Waste and recycled materials can create high-performance bricks that don’t need energy-intensive kiln firing.

Waste and Renewables Make for Better Bricks

Brick is one of the most commonly used building materials worldwide.

Typically made of a clay mixture and then kiln fired, brick is usually made from local resources and requires straightforward building techniques which have, in most cases, gone unchanged for generations. Kiln firing of bricks greatly strengthens them, but uses vast quantities of wood, coal, natural gas, and other fuels. Brick-making also pumps an average of 1.4 pounds of carbon into the atmosphere per brick, and creates air pollution in developing countries such as India and China.

Alternative options for materials can address these issues, however, while also making use of waste materials.

Building Materials Can Clean Polluted Air

Titanium dioxide can be added to roofing and concrete to neutralize oxides of nitrogen.

Building Materials Can Clean Polluted Air

Oxides of nitrogen are harmful components of air pollution, contributing to the formation of ground-level ozone and fine particulate pollution that cause respiratory issues in humans.

A common mineral, research shows, can neutralise the pollutants when added to projects in the built environment.

Nitrogen oxide (NO) and nitrogen dioxide (NO2), together referred to as oxides of nitrogen or NOx, are components of air pollution produced by combustion of fossil fuels in vehicles, power plants, and off-road equipment. Australia’s Department of the Environment lists electricity production and motor vehicles as the largest NOx polluters, at 36 per cent and 26 per cent of emissions, respectively.
