Waste Management and Symbiosis for Waste Valorization [PDF]

Waste and Biomass Valorization, 2015
Sustainable solid waste management is a necessary prerequisite for all societies today in order to protect the environment and human health. The environmental burden caused by the high waste generation rates has to be effectively dealt with, since the link between economic growth and waste should be broken and decoupling should be achieved. Furthermore,
