1 Terra Preta Sanitation full reuse in sanitaton and bio-waste-management Learning from successful ancient cultures… Prof. Dr. Ralf Otterpohl

2 Initial remark on Public Health Parasites (Salt! removal of most parasites with increased uptake of pure NaCl salt over 6 weeks, combne with Vitamin C like fresh fruit also traditional knowledge) Flue (bird, swine, what is next?) why did this normal flue lieke swine flu become a WHO pandemy? Keep Vitamin D up! All flue can be treated with high amounts of vitamin D or A, check levels A really dangerous could come… (who will belive WHO then? see above) Keep the immune system strong: zink! (trace element, ammunition of the immune system, often too low)

3 Initial remark on Public Health Selling bottled water for 30 40 0r 50 cents per litre to the poorest people in the world… … is brutal misuse of power, killing babies and small children (can those who run this sleep well at night?) A price of 5 cents for water in a bag is possible

6 Low/Non-diluting toilets are the key for new sanitation concepts

7 1.Blackwater and integrated systems design 2.Dry sanitation / Low Cost solutions 3.Urine-Diversion with flush sanitation The 3 main Development lines

8 Here: Dry sanitation and a pathway for the furture: Urine diverting dry toilets have been a major step forward (first from Sweden) Over 1 Million installations, fast growing Many different toilets have been developed, good but not excellent Treatment pathway for faeces and urine needs to be improved

9 …. Urine Diverting Dry Sanitation: Developed from Sweden ROSA, EU 6th FP

10 Neue Schultoilette, Ukraine ( TUHH/WECF) NGO WECF Women in Europe and TUHH

11 Major drawbacks in modern dry sanitation: Urban, peri-urban areas are still difficult to be served Multi storey houses not well solved Ventilation is not an option for large scale, otherwise the whole region will smell bad An ancient system offers new perspectives: Terra Preta Sanitation as evaluated by Dr. haiko Pieplow, Germany

12 Bio-Systems Design: If there is one problem, look for other problems and solve them together Waste of one system is food for others Solutions are searched until no waste is remaining No Waste equals Zero Emissions Multiple added value according to Gunter Pauli, ZERI

13 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, depletion Missing food security Lack of income Too little jobs Waterless Soil production (Urban) gardening Jobs with the systems, greywater in gardening, black soil makes water, health

14 Soil degradation is stupid, future generations will need land, too… Poor soil can become highly fertile with clever management of biowaste and sanitation

15 Naturally very poor tropical soil degrades very soon with lack of organic matter The same soil: highly fertile and carbon rich over many generations long ago with - lactofermented vermicomposted biowaste and faecal matter - 10% charcoal Terra Preta Poor soil can become highly fertile with clever management of biowaste and sanitation from: Günther F. (2007). Carbon sequestration for everybody

16 Terra Preta: - 2000 – 7000 years old - around 10 % of the Amazon Region - 16. century millions of people, today 350.000 - up to 20 meters deep, partly hills - fertile without adding fertilizer - multiple yield Composition: around 10 % ground charcoal, processed biowaste and feacal matter ( lactofermentation and vermicomposting), bones and broken earthware Glaser, B.

20 An ancient pathway for today: TERRA PRETA (black soil) Production of super-fertile soils, discovered in the Amazon from ancient cultures, still highly fertile today Composed of biowaste, feacal matter, bones and charcoal Production through lactofermentation (start e.g. by EM or Sauerkraut-liquid) followed by vermicomposting

21 Four design options for Terra Preta Sanitation: Siple bucket systems with separate urine collection Adapted urine diverted dry toilet 1st Class urine diverting dry toilet (to be developed) If the flush is needed: urine diverting flush toilet, collect solids in an lacto-acid sieving unit Terra Preta Sanitation was mainly inspired by Dr. Haiko Pieplow, Ministry of the Environment, Germany

22 NO-COST-Sanitation can be highly efficient and feasible with some change of habits 1.)Teach users of pit-toilets to divert urine in any way, after learning about fertilising value many people with some space will do this very dense population: urine collection and usage should be organised then no urine, no water into pit, add some charcoal and lacto-acid-bacteria (like in lacto-sauerkraut, pickled foods) 2.)Same procedure, but instead of normal pit do 2 alternate shallow pit, put worms into idle pit 3.)Use simple bucket system with a lid that closes air-thight otherwise like above

23 Pippinette First step: Keep Urine separate opt 1.) to 3.) Norway The most simple approach, personal collector, female / male version

24 Urine collection, male version like in hospitals

25 Second step: Feacal matter collection opt. 3.) Example: Mobile-toilet toa-standard with a closing lid for the bucket after usage: cover with ½ cup of a mixture of 2,5 kg ground charcoal, 1 kg dolomite-lime, 1:100 EM A or leachate of lacto-acid-fermented sauerkraut (pickled), some stone-dust Dry toilet shop, Hamburg: Terra preta / EM-Shop: operation ok when smell is ok leave lactofermenting for minimum 3 weeks to some month, then vermicomposting in aerobic composter, Process is simple and robust,

26 A good starting point for a luxury version Separett Villa, Sweden Cover lid Cild seat Terra preata toilets need to close the bucket air-tight after usage, no ventilation needed

28 Breakthrough in solids treatment at TUHH (BMBF / IPSWaT)

29 Integrated urban bio-systems

30 Win-Win-Win-Situation Sanitaiton makes soil Soil makes fuel and food Watering with underground pipes is greywater treatment Operation and gardening creates local jobs Better health, less violence through good nutrition House design follows requirements, beautiful homes, good climate

32 Reuse through productive bamboo systems local regenerative energy, cost recovery through carbon trading and charcoal around 10m²/Person, feed only once a day, distribute well PHYTOREM, France



35 Sorting-Toilet ( Gustavsberg, Sweden) Waterless Urinal (Keramag)

36 Wasserfreie Urinsammlung ist inzwischen in Urinalen relativ problemlos möglich (Fa. Keramag)

37 From Dr. Haiko Pieplow, Ministry of the Environment, Germany Lacto-acid bacteria are added Rottebehälter / Pre-composting tanc 2 filterbags used for 6 month alternately then vermicomposting with biowaste and slice-shred wood (optional)

38 Empty bags all 6 month (3-month intervals or even 1 month can be tested) Compost bag contents with vermi- composting, optional addition of biowaste and slice- cut-woodchip Limited amounts of urine can be added according ot C:N ratio From Dr. Haiko Pieplow, Ministry of the Environment, Germany

39 Conclusions The pathways for modern dry sanitation where found in ancient civilisations A very simple model can serve people who care for virtually no costs Luxury dry toilet models for littel money are feasible Added value trough less water consumption, fertile soil, local gardening options

40 Thank you for your efforts towards a better future! and for listening… further info on IWA SG

41 Old Amazonian cultures All they left was highly fertile soil and beautiful earthware They could produce food with a very low footprint 3-storey agriculture (trees, scrub, ground) They gave us a key element for the future of our societies: urban and peri-urban agriculture can be combined with biowaste utilisation and sanitation
