The precise energy savings for any given waste stream depends on its composition, according to Jeffrey Morris, an economist and environmental consultant with Sound Resource Management Group Inc. in Olympia, Washington.
For a given waste feed-in flow considered in our computation of about 110 kg/h the power output obtained is about 50 kWel.
The optimum exergy efficiency and overall capital cost are 13.98% and 129.28 × 104 USD, respectively, under the given waste heat conditions.
The exergy efficiency, total heat transfer capability and turbine size parameter are selected as three objective functions to maximize the exergy efficiency, and minimize the total heat transfer capability and turbine size parameter under the given waste heat conditions.
The exergy efficiency and overall capital cost are selected as two objective functions to maximize the exergy efficiency and minimize the overall capital cost under the given waste heat conditions.
The thermodynamic parameters of the supercritical CO2 power cycle is optimized with exergy efficiency as an objective function by means of genetic algorithm (GA) under the given waste heat condition.
The model was applied to analyze the effect of two different ambient conditions, namely, hot and cold ambient condition, and four different airflow rates such as 1.5, 3.0, 4.5, and 6.0 m3 m−2 h−1, respectively, on the temperature distribution and organic waste degradation in a given waste mixture.
To assess the recycling potential of a given waste, it is important to select a tool capable of giving clear indications either way, with the least time and work consumption, as is the case of modelling the system properties using the results obtained from statistical design of experiments.
Feed given, waste feed and the resulting net feed intake were registered daily.
Another possibility is to use a modified organism that grows on a given waste-related substrate that can be preferentially (or exclusively) used, and may be degraded, by the synthetic organism.
