10 Innovation of Sanitation  Sanitation moved from local to decentral, to central.  The collection of human waste is hardly innovated in more than 200 years  The transport of human waste innovated from defecation into canals, to transportation by lorry towards transportation by tubes  Treatment of human waste innovated from no treatment, towards reuse in agriculture, towards relative clean water production but also formation of polluted by-products  Contrary to innovation in f.i. communication and energy sanitation became less indivual, less sustainable and more large scale.

11 How can this be changed?  Collection, transport and treatment of organic residues based on:  Creating value out of the residues  Synergy with the surrounding environment  Using existing infrastructure if possible  Source-oriented approach

12  Closing loops  Energy loop  Nutrient loop  Water loop Whether a compound is defined as waste or as resource is greatly depending on the concentration Obtaining value out of waste
