Today, three billion people around the world have no access to clean drinking water and about 1.76 billion people live in areas already facing a high degree of water stress. This paper analyzes the cost-effectiveness of a stand alone small-scale renewable energy-powered seawater reverse osmosis...

This paper presents a system dynamics computer model to predict population growth, solid waste production, electricity generation from solid waste and percentage of total electricity demand supplied from the solid waste of Dhaka, Bangladesh. Simulated solid waste generation in Dhaka agrees well...

The exhaust air energy recovery wind turbine generator is an on-site clean energy generator that utilizes the advantages of discharged air which is strong, consistent and predictable. Two vertical axis wind turbines (VAWTs) in cross-wind orientation which are integrated with an enclosure are...

The use of a low temperature geothermal spring together with the heat energy still contained in waste water from the different therapy systems installed in a spa (shower, jets, bathrooms, Jacuzzis, pools, ventilation processes) can significantly reduce the operating and maintenance costs of the...

Biohydrogen production from cassava, dairy and citrus processing wastewaters (WWs) without nutritional supplementation was evaluated in anaerobic single-batch reactors at 37 °C for 70 h. Hydrogen production from cassava, dairy and citrus WW was 31.41, 37.25 and 28.95 mL g−1 of chemical...

A very large percentage of the European residential building stock is ageing and does not comply with current energy regulations. The need to complete short-term energy upgrading on these buildings in order to improve performance and meet current regulations poses a considerable challenge....
