Optimization of batch bio-H2 and methane production from raw cheese whey
© European Compost Network ECN e.V. (6/2012)
Due to the renewed interest of finding new sources of green energy, biologically produced hydrogen (bio-H2) from biomass and mixed cultures is a promising alternative. Under anaerobic conditions, a wide range of food wastes can be used as substrates to generate bio-H2.

Operation strategy of grease and municipal sewage sludge co-digestion: Results of continuous trials
© European Compost Network ECN e.V. (6/2012)
To this day, biogas production on wastewater treatment plant (WWTP) and use has not been optimised, as in many cases it was operated as a means of stabilising sludge, and not recovering energy. Furthermore, many sectors of activity lead to the production of different types of organic wastes. For these reasons, co-digestion strategies are considered a good way to enhance anaerobic digestion performances and the production of biogas (Mata-Álvarez et al., 2000). Grease is a waste produced on WWTP and usually disposed of. Further Authors: R. Cano - University of Valladolid A. Nielfa - University of Valladolid

The Barriers to the Successful Development of Commercial Grid Connected Renewable Electricity Projects in Australia, Southeast Asia, the United Kingdom and the United States of America
© Lexxion Verlagsgesellschaft mbH (12/2011)
What are the barriers to the development of commercial grid connected renewable electricity projects? This article examines the technical, economic, political and social barriers to such renewable energy projects with a specific focus on Australia, Southeast Asia, the United Kingdom, and the United States of America. With the advancement of renewable energy becoming increasingly linked to climate law and policy developments; the article explores the institutional challenges, economic barriers, regulatory hurdles, and social attitudes impacting, and often slowing, the diffusion of cleaner sources of electricity supply. The article also provides an overview of the core drivers and barriers in the above jurisdictions.

The Baltic Sea region has the potential to become a pioneer in the transformation towards an ecologically sustainable economy.

Production and utilization of Biogas in Jelgava subregion and the Study and Researh Farm Vecauce
© Agrar- und Umweltwissenschaftliche Fakultät Rostock (11/2011)
Study and Researh Farm (MPS) Vecauce was founded in 1921 and serves as the unique centre for research and educational activities for students of Latvia University of Agriculture (LLU), for pupils from agricultural colleges and all interests in advanced agricultural production. Biogas production was started in MPS Vecauce in 2008, when the first biogas plant (electricity 260 kW, heat 356 kW) utilizing plant biomass was comissioned in Latvia.

Bioenergy for a regional value added in rural regions – results of the technologically-economic research to the competition Bioenergy Regions
© Agrar- und Umweltwissenschaftliche Fakultät Rostock (11/2011)
Renewable energies not only have the potential to contribute to the reduction of greenhouse gas emissions and the enhancement of energy security, but they also offer chances for regional and rural development like the creation of new employment opportunities and increasing regional income. Especially for these regional effects bioenergy plays a significant role.
