The Global Cement and Concrete Association has shortlisted nine North American participants for the 2023 Innovandi Open Challenge. The program unites startups and member producers to pinpoint innovative ways to cut carbon emissions and accelerate GCCA Net Zero 2050 Roadmap progress. Finalists gain access to association member expertise, plants, labs and networks; those in this year’s Challenge include:

• Arrakis Materials, Woburn, Mass.; carbon-negative materials for concrete mixes
• Chement, Chicago; electrochemical process augmenting cement production
• EnviroCore Inc., Calgary; low-temperature conversion of mineral feedstocks to supplementary cementitious materials
• Enzymatic Inc., Las Vegas; biological process-derived concrete additives
• Louis Structures, Sheboygan, Wis.; municipal waste-derived, lightweight aggregate
• MEP – SeaMix, Miami; portland cement-optimizing basalt fiber and graphene admixture
• Nano Crete, Aurora, Colo.; graphene-based admixture or SCM
• Queens Carbon, Pine Brook, N.J.; reduced-temperature cementitious materials production 
• Ultra High Materials, Washington, D.C.; alumino-silicate alternative to portland cement 

GCCA kicked off the program in 2022, inviting cement process startups, then shifting to concrete materials this year.
