Water and chemical engineers and environmental scientists explore three approaches to dealing with the excess sludge generated during the microbial treatment of wastewater. Their topics include fundamentals of biological processes for wastewater treatment, an oxic-settling-anaerobic process for enhanced microbial decay, minimizing excess sludge production through membrane bioreactors and integrated processes, microbial fuel cell technology for sustainable treatment of organic wastes and electrical energy recovery, and aerobic granular sludge technology for wastewater treatment.

Leopoldina, German National Academy of Science, has published a critical report on the use of bioenergy, titled “Bioenergy – Chances and Limits” .This comprehensive report is based on findings from a working committee, set up since 2010, of more than 20 expert scientists, which analyze the effective utilization of bioenergy in terms of ecological and climate issues . Although focused on Germany, it also includes global perspectives and European (EU 2020) target for renewable energy.

A gist of the report [Source : German National Academy of Sciences Leopoldina (2012):Bioenergy – Chances and Limits. Halle (Saale).]

“in quantitative terms, bioenergy plays a minor role in the transition to renewable, sustainable energy sources in Germany at the present time and probably in the future. Bioenergy requires more surface area, is associated with higher greenhouse gas emissions and is more harmful to the environment than other renewable sources such as photovoltaic, solar thermal energy and wind energy. In addition, energy crops potentially compete with food crops. The report recommends finding strategies for saving energy and increasing energy efficiency. “

Read the full report for detailed analysis of bioenergy usage to replace fossil fuels or meeting the 10 % target set by EU 2020, as well as feasibility usage of bioenergy in green house gas (GHG) emission. Also included in the report are suggested replacements for bioenergy such as solar power, photovoltaic , wind power and other alternatives which significantly impact GHG emissions and environmental friendly.

The report is also available in a concise format (in German & English).
