Biochar, obtained by carbonising organic waste, has many applications, including soil regeneration, an essential tool in the face of climate change, which is already perceptible in many countries, particularly in Africa.


Biochar is obtained by carbonising organic waste. The waste is cooked at high temperatures in the absence of oxygen. 


The resulting biochar is then used as a soil amendment. The soil's ability to hold water and level out nutrients is then rapidly increased. Biochar also promotes photosynthesis so that trees and plants grow faster, absorbing carbon from the atmosphere more quickly.


In addition, increasing rates of drought are weakening soils and crops and making them more vulnerable to pest infestations. Biochar provides an answer to this problem.


Biochar, combined with organic compost, will allow all the elements to work together and create the optimal biology to improve soil health. The addition of biochar accelerates crop productivity rates, improves soil health and retains water so that less water is needed.


The use of biochar for soil regeneration is undeniably linked to greater social justice. By facilitating access to healthy, locally produced food, but also by promoting employment for the population, people living in communities that were once considered 'at risk' are positively impacted.
