Regenerate Soils and Stop Desertification
We are a non-for-profit association on a mission to replace agricultural burns by Biochar production, regenerating our soils to stop the desertification of Andalucia

Every year we are experiencing stronger effects of climate change, and these are ever so troubling in the dry region of Andalusia. Sierra Preta aims to contribute in the reconstruction of a resilient ecosystem by reducing further emissions and assisting to remove carbon dioxide from our air.

Biochar fosters adaptation to climate change by restoring soil health, biodiversity, nutrient and water retention. Therefore serving as the perfect tool to reduce both the impact and the frequency of droughts in the region.

During the burning seasons Sierra Preta moves our mobile reactors from land to land so our members can produce Biochar instead of burning their pruning residues. The process of producing high-quality Biochar with our reactors is simple, and we train people so they can do it themselves.

We take care of the transport and maintenance of the kilns as well as the organisation of promotional and awareness-raising activities on the use of Biochar as an alternative to agricultural burning.

Finally, we have several research projects related to the role Biochar production can play in local renewable energy production or water filtration systems.

To achieve our mission, we need your support!

Why BioChar?

Eco System Restoration
BioChar can aid in ecological restoration efforts by improving soil quality in degraded or disturbed landscapes, promoting vegetation establishment.
Climate Change Mitigation
As BioChar sequesters carbon in soils and reduces emissions from organic waste, it can play a role in mitigating climate change by reducing greenhouse gas concentrations in the atmosphere.
Research and Innovation
Ongoing research explores new applications for BioChar. BioChar's versatility and beneficial properties make it a promising tool for addressing environmental and agricultural challenges in various domains.
Renewable
Energy
The pyrolysis process used to produce BioChar can also yield bioenergy in the form of bio-oil and syngas. This can contribute to the renewable energy sector.

 Social Ecological Collective

Our Fundamental principles are not only activities for the environment, open and free access to technology but also social values are extremely important for the way we operate. Our activities have to stand on a social sustainable foundation.

Volunteering is important, but it is also important that people can live off the work they are investing in projects. For this reason we are planning part of our budget into wage and work. We are a collective and for that we are convinced that equal pay is very important. The following criteria will be integrated in the planning of our budget.

  • work will be distributed in an equal hourly rate.
  • work decisions will be made democratically and in consent.
