About Us

Mitigating 2 Billion tonnes of CO2 emissions


Our mission is to reduce embodied carbon and permanently store and mineralise CO2 in concrete. C4C technology aims to permanently remove 2 billion tons of CO2 by 2040.


C4C’s technology involves a novel process and method to sequester up to 100 times more carbon than existing solutions for concrete. 


Our technology is suitable for all concrete applications – Ready Mix, Pre-Cast, Structural, Non-Structural and Temporary Applications.



Together we can make a concrete change


Reduction of the embodied carbon in concrete and permanently storing (mineralisation) of CO2 in concrete. Our technology is to permanently remove 2 billion tonnes of CO2 annually by 2025.


Utilising the full natural potential of concrete for the permanent storage of CO2. Our vision is to become the global standard technology for ready-mix and precast concrete production.


Innovative deep science solutions to mitigate the climate emergency.
Enabling the construction industry to meet zero-emission targets.
Pragmatic economically viable engineered solutions for application today.

Our Expert management team

Our team of experts bring a tremendous amount of experience from a variety of fields including construction, process scale-up, commercialisation chemical engineering and industrial experts.


Dr Sid Pourfalah



Sid is a chartered engineer of the institution of civil engineers.  He has 21 years’ experience of innovative and sustainable design, including: research and development for contractors, design firms, construction manufacturers and academic institutes. Sid has built two successful start-ups managing multidisciplinary, large-scale projects (+£100M). In addition, he is an expert in the development and commercialisation of new sustainable products. He is currently a part time research fellow at the University of Sheffield and is also the founder of Concrete4Change, a company that is tackling the climate crisis by reducing the carbon emissions of construction.


Dr. Michael Wise



Michael is a trained Chemical Engineer who started his career like many in the oil industry. He has several publications on Carbon Capture, Storage and Utilisation (CCSU) having developed conceptual technologies for the oil industry. Over the past decade, he has worked in start-ups, developing technologies ranging from gas transportation optimisation, development strategy and commercialisation. He is a Scale-up Specialist having led the R&D projects, piloting and scale-up of three start-up projects worth over £18 million. He has raised £7.9 million in commercial private funding. He is also currently a scale-up advisor at Imperial College.


Dalraj Nijjar



Dal is a commercialisation and growth-hacking expert with 5 years’ experience in early-stage start-up acceleration. He has accelerated the commercialisation of 20 companies in the last 3 years, primarily focusing on decarbonisation of key industries. 4 reached the scale-up stage and Dal helped them raise £5 million in public and private funding. Dal led Warwick Manufacturing Group Accelerator providing growth advisory including business development, business model and commercial initiatives. He successfully has developed growth strategies for over 20 start-ups as shadow CCO. Previous, Dal was an e-commerce start-up founder, marketing consultant to high-growth cloud services companies and analyst at IBM.

Dr. Aisling O'Loghlen



Aisling holds an MS.C in Environmental Management and a Ph.D. in Urban Studies. She is currently project manager for the EU Horizon 2020 funded project GoGreen Routes – €10.5m EU-funded project sowing the seeds for increased nature-connectedness across Europe, Latin America and China with a multidisciplinary consortium of 40 organisations. Previously she held a post as Vice Chancellor’s Research Fellow in Global Challenges based at the Centre for International Development, Northumbria University, Newcastle, where she was Co-Investigator on the ESRC / GCRF Funded project Refugee Youth Volunteering Uganda (RYVU). Her background as a researcher focused on forced migration in developing contexts, which is often a result of climate change.

Transition to Net-Zero Concrete Our concrete is 70% cheaper and 100% greener

Concrete4change (C4C) is an award-winning R&D company on a mission to decarbonise the construction industry. C4C is developing a technology capable of sequestering significant amounts of CO2 in concrete. This technology has the potential to mitigate 2 billion tonnes of CO2 emissions, the equivalent of 4% of global CO2 emissions. Using our technology, we can reduce the production costs of concrete and provide a significant carbon offset market for our product. As a result, our concrete is 70% cheaper and 100% greener compared to conventional concrete. C4C recently won the United Nations most innovative net-zero award at COP-26 and UN SDG award from EU Tech Chamber.
