Given the pressure to achieve the decarbonization goals and adopt circular economy models, the valorization of IBA has become essential to achieve a paradigm shift from cost to profit and sustainability.
Applying the dry approach in IBA extraction gains several economic advantages while reducing the ecological footprint of WtE plants.
By eliminating the water, the weight of the IBA is reduced by approximately 20 wt.-%.
The weight reduction can result in large transportation and landfill fee savings.
Discharging IBA in a dry manner results in the effective mitigation of the environmental impact and a high reduction in operating costs that comes along by eliminating the need to dispose of or treat the polluted water.
The dry discharge approach enables after-burning within the discharge area, which can reduce the residual Total Organic Content (TOC) in the IBA below 0.5%.
Moreover, the remaining heat in the IBA, which would otherwise be lost in the water bath, can be fully recovered.
