    The Global Environment Centre Foundation (GEC) is an entity that supports the UNEP’s International Environmental Technology Centre (IETC), based in Japan. GEC is dedicated to the transfer of environmentally sound technologies, in both developing countries and countries with economies in transition. The foundation aims to contribute to Japan’s international efforts on the environment, sharing project collaborations as well as promoting Japan’s rich conservation knowledge and experience in developing nations.

  • Roots MVR Evaporator

    Type: 
    Product

    1. The main principle of Mechanical Vapor Recompression (MVR) is a direct compression of the evaporated vapor to higher pressure thus temperature so it can recycle energy for the heating process in the Evaporator which results is a low consumption of energy. 2. MVR is a distillation process where evaporation of sea or brackish water is obtained by the application of heat delivered by compressed vapor. The MVR system is an energy efficient solution since only 50KWH of electric power per ton of fresh water is required which is merely 5% of required energy for boiling water.

  • Gas Separations With Redox-Active Metal-Organic Frameworks

    Type: 
    Product

    With over 100 million tons produced annually oxygen (O2) is among the most widely used commodity chemicals in the world -- and the demand for pure O2 could grow enormously due to its potential use in processes associated with the reduction of carbon dioxide emissions from fossil fuel-burning plants. The separation of O2 from air is currently done on a large scale using an energy-intensive cyrogenic distillation process. Zeolites are also used for O2 / N2 separation however this process is inherently inefficient as the materials used adsorb N2 over O2 with poor selectivity.

  • Solving Global Water Shortages

    Type: 
    Product
    Technology:

    One third of the world’s population lacks sufficient water. The World Health Organisation predicts that by 2050 over two thirds of the world’s population will face severe water shortages. The effects of water shortage are well documented: food shortage poor health hunger and disease.

  • Thin Film Composite Membranes on Ceramic Substrate for Dehydration of Organics via Pervaporation

    Type: 
    Product

    Isopropanol (IPA) is an important solvent and cleaning agent with wide applications in semiconductor microelectronic and pharmaceutical industries. IPA is primarily produced by combining water and propene in a hydration reaction. The IPA produced is usually in a mixture with water and distillation is used to obtain IPA with 87.9% purity. Higher purity IPA can only be achieved through azeotropic distillation with cyclohexane or diisopropyl ether. In both cases large amount of energy is used for the purification process.

  • Valorisation Énergétique des Huiles de Vidange par Incino-gazeification

    Type: 
    Publication
    Publication date:
    Objective:

    L’industrialisation des pays en voie de développement engendre l’augmentation des déchets liquides que sont les huiles de vidange, tout en se heurtant au problème de déficit énergétique. D’autre part, elle s’accompagne d’une forte croissance démographique qui accentue et augmente la quantité de déchets, particulièrement les déchets ménagers solides. Ce qui constitue une réelle menace pour l’environnement et les populations.
