Clay Brick Is the Most Sustainable Green Building Material Made
 

Given the significance buildings have on energy consumption, clay brick should be part of a comprehensive green strategy because today’s brick includes:

Inherently Natural Ingredients. Clay brick is predominantly made from clay and shale, which are among the most abundant materials available on earth.
Countless Recycling Options. Clay brick can be salvaged, crushed brick for sub-base materials, and chipped brick for permanent landscaping mulch.
Minimal Waste. Virtually all of the mined clay is used in the manufacturing process making the recycling and waste containment unequalled by any other building material.  In fact, over 80% of our manufacturers re-use their own fired waste material or convert it into other products.  And if you decide to pitch it, there is no special handling required because brick is simply earth, so it’s inert.
Brick is the first masonry material that can attain a “Certificate of Environmental Claims” from a third party source. The National Brick Research Center, has developed a standard to verify the amount of recycled content in clay brick, the utilization of renewable energy in the firing process, and the reduction in the amount of resources used to manufacture brick.
Environmentally Friendly Manufacturing Processes. More than 80% of brick kilns are fired with natural gas, and numerous plants use fuels of bio-based materials from other industrial applications and waste products. Energy sources include methane gas from landfills and sawdust from furniture manufacturers.
Low Embodied Energy to Manufacture Brick. With clay brick’s renowned longevity, no additional energy will be needed to make a replacement brick for many decades – if not centuries. The National Institute for Standards and Technology (NIST) gives brick masonry a 100-year life, and many brick buildings older than a century are still in use today. In fact, brick is one of the few materials that building codes allow to be reused in a building application when it meets the ASTM standard for clay brick. Consequently, salvaged bricks are in high demand and represent a vibrant market.
