Energy is fundamental for life and the development of the society. The global energy request is satisfied from fossil fuels which are currently used as primary energy source and found economic convenience for transport and production of energy for industrial and house requests. Emerging scientific evidences are proving climate change effects from the use of fossil fuels caused by the emissions of COx, NOx, SOx, CxHx, dust and ash, produced during combustion processes and released in atmosphere. Hydrogen is receiving higher interest to avoid fossil fuels consumption and climate changing. It cannot be considered as a primary energy source but it could be transported, stored and used like other primary energy sources.

The development of a sustainable society requires reduction of dependency on fossil fuels and of the amount of pollution generated from human activities. The treatment of solid waste and of wastewater is an area in which these two goals can be simultaneously achieved. Biological Hydrogen Production is an interesting opportunity to produce hydrogen from renewable source, at low costs and sustainable environmental impacts. Hydrogen can be considered a clean energy source, compatible with electrochemical and combustion processes for the conversion to other energy forms, without production of carbon dioxide. The present research work has been set up to evaluate the potential biological hydrogen production from organic waste. Two types of sludge have been used as inoculum: granular sludge from an UASB digester and anaerobic sludge from an anaerobic digester of zootechics wastes, both heat pre-treated. The substrates used during experiments were glucose and the organic fraction of municipal solid waste.

In diesem Beitrag werden die verschiedenen Technologien beschrieben, die von Ros Roca zur Biogasherstellung, -aufbereitung und -nutzung angeboten und als Generalunternehmer realisiert werden. Die Biogas-Technologie von Ros Roca wird eingesetzt für Biomasse aus dem kommunalen, industriellen und landwirtschaftlichen Bereich. Neben organischen Abfällen werden in den Biogasanlagen auch nachwachsende Rohstoffe verwertet. Die Biogas-Technologie ist in zahlreichen großtechnischen Anlagen europaweit für unterschiedlichste Inputstoffe seit vielen Jahren im Einsatz.

To guarantee future energy supply, available and new regenerative energy sources need to be exploited. Hydrogen is a clean CO2-neutral energy source (Maddy et al., 2003), and can be produced chemically or by using biological processes. Furthermore, hydrogen can be easily stored and transported. The use of hydrogen in fuel cells is environmentally friendly because the exhaust gas only consists of pure water vapour.

Japan has been generating municipal solid waste at an annual volume of approximately 50 million tones or more since 1989 (Ministry of the Environment, Japan, 2006). Degradation of garbage is achieved either physicochemically or microbially. Most household solid organic waste is incinerated and its residue, the ash, is disposed into the landfills at present. It is a lack of disposal capacity, however with final disposal site having an average capacity of only another 13.2 years. To solve the problem it is necessary to implement the waste recycling measures, taking into account the reduction of waste, reuse and prolongation of the life of products and parts, the recycling of waste, and the appropriate disposal as the final waste.
