TPS 2013 – International Terra Preta Sanitation Conference, Hamburg, Germany

The 1st International TPS Conference took place on the 28st to 31st of August 2013. It was well-attended and there were many vibrant discussions about TPS. Resources from the conference are now available on this page.



Introduction to TPS

Terra Preta Sanitation is an issue of growing concern in the light of water and sanitation, climate change, energy and soil protection. The International Terra Preta Sanitation Conference aims at bringing scientists and practioners together to present their results and share their experiences.

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, and could lead to attaining a number of major Millennium Development Goals at the same time.

Conference Themes

The conference focused on the nexus around soil, energy and WASH. Please find below the conference themes:

  • TP soils – historical and modern aspects
  • Soil fertility and food security
  • Intensification of organic farming
  • New insight to plant-soil interaction (endocytosis)
  • Land use, reforestation, reversing erosion
  • Overall systems and system design
  • Greywater in TPS – Bamboo, short rotation plantation, constructed wetlands
  • Logistic and operation
  • Microbiology, sanitization and lactic acid fermentation
  • Carbon composting of biowaste and excreta
  • Wood gas technology for energy and char coal production
  • Pyrolysis vs. hydrothermal carbonization
