system and method for the achievement of the energetic and technological self - sufficiency of sea and inland ports with regard energy and water supply with the full and pollution free exploitation of the port &# 39 ; s internal resources . the system comprises of an innovative linking of existing technologies and of a method which allows sea and inland ports to be independent from external suppliers of electricity and water while at the same time it provides ports with an autonomous and pollution free system for disposing of generated wastes . this includes municipal solid and similar waste , technological waters , bilge waters ; and optionally msw generated by the local community . the system is formed by an energy distribution center and an optimal linkage of mass and energetic flows and known technologies comprising as a minimum a : 1 ) technology for substantial / energetic conversion of msw with a positive energetic balance ; technology for substantial / energetic conversion of bilge water and contaminated plastics to synthetic fuel or energy ; technology for treatment of municipal or industrial sewage and ; technology for conversion of sea and / or inland water to pot and industrial water . the system manages and distributes port &# 39 ; s internal resources in a synergistic way to achieve their optimal utilization and the “ zero waste - zero energy ” effect .
