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 generate a significant amount of waste that has considerable impacts on environment and energy flow. This study aims to investigate the waste capacity of the selected district and its effect on the environment within the current waste management policy via Life Cycle Assessment (LCA)...
