Concept of Eco-Platform

The authors propose the concept of an "Eco-Platform", setting their sight on solving problems that have arisen/arise/will arise around the coastal areas and on the restoration of natural environments of the world as a final goal. The Eco-Platform is a floating platform on which facilities are installed to dispose waste and sewage from land area, to generate heat/electric energy, to reproduce industrial resources/materials from discharged waste and sewage and to purify eutrophic sea water and contaminated sea bottom sediment. All the facilities and functions are integrated systematically to achieve no fossil energy introduction, cascade use of heat energy, efficient use of low-energy heat energy for applying marine bio-technology, and to achieve the zero-emission principle. No new technologies are required to be developed for achieving the Eco-Platform. Some fundamental functions of the system have been studied for the realization of the Eco-Platform.
