electricity. These processes also decrease the volume of waste by 90% and reduce methane emissions. This can greatly reduce the number of landfills in the world and also create another source of energy. In 2011 alone, two billion tons of solid waste was produces in the world, and this number is increasing due to population growth and urbanization. Currently, only about 11% of the waste is treated with WTE technologies. The use of Advanced Thermal Treatment and biological processes are starting to increase worldwide.
