Charbuild - Sustainable building materials with biochar
The construction industry is facing major challenges in reducing its carbon footprint, which requires innovative solutions. The CHARBUILD project focuses on investigating and demonstrating the use of biochar in building materials to address this challenge. Biochar is a carbon-based material produced by pyrolysis of organic material that binds and stores CO2, making it a promising solution for reducing CO2 emissions. In addition, biochar also has the potential to improve indoor air quality by reducing emissions of volatile organic compounds (VOCs) from particleboards.
Through laboratory experiments, prototype development and extensive testing, the project will document biochar's applicability and environmental benefits. A life cycle screening will also be carried out to quantify the potential CO2 savings by using biochar on a large scale.
The project is funded by the INNO-CCUS partnership supported by Innovation Fund Denmark and is running with Project start April 2024, expected completion April 2026.
Goals of the project
The project will demonstrate the potential of biochar as a component in building materials. This is done through a number of sub-goals, including:
- Reduce the carbon footprint by replacing traditional materials in lightweight concrete with biochar.
- Improve indoor air quality by reducing formaldehyde emissions from particleboard.
- Validate biochar's applicability in industrial production processes through testing and prototyping.
- Perform lifecycle screenings to quantify the environmental benefits of biochar.
