Cement and concrete industry invites start-ups to participate in low-carbon innovation challenge

  • Start-ups invited to pitch solutions for industry challenges
  • Focus on areas requiring high levels of technological support and investment, including carbon capture and concrete recycling
  • Selected start-ups will enter 12-month programme with access to expertise and investment
  • Challenge is part of the GCCA’s worldwide mission to provide carbon-neutral concrete by 2050 in line with global climate targets

(London: 18 May 2021) – The Global Cement and Concrete Association (GCCA) has today launched Open Challenge, a global programme to bring together tech start-ups and the cement and concrete industry to help accelerate the development of innovative new low-carbon technologies.

The Open Challenge invites start-ups to pitch solutions to key challenges for the industry that require advanced technology, support and investment and which will have a significant impact on the climate footprint of cement and concrete. The challenge areas include carbon capture technologies, calcination technologies – for heating materials during the clinker manufacturing process -, carbon use in the construction supply chain and improved recycling of concrete.

The industry’s decarbonising mission is vital because the world will need concrete to meet the challenges it faces, including providing safe homes, cities, and a sustainable built environment. Population growth and urbanisation will also mean a greater requirement for critical infrastructure to support resilient communities around the world as well as the global shift to clean and renewable energy such as wind and hydropower.

Dinah McLeod, GCCA Chief Executive said: “Concrete is the most widely used, material on the planet, after water. Our members have committed to drive down the CO2 footprint of the industry’s operations and products, and to deliver on our ambition of carbon neutral concrete by 2050. However, this ambitious goal will require significant and complex changes in how we manufacture, use and recycle concrete. Innovation will be crucial at every stage, from new cement and concrete chemistries to kiln technologies, clinker production, and carbon capture. This Open Challenge will help ensure we are bringing the creativity of the best minds from outside the industry to tackle the climate emergency.”

GCCA and the leading cement and concrete companies it represents have committed to use their resources to help start-ups bring innovation from the pilot stage to commercialisation as part of their work towards realising the industry’s global climate ambition to provide carbon-neutral concrete by 2050.

Claude Loréa, GCCA Cement Director and innovation lead added:We are calling on start-ups, researchers and innovators from around the world to work with us to address the most challenging areas in decarbonising concrete and cement. With the help of Techstars, we’re looking forward to matching outside innovation with industry expertise, which we hope can accelerate the sustainable transformation of the industry. From carbon capture and storage pilots to using CO2 to produce new construction materials, this is a chance to be at the forefront of these innovations which will help the industry to build on its achievement of reducing CO2 emissions by 19% per tonne over the last 30 years.”

GCCA is working with Techstars, the worldwide network that helps entrepreneurs succeed, to source start-ups for the challenge. After the initial sourcing phase, experts from GCCA member companies will partner directly with selected start-ups to develop their technologies, utilising their network, world-class expertise, and facilities as well as potential investment to bring them closer to commercialisation and helping the sector to decarbonise. Selected start-ups will have potential to access to a global cement and concrete market worth $333 billion[1], and a global construction market that is projected to grow to $15.5 trillion worldwide by 2030[2]. GCCA member companies may also consider offering direct investment in select start-ups, though there is no investment requirement for participation in the challenge.

The challenge will be run by the GCCA innovation programme, Innovandi. Launched in 2019, Innovandi also leads the Global Cement and Concrete Research Network, which drives and supports innovation in the cement sector by executing pre-competitive research to improve sustainability and particularly lower CO2 footprint of cement and concrete. The network includes 40 leading global scientific and academic institutions as well as 30 industry partners, from equipment suppliers to admixture producers and academics, working together to produce pre-competitive research aimed at improving sustainability.

About the GCCA

Launched in January 2018, the Global Cement and Concrete Association (GCCA) is dedicated to developing and strengthening the sector’s contribution to sustainable construction. The GCCA aims to foster innovation throughout the construction value chain in collaboration with industry associations as well as architects, engineers, and innovators. In this way, the association demonstrates how concrete solutions can meet global construction challenges and sustainable development goals while showcasing responsible industrial leadership in the manufacture and use of cement and concrete. The GCCA is headquartered in London, England. It complements and supports the work done by associations at the national and regional levels.

Membership to the Innovandi Research Network is open to cement and concrete producers and admixture companies. For more information about joining, visit https://gccassociation.org/innovandi/
