Thermo-electric generators (TEGs) have been identified as promising solid-state devices to recover exhaust waste in internal combustion engines (ICEs). As the TEGs are able to convert heat directly into electricity, they can be used to down size the alternator of the ICEs. However, the addition...

Buildings in hot and humid climates spend more than 60% of the total energy cost for Air Conditioning and Mechanical Ventilation Systems (ACMV) to maintain the required thermal comfort for occupants. The required air conditioning load drastically increases with the fresh air demand of the...

Concerns about costs and greenhouse gas emissions are increasingly becoming major driving forces towards a greater efficient usage of energy for wastewater treatment. This article describes a few initiatives for energy saving and energy recovery within the wwtp, aiming towards and beyond Zero...

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 objective of this paper is to assess the techno-economic viability of the use of fuel cell as an alternative technology for landfill gas energy recovery. The case of an Italian municipal solid waste landfill is analyzed. The landfill was opened in 1998 and in 2001 the energy recovery...
