Biochar bricks and green buildings
The document discusses how human activities like population growth, resource use, pollution, and deforestation are straining the Earth's carrying capacity. It then focuses on indoor air quality issues, noting that poor indoor air can be more harmful than outdoor air and cause respiratory problems, especially for children. The document proposes using biochar bricks for green buildings as they emit far infrared radiation, sequester carbon, reduce indoor moisture, and are maintenance free for over 1000 years. It lists various biomass sources that can be used to make biochar including crop residue, cotton stalks, and Prosopis juliflora.
