Source: 5 Wastewater plants as biorefineries

The existing municipal wastewater treatment plants can be renovated and integrated to become multi-purpose urban biorefineries that serve the citizens to treat and valorize municipal waste streams, such as wastewaters and organic waste, towards a coherent urban strategy

Combination of eco-innovative technologies with anaerobic co- digestion allow for the integrated recovery of biomethane, phosphorus, biopolymers Resources embedded in municipal wastewater Parameter Value Reusable water (m3/capita year) 75-100 Phosphorus in P precursors (kg/capita year) 0,6-1,0 Nitrogen in N precursors (kg/capita year) 4-5 Methane (m3/ capita year) 10-13 Organic Fertilizer (P-rich compost) (kg/capita year) 8-10 Cellulose (kg/capita year) 5-8 Biopolymers; PHA (kg/capita year) 2-4
