Biochar is well known for its applications in gardening and landscaping, due to its ability to improve and maintain soil health and help produce robust, thriving plants. The impressive versatility of all-natural biochar also makes it a valuable material for a variety of construction projects.
Uses of Biochar in Construction
Biochar as a building material is a growing trend within the construction industry. Here are a few of the many ways biochar can be used during construction:
Many concrete structures include aggregates, which usually consist of crushed rocks, gravel, and sand. Aggregates are added to the building material to make it stronger and more robust, which ensures structural stability long after the concrete application has been installed.
Using biochar in place of sand or other aggregates can lower the bulk density of concrete while simultaneously increasing the strength of the structure.
All buildings require insulation, which controls the heat transfer between the interior and exterior of a structure. More and more builders are discovering that biochar is a highly effective alternative to conventional insulating materials.
When combined with plaster, biochar maintains optimal interior temperatures, capable of fending off summer heat and cold winter weather. Being an excellent insulator also means that the material works well to reduce noise, which makes it the perfect addition to multi-family dwellings and apartment complexes.
Building Materials Enhancement
Biochar can enhance safety and energy efficiency when used in conjunction with common building materials. For example, biochar acts as a fire retardant when used in concrete, which can help stop the spread of fire in homes and commercial buildings.
The absorbent quality of biochar also helps with moisture control, particularly when it comes to humidity. Water trapped in concrete structures tends to evaporate more quickly when biochar is used over conventional aggregate materials. The result is a cooler, more comfortable environment, along with enhanced energy efficiency for HVAC equipment.
Benefits of Using Biochar in Construction
Biochar is a sustainable building material, helping to reduce greenhouse gas emissions.
Biochar has the ability to sequester carbon, which prevents its release into the air. It also prevents the use of finite raw materials, as biochar is produced by subjecting organic waste products, such as unwanted wood, to ultra-high temperatures to convert it into a carbon-rich material.
Using biochar for construction purposes offers many benefits, including:
- Increased Energy Efficiency – Biochar’s insulating capabilities make it a great material to improve energy efficiency in homes and commercial structures. When building interiors are properly insulated, costs for heating or cooling the space become much more manageable throughout the year.
- Better Water Retention – Biochar’s ability to retain water also makes it ideal when it comes to humidity control. Maintaining the right humidity level inside buildings is crucial when it comes to comfort, but proper humidity control also prevents mold and mildew growth for a healthier environment.
- Reduced Fire Risk – Fire resistant building materials provide peace of mind to building owners, and biochar is effective at inhibiting the spread of fire. Along with enhanced safety, fire resistant materials can also have a positive impact on insurance rates.
- Improved Soil Health – When infused with soil, biochar helps keep moisture and nutrients in place to ensure thriving plants and grass. Biochar also traps carbon in soil, which stops it from being released into the atmosphere and contributing to climate change.
