All economic and geographic sectors are potentially affected by the benefits of the circular economy. Cities are nevertheless particularly central to these transformations because of the amplifying nature of the human concentrations present there.
This fact sheet is part of a series on innovative solutions for the sustainable city related to the circular economy.
AMETYST is a treatment unit for household and assimilated waste by anaerobic biological means (methanisation).
This process transforms part of the organic matter into biogas, which is used to generate electricity that is reinjected into the network, or heat, in particular to supply the collective network of the Grisettes district in Montpellier.
This series of factsheets has been published under the direction of the former Vivapolis network, a partnership structure initiated by the Ministry of Ecological Transition aimed at fostering synergies between players and promoting French expertise in sustainable cities internationally.
In December 2019, the Vivapolis network merged with the Institut pour la Ville Durable (IVD) to create the association France Ville Durable (Sustainable City by France). The Vivapolis sheets are now listed under the aegis of France Ville Durable.
