Waste and wastewater management and disposal are crucial environmental issues of our time. Only if we succeed in minimising or even preventing potential environmental damage, do we stand a chance of safeguarding our environment and our vital natural resources.

Against this backdrop, increasing importance is attached to the reuse of treated wastewater as well as to the recovery of valuable material recycled from wastewater treatment. Coordinating the interfaces of water and energy supply and waste material reuse is thus essential for a sustainable wastewater management and disposal programme.
