economically and environmentally sustainable. It is a mass burnt waste to energy process of converting waste into electricity or heat energy or it can also be said as "fuel from waste". It is not only a sustainable waste management solution, but also economically viable, especially for developed nations. One of the world's primary energy sources is currently fossil fuels, which account for about 84% of total electricity production [32]. Due to the rapid depletion of fossil fuel reserves, the world needs alternative energy sources, such as the WtE, to address the future energy crisis.

Baran et al. [10] indicated that energy recovery through waste incineration (a WtE technology) is an integral part of an environmentally sustainable waste management method. Nevertheless, Yay [19] indicated in his study that this method is not always economically sustainable due to high operating and maintenance costs. But, the WtE method is a way of recovering energy from waste in the form of heat, electricity (bypassing gas or steam through a turbine), or fuel [33]. WtE technologies are now considered suitable for solving waste-related issues. Impact of Sustainable construction waste management on Economy. Other sustainable approaches to the circular economy presented in **Figure 9** include:
