Circular Economy in Wastewater Treatment Plant—Water, Energy and Raw Materials Recovery

Nowadays, the main challenge for industrial and municipal enterprises is related to tightening regulations recommendations regarding environmental protection, which have been included in circular economy (CE) package. Enterprises from all sectors, including water sewage management, are obliged actively participate CE transition. Modern wastewater treatment plants (WWTPs) should include actions aimed at a more sustainable use of available resources (water, energy, raw materials) contribute protection natural resources. In this way, they can be treated as resource facilities. This paper proposes conceptual framework ‘Wastewater Treatment Plant Future’ that includes several technological solutions take into account management waste streams generated WWTPs, such (WW), sludge (SS) ash (SSA). Many already taken modernize build WWTPs respond current future challenges protection. case Future’, recovery water, energy materials strongly recommended. The implementation analyzed facilities incorporated many strategies policy frameworks, national international (including European) documents. proposed could indirectly satisfying significant technological, social needs generations, line with sustainability principles.
