Sustainable recovery of wastewater to be reused in cooling towers: Towards circular economy approach

Circular economy approach is needed in order to move towards sustainable development. In this frame, the current work is aimed at improving the sustainability of a food industrial plant through circular economy approach, using a waste stream, coming from the washing and disinfection of bottles befor...
