We have invented CO2 Concrete, which is a new process for producing durable and high-strength recycled concrete. We inject carbon dioxide into recycled aggregate to improve its bonding, and thus performance of recycled concrete.

This benefits the environment in two ways:

• Using carbon dioxide which would otherwise be released into the atmosphere, worsening global warming and climate change issues; and

• Reducing landfill space by turning construction waste into construction material, i.e. recycled concrete whose performance is similar to virgin concrete.

This process can bring direct benefits to concrete batching plants as recycled concrete can be effectively used. Many leading concrete suppliers have researched this capability but none have been successful.
