1st International Terra Preta Sanitation Conference Aug 2013

Location:Hamburg University of Technology. The campus is located in Hamburg-Harburg.

Dates: Wednesday, 28  -  Saturday  31 August 2013

Background

…An analysis of a former civilisation in the Amazon, nowadays Brazil, reveals concepts which enable a highly efficient handling of organic wastes. Terra Preta do Indio is the anthropogenic black soil that was produced by ancient cultures through the conversion of biowaste and faecal matter into long-term fertile soils. These soils have maintained high amounts of organic carbon even several thousand years after they were abandoned. It was recently discovered that around 10% of the originally infertile soils in the Amazon region was converted this way from around 7,000 until 500 years ago. Due to the accumulation of charred biomass and other organic residues, terra preta subsequently formed giving it a deep, distinctly dark and highly fertile soil layer.One of the surprising facts is that this soil is highly productive without adding fertiliser.

Recent research concludes that this culture had a superior sanitation and bio-waste system that was based on source separation of faecal matter, urine and clever additives particularly charcoal dust and treatment steps for the solids resulting in high yielding gardening. Additives included ground charcoal dust while the treatment and smell prevention started with anaerobic lactic-acid fermentation followed by vermicomposting.The generation of new Terra Preta (‘terra preta nova’) based on the safe treatment of human waste could be the basis for sustainable agriculture in the twenty-first century to produce food for billions of people….

from forward

This Resource Book is a guide that seeks to assist individuals, builders, engineers, architects, and policy makers in promoting waterless urinals and the benefits of harvesting urine for reuse through waterless urinals and urine diverting toilets.

Chapters cover a wide set of Waterless Urinals details

  1. Waterless Urinals
    1. 1.1  Advantages of Waterless Urinals and Reuse of Urine
    2. 1.2  Demerits of Conventional Urinals
  2. Functioning of Waterless Urinals
    1. 2.1  Sealant Liquid Traps
    2. 2.2  Membrane Traps
    3. 2.3  Biological Blocks
    4. 2.4  Comparative Analysis of Popular Odour Traps
    5. 2.5  Other Types of odour Traps
    6. 2.6  Installation and Maintenance of Waterless Urinals
  3. Innovative Urinal Designs
    1. 3.1  Public Urinal Kiosk 21
    2. 3.2  Green Waterless Urinal
    3. 3.3  Self Constructed Urinals
  4. Urine Diverting Toilets

Among many topics the Doc  weighs pros and cons of of traps to prevent odor and gases for escaping .Most of the solutions  have cost / maintenance barriers that limit feasibility to particular set of cases. India is a large county and need a variety of solutions as does the rest of the world.
We will  will  be interested to learn more about Zerodor
“An odourless trap Zerodor which does not require replaceable parts or consumables resulting in low maintenance costs has been developed at IIT Delhi. This model is in final test stage yet to be made commercially available.”    more on Zerodor
further notes from forward

Waterless Urinals do not require water for flushing and can be promoted at homes, institutions and public places to save water, energy and to harvest urine as a resource. Reduction in infrastructure required for water supply and waste water treatment is also a spinoff arising from installing waterless urinals. The concept, founded on the principles of ecological sanitation helps in preventing environmental damage caused by conventional flush sanitation systems.

In recent years, Human Urine has been identified as a potential resource that can be beneficially used for agriculture and industrial purposes. Human urine contains significant portion of essential plant nutrients such as nitrogen, phosphate and potassium excreted by human beings. Urine and faeces can also be separated employing systems such as urine diverting toilets. In the light of diminishing world’s phosphate and oil reserves which determine availability as well as pricing of mineral fertilisers, harvesting urine for reuse in agriculture assumes significant importance. Akin to the movement for harvesting rain water, urine harvesting is a concept which could have huge implications for resource conservation.
