o’deep Greening Desert in partnership with the ONG Pro-Natura International is the production and development of biochar, a form of ecological charcoal, also referred to as the “Third Green Revolution”.
Biochar, in its applications, is a simple powerful tool for:
- leading to food self-sufficiency and other applications (for example stopping and reversing desertification),
- tackling climate change on a large scale, ‘one ton of biochar traps 2.7 tons of CO2’,
- significantly increasing the potential for electrification through cogeneration in the most deprived communities, and also
- can be used for waste water and its reuse, soil decontamination or even for building materials & composites as R & D bio-modifier for asphalt cement.
That all is achieved by re-covering unused biomass worldwide, which is equivalent to 12 billion tons every year (Source Pro-Natura International – Member of IUCN, The World Conservation Union).
The diagram below shows the interactions of biochar use:
Initially only used in agriculture, the range of uses for biochar now covers a wide range of different fields, giving this plant-based raw material the chance to make the most of its positive properties. Wherever biochar is speciallly used even for industrial purposes, the carbon taken from the atmosphere in the form of CO2, can be stored for long periods or at least used to replace fossil carbon sources.
The beginning of biochar – example of Terra Preta Cultures :
The char used in former times from natives was not only created just as simple ash but also contained relatively large amounts of charcoal produced at relatively low heat. This char, basically a waste product, was then apparently used as way of preventing infectious diseases. This was done by regularly adding char to other waste in the large jungle settlements, thus sterilising them (see Terra Preta – Model of a Cultural Technique, Schmidt 2011). Once the organic waste has been stabilised through composting or fermenting it with added char, it was later also used as fertiliser on the fields.
