  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. Obtainingvalue out of waste • Closing loops • Energy loop • Nutrient loop • Water loop • Whether a compound is defined as waste or as resource is greatly depending on the concentration
