Waste-to-Energy in Europe
Published in Efstratios N. Kalogirou, Waste-to-Energy Technologies and Global Applications, 2017
With a total energy efficiency rate of almost 100% and an increase in energy recovery of 35% compared to the facility's old units, the Energy Tower is one of the most modern and efficient WTE facilities in Europe. The Energy Tower produces electricity corresponding to the consumption of some 44,000 households, while the production of district heating corresponds to the consumption of about 26,000 households.

An eergy tower is a clean and sustainable source of electricity capable to produce electricity day and night. In proposed plant, potable water can be recovered from the humid air which is released to atmosphere as waste from energy tower after contributing to electricity generation. The integration of proposed desalination plant with energy tower can fulfill the demand of potable water of a small community even in remote areas. Energy tower (ET) works on evaporative cooling of hot and dry air with the help of fine water spray. The cooled and dense air moves downward in large tower of length 1200 m and diameter 400 m (Altmann et al. 2005) and actuates the wind turbines at the bottom of tower with high velocity attained during the journey from top to bottom of tower. The main advantage of the energy tower is its independency on direct solar energy for electricity generation thus uninterrupted energy production can be achieved even with hourly and seasonal variation in ambient conditions. The humid air, after contributing to electricity production is released to atmosphere in conventional design can be utilized to recover freshwater by supplying it to humidification dehumidification desalination system. Liu et al. (2020) proposed a 200 m long tower for desalination based on freeze-melting process and capable to produce 27.7 kg/s yield. The power consumption for per cubic meter of fresh water was reported to be 1.07 kWh.
