It is estimated that 1500 tonnes of solid waste are generated each day in the Sanaa metro area. The city is mainly serviced by the al-Azraqayn landfill, which also serves the surrounding Sanaa Governorate as well as 'Amran Governorate. The landfill has been in operation since the 1970s and has almost reached full capacity. There is no base or surface sealing at the site, so the leachate is not captured. A facility for the treatment of healthcare waste exists at the al-Azraqayn landfill; the first of its type in Yemen, it was expected to open in March 2015, but due to the ongoing conflict and lack of electricity, the opening was delayed indefinitely.
