HONOLULU, HI – JUNE 27, 2019: CarbonCure Technologies (CarbonCure), the global leader in carbon dioxide (CO2) utilization technologies for concrete, has formed a partnership with a second concrete producer in Hawaii, HC&D Ready Mix (HC&D). The 111-year old, locally owned company is the premier concrete producer on the island of Oahu, with a fleet of more than 50 mixer trucks. HC&D also has facilities for aggregate, sand and ready mix concrete production on Maui.  

“We are thrilled to partner with CarbonCure in order to do our part to reduce emissions from the built environment in Hawaii,” says Wade Wakayama, the President of HC&D. “The ability to locally produce low-carbon concrete will allow us to help the State to meet its ambitious CO2 targets and climate adaptation goals.”

CarbonCure’s partnership announcement with HC&D coincides with this year’s United States Conference of Mayors and Climate Mayors Summit in Honolulu, where municipal leaders from across the United States convene to discuss the themes of infrastructure, innovation and inclusion. CarbonCure’s Founder and Chief Executive Officer, Rob Niven, will be attending the event in support of the cities’ plans to lower the embodied carbon footprint of the built environment.

As the world expects to double the current building stock by 2060, cities are faced with the critical climate issue of reducing embodied carbon emissions in the built environment. Hawaii has developed a new model to lower the embodied emissions of concrete by scaling up CO2 utilization technologies without impacting infrastructure budgets or quality. The City and County of Honolulu has demonstrated climate leadership by recently passing a resolution which requests city administration to “consider post-industrial carbon dioxide mineralized concrete for use in all City and County of Honolulu capital improvement projects utilizing concrete.” Climate leadership has also been demonstrated at the state level, with the pending legislature that would require “all state building construction that uses concrete to use post-industrial carbon dioxide mineralized concrete.”

Additionally, the Hawaii Department of Transportation has partnered with CarbonCure partner Island Ready Mix, Hawaii Gas and Matheson Gas to conduct its first infrastructure demonstration of CO2 mineralization for concrete paving on Honolulu’s Kapolei Interchange. The initial pilot demonstration saved 1,500 pounds of carbon emissions, which is equivalent to offsetting the emissions from 1,600 miles of highway driving.

“We’ve seen the benefits to CO2 mineralized concrete and will be using it when appropriate in Hawaii’s road and bridge projects,” says Hawaii Department of Transportation (HDOT) Deputy Director for Highways, Ed Sniffen. “Having a local supplier like HC&D partnering with CarbonCure to provide these materials is a huge step. The availability of environmentally friendly materials such as carbon injected concrete is necessary for HDOT to move forward in reducing the carbon footprint of our construction projects.”

CarbonCure’s Hawaii-based partnerships are supported by Elemental Excelerator, a startup accelerator that provides funding to companies that are capable of improving fundamental systems that affect people’s lives, such as energy, food and agriculture, and transportation. Elemental has provided over $30 million in funding to more than 80 companies to date.



CarbonCure Technologies Inc. is the global leader in carbon dioxide (CO2) utilization technologies for the world’s most abundant man-made material: concrete. The retrofit CarbonCure Technology chemically mineralizes waste CO2 during the concrete manufacturing process to make greener and stronger concrete. CarbonCure has partnered with nearly 150 concrete producers across North America and Asia to create new production cost savings, gain competitive sales advantages and reduce the carbon footprint of the built environment.
