5 Dr. Haiko Pieplow BMU May 13th, 2011, BerlinVideo Conference Berlin/St. Petersburg zero emissions cities blue economy

6 Dr. Haiko Pieplow BMU May 13th, 2011, BerlinVideo Conference Berlin/St. Petersburg Reality Challenge 1: economic efficiency of waste water system of St. Petersburg

7 Dr. Haiko Pieplow BMU May 13th, 2011, BerlinVideo Conference Berlin/St. Petersburg waste of resources, power and money

8 Dr. Haiko Pieplow BMU May 13th, 2011, BerlinVideo Conference Berlin/St. Petersburg Volume l/(P*year) Urine ~ 500 Feaces ~ 50 (option: add biowaste) Greywater N~ 4-5 ~ 3 % ~ 87 %~ 10 % ~ 34 % K ~ 1,8 ~ 54 % ~ 12 % P~ 0,75 ~50 %~ 40 % ~ 10 % COD~ 30 ~ 41 % ~ 12 % ~ 47 % Reuse / Water Cycle Treatment Fertiliser Terra Preta Composting Treatment Yearly Loads kg/(P*year) fertile Soils Flushwater can be saved

9 Dr. Haiko Pieplow BMU May 13th, 2011, BerlinVideo Conference Berlin/St. Petersburg If there is one problem, look for other problems and solve them together: Problem: Lack of efficient low cost sanitation Other Problems: Water scarcity Weak soils, erosion, Missing food security Lack of income Too few jobs Waterless Soil production (Urban) gardening Jobs with the systems, greywater in gardening, black soil makes water, food, happiness and health
