The treatment of municipal solid waste aims to recover reusable raw materials. TPA Atlantic has special facilities designed to recycle solid city waste. The purpose of the process is to separate recyclable materials located in the dry fraction of urban waste. By means of an automatic sorting system and with the manual selection support, various materials are separated and then treated with different systems. Non-recyclable material is then used for grinding to facilitate the disposal process that is usually done by combustion to create energy.
