11. Enhanced biogas production from municipal WWTPs : Co-digestion of microalgae with sewage sludge and thermophilic secondary digestion of mesophilic digested sludge
Abstract : Biogas is produced when organic material is broken down in oxygen-free (anaerobic) conditions. This process is called anaerobic digestion and is used in most large and medium-sized municipal wastewater treatment plants in Sweden. READ MORE

12. Co-digestion of microalgae and sewage sludge - A feasibility study for municipal wastewater treatment plants
Abstract : The increased emissions of anthropogenic greenhouse gases over the last 100 years is the reason for the acceleration in the greenhouse effect, which has led to an increase of the globally averaged combined land and ocean surface temperature of 0.85 °C between 1880 and 2012. READ MORE

13. Anaerobic digestion of crop and waste biomass: Impact of feedstock characteristics on process performance
Abstract : Anaerobic digestion provides an array of positive environmental benefits such as reducing greenhouse gas emissions, replacing mineral fertilizers, producing renewable energy and treating waste. However, pitfalls in anaerobic digestion such as poor methane yields, process instability, process failure and regional shortages of feedstock have limited the full exploitation of the anaerobic digestion process.

14. Performance Assessment of Wastewater Treatment Plants : Multi-Objective Analysis Using Plant-Wide Models
Abstract : As the knowledge about anthropogenic impacts of climate change has grown, the awareness of the contributions from treatment of wastewater has widened the scope for wastewater treatment plants (WWTPs). Not only shall ever stricter effluent constraints be met, but also energy efficiency be increased, greenhouse gases mitigated and resources recovered. READ MORE

15. Anaerobic Digestion of Solid Residues on the Bolivian Altiplano
Abstract : Anaerobic digestion and the production of biogas can provide an efficient means of meeting energy needs locally and reducing organic loading due to untreated waste material in water recipients. Furthermore, residues after anaerobic digestion may be used as a fertilizer to improve the soil in many parts of the world. READ MORE
