Schipperskaai Development cvba 4
51500 m² vloeroppervlakte – ca 400 woonunits + buurtondersteunende functies – eerste bewoning vanaf eind 2019
Circular System on District Level
Biogas
Struvite (=nutrients)
Kitchen Waste & Waste Water
Re-usable water > 30 000 m³/year
2. ZAWENT & CIRCULAR ECONOMY
ZAWENT?
ZAWENT = zero afvalwater, energie- en nutriëntenterugwinning (Dutch term)
Zero waste, energy and nutrients recovery MULTIPLE CONNECTED LOOPS

ZAWENT?
Schipperskaai Development cvba 8
TRADITIONAL: long almost linear chains
ZAWENT: short circular chains • Closed water cycle • Closed energy cycle • Closed nutrients cycle
