Re-thinking sludge management within the Sustainable Development Goal 6.2.

ABSTRACT

Sustainable Development Goal 6.2 of the Agenda 2030 is addressed to achieve access to adequate and equitable sanitation and hygiene for all. Further, one of the major principles underlying the Lisbon Charter is that sustainable and safe management of wastewaters are fundamental to the health of communities and their sustainable socio-economic development. Within this framework, the management of sewage sludge in a sustainable manner is one of the critical issues facing modern society, due to the growing rise of its production, increasing difficulties in properly locating treatment and disposal works, and complying with more stringent environmental quality requirements, thus requiring a re-thinking of its management. This paper discusses major concepts and principles for re-thinking the sludge management in order to achieve the above-mentioned objectives.
