The different waste treatment facilities of the Àrea Metropolitana de Barcelona (Environmental Entity), -storage depots, selection plants, composting plants, ecoparks, landfills, voluminous articles treatment plants- pursue common objectives:

• Maximizing the possibilities for recycling and recovery of municipal waste.
• Reducing the remainder fraction. Priority is given to a more sustainable process that enhances the recovery and re-use, which reduces the amount of waste that receives final treatment.
• Obtaining a rational and uniform distribution of facilities throughout the territory, in order to minimize waste streams and also minimize the environmental impact of treatment through fuel savings and other resources.

Map of treatment facilities

	Ecoparks: facilities that add value to REMAINDER fractions and organic matter (FORM) through mechanical biological treatments (MBT).
	Landfills : facilities where waste that can not be recovered and the remainder of treatment plants are deposited under environmental safety conditions.
	Composting plants: plants that treat the selectively collected organic matter through a biological process to generate an organic fertilizer, the compost.
	Selection p lants: facilities that separate different materials from waste using manual, mechanical, magnetic and other kind of processes.
	Voluminous articles treatment plants: storage and/or large volume waste treatment facilities, such as waste from electrical and electronic equipment or furniture.
	Energy recovery plants: incinerators where the energy and steam produced are re-used to generate electricity and supply air conditioning systems.
	Restoration with compacted waste: restoring operations with compacted waste under environmental safety conditions.
	C losed: in 2006 the landfill in Vall d'en Joan was closed, one of the most emblematic metropolitan facilities.
	Plants of transfer: temporary storage plants to optimize transport to recycling plants or endpoints.
	Storage depots: centers that selectively collect and store municipal waste that is not collected at home to facilitate recovery.
