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?
At Sierra Preta, we offer a circular and regenerative solution based on the production and application of biochar (a highly stable, plant-based activated charcoal). This material is obtained through pyrolysis—the heating of biomass in the absence of oxygen—avoiding emissions and generating a resource with multiple environmental and agricultural benefits.
Biochar's versatility and beneficial properties make it a promising tool for addressing environmental and agricultural challenges in various domains.
Our Vision is to Regenerate Productive Ecosystems and Stop Desertification.
Social Ecological Collective
Our activities are articulated around core values of social economy, rural empowerment, climate justice, intergenerational equity, and democratic participation. We believe that truly sustainable development is only possible if it is rooted in participatory, inclusive, and fair processes, where rural citizens are not only beneficiaries but also active protagonists of change.
Our proposal not only addresses climate resilience but also generates direct and sustainable local economic impacts. The distributed model we employ allows for flexible and efficient biomass management, adapted to the logistical challenges of rural areas. Therefore, the collection, transportation, and transformation of plant waste into biochar using mobile reactors is a labour-intensive activity, which translates into a tangible opportunity for local job creation.
In this regard, we implement labour policies aligned with the principles of the social and solidarity economy: we implement a single hourly wage, higher than the regional average, and prioritize the hiring of young people, recognizing the high youth unemployment rate in Andalusia and the need to foster decent opportunities in rural areas.
These actions directly contribute to strengthening the local socioeconomic fabric, giving rise to a resilient, green, and socially inclusive circular economy.
We promote a regenerative economy ecosystem, supporting agroecological entrepreneurship through training in practices such as regenerative agriculture and the production and distribution of biochar and its by products. We encourage the incorporation of related initiatives as members of the association to strengthen synergies and support local business initiatives. Our goal is for farmers, technicians, young people, and local entities to find in these practices not only environmental solutions, but also diversified, stable, and sustainable sources of income.
Environmental education, scientific dissemination, and knowledge transfer are essential pillars of our work. Through equitable access to information through workshops, training, and open resources, the knowledge generated by Sierra Preta is distributed horizontally. To date, we have organized four community workshops and ten practical training sessions for farmers, teaching them how to produce their own biochar and apply it effectively on their farms. These activities build local capacity and technical sovereignty, in line with climate justice objectives.
