Biochar is an ancient-like material that is receiving increasing attention due to its beneficial uses in mitigating climate change. The material is commonly used to improve soil quality while simultaneously storing carbon in the long term. Inspired by the principles of traditional cob construction, this is a newly crafted material made primarily of biochar, along with a mixture of mud and straw. As the resulting material is unfired, the pieces can be reintegrated into the soil once their purpose has been fulfilled.

With her ongoing research, ‘Post-Carbon Alchemy’, Carla Alcalà envisions a near future in which communities construct habitable spaces from their own organic waste, which they transform into biochar. These spots function as climatic shelters that attract diverse species, including animals, humans, birds, and insects.
