Articles ´   CDM - Clean Development Mechanism in the waste management sector An analysis of potentials and barriers within the present methodological framework Grids for the future – natural gas today, hydrogen tomorrow? The use of hydrogen as an important energy carrier is an essential element for global sustainable development. However, there are many significant challenges for implementing all the components of a complete energy system based on hydrogen. Urgent progress towards the development of a full hydrogen system requires a practical strategy within the context of an existing, extensive natural gas system which has resulted from substantial capital investment over a long period of time. Reutilisation of green waste – a comparison of its recycling for energy generation purposes versus composting and peat substitution, with particular consideration of the CO2 balance. Green waste is increasingly extracted from the material recycling process and, as a result of the financial subsidy arising from the German Renewable Energy Law [Erneuerbare-Energien-Gesetz (EEG)] for the generation of energy from sustainable raw materials, it is fed into the energy recovery process in biomass power stations. Improved energy supply, waste management and climate effects by use of biogas technology in South African prison farms Energy needs for room heating, warm water and steam production in South African prisons are normally acquired from electricity produced via fossil fuels.

ASK Special   Increasing energy efficiency: A plant manufacturers view To increase the energy efficiency of the waste-to-energy plants is the main challenge of each plant manufacturer. This article lists some current trends and picks- up three of them by mean of examples from current Keppel Seghers projects. © Foto: Fotolia.com News   European Commission investigating possible illegal entry of US biodiesel from Singapore and Canada The European Commission (EC) has called for an investigation of "sufficient evidence" that anti-dumping and countervailing measures imposed on imports of biodiesels originating in the US are being circumvented by importing biodiesel consigned from Canada and Singapore at lower, subsidised prices. Denmark wants to store the wind... in bags The experiment has been carried out by engineers from the Technical University of Denmark (DTU) and basically involves injecting compressed air into large bags buried under the dunes of Jutland. The bags would be inflated using a compressor operated by wind power. Cuba investigates potential of marine thermal energy Ocean Thermal Energy Conversion (OTEC) uses the temperature difference that exists between deep and shallow waters to run heat engines. In the Bay of Matanzas on the northern coast of Cuba, scientists are experimenting with the potential of this renewable energy. Little research on OTEC has been conducted anywhere around the world to date. Content-partners... introduce themselves   Technical Co-Operation Project Bavaria-Sao Paulo   The Technical Co-Operation Project between São Paulo and Bavaria State was signed December 2004 by the Bavarian state minister Dr. Werner Schnappauf and his Brasilian collegue Prof. Dr. José Goldemberg. In a first step experts out of São Paulo were informed about practical waste management experiences as well as authorisation and controll procedures in Bavaria. Afterwards a waste management concept adjusted to the local circumstances was established for São Paulo.   to the content >>
